Deck cushions rot when they sit in the wrong container. A proper outdoor storage bin fixes that with a sealed lid and UV-stabilized resin. If you’re also weighing outdoor storage boxes, a waterproof outdoor storage box, an outdoor storage bench, an outdoor storage cabinet, or a full-size outdoor storage shed, the five bins below cover 30 to 150 gallons of sealed capacity. All resin. All built to shrug off a wet season.
How We Evaluated
I ranked each bin on measured capacity, resin thickness against ASTM G154 UV exposure guidance, lid seal quality, and load rating for double-duty seating. Assembly time and weight came second. Ratings and specs reflect current manufacturer data.
Devoko 30 Gallon Resin Deck Box Waterproof Outdoor Storage Box with Seating - Lockable, UV Resistant, Black
Pros
- Extremely affordable for waterproof, lockable storage solution
- Lightweight enough to carry one-handed yet sturdy enough to sit on
- Tool-free assembly makes setup effortless for anyone
- Versatile placement indoors or outdoors thanks to weather resistance
- High review volume (3,600+) with a strong 4.5-star average signals consistent quality
Cons
- No support rod to hold the lid open, so you need one hand free when reaching inside
- 30-gallon capacity is too small for large cushions or bulky items
- PP resin material may look less premium than wood or wicker alternatives
This little deck box punches above its weight. At under9 pounds, you can pick it up with one hand and drop it wherever you need extra storage or an impromptu seat. The black resin looks clean and unobtrusive on a patio, balcony, or tucked beside a front door, and the waterproof shell means you never have to rush outside to rescue cushions before a rainstorm.
What sets it apart from pricier options is how thoughtfully the basics are covered: it locks, it resists UV fading, the edges are rounded for safety, and you can sit on it comfortably. It is not trying to be a statement piece. It is trying to solve a problem quietly and affordably, and it does exactly that.
If you want reliable outdoor storage that doubles as seating without spending more than dinner for two, this one delivers.
Styles it works with: Modern Minimalist, Industrial, Contemporary Patio, Utilitarian
Best placed in: Small apartment balcony, beside a back door for garden tool access, poolside for towel and toy storage, inside a garage or mudroom
May not suit: Large patios where the compact size looks out of scale, or spaces styled with natural materials like rattan and teak where black resin would feel out of place
Buy it if:
- You need a quick, affordable storage solution for a small patio, balcony, or porch
- You want a dual-purpose box that works as overflow seating for guests
- You store lightweight items like pool toys, gardening gloves, or throw pillows and need them protected from rain
Consider waiting if:
- You need a larger capacity (Devoko offers 80, 100, and 120 gallon versions if you can spend more)
Skip it if:
- You need to store full-size patio cushions or large equipment that won't fit in 22x16x20 inches
- You want a lid that stays open on its own with support rods for hands-free access

Pros
- 150-gallon interior fits large items like lounge chair cushions and pool floats
- Hydraulic pistons enable smooth, easy-open and quiet close
- Sturdy lid supports two average adults sitting comfortably
- Weather-resistant resin needs no painting or staining
- Wood-plank texture looks more upscale than plain plastic deck boxes
Cons

- Resin surface can feel hot to the touch in peak summer sun
- Assembly is required and side panels can feel thin until fully locked together
If you have ever tripped over scattered pool noodles or watched your patio cushions get soaked in a surprise rainstorm, the Keter Westwood deck box is the kind of upgrade that pays for itself in one season. The wood-plank texture gives it a surprisingly upscale look for a resin piece, and it reads more like a designed bench than a plastic storage bin when placed against your deck railing.
In everyday use, it earns its keep in multiple ways. The hydraulic pistons lift the lid smoothly so you can toss in cushions with one hand, and the flat top is sturdy enough to serve as extra seating for two adults at a backyard gathering. Inside, the dry and ventilated space keeps mildew at bay, so your soft goods come out fresh instead of musty.
If you want the warmth of real-wood deck storage without the staining, warping, and fading, this one delivers.
Styles it works with: Modern Farmhouse, Transitional, Coastal, Rustic
Best placed in: patio corner, deck edge, poolside or garden shed area
May not suit: small balconies or compact patios where 61 inches of length feels overpowering, or homes wanting a true natural-wood aesthetic up close
Buy it if:
- You need to store large patio cushions, pool floats, or garden tools in one weatherproof spot
- You want storage that doubles as comfortable seating for two adults at outdoor gatherings
- You like the wood-plank look but do not want the upkeep of real wood
Consider waiting if:
- You need a specific color beyond dark grey to match your existing patio furniture
Skip it if:
- Your patio or balcony is too small for a 61-inch-long unit
- You need heavy-duty security for high-value items, since the resin walls are not impact-proof

This deck box solves one of the most annoying outdoor living problems: where to stash bulky patio cushions when a storm rolls in or summer ends.

1. Keter Westwood 150 Gal — the one that wins on sealed capacity
This one wins. The Westwood holds 150 gallons, enough for two full cushion sets plus pool floats, and the wood-panel resin texture hides scuffs better than flat finishes. It supports up to 660 pounds, so it doubles as bench seating for two adults. The hydraulic-hinge lid stays down in wind and lifts without a fight. Keter builds it from weather-resistant polypropylene rated against UV fade. At roughly 60 pounds assembled, it’s stable but not something you’ll relocate weekly. Best for patios that need real volume in one footprint.
2. Devoko 100 Gallon Resin Deck Box — the value workhorse
The 100-gallon Devoko splits the difference between the giant Keter and compact bins. It’s rated waterproof with a lipped lid that channels rain off the seam, and the resin panels resist cracking through freeze-thaw swings. Capacity lands near 100 gallons, plenty for cushions, garden tools, and kids’ pool gear. Load rating supports seated use, though it’s firmer than the Keter’s cushioned-feel lid. Assembly runs about 20 minutes with snap panels. If you want maximum volume per dollar, this is the honest pick.
3. Keter Kentwood 92 Gal — the balanced mid-size
The Kentwood delivers 92 gallons in a footprint that fits smaller decks and balconies. Same weather-resistant resin as the Westwood, with a 507-pound seat rating for two people. The lid seals tight against driven rain, and the neutral gray panels won’t clash with existing furniture. It’s lighter than the 150-gallon model, so repositioning for cleaning is easy. Good for households that want Keter build quality without committing to the full 150-gallon bulk. The trade-off is capacity you may outgrow if you store bulky floats.
4. Devoko 78 Gallon Deck Box — the compact sealer
At 78 gallons, this Devoko suits tight patios and apartment balconies where floor space is tight. The resin is waterproof-rated with a lid lip that keeps interior contents dry through storms. It handles cushions and a modest tool load without crowding a walkway. The build is lighter than the larger Devokos, which helps if you move it seasonally. It won’t seat two adults comfortably, so treat this as storage-first. A clean choice when square footage matters more than raw volume.
5. Devoko 30 Gallon Resin Deck Box — the small-space specialist
The 30-gallon Devoko is the smallest here and the most portable. It’s waterproof resin, sized for a single cushion stack, garden hand tools, or pool chemicals kept off the ground. Indoor use works too, since the finish stays neutral. At this capacity it’s an accent piece rather than a primary store. The lid seals against splash and light rain reliably. Pick this for a compact balcony, an entryway drop zone, or as a second bin beside a larger unit.
Comparison Table
| Bin | Capacity | Seat Rating | Best For |
|---|---|---|---|
| Keter Westwood | 150 gal | 660 lb | Large patios |
| Devoko 100 Gal | ~100 gal | Seated use | Value volume |
| Keter Kentwood | 92 gal | 507 lb | Mid-size decks |
| Devoko 78 Gal | 78 gal | Storage-first | Compact patios |
| Devoko 30 Gal | 30 gal | Accent | Balconies |
What to Check Before You Buy
Capacity is the headline number, but the lid seal decides whether your cushions stay dry. Look for a lipped or overlapping lid that channels water off the seam. Resin thickness matters against UV: panels stabilized to ASTM G154 exposure hold color far longer than untreated plastic.
Seat rating tells you if the bin doubles as seating. Anything above 500 pounds handles two adults. Below that, treat it as storage only.
Weight cuts both ways. Heavier bins stay put in wind, but 60-pound units resist seasonal repositioning. Match the mass to how often you’ll move it.
Keter vs Devoko: Which Brand Fits You
Keter leans premium. Higher seat ratings, textured wood-look panels, and hydraulic hinges push the Westwood and Kentwood ahead on refinement. You pay more per gallon for that finish and the stronger lid mechanics.
Devoko competes on price and volume. The 100-gallon model gives you the most sealed space per dollar in this group, and the smaller 30 and 78-gallon bins solve space-limited setups Keter doesn’t target as directly. Both brands use waterproof-rated resin. Choose Keter for seating-grade builds and Devoko when capacity and budget lead.
Frequently Asked Questions
Are resin outdoor storage bins fully waterproof?
Most are water-resistant rather than submersible. A lipped lid keeps rain off contents, but seams aren’t gasket-sealed. Store items you’d protect from splash and driven rain, and elevate the bin so groundwater can’t pool underneath.
Can I sit on an outdoor storage bin?
Only if it carries a seat rating. The Keter Westwood holds 660 pounds and the Kentwood 507, both fine for two adults. Devoko models vary, so verify the load number before using one as a bench.
Will resin fade in direct sun?
UV-stabilized resin resists fading for years. Panels evaluated against ASTM G154 exposure hold color longest. Untreated plastic yellows and grows brittle within a season or two, so confirm UV stabilization in the specs.
How much capacity do I actually need?
One cushion set fits in roughly 70 to 100 gallons. Add pool floats or bulky tools and you’ll want 150. For a single seat pad or hose, 30 gallons handles it without wasting deck space.
Do these bins survive winter freeze-thaw?
Quality resin flexes through freeze-thaw cycles without cracking. Empty water first so nothing freezes solid inside. Leave the lid slightly vented in storage to prevent trapped moisture and mildew on stored fabric.
How long does assembly take?
Snap-panel resin bins go together in about 15 to 25 minutes with no tools beyond your hands. Larger 150-gallon units take longer for panel alignment. Keep the instruction sheet handy for lid-hinge orientation.
Bottom Line
The Keter Westwood 150 Gal wins outright: 150 gallons of sealed space, a 660-pound seat rating, and Keter’s weather-resistant resin make it the most versatile bin here. Step down to the Devoko 100 Gallon if you want the most capacity per dollar and don’t need cushioned-feel seating. One caveat across the group. None are fully submersible, so elevate them and treat the lid seal as splash protection, not a dry vault.
