Common questions about manuals, registration, and support for this brand.
The base structure can be assembled in as little as one day with help, though we recommend setting aside a full weekend for the project with a few friends or family members.
No, never apply wood stain or paint to the inside of a sauna. These can off-gas at high temperatures and create a toxic environment. Only use exterior weather protection on the outside of the cabin.
You will need a level foundation base. A common method is building a wooden base frame using pressure-treated lumber on pre-cast deck blocks, screw piles, or concrete sono-tubes.
Long-haul sauna shipments are typically shipped on a flatbed truck. You must be present during the delivery window with a team of 2-4 people to hand-unload the pieces directly from the truck, or you can opt to rent a forklift.
