Vent placement in a sauna isnโt arbitrary-it directly affects temperature consistency and user comfort. A common and effective passive ventilation approach includes:
โข Fresh air intake positioned low, typically near or below the heater
โข Exhaust vent placed diagonally opposite, often lower on the wall or beneath the bench
Why low intake near the heater?
Fresh air drawn across the heater is immediately warmed, creating gentle circulation rather than dumping cold air into the room.
Why avoid placing the exhaust too high?
If the exhaust is at ceiling level, you risk pulling the hottest air straight out of the room-increasing stratification and forcing the heater to work harder. In this example, the exhaust would ideally sit under the upper bench, however that wasnโt possible due to a concrete stairwell on the other side.
Bench height and ceiling height also matter. If benches are set too low in a tall room, occupants sit below the primary heat zone even with correct ventilation.
These factors should be considered during the design stage. Poor vent placement wonโt always be obvious during install, but it becomes very obvious once the heater is running.
Itโs important to review the manufacturerโs installation and ventilation instructions when planning your sauna, as designs may vary depending on the heater.
