Saunas are not expensive to run, but the amount of heat they produce can be costly. A traditional Finnish sauna produces heat levels of around 190-210 degrees F, while a modern infrared sauna can produce heat levels of up to 140 degrees F. The cost of running a sauna will depend on the type you have, your local energy rates, and how often you use it. But as a general rule, expect to spend between $0.50 and $1 per hour to operate a standard sauna, and between $0.25 and $0.50 per hour to operate an infrared sauna.

It depends on the sauna. Infrared saunas, for example, use about the same amount of electricity as a light bulb. Other types of saunas may use more or less electricity, depending on their size and features. The cost to run a sauna is typically very low – much lower than the cost to run a hot tub or Jacuzzi. In fact, many people find that they can heat their home with a sauna by using it as an auxiliary heating system.
