How to choose a garden storage box
A garden storage box does a shed's job on a smaller footprint. It keeps cushions, tools, toys and barbecue kit dry beside the patio. This range covers 16 boxes in two materials: plastic and powder-coated steel. Match the box to what you store and where it sits. Need more room? See our garden storage and plastic sheds. For frames, the bike storage range locks bikes away. For bigger loads, try metal sheds or tool sheds.
Plastic boxes are the popular choice. They never rust, never need painting and wipe clean in seconds. Metal deck boxes trade a little weight for extra security. Both come with weatherproof seals and lockable lids as standard.
When we fit a box, we stand it on a hard, level surface. We leave a finger-width gap behind it against the wall. That stops damp building up and keeps the lid opening cleanly. A box straight on soil traps water underneath within a season.
Plastic vs metal storage boxes

|---|---|---|
| Maintenance | None, wipe clean | None, powder-coated |
| Rust | Never rusts | Rust-resistant coating |
| Security | Padlockable lid | Padlockable, heavier lid |
| Weight empty | Light, easy to move | Heavier, stays put |
| Best for | Cushions, tools, toys | Cushions plus extra security |
Matt's pick
For most gardens we point people at the Lifetime 568 Litre box at £159. It swallows a full set of rattan cushions. The lid is strong enough to sit on. The double-wall plastic holds its shape in July heat. The 439 Litre version at £144 suits smaller patios.
What size do I need?
Capacity is measured in litres. As a rough guide, 300 litres holds a two-seat set of cushions. 440 litres takes a three-seater. 550 litres and up covers a corner sofa, or a mix of cushions and tools. Measure the space first. Lids need clearance to open fully.
Where to put it
Stand the box on paving, decking or a hard, level base. Avoid bare soil, which traps damp under the floor. Leave a small gap behind the box so the lid clears the wall. A sheltered spot near the back door keeps cushions handy.
What will it cost?
Plastic boxes in this range start at £144. Larger metal deck boxes cost more for the extra security and capacity. Every box includes free mainland delivery. The price you see is the price you pay.
Garden storage box questions
Are plastic garden storage boxes waterproof?
Yes, the lids are weather-sealed to keep rain out. Contents stay dry through a British winter. Stand the box on a level base so water cannot pool underneath.
Can you lock a garden storage box?
Yes, every box takes a padlock. The lid has a hasp or lugs for one. Padlocks are not included, so add one to size.
What can I keep in a garden storage box?
Cushions, tools, toys and barbecue kit are the usual load. Keep petrol tools and chemicals in a ventilated shed instead. The sealed lid keeps everything else dry.
Do storage boxes need a base?
They need a hard, level surface, not a full base. Paving, decking or concrete all work. Avoid bare soil, which holds damp under the box.
Is plastic or metal better for a storage box?
Plastic is lighter and never rusts, so it suits most gardens. Metal gives a firmer lid and extra security. Both are maintenance-free.
How long do plastic storage boxes last?
A good plastic box lasts many years outdoors. The double-wall types resist fading and cracking. UV-stable plastic keeps its colour far longer than cheap single-skin boxes.
