Red Cedar is the preferred timber for several reasons. First, it is one of the few woods naturally resistant to rot, decay and mildew, and as such can readily be used for indoor or outdoor construction. Also, because it is a very soft wood, Red Cedar allows your body to be in comfortable contact with the wood even though the air in the sauna room is very hot. Unlike some cedar wood, Western Canadian Red Cedar carries no harmful toxins or respiratory discomfort. Finally, nothing compares to the sweet, fresh scent of Western Canadian Red Cedar.. And, of course, no other wood has the aroma of Western Canadian Red Cedar, the wood of choice for sauna enthusiasts!
