A poolside gets cluttered fast. Between floaties, chlorine bottles, skimmer nets, extra towels, and a stash of goggles that always seems to vanish, your deck turns into a landing zone by mid-summer. A dedicated outdoor pool storage box solves the mess while keeping chemicals out of the sun and rain. The picks below cover small stowaway bins, dual-purpose benches, and oversized deck boxes built for the full seasonal haul. Every option here uses weather-resistant resin (a tough molded plastic that shrugs off UV rays and rain), so you can leave them outside year-round without watching them warp or rust.
The Main Contenders
Suncast 22-Gallon Small Deck Box (Light Taupe)
Keter Westwood 150 Gal Outdoor Storage Box
EFU 60 Gallon Waterproof Deck Box (Black)
GULAIMOAO 80 Gallon Storage Bench (Black)
ATMELT 160 Gallon Waterproof Deck Box
GULAIMOAO 80 Gallon Storage Bench (Grey)
GULAIMOAO 80 Gallon Storage Bench (Dark Grey)
GULAIMOAO 80 Gallon Storage Bench (Matte Black)
GULAIMOAO 80 Gallon Storage Bench (Charcoal Grey)
Why These Options Stand Out
The Suncast 22-Gallon Small Deck Box is the kind of grab-and-go bin that earns its spot on a tight patio. It measures roughly 22.5″ x 18″ x 20.5″, which is small enough to slide beside a chair without crowding the walkway, and the hinged lid flips open smoothly so you can toss a wet towel inside before it drips across the deck.
Because the shell is molded poly resin (a rigid plastic that resists moisture), this box shrugs off splash-out from the pool and holds up through summer storms. The neutral light taupe tone blends with most patio sets, and the sloped lid channels rainwater off instead of pooling on top. For anyone renting a place without a shed, this is the most forgiving entry point in the roundup.
Reasons It Performs
- 22-gallon capacity swallows pool toys, chemicals, and folded towels without dominating a small deck.
- Water-resistant poly resin fights rust, fading, and mildew, so it survives wet poolside duty.
- Hinged lid opens with one hand, useful when the other arm is carrying a float or a dripping kid.
- Lightweight build makes it easy to drag to a new spot when the sun moves.
- Doubles as a casual side seat for slipping sandals on before a swim.
Honest Caveats
- No lock point, so it’s not the right home for valuables around curious kids or visitors.
- Smaller footprint means a full seasonal stockpile won’t fit; plan on rotating gear.
- Plastic shell can scuff on rough concrete over the years, depending on how you drag it.
Key Specs
Who It Suits Best
Small-space dwellers with a modest pool kit who want a no-fuss, easy-to-move bin.
Where Another Pick Suits Better
The Keter Westwood 150 Gal Outdoor Storage Box fits households storing an entire season of gear in one place.
When your pool setup includes a vacuum hose, a cover reel, half a dozen floats, and a couple of chemical jugs, the Suncast 22-gallon simply isn’t big enough. The Keter Westwood 150 Gal Outdoor Storage Box is built for that “store everything in one trip” moment. At 150 gallons, it swallows a full season’s worth of patio cushions and pool accessories without making you Tetris them into place.
The deck-friendly styling mimics wood grain, so it reads more like furniture than a plastic bin. The closed lid supports the weight of two people, turning the top into a casual bench when towels need to come off. It also locks, which makes a real difference in shared backyards where you want to keep pool chemicals away from kids. Compared to the smaller Suncast we just covered, this is a generational leap in capacity, not just a step up.
Everyday Perks
- 150-gallon interior holds pool chemicals, floats, cushions, and toys in a single container.
- Closed lid supports two-person seating, so the box doubles as deck bench space.
- Lockable design adds a layer of safety around curious hands.
- Wood-look finish blends with traditional patio furniture rather than screaming “plastic bin”.
Trade Offs
- Large footprint demands a real corner of the deck, not a balcony nook.
- Heavier than compact bins, so you’ll want to plan placement before filling it.
- Wood-look panels are cosmetic; the build is still resin, which can show scuffs over time.
Right Fit For
Large backyards where one container needs to handle every pool accessory in the rotation.
Look Elsewhere When
Apartment patios with strict space limits fit better with the Suncast 22-Gallon Small Deck Box.
The EFU 60 Gallon Deck Box lives in the middle of this list for a reason. It offers more room than a starter bin without demanding the footprint of a Keter Westwood. At 60 gallons, you can park a couple of floats, a stack of towels, and a chemical caddy inside, all while the box doubles as a spot to perch while lacing up water shoes.
The build is polypropylene resin (a slightly tougher cousin of the basic poly resin used on smaller bins), and EFU markets it as waterproof with UV protection built into the panel. That combination matters poolside, where the sun bakes plastic all afternoon and a stray splash lands on everything. The black finish hides scuffs better than lighter tones, which is a quiet win for a box that lives outdoors year-round. For most backyards, this is the volume sweet spot.
The Case For It
- 60-gallon capacity handles typical family pool kits without overflowing.
- Polypropylene resin resists rust, dents, and peeling in humid pool air.
- UV-protected panels reduce the chalky fade that hits cheaper plastic in full sun.
- Closed lid supports seated use, so the box works as a bench between swims.
- Black finish disguises everyday scuffs and dust.
Points To Keep In Mind
- No integrated lock point, so add a padlock or keep it on a private deck.
- Smaller than the 150- and 160-gallon options if your gear stockpile runs deep.
- Resin panels can feel light before the box is loaded, so anchor it on windy days.
Made For
Couples or small families who want a mid-size, weatherproof pool storage bin without overspending.
Skip It When
Households storing a cover reel or oversized floats will be happier with the ATMELT 160 Gallon Waterproof Deck Box.
The 80 Gallon Outdoor Storage Bench from GULAIMOAO leans into the “sit and stay a while” side of pool life. The molded armrests give it a real furniture feel, so it reads more like a deck chair than a storage bin. When the lid is closed, you’ve got a comfortable spot to towel off after a swim, and the 80-gallon interior hides away the rest of the clutter.
Three steel bars reinforce the structure, which is the kind of detail you don’t see on flimsy resin boxes. The weather-resistant resin handles sun and rain, and the lockable lid accommodates a padlock for keeping chemicals away from kids. Compared to the Keter Westwood we just covered, this trades a bit of capacity for stronger seating ergonomics and a more residential look.
Everyday Advantages
- 80 gallons of hidden storage swallows pool toys, cushions, and a chemical caddy.
- Integrated armrests add a furniture-grade feel for poolside seating.
- Lockable lid (padlock not included) secures chemicals and small valuables.
- Three internal steel bars stiffen the box beyond standard resin builds.
- Weather-resistant shell stands up to sun, rain, and seasonal temperature swings.
Some Limits To Know
- Padlock is not included, so plan on buying one to use the lockable feature.
- Larger footprint than compact bins; measure your deck before committing.
- Resin seat can feel warm in direct afternoon sun until it cools down.
Best Suited To
Pool owners who want a real seat with armrests plus hidden storage in a single footprint.
Another Choice May Suit
The EFU 60 Gallon Waterproof Deck Box is a friendlier fit for tighter decks where bench depth feels excessive.
The ATMELT 160 Gallon Waterproof Resin Deck Box is the deep-storage answer for households that have already outgrown a mid-size bin. The polypropylene resin body and the included support rod make the lid feel sturdier than the typical hinge-and-pray setup you get on cheaper boxes. Open it up and you have room for cover reels, a vacuum hose, floats, and a stack of folded chairs without compressing anything into a wrinkled mess.
ATMELT’s design leans on a ventilated interior, which helps moisture escape instead of pooling against stored cushions. The UV-protected shell fights the chalky fade that hits most outdoor plastic after a couple of summers. Among the largest options in this roundup, only the Keter Westwood comes close in total volume, and the included support rod is the kind of detail that hints at heavier, daily use. Most families will use this and stop opening the garage for pool gear at all.
The Practical Payoff
- 160-gallon interior swallows cover reels, hoses, floats, and seasonal gear in one container.
- Support rod reinforces the lid, useful if kids treat the box like a bench.
- UV protection keeps the color from going chalky under full sun.
- Ventilated design reduces trapped moisture on stored cushions and towels.
- Polypropylene resin resists dents and rust in coastal or humid climates.
Where It May Fall Short
- Large footprint requires a generous deck or patio corner.
- Heavier empty weight than mid-size bins, so plan placement before loading.
- Color options skew toward neutral, which is safe but not distinctive.
Whose Shelf It Belongs On
Large backyards with substantial pool gear inventories who want one container to rule them all.
Swap It Out When
Smaller decks and modest gear lists are happier with the GULAIMOAO 80 Gallon Storage Bench.
The grey version of the GULAIMOAO 80-Gallon Storage Bench is the chameleon of the bunch. At roughly 52″ L x 23″ W x 35″ H, it slips into most deck arrangements without shouting for attention, and the soft grey finish pairs with both warm wood tones and cooler contemporary furniture. Functionally, it shares the same bones as its darker siblings: lockable lid, weather-resistant resin, and armrests that make the closed top a real seat.
What’s distinct here is the aesthetic flexibility. If your deck already mixes grays, whites, and natural wood, a charcoal or matte black box can feel too heavy. The grey tone stays quiet in the background. It still stores 80 gallons of gear, supports seated drying-off, and resists UV and rain, but it does so without becoming the visual centerpiece of your patio.
Why It Works Well
- Neutral grey finish blends with mixed-color patio sets.
- 80-gallon interior handles a full family of pool accessories.
- Lockable lid (padlock sold separately) secures chemicals from curious hands.
- Armrests and full-width seat work for two people drying off together.
Things To Consider
- Padlock is not included, which is easy to forget at checkout.
- Lighter grey shows dust more than the matte black or charcoal versions.
- Same large footprint as the other GULAIMOAO benches; measure your space first.
Perfect Match For
Decks with mixed furniture palettes that need a storage bench to fade into the background.
Reach For A Different Pick When
Households wanting a bold, design-forward statement piece fit better with the GULAIMOAO 80 Gallon Storage Bench in Matte Black.
The dark grey GULAIMOAO bench reads as the more grown-up sibling of the standard grey version. The deeper tone is closer to charcoal than to silver, which makes the box feel like a deliberate furniture choice rather than a utility bin. For decks with black railings, dark wicker, or slate tile, the color match is noticeably cleaner than the lighter grey.
On the inside, you’re still getting 80 gallons of lockable storage, weather-resistant resin, and the same armrest-equipped seat as the rest of the GULAIMOAO lineup. What changes is the visual weight. It grounds the corner of a deck rather than receding into it, which is a plus if your patio feels washed out and a minus if your space already trends dark.
Useful Highlights
- Dark grey finish coordinates with modern deck palettes and black hardware.
- Lockable lid accommodates a padlock for chemical safety.
- 80-gallon interior holds pool toys, towels, and a chemical caddy with room to spare.
- Full-width seat with armrests is comfortable for drying off between swims.
Practical Considerations
- Darker finish absorbs heat in full afternoon sun, so the seat can run hot.
- Same large footprint as the other 80-gallon benches in this lineup.
- Padlock is not included, so plan on adding one to use the lock feature.
Who Will Love This
Homeowners with darker, contemporary patio sets who want the storage bench to feel intentional.
Not Your Match When
Bright, sun-drenched decks with light wood furniture pair better with the GULAIMOAO 80 Gallon Storage Bench in Grey.
The matte black GULAIMOAO 80 Gallon Storage Bench is the boldest finish in this lineup, and that’s the point. Matte black outdoor furniture has become a design staple for modern decks, and a storage bench in the same finish ties the whole space together without making it look like an afterthought. The non-glossy surface also helps disguise the inevitable scuffs that come from daily pool use.
Inside, you get the same dependable 80 gallons, lockable lid, weather-resistant resin, and armrests found across the GULAIMOAO family. Functionally, this is a twin of the dark grey and grey versions, but visually it lands as the strongest statement piece. If you want your storage to read as part of the furniture rather than as a bin, the matte black finish is the version to pick.
Everyday Wins
- Matte black finish matches modern outdoor furniture trends.
- Lockable lid keeps chemicals and small valuables out of reach.
- 80-gallon interior handles a typical family’s pool gear with room to spare.
- Matte surface hides minor scuffs better than glossy finishes.
Worth Bearing In Mind
- Matte black absorbs heat in direct sun, so the seat can feel warm to the touch.
- Padlock is not included, which is easy to overlook.
- Same large footprint as the other 80-gallon options in this roundup.
Built With In Mind
Design-focused homeowners with modern outdoor furniture who want a storage bench that blends into the aesthetic.
Consider Something Else When
Full-sun decks where seating gets uncomfortable may be happier with the lighter GULAIMOAO Grey version.
The charcoal grey GULAIMOAO 80 Gallon Storage Bench is the softest of the darker finishes, sitting between the standard grey and the dark grey. It has just enough depth to feel grounded on a deck, but it doesn’t read as a black box the way the matte version does. That makes it the easiest match for a wide range of furniture palettes, from weathered teak to painted wicker.
Functionally, you get the same 80-gallon storage, the same armrests, and the same lockable lid as the rest of the GULAIMOAO lineup. The resin shell holds up to UV exposure and rain, and the lid supports seated use between swims. If you’re choosing between four colorways of essentially the same bench, the charcoal grey is the safe, design-flexible default.
Where It Delivers
- Charcoal grey bridges light and dark deck palettes without clashing.
- 80-gallon interior holds the typical pool gear rotation.
- Lockable lid (padlock not included) secures chemicals and small items.
- Armrests and full-width seat support comfortable post-swim seating.
Small Caveats
- Padlock is not included and must be purchased separately.
- Same large footprint as the other 80-gallon GULAIMOAO benches.
- Resin seat can warm up under direct afternoon sun, depending on exposure.
The Right Fit
Households torn between lighter and darker finishes who want a low-risk, design-flexible bench.

Households chasing maximum capacity are better served by the ATMELT 160 Gallon Waterproof Deck Box.
Choosing the Right Size and Material for Your Poolside
Pool storage boxes live a harder life than most outdoor furniture. They take direct sun, splashed chlorine, drips from wet bodies, and the occasional kick from a pool noodle. Start by measuring the spot where the box will sit, then measure again with the lid open, because the swing arc matters more than people expect. A 150-gallon box that fits closed can still block a doorway when you lift the lid.
Material is the next decision. Resin, polypropylene, and poly variants all resist water and rust, but UV protection is what separates a box that looks fine after two summers from one that turns chalky by August. Heavier resin panels also resist warping, which matters if anyone in your household plans to actually sit on the closed lid rather than treat it as off-limits.
Lockable lids earn their keep around pools. Chemicals like chlorine tablets and shock treatments are dangerous around small children, and a simple padlock turns a curious-kid magnet into a sealed unit. Ventilation matters too, because trapped moisture is what makes stored cushions smell like a wet dog by August.
Pool Storage Boxes Buying Checklist
Capacity first. A 22-gallon bin works for a few floats and a chemical caddy. Family-sized setups with cover reels and vacuum gear need 80 gallons or more.
Lockable lid. Pool chemicals and curious hands don’t mix. A padlock-compatible latch is a small feature that prevents big problems.
UV-protected resin. The single biggest predictor of how a plastic box looks after a couple of summers. Skip it and the color fades fast.
Bench or not. Dual-purpose boxes trade some interior volume for a closed lid that supports seated use. Worth it if deck seating is tight.
Footprint and lid arc. Measure the spot, then measure it with the lid open. The swing arc surprises people on narrow decks.
Where Shoppers Go Wrong
The most common mistake is buying too small. A 22-gallon bin looks generous in the warehouse photo, but once you add a chemical caddy, two floats, and a stack of towels, it’s full. Measure your actual gear list before picking a size, and round up rather than down.
Another trap is ignoring UV protection. Two boxes that look identical in a listing can differ dramatically after one summer of full sun. The version with explicit UV-treated panels ages more gracefully. Finally, don’t forget the padlock. Lockable lids are common on this category, but the padlock is almost always sold separately, and a box without one is a frustration waiting to happen.
Why Premium Boxes Cost More
The jump from a basic 22-gallon bin to a 150- or 160-gallon deck box isn’t just about size. Larger boxes use thicker resin panels, internal steel reinforcement, and support rods that prevent the lid from sagging over time. They also tend to include better UV protection and more refined finishes that hold up to years of direct sun.
For households with serious pool gear, the upgrade pays off in longevity and storage. For casual pool owners with a couple of floats and a single chemical bottle, a mid-size box like the EFU 60-gallon is often the smarter spend.
Frequently Asked Questions
What size outdoor pool storage box do I need? A 22-gallon box handles a couple of floats and a small chemical caddy, while 80 to 160 gallons suits families with full seasonal gear, vacuum hoses, and cover reels.
Are resin pool storage boxes waterproof? Most quality resin boxes are water-resistant and shed rain off the sloped lid, but ventilation is what keeps the interior from trapping moisture on stored cushions and towels.
Can I sit on a pool storage box? Many mid- and large-size boxes are designed to support seated use on the closed lid, and reinforced models with support rods handle regular sitting well.
Do pool storage boxes need a lock? A lockable lid is strongly recommended around children because pool chemicals like chlorine tablets are hazardous and should stay out of reach.
How do I keep a pool storage box from fading? Look for UV-protected panels and consider placing the box where it gets some afternoon shade to slow the cosmetic wear over time.
The Takeaway
The right outdoor pool storage box depends on how much gear you actually have and how much deck space you’re willing to give up. A 22-gallon bin handles a weekend floatie stash, a 60-gallon mid-size suits most couples, and 80-gallon benches or 150- to 160-gallon monsters serve full family setups. Pick the size that matches your real gear list, and don’t skip the padlock if chemicals are going inside.
