As an Amazon Associate we earn from qualifying purchases. Details

The KAMABOKO box in this comparison is listed at 150 gallons, several times the size of the Keter City’s 30 gallons. That gap changes almost every other question, from floor space to the weight a person has to lift. This page compares the Keter City with the KAMABOKO and then sets the Keter Kentwood and a Devoko 78-gallon listing beside them. Research products were checked on 2026-10-12, and the extra listings on 2026-10-20.

Quick answer

For a large amount of storage, the KAMABOKO is the only listing in this set that states 150 gallons, and its bullets describe a bench rated for 680 pounds. For a small footprint, the Keter City stands out, with exterior dimensions of 22.75 by 17.3 inches and a stated weight of 7.9 pounds. The two sit at opposite ends of the set. The Keter Kentwood sits between them at 50 gallons, and the Devoko 78 falls between the Kentwood and the KAMABOKO in footprint.

Keter City 30-gallon outdoor storage box

The Keter City states 30 gallons of capacity and exterior dimensions of 22.75 by 17.3 by 21.7 inches. It weighs 7.9 pounds and carries a 220-pound maximum weight recommendation. The color is dark grey and the style is graphite. The lid is a flip top on a hinge, and the box has a built-in handle.

The bullets say assembly takes no extra tools and describe a resin that the listing says will not rust, peel, or dent. The manufacturer warranty is two years, limited. The listing names outdoor storage as the recommended use and gives cushions, garden tools, and pool essentials as examples of contents.

KAMABOKO 150-gallon resin storage box

The KAMABOKO listing states 150 gallons of capacity and exterior dimensions of 46.89 by 20.87 by 23.82 inches. The item weighs 22.4 pounds. The color is black, the material is resin, and the style is garden. The specification table lists a recycled material feature and recommends the box for tool storage. The lid closure is listed as a buckle.

The bullets add several details. They describe dual hydraulic gas struts that hold the lid open and a soft-close action. They state that the box can support up to 680 pounds as a bench, and that the top can serve as extra seating or a small outdoor table. Built-in side handles are mentioned, along with a lockable lid where the lock is not included. The listing describes a wood-grain look. Water resistance is a conflict: the specification table says water resistant, while the bullets call it a waterproof storage box.

Keter Kentwood 50-gallon storage box

The Kentwood listing states 50 gallons and exterior dimensions of 32 by 17.5 by 22.75 inches. It is dark grey, made of resin, and rectangular in shape. Bullets describe small outdoor spaces such as balconies, patios, porches, and garage areas, and list patio cushions, pool accessories, and beach towels as contents. The listing says the resin will not rust, peel, fade, or dent, and that the box doubles as seating.

No weight, closure type, or water resistance level is given in the data used for this page.

Devoko 78-gallon resin deck box

The Devoko title says 78 gallons while the specification table says 80 gallons. The exterior is 45.3 by 19.2 by 20.8 inches, and the color is black. The listing states a lockable feature. The bullets describe a rattan-like pattern, handles on both sides, a hydraulic hinge, and a use as both a deck box and a storage bench.

No weight is stated in the data used here, so this listing cannot be placed on the weight comparison.

How these listings were chosen

The research set for this keyword included the Keter City and the KAMABOKO. Two extra listings were added from checks dated 2026-10-20: the Keter Kentwood, which sits between the two research boxes in size, and the Devoko 78-gallon box, which shows a mid-size alternative. The KAMABOKO bullets say water resistant in one place and waterproof in another, and the specification table and bullets are both shown above rather than picking one.

Worked example: how much more the KAMABOKO takes up

Using only the exterior dimensions, the KAMABOKO footprint is 46.89 times 20.87, about 979 square inches. The Keter City footprint is about 394 square inches, so the KAMABOKO takes about 2.5 times the floor space. Its stated capacity of 150 gallons is 5 times the 30 gallons of the Keter City.

Weight shows a smaller ratio. The KAMABOKO’s 22.4 pounds is about 2.8 times the Keter City’s 7.9 pounds. Against the Kentwood, the KAMABOKO footprint is about 1.75 times as large, and the KAMABOKO is listed as 1.1 inches taller than the Kentwood at 23.82 inches against 22.75. The bench load on the KAMABOKO’s bullets is 680 pounds, compared with the Keter City’s 220-pound maximum weight recommendation, which is a different kind of figure and should be read as such.

What the listings do not say

The Kentwood listing gives no weight, closure, or water resistance. The Devoko listing gives no weight. The KAMABOKO’s water resistance and lid closure are described two ways within the same listing, and the 680-pound bench rating appears in the bullets only, not in the specification table. The lock is described as not included with the KAMABOKO, and no lock is described for the Keter City. Keter City’s warranty length is given at two years, but the KAMABOKO listing does not state a warranty length.
