If your patio cushions, pool floats, and garden tools have taken over the garage, you need more outdoor storage — and the right container depends entirely on how much volume you’re trying to clear, not how it looks on a showroom floor. A resin deck box gets you the lowest cost per cubic foot of the three. A storage bench earns its keep by doubling as actual seating. A small resin shed exists for households whose overflow has outgrown bins altogether. Match the box to what you’re storing and how much floor space you’re willing to give up, and the right size becomes obvious fast.
At a Glance: Which Outdoor Storage Pick Fits You
- Best Overall — Keter Solana 70-Gallon Storage Bench ($199.99): the only one of the three that’s also furniture — weatherproof storage underneath, real seating for two on top.
- Best Budget — Suncast 134-Gallon Deck Box ($189.00): the lowest entry price and the lowest cost per cubic foot of storage of any option here.
- Best Upgrade — Keter Signature Vertical Storage Shed ($754.99): 50 cubic feet of locked, dry space for a household that has outgrown bins entirely.
Deck Box vs. Storage Bench vs. Small Shed: Comparison Table
All three are built from weather-resistant resin, but they solve different problems. Here’s how the specs actually stack up, pulled from each manufacturer’s current listing.
| Product | Price | Capacity | Footprint / Dimensions | Material | Weatherproofing |
|---|---|---|---|---|---|
| Suncast 134-Gallon Extra Large Deck Box | $189.00 | 134 gal. (≈17.9 cu. ft.) | 55″W x 28.5″D x 27″H (≈10.9 sq. ft. footprint) | Weather-resistant resin, wicker-look finish | All-weather resin shell, hinged lid |
| Keter Solana 70-Gallon Storage Bench | $199.99 | 70 gal. (≈9.4 cu. ft.) | 54.6″L x 23.4″W x 32.8″H (≈8.9 sq. ft. footprint) | All-weather resin, wood-look texture | Weatherproof resin, lockable lid, seats up to 551 lbs. |
| Keter Signature Vertical Storage Shed | $754.99 | 50 cu. ft. | 55.1″W x 29″D x 67″H (≈11.0 sq. ft. footprint) | Resin reinforced with steel, double-wall panels | Fully enclosed shed, lockable double doors |
How to Decide Which One You Actually Need
Before comparing prices, take stock of what you’re actually trying to clear off the patio and how much floor space you’re willing to give up to do it. If the pile is mostly soft goods — cushions, throw pillows, a couple of pool towels — a deck box or bench will handle it. If you’re also trying to fit rigid, bulky gear like a folded wagon, rakes and shovels, or a full set of yard games, that’s the point where a small shed starts to make more sense than stacking two boxes side by side.
Footprint matters as much as capacity on a small patio. A deck box and a storage bench both sit low and wide, eating floor space you might want for actual seating or a grill. A vertical shed trades some of that same footprint for a lot more height, which is why it returns more cubic feet per square foot even though it costs more. If your patio is already tight, that vertical trade-off is worth the extra cost; if you have a spare corner of yard instead, the shed’s larger footprint stops being a real constraint.
Suncast 134-Gallon Deck Box: Best Budget Pick
The Suncast 134-gallon deck box (model BMDB134004, sold in a Java Brown wicker-look finish) is currently listed at $189.00 through Home Depot, with exterior dimensions of 55 inches wide, 28.5 inches deep, and 27 inches tall. At roughly 17.9 cubic feet of rated capacity, it’s simply the most volume you can buy for the least money in this comparison — nothing else here comes close on cost per cubic foot. It’s also the box we’d point you to for bulky, irregular items that don’t fold flat: a spare fire pit cover, a coiled hose, extra cushions from a second seating set.
- Pros: Lowest price and lowest cost per cubic foot of the three; wide, boxy interior handles oddly shaped items well; resin shell needs no maintenance.
- Cons: Suncast doesn’t publish interior dimensions separately from exterior, so wall thickness eats into usable space by an unknown margin; it’s a container first, with none of the seat-cushion engineering the bench has.
Named dealbreaker: if you plan to actually sit on it regularly, don’t — Suncast doesn’t rate this model’s lid for repeated seating the way the Keter bench’s lid is engineered, and owners on retail listings consistently describe it as “storage that you can perch on occasionally,” not furniture.
Keter Solana 70-Gallon Storage Bench: Best Overall Pick
The Keter Solana is listed on Walmart at $199.99 (Grey) or $200.34 (Brown), carrying a 4-out-of-5-star average across 41 customer reviews at the time of research. Exterior dimensions run 54.6 inches long by 23.4 inches wide by 32.8 inches tall, with a published interior cavity of 50.4 x 19.7 x 15 inches and roughly 70 gallons (≈9.4 cubic feet) of capacity. It’s rated to seat up to 551 pounds, which is the entire reason to pick it over a plain box: this is the only product in the comparison that’s genuinely designed to double as patio furniture rather than storage you happen to sit on.
That said, it comes at a real premium — at roughly $21.37 per cubic foot, it’s the most expensive way to buy storage volume of the three, because part of what you’re paying for is the reinforced, contoured seat rather than raw cubic feet.
- Pros: Doubles as real seating rated to 551 lbs.; lockable lid; well-reviewed on retail listings; wood-look resin blends into most patio setups.
- Cons: Highest cost per cubic foot of the three; narrower interior than either the deck box or the shed; smaller total capacity than both alternatives.
Named dealbreaker: the interior is only 19.7 inches wide. A standard 24-inch-square patio chair cushion will not lie flat inside — it has to go in on its side, which wastes space and can crease foam padding over time. If flat-stacking full-size chair cushions is your main goal, the deck box’s wider interior is the better fit; save the Solana for pool toys, throw pillows, garden tools, and gear that doesn’t mind sitting on edge.
Keter Signature Vertical Storage Shed: Best Upgrade Pick
The Keter Signature Vertical Storage Shed (Storm Grey) lists directly through Keter.com at $754.99. Exterior dimensions are 55.1 inches wide, 29 inches deep, and 67 inches tall, with a published interior of 51.4 x 26 x 64.7 inches and a rated 50 cubic feet of capacity — a footprint of 4.6 x 2.4 feet, or about 11 square feet of patio real estate. Construction is resin reinforced with steel and double-wall panels, finished in a DecoCoat wood-look texture, with lockable double doors sealing the whole cavity.
This is the pick for anyone who has already maxed out a deck box or bench and needs to store bulkier gear standing upright — a folded beach wagon, a full cornhole set, rakes and shovels leaned upright, or a full patio cushion set plus everything else. Because it’s tall rather than wide, it delivers far more storage per square foot of yard it occupies than either the box or the bench.
- Pros: By far the largest capacity (50 cu. ft.); highest storage density per square foot of footprint of the three; fully enclosed and lockable, not just a lidded box; steel-reinforced double walls.
- Cons: Roughly 4x the price of the deck box; needs a genuine dedicated footprint rather than tucking against existing furniture; assembly is a bigger project than either of the other two.
Named dealbreaker: at $754.99 and nearly 11 square feet of permanent floor space, this isn’t a casual add — you’re committing real patio or side-yard real estate and a heavier assembly job. If you’re not sure you need more than a deck box’s worth of room, don’t buy the shed “to be safe”; upsize only once you’ve actually run out of room in a box or bench.
What You’re Really Paying Per Cubic Foot of Outdoor Storage
Sticker price alone is misleading here, since the three products hold very different amounts of stuff. We converted each manufacturer’s rated capacity to cubic feet (1 gallon = 0.1337 cubic feet) and divided the current price by that figure to get a real cost per cubic foot. We also divided capacity by footprint to see how much volume each option returns per square foot of patio or yard it occupies — call it storage density.
| Product | Price | Capacity (cu. ft.) | Cost per Cu. Ft. | Footprint (sq. ft.) | Storage Density (cu. ft. per sq. ft.) |
|---|---|---|---|---|---|
| Suncast Deck Box | $189.00 | 17.9 | $10.55 | 10.9 | 1.64 |
| Keter Solana Bench | $199.99 | 9.4 | $21.37 | 8.9 | 1.05 |
| Keter Vertical Shed | $754.99 | 50.0 | $15.10 | 11.0 | 4.53 |
Three things fall out of that table. The deck box is the cheapest way to buy raw volume, at $10.55 per cubic foot. The bench is the most expensive per cubic foot at $21.37 — you’re paying a premium for the reinforced seat, not the storage. And the shed, despite costing four times as much upfront, is by far the most space-efficient: at 4.53 cubic feet of capacity per square foot of footprint, it returns nearly three times the density of the deck box and more than four times that of the bench, because it grows vertically instead of eating patio floor space.
What Actually Fits Inside Each One
Cubic feet are abstract until you translate them into the stuff you’re actually trying to clear off the patio. Using a standard 24 x 24 x 5-inch outdoor seat cushion (about 1.67 cubic feet each) and assuming roughly 65% stacking efficiency — accounting for lids, hinges, and the fact that cushions don’t stack as neatly as blocks — here’s a rough planning estimate for each option.
| Product | Capacity (cu. ft.) | Est. 24-in. Cushions* | Reality Check |
|---|---|---|---|
| Suncast Deck Box | 17.9 | ~7 | Interior width comfortably fits full 24-in. cushions flat, with room to spare for a coiled hose or fire pit cover. |
| Keter Solana Bench | 9.4 | ~3–4, on edge only | The 19.7-in. interior width is too narrow for 24-in. cushions to lie flat — plan on smaller or thinner items instead. |
| Keter Vertical Shed | 50.0 | ~19–20 | Enough room for a full cushion set plus upright items like a folded beach wagon or a cornhole set. |
*Estimate assumes standard 24 x 24 x 5-inch outdoor seat cushions and roughly 65% stacking efficiency. Treat this as a planning guide, not a guarantee — actual fit depends on cushion shape, thickness, and what else you’re storing alongside them.
How We Compared
We did not physically test these three products side by side. Every spec in this comparison — price, dimensions, capacity, and material — comes from each manufacturer’s own product page and current retail listing (Home Depot, Walmart, and Keter.com), checked at the time of publication. Where we reference reliability or comfort patterns, such as the Solana bench’s 4-out-of-5-star average across 41 Walmart customer reviews, that reflects owner feedback aggregated on the retail listing itself, not our own hands-on use.
A few owner-reported patterns worth flagging: resin lid hinges in this price range commonly get called out for needing occasional silicone lubrication after a season of sun exposure, and multi-wall shed panels consistently draw better marks for wind resistance than single-wall bins of similar height. None of that replaces your own judgment about your climate and how hard you’ll use these products.

Frequently Asked Questions
How many gallons of outdoor storage do I actually need?
For a single patio set’s worth of cushions and covers, 70 to 100 gallons is usually plenty. Add roughly 30 to 50 gallons per additional furniture set, and move up to a small shed’s cubic-foot range once you’re storing bulky items like a folded beach wagon, a cornhole set, or lawn tools.
Is a deck box or a storage bench better for patio cushions?
A deck box like the Suncast 134-gallon holds more cushions for less money because its wider interior lets standard 24-inch cushions lie flat. A narrower option like the Keter Solana bench trades some of that flat-stacking room for a usable seat.
Do small resin storage sheds need a permit?
Most municipalities exempt small sheds under roughly 100 to 120 square feet of footprint from permitting, and a shed with an 11-square-foot footprint like the Keter Signature Vertical is well under that threshold almost everywhere. Zoning rules and HOA covenants vary, so confirm with your local building department before installing one.
Can resin deck boxes and sheds be left outside all year?
Yes — all three products here are built from weather-resistant resin rated for year-round outdoor exposure, though owners in snow-heavy climates commonly report clearing accumulated snow off flat lids so it doesn’t stress the hinges.
What’s the difference between a deck box and a storage bench?
A deck box is a plain lidded container optimized purely for interior volume, while a storage bench is engineered with a reinforced, contoured lid built to be sat on regularly. You’re usually paying a premium per cubic foot for that seating function.
How much does outdoor storage cost per cubic foot?
Among the three products compared here, cost per cubic foot ranged from about $10.55 for the deck box up to $21.37 for the storage bench, with the small shed landing in between at roughly $15.10 per cubic foot.
Whatever you land on, matching the box to the mess is more useful than chasing the biggest number on the label — a deck box that swallows your fire pit cover and hose for $189 solves a real problem for a lot less than a shed does, and a shed that sits half-empty for a year is just an expensive lawn ornament.
