Finlandia Sauna heaters and rooms require minimum care and maintenance. Basic household methods, including cleaning of Sauna room floor with a product such as Pine Sol or Simply Green, and occasional scrubbing of benches with a mild soap, is necessary for sanitary and odor-free atmosphere. When wood becomes dark or stained from perspiration, a light sanding will help to restore its beautiful appearance. Do not use sealers, paint or varnish on interior wood, as toxic vapors could be dangerous in the high temperatures of a Sauna.

NOTE: When figuring room capacities for number of bathers, allow 2' of bench space per person.
