DIY Outdoor Sauna
This was a last minute project I built in Fall 2009. The size is approximately 5’x7’ with 7’ ceilings. Most of the dimensional specs come from experts in the field on sauna construction and how heat builds within these rooms. This DIY sauna project took about 2+ months of weekend work (some weekday nights). Since the walls are 2×4 I had to gain as much insulation as possible so I used a 2” foam board between the joists. Floors have 4”. I then wrapped the entire inside with a reflective moisture barrier which was then taped to seal all seams. Horizontal strapping followed at 16” O.C. which also created an air space so the finished wood could dry evenly. 95% of the sauna (walls, benches and ceiling are Eastern White Pine. I did use a little cedar mainly as a darker accent for the baseboard and door. Flooring is Slate tile. Lighting is 4 sections of rope lighting found at any Home Depot or Lowes. I opted to get the shorter sections in case one burt out. Replacement of one section would be easier and less expensive. Lighting is also tied into a dimming wall switch located outside the sauna next to the door. Some items not shown at time of photo is a sliding vent located just above the light rail for ventilation and circulation, and humidity / temp gauge. I also have yet to photograph the door I built. I’ll update again after winter to give a performance overview.
