10 Best Waterproof Outdoor Storage Boxes 2025 in the United States

The EAST OAK Outdoor Storage Box is a compact yet versatile option for those needing a waterproof storage solution for the outdoors. Made from durable, fade-resistant resin, it promises to protect your items from rain and sun exposure, which is great for garden tools, patio cushions, or pool gear. Its size (about 23 x 17 x 21 inches) offers 31 gallons of storage, enough for medium-sized items but may be small if you need to store larger equipment. A nice bonus is its sturdy top that can support up to 170 pounds, allowing you to use it as extra seating or a small table, adding practical value.

The locking mechanism is simple—a clip-on snap lock—providing basic security, though it might not deter a determined thief. Assembly is very easy, requiring no tools and only snapping panels together in under 10 minutes, making it user-friendly for anyone. The grey resin has a modern look that blends well outdoors without drawing too much attention. On the downside, while the box is portable with handles, its relatively light weight (around 8.4 pounds) means it could be moved or tipped over by strong wind or animals if not secured.

This storage box suits homeowners or renters looking for a waterproof, lockable container for small to medium outdoor items with added seating functionality, especially if you want quick setup and weather resistance without too much fuss.
