Outdoor Resin Deck Boxes: 2 Picks Compared
As an Amazon Associate we earn from qualifying purchases.
The deck boxes Keter vs NUNU LAB search compares two outdoor resin storage boxes that are very different in size. The research set holds only these two products, so the title names the product type rather than the brands, and every figure below is taken from the listing data.
The listings were checked on 2026-10-12. Where one listing gives two values for the same field, both values are shown, because a mismatch between fields is the first thing to check before buying a deck box.
Quick answer
Choose the Keter if a small box for cushions and tools on a patio is the goal, since its listed capacity is 30 gallons and it weighs 7.9 pounds empty. Choose the NUNU LAB if a much larger lockable box is needed and the extra weight is acceptable, since its listed capacity is 160 gallons and its empty weight is 27.2 pounds. The water resistance wording differs between the two NUNU LAB fields, so check that before relying on it outdoors.

Keter City 30 gallon outdoor storage box
The listing states 30 gallons of storage in a dark grey resin box with a wood-look texture. Its exterior is 22.75 inches long, 17.3 inches wide and 21.7 inches high, and a bullet gives the interior as 22.71 by 16.3 by 20.3 inches. The title also names it as a patio side table, but no separate table dimension is given. The bullets describe weather-resistant polypropylene that the listing says will not rust, peel or dent.
NUNU LAB 160 gallon lockable deck box
The listing gives 160 gallons of storage in a black resin box measuring 47.8 by 21.3 by 24.4 inches outside, with a listed empty weight of 27.2 pounds. It has dual side handles, a soft-close lid and a lock. The specification field says Water Resistant, while a bullet says it is fully waterproof and UV-protected, so the two wording choices do not match. The listing gives no interior dimensions and no maximum weight recommendation for the lid.
How the two boxes were compared
Both listings are for outdoor resin storage boxes with a flip top, and both are offered as lockable. The comparison uses the stated capacity, the exterior and interior sizes, the empty weight and the stated water resistance. Storage use examples in the listings include cushions, pool floats, garden tools and seasonal items, and those are the only uses the comparison is based on.
Worked example: capacity against the listed size
The Keter interior is 22.71 by 16.3 by 20.3 inches. That volume is about 7,514 cubic inches, or about 32.5 US gallons at 231 cubic inches per gallon. The listing states 30 gallons, so the stated figure is a little below the volume the interior measurements imply. The gap is small, but it shows that the stated capacity is a nominal figure.
The NUNU LAB exterior is 47.8 by 21.3 by 24.4 inches, about 24,842 cubic inches or about 107.5 gallons of outside envelope. The listing states 160 gallons. Because the interior size is not given, the 160 gallon figure cannot be reproduced from the listing dimensions, and the box should be measured inside before a large item is planned around it.
What the listings do not say
- The NUNU LAB listing gives no interior size and no lid load limit.
- The Keter listing gives a maximum weight recommendation of 220 pounds, which the NUNU LAB listing does not state.
- The Keter excerpt in the research file does not mention UV resistance, while the NUNU LAB bullets do.
- The NUNU LAB title says gas lift, but the listing gives no lid support rating or hold-open force.

Frequently asked questions
Which deck box has the larger listed capacity?
The NUNU LAB listing states 160 gallons, and the Keter listing states 30 gallons. The NUNU LAB figure is about 5.3 times the Keter figure, but the NUNU LAB interior is not measured in the listing.
Is the NUNU LAB box waterproof?
The listing gives two statements. The specification field says Water Resistant, and a bullet says fully waterproof. Confirm which wording applies on the product page before storing electronics or fabric outdoors.
Can both boxes be locked?
Both listings say they are lockable. The Keter lists lockable among its special features, and the NUNU LAB lists a lockable lid with its handles.
Which box is heavier when empty?
The NUNU LAB weighs 27.2 pounds, while the Keter weighs 7.9 pounds. The heavier box is also the larger one, so lifting it into place may need two people.
Bottom line
For a deck box, the choice depends on the volume needed. The Keter fits a 30 gallon load and weighs much less. The NUNU LAB holds far more on its listed figure, but its interior size and water resistance wording need checking before purchase.
