Ventilation is one of the most important and most misunderstood parts of sauna design. Without the right airflow, saunas can feel stuffy, heat unevenly, and trap moisture. We provide ventilation design as part of every plan, including intake and exhaust placement, airflow strategy, and guidance for passive or mechanical solutions based on your heater type and room location.

What Good Sauna Ventilation Achieves

• Fresh air at the bench level where people sit and breathe.
• Even temperature distribution from floor to ceiling.
• Reduced moisture buildup in walls and adjacent rooms.
• Faster warm-up times and improved energy efficiency.

Ventilation Strategies We Design

We evaluate the heater type, room size, and the location of the sauna within the home or building. That informs whether we recommend passive ventilation or a mechanical assist. We then define intake and exhaust placement and size based on the best airflow path for that layout.

Key Factors We Consider

• Heater placement and heat plume behavior.
• Bench heights and occupant breathing zone.
• Exterior wall locations and insulation assemblies.
• Makeup air path and exhaust termination location.
