Patio cushions, gardening tools, and everyday backyard clutter all need a weather-ready outdoor storage spot that keeps the deck tidy. Between two resin deck boxes on your short list, the main decision narrows to capacity, lid style, and price. Both boxes are waterproof and resin-built, so the practical differences come down to how much you want to store and how you'd like it to open.
Quick Verdict
The 45-Gallon Grey Deck Box is the better choice if you need more room and prefer a lockable, lift-off lid. The 31-Gallon Black Deck Box is the better choice if you want a more compact resin box and are comfortable working with a smaller footprint.

Product Notes
45-Gallon Grey Deck Box
This is the roomier box, with enough capacity for patio cushions, garden tools, and pool accessories. It can also double as a side table or yard seat, giving it a second job beyond storage. The lift-off lid can be locked with your own padlock, and the resin body is built to handle outdoor use. With its longer profile, it needs a deck or patio area with room to spare. If you want one storage box that can handle a bigger variety of backyard gear, this is the model to choose.
31-Gallon Black Deck Box
The 31-Gallon Black Deck Box is the more compact of the pair and fits into tighter deck corners. It still offers a practical amount of storage for gardening tools, smaller cushions, and everyday outdoor items. The flip-top lid gives you a direct opening style, and the resin construction is suited for outdoor exposure. It's a practical way to add outdoor storage without asking for much extra deck space. If your patio is short on square footage or you need a container for a modest amount of gear, this model is the streamlined choice.
Final Choice by Use Case
- Need to store larger patio cushions, pool accessories, or a mix of garden tools? Pick the 45-Gallon Grey Deck Box.
- Need a compact box for smaller outdoor gear? Pick the 31-Gallon Black Deck Box.
