Outdoor Storage Boxes

Outdoor storage box buying guide

Types & styles of outdoor storage boxes

At Trade Tested, we stock outdoor storage boxes in these popular styles:

Deck and patio storage boxes: Ideal for cushions, outdoor throws, pool toys, and BBQ accessories.

Garden and shed-style storage boxes: Store mowers, long-handled tools, BBQs, pool pumps, bikes, or wheelie bins. Front-opening doors, sloped thresholds, and floor panels make it easy to wheel items in and out.

Bench-style storage boxes: With high lid load ratings, these boxes provide dry storage underneath and extra seating on top. Perfect near the pool, on the deck, or anywhere guests tend to gather.

Colour & design options for your outdoor space

You’ll find outdoor storage bin sizes ranging from 113L to 1200L, providing enough room for all the loose items you need to store. Compact boxes suit balconies and smaller patios where space is limited, while bench-style boxes provide storage and seating in gardens. Shed-style outdoor storage boxes are also suitable for larger outdoor spaces, where they efficiently conceal gardening tools, bikes, and rubbish bins.

Keter garden storage boxes feature neutral charcoal finishes and wood-look styles that sit comfortably alongside timber decking, concrete patios, and modern outdoor furniture. DUOTECH™ outdoor waterproof storage boxes can be painted, allowing you to match fencing and decor.

Fit, placement & care tips

Before choosing a size, measure the available space and what you plan to store. Allowing a bit of clearance around lids and doors makes day-to-day access easier and avoids awkward opening angles.

Once assembled, place your storage box on level ground so lids close neatly and gas struts operate smoothly. While Keter boxes are UV-stabilised, positioning them in partial shade can help maintain their finish over time.

To keep your waterproof box in tip-top shape, give it an occasional wipe-down with a damp cloth. From time to time, check hinges and pistons to ensure everything continues to open and close as it should.

What our customers say

Keter Darwin Storage Box 570L

“Awesome for all storage. We have recently bought 4 of these storage boxes after downsizing our home and needing good waterproof outdoor storage. These boxes are very easy to assemble and are very strong and sturdy, and keep everything dry. Eg: firewood, outdoor furniture, golf clubs etc... Solved all our storage issues.”

Keter Ontario Outdoor Storage Box 870L

“I needed a strong and resilient outdoor storage box to accommodate enough firewood for a New Zealand winter. This box is relatively easy to assemble and able to hold enough wood to meet my needs. It is a superb outdoor storage box to keep the firewood dry throughout the winter months. I love it!!”

Keter Denali Duotech Outdoor Deck Box 113L

“This is the second one we've bought. One is on our front porch for shoe storage, and the second in my outdoor bath area. Great weatherproof box to keep lounger cushions and bath gear. Also doubles as a table while we're relaxing in this space. Easy to put together. Definitely would recommend.”
