Airmist prefab saunas come in completely self-contained wall sections which you can easily assemble in a matter of hours. The prefabs can be installed in any part of your home as long as you have (or can get) a water resistant floor in that area. If you move, you have the option of taking the prefab sauna with you. We offer the prefab saunas in both clear cedar and Nordic spruce, indoor or outdoor. Our cedar prefabs can be made to your exact specifications, since they are manufactured by Airmist in the USA.
