Ceiling Height
A 7′ ceiling works best for holding heat where it’s most comfortable. If your ceiling is higher, consider raising the benches to keep bathers in the optimal heat zone.
Vents
Ventilation is for fresh air, not moisture removal. Place the intake vent low under the heater, with the exhaust high on the opposite wall for best air flow.
Drainage
A floor drain isn’t essential for most home saunas, but commercial setups may require one. Always check local building codes.
Plumbing Inside The Sauna
It’s best to avoid water lines inside the hot room to reduce safety risks and protect electrical systems.
Flooring Options
Durable, water-resistant materials like tile, sealed concrete, or vinyl work well. Many customers add duckboards for comfort and style.
Electric Setup
All sauna wiring should be done by a licensed electrician to meet safety standards and warranty requirements.
Heater Size
Plan on 1 kW of power for every 50 cubic feet of interior space. For outdoor installations or spaces with less insulation, a slightly larger heater may be needed.
Insulation Levels
R-19 for walls and R-30 for ceilings are ideal. At a minimum, use R-12 insulation for proper heat retention.
Lighting
Only use fixtures designed for high heat and humidity. Both wall-mounted and ceiling options are available.
Bench Layout
Allow 2–3 feet of upper bench space per person. A longer bench (5–6 feet) lets bathers fully stretch out for relaxation.
