Ventilation in a sauna is not optional. It's how the heat circulates correctly and how humidity stays controllable.
Fresh air enters low — near the floor below the heater. Hot air and steam exit high — near the ceiling on the opposite wall.
Without proper ventilation, the temperature stratifies: the top bench is scalding, the bottom is barely warm, and the steam distribution is uneven.
Every Mande sauna is designed with the correct ventilation geometry built in. You don't need to modify anything. But you do need to leave the vents open.
