DOES THE HEAT AND HUMIDITY OF THE SAUNA CAUSE ANY PROBLEMS FOR THE HOMEOWNER?
As the sauna is not a steam bath, there is no live steam to escape from the room and cause damage to the surrounding areas. The humidity of a sauna is only 10% (totally dry) to 30% (when water is added to the stones). The reason for the low humidity is that the softwood absorbs the moisture and the 180-degree F heat will dry out the moisture. Some of the heat will escape when the door is opened, but the heat is dry.
