FAQ's

How much does it cost to run a sauna?

The cost of running a sauna depends on its wattage and how long you use it. Our saunas typically range from 2kW to 10kW. On average, running a sauna for an hour can cost between ÂŁ0.50 and ÂŁ2.50. Please refer to this Electricity cost calculator for more information.

Are the Saunas easy to assembly/Install?

All our saunas come with Assembly Instructions which are easy and detailed. Saunas are assembled together using buckles/clamps with some screwing involved. For Infrared Light saunas, the sauna can be plugged into any standard outlet in the house. For traditional steam saunas, the power needs to be connected to the mains of the house by an electrician.

How hot does the sauna get and how hot does the steam get?

For traditional steam saunas, the heat time and temperature can set by control panel is: 0-90mins and 18-99 degrees Celsius. For Infrared Saunas, the maximum temperature is 65 degrees Celsius.

When is the right time to add water to the sauna stones?

To ensure optimal performance and to avoid potential damage, only add water once the sauna stones have reached the appropriate temperature. This heat level is necessary to properly vaporize the water, creating the ideal steam environment.

What size cable does this need for its supply?

For 3000W saunas, you would need at least 2.5mm size power input wire. For 4500W saunas, you would need at least 4mm power input wire.

Would an RCD be needed for the steam sauna?

Yes, a REC protection from the board would be needed. Please talk to your local electrician for details.

How long does it take to heat up once you turn it on?

When the external environment temperature is 10 degrees Celsius, it takes about 15 minutes to heat up to 50 degrees Celsius, and about 30 minutes to heat up to 70 degrees Celsius.

Does the timber from the outside get hot? Is it safe for children to touch this?

The timber outside is not hot, just little warmer and safety for touch.
