FAQ
How much does it cost to run a sauna?
Running costs depend on wattage and usage time. Our saunas range from 2kW to 10kW. On average, an hour’s use costs between £0.50 and £2.50. For more details, use an electricity cost calculator.
What warranties do you offer?
- Electrical components: 1 year
- Wooden parts: 2 years
Are the saunas easy to assemble/install?
Yes. All saunas include clear assembly instructions. Most panels are secured with buckles or clamps, with minimal screwing required. Infrared saunas plug into a standard household socket, while traditional steam saunas must be hardwired to the mains by a qualified electrician.

Only add water once the stones are fully heated. Adding water too soon reduces steam quality and may damage the heater.

The stones should feel intensely hot when you bring your hand close (without touching). Many heaters also have gauges – wait until it reads at least 300°F (approx. 150°C).
What type of water should I use?
Use clean, distilled water where possible. Tap water with high mineral content may cause limescale build-up over time.
