Sauna Guide

Free sauna room planner and heater size calculator. Check kW, bench geometry, seating, headroom, ventilation and electrical load before you build.

Get the heater size to verify, the likely electrical load, and the bench fit to check before you compare models. A number you can take to the heater manual and your electrician. Choose the bench shape, then enter the depth and the distance from the upper bench to the ceiling. Wood-fired rooms need stove, chimney and combustion-air checks this sketch does not model. Enter the room length, width and height to size a heater.
