DOES THE HEAT AND HUMIDITY OF THE SAUNA CAUSE ANY PROBLEMS?
As the Sauna is not a steambath, 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% to 30% depending on if water is added to the stones. The reason for the low humidity is that the softwood absorbs the moisture, and the 180 ° F heat will dry out the moisture. Some of the heat will escape when the door is opened, but the heat is dry.
