Pool gear has a way of multiplying. One summer of floats, goggles, towels, test kits and chemical jugs can bury a deck, and anything left out in the open fades, mildews or gets washed away in the first hard rain. That is why the best outdoor storage cabinets for pool supplies have become one of the highest-return purchases on any poolside shopping list.
We worked through the leading resin deck boxes, vertical cabinets and sheds and compared them on the things that decide whether a cabinet survives a pool environment: material, gallon capacity, interior dimensions, door closure, and whether the hardware survives a leaking chlorine jug. Every pick below lists its rating and its review count, because several listings in this category show a near-perfect score off a handful of reviews, and a number like that tells you almost nothing.
One warning before we start. Almost everything sold as a waterproof outdoor storage cabinet is actually weather resistant, which means water resistant rather than submersible. That difference decides where you can put it, and we cover it in the buying guide along with a clear plan for storing pool chemicals so your hinges do not end up streaked with rust. Updated for 2026.

Everything in that table is covered in detail below, grouped so you can skip straight to the format you need. If you are still building a storage plan rather than shopping, our guides on garage storage cabinets for tools and storage cabinets for garages cover the indoor side of the same problem.
1. Keter Westwood 150 Gal – The Most Room For Cushions and Floats
Keter Westwood 150 Gal Outdoor Storage Box for Patio and Pool Accessories
150 gallon resin
61 x 28.3 x 25.2 inch
39.1 pounds
Hydraulic piston lid
Pros
- Holds full cushion sets and pool floats
- Quick ten to twenty minute build
- Quiet hydraulic lid
- Lockable hasps
- Seats two adults
Cons
- Molded walls are thinner than on heavier Keter boxes
- Prolonged direct sun degrades the resin
- Assembly order matters
This is the box we keep coming back to. At 61 by 28.3 by 25.2 inches it takes a full season of patio cushions, several pool noodles and a stack of towels in one go, and at 39.1 pounds it is still light enough to walk around the deck alone.
The hydraulic piston is the feature that changes daily use. The lid stays up on its own while you dig through the contents and closes quietly rather than crashing shut, which matters when you are grabbing a towel with wet hands and a kid is three feet away.
Owners consistently report finishing the build in ten to twenty minutes with no tools, and the wood-grain resin pattern reads as furniture rather than equipment. It is water resistant, not waterproof, so towels and cushions are the right load.
Lockable front hasps are a genuine bonus on a deck box, since most of this format has no security at all. With more than fourteen thousand reviews on record, this is also the most thoroughly documented unit in the group, which matters when you are choosing something that sits outdoors year round.
Is 150 gallons too big for a small deck?
The footprint is the real constraint, not the volume. You need a clear patch roughly six feet long that is not a walkway and not directly under a splash zone.
If your deck is tight, the 71 gallon Marvel below uses half the length and holds a complete cushion set for most four-chair tables. Go bigger than you need only if you store floats and gear for more than one property.
What will not go in this box
Do not park a jug of muriatic acid in a resin box with a lift lid. The resin shrugs off chlorine far better than it shrugs off repeated acid contact, and the closure does nothing to contain a spill if something tips during a storm.
Keep dry goods in the Westwood and put chemicals in a lockable vertical cabinet with a base tray. That split also keeps heavy jugs on the bottom of a separate unit, so the piston lid is not lifting several hundred pounds every time you open it.
2. Keter Marvel 71 Gal – Best Value for a Full Cushion Set
Keter Marvel 71 Gal Outdoor Storage Box for Patio and Pool Accessories
71 gallon resin
45.9 x 17.4 x 22.2 inch exterior
15.6 pounds
Tool-free assembly
Pros
- Tool-free snap build in about five minutes
- Waterproof rated
- Light enough to move alone
- Wood-look finish resists fading
- Lockable
Cons
- Lightweight plastic feels thin when empty
- Bottom panel carries a modest load
- Prolonged sun makes plastic brittle
The Marvel is the most reviewed product in this roundup with 16,596 ratings at 4.3 stars, and that track record comes from people using it for exactly what we are testing it for. One box holds the cushions from a typical four-seat patio set plus towels and a bag of floats.
Assembly is the standout. It is a tool-free snap-together build that most owners finish in about five minutes, and the connectors are shaped so parts are hard to seat incorrectly, which is more than we can say for most flat-pack resin products.
It is also the only unit here rated waterproof rather than water resistant, and owners report dry contents through heavy rain. Interior dimensions of 44.6 by 15.6 by 20 inches mean a rolled towel fits along the back wall without bending.
At 15.6 pounds you can drag it across the deck single-handed to chase the sun, which is worth more than it sounds when cushions mildew in one shaded corner all season.
Will the lightweight plastic sag under wet cushions?
The concern about a 15.6 pound box is warping, and it is fair when the box is empty. Once loaded with wet cushions the structure tightens up, and the most repeated comment across those reviews is that a cheap-looking box turns out sturdier than expected.
Check the bottom panel before you load it, since that flattest surface takes the least weight. Distribute a heavy load rather than stacking all of it in one corner, and it will hold its shape season after season.
How does it handle direct sun?
This is the clearest limitation in the reviews. Prolonged, unprotected sun makes the plastic brittle over time and can eventually crack the hinges, so a shaded position against a wall beats an open stretch of deck.
If your only option is full sun, step up to a heavier multi-wall resin model such as the Westwood, which has more material in the panels to absorb the same exposure.
3. Greesum 31 Gal Lockable Box – Best for Small Patios
Greesum Outdoor Storage Box 31 Gallon Storage Box with Lid for Patio Furniture, Garden Tools, Pool Supplies, Waterproof and UV Resistant, Lockable, Dark Black
31 gallon resin
22.04 x 16.34 x 20.87 inch
Padlock hasp
Waterproof rated
Pros
- Snaps together with no tools
- Contents stay dry in storms
- Light enough to reposition
- Resin shows little fading
- Padlock hasp
Cons
- Light enough to tip in strong wind
- 31 gallons suits odds and ends
- Seats about one light adult
This is the answer for balconies, porches and patios where a 150 gallon box will not fit. It measures just over 22 by 16 by 21 inches and carries 31 gallons, which is enough for towels, a test kit and a couple of floats rather than a whole cushion set.
It is also one of the few small boxes with a real padlock hasp. That changes the calculation for a shared pool, an apartment complex or any deck where gear has a habit of walking away between visits.
Owners rate the water resistance highly, reporting dry packages after heavy storms, and 3,116 reviews at 4.5 stars is a solid sample for a box at this size. The finish has held up without visible fading or cracking in regular use, according to the review pattern.
It assembles tool-free in one box with the hardware included, so there is no second trip to a hardware store before you can use it.
Will it blow over on an open deck?
This is the limitation we would weight most heavily. The unit weighs 4.8 kg and has a small profile, so owners in windy locations report it can be knocked over in a strong gust unless it is anchored or weighted down.
Set it against a wall or rail rather than in the middle of an open deck, and put something heavy inside if you cannot secure it. A cabinet that tips into the pool is worse than no cabinet at all.
Is 31 gallons enough to be worth buying?
For towels, goggles, testing supplies and a small inflatable ring, yes. You will not fit a full set of patio cushions or a stack of pool noodles, so treat it as a poolside caddy rather than the whole storage plan.
If your outdoor space is tight but you want cushion storage too, the 82 gallon Greesum below takes four chair cushions and still measures under four feet long.
4. Suncast 54 cu ft Vertical Shed – Best for Long-Handled Tools
Suncast Outdoor Storage Shed, Water Resistant Resin Vertical Outdoor Storage Cabinet for Patio, Garden Tools, Cushions, & Equipment, Weatherproof Multi-Wall Design, 54 cu. ft., Made in USA
54 cubic foot resin
32.5 x 53 x 71.5 inch
102 pounds
Padlock-ready doors
Pros
- Tall profile fits rakes and umbrella poles
- Reinforced floor holds heavy items
- Lockable handles and lower latch
- Clean taupe finish
- Vertical footprint saves yard space
Cons
- Poorly printed assembly instructions
- Water resistant rather than waterproof
- Needs anchoring and a level base
- Two-person assembly advised
When a rake handle will not go in a deck box, this is the format you actually need. At 71.5 inches tall with 54 cubic feet of space, it takes long-handled tools, patio umbrellas, a grill cover and the bulky gear that makes horizontal boxes useless.
The reinforced floor is the detail that separates it from cheaper resin sheds. It is built to take heavy items resting on the base rather than on a thin panel, and 1,709 reviews at 4.4 stars come from owners who put real weight in it.
Security is handled twice over, with padlock-ready door handles plus a lower resin latch, so it is one of the few units here that locks properly rather than relying on a magnet. That also makes it a better choice than a deck box for securing pool chemicals.
It is made in the USA, which is a reasonable proxy for parts availability if a panel cracks years from now, and the taupe finish sits against a fence without looking like temporary equipment.
Is it actually waterproof?
No, and the listing says so: it is water resistant. Owners report the panel corners do not meet tightly enough to stop driven rain, so anything that must stay dry belongs inside a sealed bin within the shed.
Do not store pool chemicals directly on the floor either. Use a leakproof secondary container and keep it clear of the door, where splash and handling tend to concentrate.
How hard is this to put together?
Plan for two people and about an hour. The most repeated complaint is that the assembly diagrams are printed so faintly they need a magnifying glass, which makes an otherwise straightforward build feel confusing.
It also needs a level platform for the doors to sit and seal correctly, and owners in exposed locations anchor it to a wall and floor. Set the level base before you start building rather than after.
5. Keter Store-It-Out Prime Shed – Two 32 Gallon Bins and Pool Gear
Keter Store-It-Out Prime 4.3 x 3.7 ft. Outdoor Resin Storage Shed with Easy Lift Hinges, Perfect for Yard Tools, Pool Floats and Garden Accessories, Black
4.3 x 3.7 ft resin shed
28 x 52 x 44.7 inch
Hydraulic pistons
French doors
Pros
- Wide shallow interior takes two 32 gallon bins
- Hydraulic lift-off lid
- Ventilation panels and flexible locking
- Holds pool floats and garden gear
Cons
- Lowest rated unit in our group
- Resin panels can warp over time
- Screws strip in plastic during assembly
- Needs a level base
The defining feature here is the bin-opening kit. Raise the hydraulic lid and the included kit lifts the lids on two 32 gallon trash cans, so this one unit covers pool floats, garden tools and the bins you drag to the curb.
It is a wide but shallow shed at 52 by 28 inches on the ground with a 44.7 inch height, and the French doors open the full width so you can load a bulky float without angling it. Ventilation panels keep the interior from turning into a damp closet.
We want to be straight about the ratings here. At four stars from 1,933 reviews, this is the lowest-scoring Keter unit in our group, and the reviews explain why. Assembly is fiddly because the sides, back and lid have to be aligned at the same time, and several screws strip in the plastic.
Add the reports of resin panels warping over time and one owner describing the shed coming apart in high wind, and the picture is clear. It is a capable box with a mediocre build, and the price of that convenience is patience on assembly day.
Should you buy a lower-rated shed?
Only if the bin-opening feature solves a problem you actually have. If you are storing chemicals and want maximum security, the 26 cubic foot lockable cabinets further down do that job with fewer moving parts.
The locking options here are flexible rather than strong. Owners describe them as deterring casual theft, not a determined intruder, so do not rely on this for a shared pool where chemicals are the target.
What do the stripped screws mean in practice?
It means assembly technique matters. Owners report needing to drill out stripped screws, so drive them with a hand screwdriver rather than a driver on high torque, and align every panel before tightening anything.
On a level base the doors sit flush and the warping complaint largely disappears, which is why we would not rule this unit out, but we would not build a chemical storage plan around it either.
6. Greesum 82 Gal Box – Best for Patio Cushions
Greesum Outdoor Storage Box 82 Gallon Storage Bin with Lid for Patio Furniture, Garden Tools, Pool Supplies, Waterproof and UV Resistant, Lockable, Black
82 gallon resin
45.66 x 20.86 x 23.22 inch
30 pounds
Waterproof rated
Pros
- Holds four chair cushions and more
- Interior stays dry through windblown rain
- Strong enough to seat two adults
- Lockable holes
- Finish looks more expensive than it is
Cons
- Lightweight build can feel flimsy
- Some lids arrive damaged or do not seat flush
- Base panel is easy to install upside down
- Thin internal hardware
This is the middle ground between the 31 gallon box and the 150 gallon Westwood, and it is the one we would buy for a typical four-seat patio. At 45.66 by 20.86 inches it holds four chair cushions plus floats and towels without claiming a huge run of deck.
Owners report the interior staying dry through blowing rain, snow and ice, and the waterproof rating is on the listing rather than inferred. It is also rated to hold two adults, so it doubles as a step or a seat at the pool edge.
The feedback is genuinely split, and we would rather say so than cherry-pick. Around 1,100 reviews at 4.2 stars, with many owners describing a sturdy, dry, good-looking box that also handles a large volume of firewood, and a smaller group reporting cheap-feeling construction and cracking.
Two practical checks help. Inspect the lid on arrival, because some units arrive damaged or will not sit flush and then let water in, and read the base panel diagram carefully since it is easy to fit upside down.
How do I avoid a leaking lid?
Seat the lid fully closed before loading it, and check that the hinge latches pull and snap evenly on both sides. A lid that rocks or needs force to close will admit windblown rain no matter how good the seal looks.
Treat the internal hardware gently when closing. Reviews describe it as thin, and forcing a loaded lid is the fastest way to bend the hinge bracket.
Is 82 gallons right for a four-seat patio?
For four dining chairs, yes. Cushions for eight or more seats, plus floats and towels, will overflow it, and at that point the 150 gallon Westwood is the better buy despite the larger footprint.
It is also the right size if you want a box you can move. At 30 pounds it is a two-person lift in a full state but still manageable, unlike the 102 pound Suncast shed.
7. Mrosaa 60 Gal Cabinet – Best for Tight Side Yards
Mrosaa Outdoor Storage Cabinet Waterproof with Shelf,Resin Storage Sheds Outdoor Cabinets for tub Towels/Chemicals/Grill Items/Patio/Garden/Backyard, Size 34.3”L*15”W*36.2”H（Black）
About 60 gallon resin
34.3 x 15 x 36.2 inch
One shelf included
HDPE rustless body
Pros
- Only 15 inches wide for narrow side yards
- HDPE resin resists water and UV
- Shelf keeps items off the floor
- Assembles in 20 to 30 minutes
- Surfaces hose down easily
Cons
- No latch
- so doors can swing open
- Single-hinge doors can bow over time
- Only one shelf included
- Hard to reposition once loaded
At 34.3 by 15 by 36.2 inches this is the narrowest true cabinet in the group, and that single dimension is the reason to buy it. A 15 inch footprint slides along a side yard, against a house wall or into the gap beside a fence where no deck box will go.
It is a vertical cabinet with a shelf, so hot tub towels, grill accessories and pool supplies sit in two levels rather than one deep well. The HDPE resin body is rustless and colorfast, and 558 reviews at 4.4 stars rate the looks well above what this category usually offers.
Assembly is one of the better ones we tested, taking about 20 to 30 minutes with clearly photographed instructions, and the smooth surface rinses clean with a hose. That matters more than it sounds next to a cabinet that has held pool supplies all season.
The design flaw is the missing latch. There is no catch or magnetic hold, so the doors can swing open on their own and let in water and pests, and single-hinge doors can bow until gaps open at the top and bottom.
Can you store pool chemicals in a cabinet with no latch?
Not ones that matter. Without a latch a gust or a nudge from a dog can leave the doors open, and a cabinet that cannot stay closed is not a safe place for acid or for a child who has learned how to open gates.
Use it for towels, cushions, toys and grill gear, where a slightly ajar door is an inconvenience rather than a hazard. For chemicals, choose a lockable unit.
Is one shelf enough?
For towels and daily pool gear, yes. For a full inventory of test supplies, chemicals and tools, no, and add-on shelves for this cabinet are expensive compared with buying a unit that ships with three.
Also plan around the fact that it rests on its base rather than being fixed down, so once you fill it with liquids you will not want to reposition it. Choose the spot before you build it.
8. SoliWood Cedar Potting Bench – A Poolside Work Surface and Cabinet
Outdoor Storage Cabinet & Potting Bench Table with Metal Top, Wooden Patio Furniture, Garden Workstation (Classic Grey, 36x31x17in)
Cedar and metal
17 x 31 x 36 inch
200 pound load capacity
Two layer cabinet
Pros
- Genuine cedar with a water-based grey stain
- Metal top doubles as a potting bench
- Pilot holes and pre-assembly speed the build
- Two layer cabinet space
Cons
- Strong stain odor lingers for weeks
- Occasional fit and finish defects
- Metal top marks and stains easily
- Light duty for heavy repeated use
This one is different from the rest of the list. It is a potting bench with a cabinet underneath, so you get a flat metal work surface for opening chemical containers, rinsing test vials and cleaning filter parts, plus enclosed storage below.
For an owner who does maintenance poolside, that work surface is the point. A deck box gives you somewhere to put things; this gives you somewhere to work on them at 36 inches high, with the storage built in underneath.
The build is quick. Most small parts are pre-assembled at the factory and pilot holes are drilled, so owners put it together in about 20 minutes, and the 510 reviews at 4.3 stars praise the genuine cedar and the farmhouse look against a furnished deck.
Be aware this is wood outdoors, not resin. Cedar needs a sealer to stay grey, and the water-based coating gives off a strong odor that some owners report lingering for weeks, especially if you assemble it indoors.
Is cedar good next to a pool?
It looks the best of anything on this list and it is the only natural material here, but it is also the only one that needs annual attention. Plan to reseal or re-oil it each spring, and expect raised grain near a splash zone.
Keep the open cabinet section for dry goods and cushions, and use the metal top as the wet work area so you are not setting damp items on wood.
How much weight can the top take?
The listed load capacity is 200 pounds, which is fine for bags of pool salt and a few toolboxes. Owners also report the top marks and stains easily, so use a mat for anything wet or gritty.
Fit and finish varies. Some buyers report rough pieces, splits in the door wood and misaligned screw holes, so inspect the parts before you set the assembly in its permanent spot.
9. Devoko 26 cu ft Lockable Cabinet – Best Low-Profile Deck Storage
Devoko Outdoor Storage Cabinet 26 Cu Ft with Lockable Doors, Horizontal Storage Shed Waterproof Patio Tools Storage Box for Sofa Cushions, Gardening Tools and Accessories (White)
26 cubic feet
25.5 x 48 x 37.1 inch
61.7 pounds
Lockable sliding doors
Pros
- Low horizontal profile stays under windows
- Lockable sliding doors
- Foot switch and top magnet closure
- Double layer blow-molded HDPE panels
- Waterproof resin body
Cons
- Built-in shelves sold separately
- Accessories add extra cost
- Sliding doors need a clear track in front
This is a horizontal cabinet, wider than it is tall, and that shape is the whole point. At 48 inches wide but only 37.1 inches tall it fits under a window, beside a fence or along a low wall where a tall shed would block the view.
It is also one of the few here with genuine lockable sliding doors, plus a foot switch and top magnet so the doors close firmly without you squatting down. That combination is what makes it a candidate for securing chemicals around children and pets.
The body is double-layer blow-molded high-density polyethylene with UV protection and a listed waterproof rating, and 26 cubic feet is enough for cushions, a weed whacker and sports gear in one unit. Reviewers rate it at 4.2 stars across 464 reviews.
The drawback is stated plainly in the listing: shelves are not included and must be bought separately. So is the foot switch pin and other accessories, which means the cabinet arrives less usable than most of the group.
Is it worth buying extra shelves?
Only if you plan to use the upper half. Without a shelf the contents sit on the base as one open volume, which works fine for cushions but wastes the 37.1 inch height for anything that benefits from being stacked.
Buy the shelf if you are storing chemicals in jugs, since separating them from the floor is the safest arrangement. Skip it if the unit is just holding patio furniture over winter.
How much door clearance do sliding doors need?
Plenty, and this is the planning step people miss. The doors slide across the front face, so you need clear, level ground roughly the width of the cabinet in front of it, and that space cannot double as a walkway.
If you have only wall space to work with, choose a swing-door unit like the 26 cubic foot Greesum below or the Suncast wicker cabinet, which need door swing clearance instead of a slide lane.
10. Suncast 97 Gal Wicker Cabinet – Best for Pool Chemicals
Suncast Lockable Outdoor Cabinet Storage for Patio, Garden and Backyard, 97 Gal, Cool Gray
97 gallon resin
42 x 23 x 35.5 inch exterior
52 pounds
Padlock-ready doors
Pros
- Predominantly plastic hinges avoid rusted metal failures
- Handles pool chemicals and hot tub supplies
- 97 gallons with an adjustable shelf
- Wicker look suits a furnished deck
- Two compartments wipe clean
Cons
- Some predrilled holes missing or only imprinted
- Doors may need adjusting or re-drilling
- Wall panels should be screwed to the base
This is our pick for pool chemicals, and the reason is specific: the hinges and much of the hardware are plastic rather than metal. Corroded, rusted hinges are the most reported failure in this category, and pool owners describing exactly that pattern with cheaper cabinets are easy to find on pool forums.
It is a two-door vertical cabinet at 42 by 23 by 35.5 inches with 97 gallons of space and one adjustable shelf, so you can keep chemical jugs on the lower level and hot tub supplies above without stacking a heavy jug on a hinged lid.
Owners specifically report that it handles pool chemicals and hot tub supplies without corrosion problems, which is not a small claim in this category. At 4.5 stars from 248 reviews the sample is modest, so weigh that accordingly, but the finish is the best-looking option here on a furnished deck.
Wiping it down with a damp cloth is the whole maintenance routine, and the two-compartment interior keeps chemicals and towels from sharing space.
Is the wicker look resin or real wicker?
It is resin panels moulded with a wicker-style pattern, not woven wicker over a frame. That is the point: it looks woven but it will not rot, harbor mildew or need reweaving, and it survives a humidity level that a natural material would not.
The look is closer to a modern patio cabinet than a rustic one, so it suits contemporary and charcoal-toned deck furniture particularly well.
What about the assembly problems owners report?
The consistent complaint is missing or unmarked predrilled holes, which makes the shelf supports and door pins hard to place, and some doors need re-drilling to fit. Budget extra time and check the parts against the manual before you start forcing anything.
One worthwhile upgrade is to screw the wall panels into the base yourself. They are designed to drop into place without fasteners, and a few owners report the assembled unit feeling flimsy until it is secured.
11. Greesum 26 cu ft Two Door Cabinet – Best Lock for Pets and Kids
Greesum 26 CUFT Outdoor Storage Cabinet with 2 Lockable Doors, White
26 cubic feet
25.4 x 47.6 x 37 inch
55.8 pounds
Foot operated lock
Pros
- Foot operated bottom lock keeps pets out
- 26 cubic feet fits chairs umbrella and cooler
- White styling blends with a deck
- Resin resists wind rain UV and corrosion
- Concave side armrests make it liftable
Cons
- Shelves not included
- Top magnet aligns poorly and seals loosely
- Some panels arrive out of fit
- Strong resin odor on a minority of units
Locking is the headline here. The foot-operated bottom lock closes the unit without you squatting, which is exactly what you want when the contents are chemical jugs and a dog is waiting for the door to open. Two lockable doors and a resin body complete the security picture.
At 26 cubic feet it is a real family-sized unit. Owners report fitting beach chairs, a patio umbrella and a cooler in one, and 175 reviews at 4.2 stars show a consistent, if lightly sampled, experience.
The white classic styling is the other reason to like it. It reads as garden furniture rather than industrial storage, so it does not look like equipment dropped beside a pool, and the concave side armrests are a genuinely clever way to lift and reposition it.
Resin also means no rusting, no UV chalking and no repainting, which is the maintenance argument that keeps surfacing in pool owner discussions where metal cabinets are described as rusting within a season.
Does the top magnet actually seal?
Not reliably. Owners report the top magnet closure aligning poorly and not holding a tight seal, so the upper part of the door line is the most likely place for water to get in during windblown rain.
Treat it as water resistant rather than waterproof, and put anything that must stay dry in a lidded bin inside. The foot lock at the bottom still holds, so security is unaffected.
What about missing shelves and fit issues?
Shelves are not included, only the brackets are supplied, so budget for a shelf if you want two levels. Some panels also arrive out of fit, which makes assembly harder than the hour the build should take.
A minority of owners report a strong burnt-plastic or fishy odor that transfers to contents. Air the unit out for a day or two after assembly before you store anything sensitive to smell.
12. PetsCosset 33 x 16 x 66 in Cabinet – Best for Shelf Configuration
PetsCosset Outdoor Storage Cabinet with Shelves, Wood & Plastic Garden Shed, Weatherproof Outside Tool Cabinet for Patio, Backyard, Pool
33 x 16 x 66 inch
38 pounds
Three adjustable shelves
Fir frame with plastic panels
Pros
- Tall 66 inch design in a small footprint
- Three adjustable shelves reconfigure freely
- Slanted roof sheds water and raised legs keep the base drier
- Fir and plastic build looks less utilitarian
- Built in under 40 minutes
Cons
- Long term durability of the wood and plastic mix is questioned
- Lock is sold separately on most variants
- Raised legs leave more exposed space underneath
The height is the selling point. At 66 inches tall and only 16 inches deep, it uses vertical space in a way no other unit in this roundup does, and three adjustable shelves let you move the dividers to fit tall tools, cushions or small items without buying more storage.
The slanted plastic roof sheds water rather than letting it sit flat, and the raised legs with foot covers keep the base drier than a unit sitting flat on the deck. That is a real advantage in a place where water pools.
The fir frame with plastic panels also looks less like a utility shed than an all-resin box, which owners with furnished gardens mention as a deciding factor. Assembly is one of the quickest here, with clearly labeled parts and step-by-step instructions getting it built in under 40 minutes.
At four stars from 280 reviews it is one of the lower-rated units we include, and the reviews explain the reason. Owners question the long-term durability of the wood and plastic combination outdoors, and the magnetic door closure is the only latch on most variants.
Will fir wood hold up outdoors year round?
It is the biggest question mark. Fir is a softwood and it will check and grey faster than resin, so expect the frame to need inspection each spring and possibly a coat of sealant if you live somewhere with hard winters or a humid climate.
Resin panels will outlast the frame. That is a fair trade for a unit that blends into a garden, but it is a different maintenance commitment from a resin box with nothing to maintain at all.
Is it lockable out of the box?
There is a lockable latch, but on most variants the lock itself is sold separately, and the double doors otherwise close with heavy-duty magnets. Plan on adding a padlock if the unit will hold chemicals or anything a child could reach.
With the raised leg design, keep a ground-level tray under the base if you store liquids, since the open space underneath is more exposed than on a flat-base cabinet.
Storing Pool Chemicals Safely in an Outdoor Cabinet
Pool chemicals destroy outdoor storage, and the damage shows up as green corrosion, rust streaking and seized hinges that then let rain into the cabinet. The rules below are what keep a cabinet in working condition for more than one season.
Never store muriatic acid or any acidic product in a cabinet with metal hinges, metal shelving or steel fasteners. Chlorine is fairly tolerant of resin, but repeated acid contact corrodes hardware and leaves rust streaks down the door frame that do not come off.
Keep chemicals in their original labeled containers and place them in a leakproof secondary bin on the cabinet floor. A secondary container is the difference between one cracked jug and a destroyed cabinet, and it lets you move everything at once when you add shock to the pool.
Store chemicals low, towels high and toys in the middle. This keeps several hundred pounds of liquid at the base where the structure is strongest and prevents a heavy jug from dropping onto a hinged lid or a plastic shelf.
Use a cabinet that actually latches or locks if children or pets are around. A foot-operated lock, a magnetic catch with a separate lock, or a padlock-ready hasp are the three options we saw, and only the first two held up well in owner reports.
Shade and ventilation both matter. Heat accelerates the breakdown of chlorine products, and a ventilated interior stops trapped humidity from turning the inside into a mildew pocket during a wet week.
One final note on what not to store. Aerosol cans, food, pressurised containers and bare electronics do not belong in a poolside cabinet, where heat and humidity will damage them regardless of cabinet quality.
How to Choose an Outdoor Storage Cabinet for Pool Supplies
Choose the material first, then the format, then size. Everything else on this list is refinement, and getting those three wrong means buying a cabinet that rusts, will not fit, or is too small for what you actually store.
Resin and high-density polyethylene is the right default for poolside use. It will not rust, it does not need sealing, and it tolerates chlorine splashes better than anything else. The trade is appearance and, in cheaper units, wall rigidity.
Treated or natural wood looks the best and needs the most work. Cedar and similar woods need resealing each spring to hold color and resist the humidity a pool area produces, so choose wood only if you enjoy that annual task.
Galvanized steel and rattan both have real drawbacks here. Ungalvanized steel rusts within a season in a humid poolside environment, and rattan or wicker over a frame traps moisture in the weave. Avoid both right beside a pool.
Format follows the load. A deck box with a lift lid wins on wet, bulky gear you reach for daily. A hinged or sliding deck box adds a latch and security. A vertical cabinet with doors and a shelf wins on chemicals, towels and anything you want hidden. A shed is the only format that fits long-handled tools.
For vertical cabinets, a narrow footprint of around 15 inches is the difference between fitting beside a house and not fitting at all. The Mrosaa at 15 inches wide is the narrowest we tested.
Size by gallons first and interior dimensions second. A four-seat patio set needs at least 80 gallons of cushion space, and a family storing floats, towels and chemicals together wants 90 gallons or more.
Interior dimensions tell you what actually fits. A rolled towel needs roughly 20 inches of length, pool noodles need close to six feet, and a gallon jug needs a shelf that will hold its full weight rather than a thin plastic panel.
Check how the door closes. Padlock-ready hasps, foot switches and magnetic catches are the three common options, and the reviews in this roundup were clear that magnets alone are not enough for a shared pool.
Always buy shelves. Several cabinets in this roundup ship with brackets but no shelves, and a chemical jug sitting directly on the cabinet floor is the arrangement we would avoid.
Place the cabinet on a level surface, off the ground and clear of the splash zone. A level concrete pad or a paver base stops doors from sitting unevenly, which is the most common reason water gets in, and it keeps standing water from collecting underneath where mildew starts.
Allow for door clearance before you buy, not after. Swing doors need an arc of clear deck, sliding doors need a clear lane the width of the unit, and a cabinet that blocks a walkway will annoy you by the end of the first week.
Suncast vs Keter: which outdoor storage brand wins?
Keter wins on review volume and choice, and Suncast wins on lockable cabinet design. Keter models here carry between 14,745 and 16,596 reviews, while the Suncast units range from 248 to 1,709, so Keter has a far better documented track record for resin outdoor storage.
Keter offers more formats, from a 31 gallon box to a 150 gallon bench box, and its hydraulic piston lids are the smoothest in this roundup. Suncast builds true vertical cabinets with working padlock hardware, which most resin competitors in this list do not.
For a family that stores towels, cushions and floats, we would pick Keter. For a household storing pool chemicals where hardware corrosion is the main risk, we would pick the Suncast wicker cabinet, and we would still anchor either brand to a level base.
Neither brand is a bad choice. The honest summary is that Keter has more units across a wider range of capacities while Suncast has better cabinet hardware, and if you also need indoor units for the same gear over winter, our guide to vinyl storage cabinets covers that side.
Frequently Asked Questions
What are some good storage options for pool items?
Six formats cover most poolside storage. A deck box with a lift lid suits wet gear, towels and cushions, and many double as bench seating. A hinged or latched deck box adds security for shared pools. A vertical cabinet with doors and a shelf keeps pool chemicals enclosed and works in narrow side yards. A storage shed is the only format that fits long-handled rakes and umbrella poles. A potting bench with enclosed storage gives you a work surface for maintenance. A rolling cart needs no assembly and suits small patios or covered areas.
What is the best outdoor waterproof storage cabinet?
For most buyers the Keter Westwood 150 gallon box is the best outdoor waterproof storage cabinet, holding cushions, floats and towels with a hydraulic piston lid and lockable hasps. Note that it is water resistant rather than fully waterproof, so keep chemicals out of it. If your priority is genuinely waterproof construction, the Keter Marvel 71 gallon box and the Greesum 82 gallon box both carry a waterproof rating on their listings.
What is the best outdoor storage container for pool chemicals?
The Suncast 97 gallon wicker-look cabinet is the best outdoor storage container for pool chemicals, because its hinges and most hardware are plastic rather than metal, which is what fails and rusts when acid and chlorine are stored together. Pair it with a leakproof secondary bin on the cabinet floor and a padlock on the doors. The 26 cubic foot Greesum and Devoko cabinets are also lockable alternatives.
Which is better, Suncast or Keter?
Keter wins on review volume, format choice and hydraulic lids, with between 14,745 and 16,596 reviews on the models we tested. Suncast wins on lockable cabinet hardware and build quality for vertical units. For towels, cushions and floats, choose Keter. For securing pool chemicals where corrosion is the main risk, the Suncast wicker cabinet is the better pick.
How do I keep pool chemicals safe in an outdoor cabinet?
Never store muriatic acid or acidic products in a cabinet with metal hinges or shelving, since the result is green corrosion and rust streaking that destroys the hardware. Keep chemicals in their original labeled containers inside a leakproof secondary bin, place that bin on the cabinet floor, and store towels above and toys in the middle. Use a cabinet with a real latch or lock where children or pets are present, and keep the unit shaded and ventilated.
Do outdoor storage cabinets get moldy?
They can, particularly when the interior holds damp towels or cushions and the doors stay shut. Resin cabinets resist mildew because nothing absorbs water, but trapped moisture still causes musty smells. Leave resin units slightly ajar after a wet swim session, wipe the interior down, and use desiccant packs for long-term storage. Wood cabinets such as cedar need the most attention here, since the grain holds moisture and needs resealing each spring.
How big should my pool storage cabinet be?
For a four-seat patio, 80 gallons covers the cushions plus towels and a few floats. A family storing floats, chemicals and towels together should look at 90 gallons or more. Add capacity if you store a full season of pool noodles, since they need close to six feet of length. Check interior dimensions as well as gallons, because a tall narrow cabinet and a wide shallow one hold very different items.
Is resin or metal better for outdoor pool storage?
Resin is better in almost every case near a pool. It will not rust, it needs no sealing or painting, and it tolerates chlorine splashes. Metal units with a galvanized coating can work in dry climates, but ungalvanized or thin-gauge steel is the most common complaint we found among pool owners, who describe rust and corroded hinges within a single season. Resin costs you some wall rigidity and some visual refinement, not durability.
Can I put a lock on a resin deck box?
Yes, if the unit has lockable holes or a hasp. In this roundup the Greesum 31 gallon box, the Greesum 82 gallon box, the Keter Westwood 150 gallon box and the Keter Marvel 71 gallon box all have lockable points, and the Suncast and Devoko cabinets go further with full lockable doors. The padlock is normally not included, so add it as a separate purchase.
Do I need to seal a wooden pool storage cabinet?
Yes. Any wood unit used outdoors, including the cedar potting bench in this roundup, needs sealing or oiling at least once a year and often twice in humid climates. Resin and HDPE cabinets need no sealing at all, which is the main reason owners replace wood units after a few seasons. If you dislike annual maintenance, choose resin and accept the more utilitarian appearance.
Our Verdict: Which Outdoor Storage Cabinets for Pool Supplies to Buy
The Keter Westwood 150 gallon box is our top pick and the reason is simple: with 14,745 reviews at 4.5 stars it has the best documented combination of capacity, a hydraulic lid that stays open on its own, and lockable hasps, and no other unit here matches those three things at once.
Buy the Keter Marvel 71 gallon instead if you want the same brand at roughly half the volume and the most reviews in the roundup. Buy the Suncast 97 gallon wicker cabinet if pool chemicals are going inside, since its plastic hinges are the reason it will not corrode the way a cheaper cabinet does.
For everything else, match the format to the job. Deck boxes for wet gear and cushions, a shed for tools, a narrow vertical cabinet for a side yard, and a potting bench if you want somewhere to work. Whatever you choose, put it on a level base, buy the shelves, and keep acid out of any unit with metal hardware.
