How Much Does It Cost to Run a Sauna?
Realistic running costs for electric outdoor saunas and wood fired stoves.
Running cost comes down to three things: the power of the heater, how long it runs and what you pay per unit of electricity.
An outdoor electric sauna with an 8 kW heater draws more while heating, typically 45 minutes to an hour, then cycles on and off to hold temperature. Most owners find a session lands somewhere between one and two pounds.
A wood fired stove removes electricity from the equation entirely. Your cost becomes firewood, and for many owners the fire is half the reason they chose it.
We can help you choose the heating option that best suits your garden, routine and preferred sauna experience.
