100 Gallon Waterproof Resin Deck Box - Large Lockable Outdoor Storage

Our review of this 100 gallon resin deck box finds it best for homeowners who need a weatherproof, attractive place to stash bulky cushions and garden tools. The single biggest reason to buy is the combination of large capacity and durable poly resin construction that resists fading and water, so outdoor items stay dry and the box keeps looking neat. Assembly is straightforward and the rattan pattern gives a modern look that fits on a patio or poolside while the lockable lid and soft-opening gas rods add useful security and safe handling.

Key Features

• Chic rattan design: The wicker-style pattern provides a clean, modern look that complements a variety of outdoor settings and hides stored items from view.
• 100 gallon capacity: With internal space sized to hold multiple chair cushions, pillows or long-handled tools, it reduces clutter on decks and porches.
• Weather-resistant poly resin: The waterproof material prevents rusting and peeling so the box can stay outdoors season after season with minimal maintenance.
• Dual gas rods: Gas-assisted lid opening and slow closing prevent sudden slams and reduce the risk of pinched fingers when accessing contents.
• Bench seating for two: The lid supports up to 500 lbs, making it usable as extra seating while keeping storage discreet.
• Lockable lid: A simple lock point helps secure belongings against casual access and keeps the lid closed in wind.

Who It's For

This deck box is ideal for families and couples who need a low-maintenance outdoor storage solution that doubles as seating. It suits people who store bulky soft items like chair cushions, pool towels and throw pillows, or garden tools that fit the roughly 48 in by 21 in footprint.

It may not be the right choice for someone who needs a heavy-duty tool chest for sharp metal tools or very large items that exceed the 100 gallon interior. Also, buyers seeking all-metal construction for extreme durability should look elsewhere.

Pros & Cons

Cons

• Some users report occasional lid alignment issues that affect how neatly it closes.
