Sauna Installation & Planning

Most of the regret around sauna ownership traces back to the planning stage. Wrong size for the space. Wrong heater for the build. No 32A circuit and a sparky needed at short notice. Foundations that look fine until the first winter. Permitted-development assumptions that turn out to be wrong.

These guides cover the UK-specific practical side: planning permission rules in England and Wales, what your electrician needs to know before they price the install, expected running costs at current UK electricity rates, and what to budget for the bits the manufacturer brochure skips.

When you’re ready to talk to someone, our UK builder directory connects you with vetted installers in your region — most can quote remotely on standard cabins and visit for custom builds.
