A better way to vent your sauna is to allow for about a 1/2″ or so crack along the bottom of your sauna door.
Why is this a good idea?
- No extra engineering of having to put an air intake vent in one of your walls.
- Air coming in through a crack in the bottom of your door will help keep your floor dry, the incoming air acts as a gentle blow dryer, running along the floor to feed air your sauna.
Keep it comfy.
