Best Outdoor Storage Boxes

How to Choose an Outdoor Storage Box

Outdoor clutter disappears when you give it a home. Storage boxes keep cushions dry, toys organized, and garden tools accessible. The right box blends into your patio while holding everything you need to hide.

Capacity Guide

Under 50 gallons: Small items—hose accessories, gardening gloves, pool chemicals
50-99 gallons: Pool toys, a few cushions, BBQ accessories
100-150 gallons: Full cushion sets, multiple floats, seasonal storage
150+ gallons: Everything—cushions, toys, garden tools, decorations

Measure your cushions before buying. A "large" storage box that can't fit your seat cushions flat is frustrating.

### Material Options

Resin/Polypropylene: The standard. Weather-resistant, no maintenance, won't rot or rust. Can get brittle over years of sun exposure.

HDPE (High-Density Polyethylene): Premium plastic. More durable than standard resin, better UV resistance, higher price.

Wood: Traditional look, but requires maintenance (sealing, staining). Cedar and teak resist rot naturally. Beautiful but demanding.

Metal: Durable but can rust (unless aluminum). Gets hot in sun. More common for sheds than deck boxes.

### Key Features

Lockable: Most boxes are padlock-compatible. Important if storing valuable items or keeping kids out of pool chemicals.

Piston/Spring lid: Makes opening easy with full hands. Standard lids can slam or blow shut.

Seating function: Many large boxes double as benches. Check weight capacity—most hold 2 adults comfortably.

Drainage: Bottom vents or drainage holes prevent standing water and musty smells.

### Weatherproofing Reality

"Weather-resistant" doesn't mean waterproof. Most deck boxes keep contents dry in rain, but extended exposure or heavy storms can allow moisture seepage. Condensation forms inside during temperature swings. For truly sensitive items, add a dehumidifier packet or don't rely solely on the box.
