This is a used 10ft GymBox for sale – a once-used shipping container that’s been professionally converted into a ready-to-use garden gym. It comes lined, insulated, wired, and finished, so all you need is a level base and an external power supply to hook up and start training. If you’ve been looking for a compact home gym that doesn’t require planning permission, builders, or months of waiting, a 10ft GymBox is one of the quickest routes from purchase to first session.
What’s Included
This 10ft GymBox comes with a standard specification that covers the essentials for a functional, weatherproof, year-round training space:
The exterior has been repainted in a standard RAL colour, so it arrives looking clean rather than like a retired shipping container. Two-pane white French doors are fitted in the side panel, giving wide access for moving equipment in and out and letting natural light and airflow into the space – a significant upgrade over training behind a solid steel container door.
Inside, the walls are lined and insulated with 18 mm redwood timber, with 12 mm on the ceiling. The battens behind the lining are marked, which means you can confidently screw racks, hooks, pull-up bars, TV mounts, or any wall-mounted equipment directly into the structural supports without guessing where they are. That’s a detail that matters – mounting heavy gym equipment to a wall needs solid fixing points, and marked battens take the risk out of it.
The floor is 27 mm varnished marine plywood – hardwearing, moisture resistant, and tough enough to handle dropped weights, heavy equipment, and the kind of daily punishment a gym floor takes. Marine ply is the standard choice for container conversions because it handles temperature swings and humidity without warping or delaminating.
Electrical Installation
The GymBox comes fully wired with an external hookup point, consumer unit, strip lighting, double sockets, and a wall-mounted heater. That means you’ve got power for lights, music, a fan, phone charging, and any mains-powered equipment from day one – and the wall heater takes the edge off in winter so the space is usable all year round. The external hookup connects to your domestic supply via a standard outdoor armoured cable run (installation of the cable from your house to the container would need to be arranged separately by a qualified electrician).
Size and Siting
At 10 ft long, this is the most compact GymBox option. It’s big enough for a focused training setup – a squat rack or power cage, a bench, a set of dumbbells, kettlebells, and some floor space for bodyweight work and stretching. It won’t fit a full commercial gym’s worth of kit, but for a home gym where one or two people train at a time, 10 ft gives you a surprisingly usable space once it’s laid out efficiently.
The footprint is small enough to fit in most gardens, driveways, or yards. Shipping containers under a certain size typically fall within permitted development rights and don’t need planning permission in most cases, though this varies by local authority – always check with your council before siting a container on your property.
Delivery is usually by hiab (crane lorry), which lifts the container off the truck and places it directly onto your prepared base. You’ll need adequate access for the delivery vehicle and enough overhead clearance for the crane arm.
