How Do You Construct a Sauna?
- 1). Get a plan or simple design for your sauna. It must be a rectangle and tall enough for you to stand in.
- 2). Construct a ceiling and four walls with wood. Leave space for a door and at least two vents.
- 3). Insulate the inside with a layer of fiberglass about 3 inches thick. Cover the fiberglass with wood.
- 4). Build benches in the sauna with wood. Brace the benches on the sides and in the middle.
- 5). Install a door. Use a wood door because metal would get incredibly hot.
- 6). Install a stove. The size depends on the size of the sauna.
