With a prefab kit, the walls and ceiling are prebuilt panels finished on both sides. Panels are insulated with a moisture barrier. They also include a duckboard floor and a door. You assemble the components into a free standing sauna. These kits also include the equipment such as sauna heater and controls.
Precut Custom Sauna Kits
A precut custom kit includes all the panels, floor, and door as the prefab kit. However, these kits are designed and built to fit your unique space. They are attached to frame walls rather than free standing units.
