Frequently Asked Questions

As of January 2026 and based on a typical 4 person sauna heated by an 8kw electric heater, a per hour cost is likely less than the cost of a coffee. It will obviously depend on your energy tariff, but somewhere around £3-£4 for the first hour to heat the sauna, then significantly less per hour after that as the heat capacity of the sauna stones coupled with the insulation ensure the sauna needs very little energy to remain warm.

No. A sauna can be built in the garden under permitted development, as long as you adhere to the more than generous constraints. Refer to your local planning portal, or AI to see the guidelines.

Not a lot, but it all depends on your specific needs. As an optimum size, imagine a cube measuring 2.4m x 2.4m x 2.4m; this would be ample for a 4-5 person sauna heated from an 8kw heater.

Both – but it’s all down to personal preference and constraints. I would recommend electric as it is more convenient to heat and doesn’t create smoke that may not be permitted in your area, or potentially upset your neighbours!

Somewhere around 4 weeks from ground works to your first home sauna. This depends on factors such as weather conditions and size / complexity of the build.

A 30-minute sauna session profoundly impacts the body by simulating moderate-intensity exercise, inducing deep muscle relaxation, and triggering intense sweating. It boosts cardiovascular function by increasing heart rate and lowering blood pressure, improves circulation, reduces inflammation, and relieves stress, leaving users feeling both relaxed and energized. 

For most people, a safe and effective sauna session lasts between 15 and 20 minutes, repeated over 2 to 3 sessions with a cold plunge to reset in between. Beginners should start with shorter sessions of 5–10 minutes to allow the body to acclimate. Always listen to your body, stay hydrated, and exit immediately if you feel dizzy, lightheaded, or uncomfortable

The price will vary depending on your requirements. As a rough guide, a basic ‘sweatbox’ design measuring 2.4m cubed with appropriate quality timbers, full insulation & vapour guard, EPDM rubber roofing, 8KW electric heater with stones, floating internal walls and bespoke bench joinery would be somewhere in the region of £12,000 (excluding electricians connection costs and cold dip). Even this ‘basic’ build is far higher quality than any off-the-shelf solution online – and likely less than half the cost of comparable products!
