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.
How hot do the saunas get?
- Traditional steam saunas: 18–99°C, set via the control panel (0–90 mins).

When should I add water to the stones?
Only add water once the stones are fully heated. Adding water too soon reduces steam quality and may damage the heater.
How do I know when the stones are hot enough?
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.
