200 Gallon Extra Large Deck Box - Spacious Lockable Outdoor Storage

Our review of the 200 Gallon Extra Large Deck Box finds it best suited for homeowners who need a single, weatherproof solution for bulky patio cushions, pool supplies and garden tools; its single biggest selling point is the sheer capacity combined with a sturdy double-wall resin build that also serves as extra seating. The box ships in two packages, so buyers should expect staggered delivery, and assembly takes about 30 minutes with two people being helpful for aligning panels and securing fasteners.

Key Features

• 200 gallon capacity: The large interior easily stores multiple patio cushions, pool toys and more, reducing clutter on decks and patios.
• Double-wall construction: A dual wall resin structure improves durability and resists the elements while keeping stored items dry.
• Flexible divider: The built-in divider and two adjustable slots allow for custom partitions or full open storage when a single large space is needed.
• Multiuse surface: The top doubles as a bench or extra table and supports up to 990 lbs, making it useful as seating for gatherings.
• Lockable design: The lid accepts a padlock for added security and peace of mind when storing tools or pool supplies.
• Wood-texture finish: All-weather guard resin with a wooden texture blends with outdoor furniture without the maintenance of real wood.

Who It's For

This deck box is ideal for families with large cushions, bulky backyard items or seasonal gear who want a single roomy storage unit that also functions as occasional seating. It fits well on patios, by pools or on larger decks where the 55.3 in by 28.3 in footprint and 33.5 in height can be accommodated.

It is less appropriate for buyers who need immediate single-package delivery or those with very tight assembly tolerance who must complete setup solo; some customers report assembly is easier with a partner and parts arrive in two boxes that may not be simultaneous.
