Keter vs ATMELT Deck Boxes: Storage, Lid and Build
As an Amazon Associate we earn from qualifying purchases. Details
Keter and ATMELT both sell resin outdoor storage boxes, but they sit at opposite ends of the size range in this comparison. A 30-gallon Keter City box and a 160-gallon ATMELT chest are different purchases, even though both can serve as seating. This page sets the stated dimensions, capacities, closures, and build notes side by side. Figures come from listing data checked on 2026-10-12 for the two research products and on 2026-10-20 for the two extra Keter listings.
Quick answer
If the box has to fit a balcony corner or a narrow patio, the Keter City 30-gallon box has the smallest stated footprint of the four listings here, at 22.75 by 17.3 inches. If storage volume is the main need, the ATMELT listing states 160 gallons of capacity, although its own specification table also gives 180 gallons as storage volume. Keter’s listed capacities in this set run from 30 gallons up to 110 gallons, so the choice between the two brands depends mostly on how much space the box has to occupy.

Keter City 30-gallon outdoor storage box
The listing states exterior dimensions of 22.75 by 17.3 by 21.7 inches and an interior of 22.71 by 16.3 by 20.3 inches, according to a bullet. Capacity is 30 gallons, the material is resin, the color is dark grey, and the style is graphite. The item weighs 7.9 pounds and the listing gives a maximum weight recommendation of 220 pounds. The flip-top lid opens on a hinge, and the box has a built-in handle.
The listing says assembly needs no extra tools and that the panels click together. Its bullets describe a wood-look texture and state that the polypropylene resin will not rust, peel, or dent. Special features listed include lockable, impact resistant, and UV resistant. The manufacturer warranty is two years, limited. The listing names outdoor storage as the recommended use and mentions cushions, garden tools, pool essentials, and bird seed among the contents.
ATMELT 160-gallon waterproof resin deck box
The ATMELT listing states a capacity of 160 gallons and a storage volume of 180 gallons, and both figures appear in its specification table. Exterior dimensions are 50.85 by 22.24 by 25.69 inches. The material is polypropylene, the color is black, and the style is listed as contemporary. The special features are airtight, dustproof, fireproof, shatterproof, and weathertight, and the closure is interlocking with a snap opening mechanism.
The title mentions a support rod, but the bullets do not describe one, so buyers should check the product page for what is included. The bullets describe a bench that doubles as seating, a woven rattan-style surface, and snap-on panels that the listing says need no complex tools. The listing describes the resin as one that will not rust, dent, or peel. No weight and no maximum load are given in the data used for this page.
Keter Kentwood 50-gallon storage box
The Kentwood listing states exterior dimensions of 32 by 17.5 by 22.75 inches and a capacity of 50 gallons. The color is dark grey, the material is resin, and the style is garden. The shape is rectangular. Bullets describe the box as suited to balconies, patios, porches, and garage areas, and list patio cushions, pool accessories, and beach towels as typical contents.
The listing says the all-weather resin resists rust, peeling, fading, and denting. It also says the box is sturdy enough to double as extra outdoor seating in a small space. No weight, closure type, or water resistance level is stated in the data used here, so those points remain open for this product.
Keter Borneo 110-gallon deck box
The Borneo listing states exterior dimensions of 51 by 24.6 by 27.6 inches and a capacity of 110 gallons. The color is grey and the pattern is described as rattan wicker resin. The shape is rectangular. The listing says hydraulic pistons give an easy-lift, soft-close action on the lid.
The bullets name patio furniture, outdoor cushions, garden tools, and pool toys as contents, and say the box doubles as outdoor bench seating. The listing gives no weight and does not say whether the lid locks.
How these listings were chosen
The research set for this keyword held two products: the Keter City and the ATMELT box. Two extra Keter listings were added from checks dated 2026-10-20, so the Keter line could be shown at its larger sizes. All four listings are kept because each one has a stated capacity and exterior size. Where a title and a specification table disagree, both values are printed above, including the ATMELT 160 and 180 gallon pair.
Worked example: footprint and capacity per listing
Using only the exterior dimensions in the listings, the Keter City footprint is 22.75 times 17.3, which is about 394 square inches. The ATMELT footprint is 50.85 times 22.24, which is about 1,131 square inches. That makes the ATMELT box about 2.9 times as large on the floor. Its stated capacity of 160 gallons is 5.3 times the 30 gallons of the Keter City, and against the 180-gallon storage volume the ratio is 6 times.
The Borneo footprint is about 1,255 square inches, which is roughly 11 percent larger than the ATMELT footprint. Its listed height of 27.6 inches is also the tallest in the set, about 1.9 inches above the ATMELT’s 25.69. A buyer comparing these two should measure the clear space needed to lift the lid, not only the floor area, because the listings describe lid types that open in different ways.
What the listings do not say
Weight is missing for the ATMELT, Kentwood, and Borneo listings, so their handling and placement cannot be judged from the data on this page. The ATMELT listing states a fireproof finish, but it does not give a test standard or a rating. The 160-gallon and 180-gallon figures for the ATMELT conflict within the same listing. The title’s support rod is not described in the bullets. None of the listings gives a maximum seating load except the Keter City, which gives 220 pounds for its maximum weight recommendation.

Conclusion
For a small outdoor space with a firm footprint limit, the Keter City 30-gallon box fits the stated numbers most closely. For a large volume of cushions, tools, or pool gear, the ATMELT and Keter Borneo listings state much higher capacities, but both need a clear measurement of the lid swing and the floor area before purchase. Confirm the weight and closure details on each product page, since this page could not confirm them from the listings.
