Using our Sauna Heater Sizing Tool

Our Sauna Heater Sizing Tool is a simple form that requires you to enter the length, width, and height of your sauna, along with any glass dimensions. The tool then calculates the adjusted cubic feet of your sauna and recommends the appropriate heater size for your space.

Our sauna experts are also available to provide guidance and answer any questions you may have about sauna heater sizing or building a sauna. You can reach us through our website's chat or by calling our customer service line.
