Exterior walls of sauna are wood

The bather had the exterior of the sauna finished in wood to match the rest of the basement in place of using drywall. It gives it a nice look along with the Douglas Fir sauna door. Note that there is a vent behind the sauna heater to the right of the door below the control that is sitting a little higher than it should, but having a vent is better than not having one at all.
