Custom means made to fit
You do not need to start with a sauna kit.
BuildSauna can create a custom residential sauna around an existing basement or home interior room, planning the dimensions, cedar, benches, door, ventilation openings and physical heater position together.
The result is a sauna designed for the actual space rather than a packaged footprint.
