An efficient sauna ventilation system is an important component of a properly working home sauna. Whether you operate your sauna as a wet steam room or you use dry, infrared heat, you should ventilate the area with a system that allows several complete air changes every hour.
All wet and dry home saunas require some sort of ventilation to bring fresh air into the sauna. A simple but efficient system is to leave an open space at the bottom of the entrance door. Since hot air rises and cold air stays near the floor, you wont feel the draft as you sit on one of the benches. A crack of anywhere from to several inches will provide sufficient ventilation to recycle the air for a comfortable sauna session.
A better system to ventilate wet and dry saunas is to provide an opening in the wall just behind the sauna room heater. This intake vent should be located several inches above the floor to provide the fresh air supply. The outlet should be located on the opposite wall close to the ceiling. This opening will remove the used air from the home sauna, thus ensuring several complete air changes and efficient ventilation.
