Hello!
I’m getting excited about the possibility of building a wood-fired sauna, but even after plenty of internet research I still have lingering concerns about things like carbon monoxide and asphyxiation. I understand that all properly built wood-fired saunas have some level of ventilation incorporated into the design, but when a fire is actively raging in a stove in a small, confined space, how does this not consume dangerous levels of oxygen and create asphyxiation risks and/or produce harmful monoxide or other fumes in the hot room? I have seen designs where the stove appears to be directly vented through a wall to the exterior (which seems like an excellent idea), but most sauna set-ups I’ve seen don’t appear to have this.
Any thoughts or suggestions from well-experienced sauna users?
