Oval sauna

Oval sauna wall material is 44mm spruce material, and the end walls are 28mm spruce material. Bitumen is as a roofing material. In the steam room is used black alder/aspen. A kit contains a floor grids and a rear heat insulation plate. We use Tikkurila Pinja Wood Stain colors to finish our oval saunas. Pinja Wood Stain color is a fast-drying aqueous tonic stain and protects the surface from moisture, sunlight, and dirt, thereby reducing cracking of the wood surface.
