A traditional Finnish sauna usually runs between 70 and 110 °C. Throwing water on the stones briefly raises the humidity.

The most common choice at home is an electric sauna heater with stones; wood-burning stoves and infrared panels are also used. A rough rule is about 1 kW per 1.3–1.4 m³ of volume in a well-insulated cabin; add 10–30% if there is a glass door, windows or exterior walls.

With a correctly sized electric heater, a well-insulated home sauna usually reaches bathing temperature in 30–45 minutes. An undersized heater or poor insulation makes it take longer.

Cabin size, wood type, heater type and power, use of glass, lighting, control panel, and electrical and ventilation work. An exact figure comes once size and materials are chosen.
