Traditional wood burning saunas really go to the heart of the pure sauna experience. The incomparably soft heat, lush hiss of steam and relaxing crackle of a wood-fueled fire… even the ritual of tending the fire. It is a heritage sauna enthusiasts have treasured for thousands of years. Captured and reinterpreted for modern living in today’s wood burning sauna heaters.
