Trimetals Stowaway (Medium) Garden Storage Box

The Trimetals Stowaway (Medium) is a compact, high‑quality metal garden storage box designed to keep tools, toys, cushions, and outdoor equipment safe, dry, and neatly organised. 

Manufactured in the UK from PVC‑coated galvanised steel, it offers exceptional durability with zero maintenance, no painting, rotting, or warping.

Its clever low‑profile design makes it ideal for smaller gardens, patios, balconies, and tight spaces where traditional sheds won’t fit. The wide, spring‑assisted up‑and‑over door provides full‑width access, making it easy to load and remove items without awkward lifting.

Backed by a 25‑year panel guarantee and endorsed by the Royal Horticultural Society (RHS), the Stowaway is a long‑lasting, reliable storage solution built to withstand the British climate.
