What is an outdoor sauna?
An outdoor sauna is a self-contained wooden sauna cabin designed for garden or external use. It’s built to handle UK weather conditions and provide year-round sauna sessions at home.
Are outdoor saunas weatherproof?
Yes. Outdoor saunas are constructed for external use, and the timber is treated at the factory before dispatch to help protect against moisture, UV exposure, and general weathering.
Do outdoor saunas need additional wood treatment?
No immediate treatment is required on delivery. Many owners choose to re-treat the exterior periodically to maintain appearance and extend the life of the timber.
Do outdoor saunas come with everything needed for assembly?
Yes. All outdoor saunas are supplied with everything required for assembly, including panels, fixings, benches, and heaters where applicable. No additional purchases are needed.
Do outdoor saunas need an electrician?
Some models plug into a standard UK socket, but higher-powered outdoor saunas require hardwiring into the mains. In those cases, a qualified electrician is needed for safe installation.
How much does an outdoor sauna cost to run in the UK?
Running costs depend on heater size, session length, and electricity tariff. Most outdoor saunas range from around 2000W to 8000W. A simple estimate is kW rating × hours used × unit rate (p/kWh).
Example: a 6kW sauna used for 1 hour at 30p/kWh costs about £1.80 per session.
Where can an outdoor sauna be installed?
Outdoor saunas should be installed on a flat, solid base such as paving or concrete. The area should be level, well drained, and accessible for delivery and assembly.
Do outdoor saunas need planning permission in the UK?
In many cases, outdoor saunas fall under permitted development, but this depends on size and location. It’s best to check local planning guidance if you’re unsure.
Can outdoor saunas be used all year round?
Yes. Outdoor saunas are designed for year-round use and are often especially enjoyable during colder months.
