Best Shed for a Home Gym UK (Under Heavy Use)

Quick answer: For a garage-gym kit, start with a thicker shed like the BillyOh Pro Pent HD 8x6. The Waltons 8x6 is the budget runner-up. Neither replaces a proper floor — rubber tiles + joist check before plates and racks.

UK buying reality

Honest UK caveats: (1) power is almost never included — budget a qualified electrician for an outdoor RCD-protected circuit; (2) damp/condensation kills electronics and rusts iron — plan a vapour barrier, dehumidifier, and ventilation; (3) size labels (8x6, 10x8) are external — measure internal floor before desk or rack layouts; (4) security matters for kits — upgrade locks/hasp; (5) planning — many small outbuildings sit under permitted development, but height, eaves, listed settings, and “garden office” use can push you into needing permission. Check your local authority; we are not planners. Gym kits add point loads — verify floor board thickness and base (concrete/paving) before buying a rack.
