If your sauna has some special features that affect the design (e.g. a hot water heater or a view window), you can mention them here. If these are visible in the floor plan, you can attach it to the request for quotation.
If you wish a quote for benches with a certain width of plank wood or for benches and panels of different materials, panels of different widths for the walls or a different direction of paneling for part of the walls, please mention them here. If you have in mind certain types of lights, a heater with accessories, the shade of a glass door or a glass wall, please specify here.
