Sauna room is a small room or independent cabin-like structure, and the temperature ranges from 100 to 140 degrees Fahrenheit. The purpose of sauna is to produce sweat through the combination of steam and heat. In a typical sauna process, users sit on a bench for 15 to 20 minutes to make themselves sweat. Fenlin recommends dry sauna, and our sauna room will provide you with a complete suit.
