Since I became a homeowner several years ago, I always wanted to build a Sauna. I blame it on being raised in Michigan's Upper Peninsula where there are many people of Finnish decent. A sauna is a small hot room(140 F to 200 F) where you go to sweat. It promotes relaxation and supposedly good health. I’ve seen a few inside homes and a few outside homes, also some in spas and health clubs. A popular but somewhat peculiar activity is to heat yourself in the sauna then either roll in snow or jump into cool water.

Shown in the first two photos are examples of traditional outdoor Sauna you might find in Finland or other countries in northern Europe. The third photo is my building.
