1. Use only clean water on Sauna stones. Do not use spa or pool water as it will destroy your heater.

2. Clean water should always be used in Sauna buckets and water should be dumped out after every use. Scour buckets and dippers occasionally when film collects from usage. Use plastic bucket liner in bucket to prevent water leakage.

3. Scrub benches with a soft brush, using soap and water or a mild disinfectant, when needed – about once a week in commercial Saunas, or depending upon sauna usage. For sanitation, each bather should sit or lie on a towel (this will prolong bench life).

4. Remove possible removable flooring and wash waterproof floor with disinfectant (e.g. Pine Sol) about once a week or as often as needed. Hose off removable flooring to clean.

5. To maintain the beautiful appearance of the Sauna heater, remove water stains by wiping a damp cloth occasionally.

6. Our Sauna Heaters require no special maintenance when properly installed by a qualified electrical contractor. After 1 year of usage, the rocks may need replacing if they have crumbled or powered.

7. We strongly recommend a floor that can be easily cleaned (concrete, ceramic tile, or a poured type of flooring). When this is provided, the Sauna can be easily cleaned and kept in a sanitary condition with little effort. A carpet is NOT recommended for a Sauna! A carpet becomes a perfect breeding ground for bacteria in the moist conditions of a Sauna, and a carpet promotes the spread of foot diseases such as athlete‘s foot.

8. In new construction, a floor drain should also be provided, especially in commercial Saunas for sanitary cleaning and maintenance.

9. Seal wood around glass in door – inside and outside – with Thompson‘s Water Seal to prevent warpage.

10. When Sauna wood becomes stained from perspiration, the wood may be lightly sanded with fine sandpaper to restore a beautiful appearance. We do not recommend stains or sealers as toxic vapors may appear when heated. However, 2 coats of Thompson‘s Water Seal may be used on the wood benches in a commercial Sauna, so that the wood may be more easily cleaned and kept sanitary – the wood will not absorb perspiration.

11. The Sauna room will heat faster if the higher vent is kept in a closed position when heating. The lower vent may always be kept in an open position.

12. Required warning signs should be posted according to the instructions.



  • Owner of the sauna heater must make sure that the sauna heater is turned off correctly every time after bathing.
  • Owner of the sauna heater must obey these maintenance instructions!
