Maintenance & winter use

A few simple habits help keep your sauna or cold plunge clean, dry and ready for the next session. Start here, then follow the instructions for your exact model, heater and water system.

A simple care routine

• Before use: check for damage, leaks or unusual smells. Keep vents and the space around heating or cooling equipment clear.
• After a sauna session: switch off, let the cabin cool, remove towels and wipe moisture from seating and other contact surfaces. Let the cabin dry with its ventilation open as the manual directs.
• Before a plunge: check the water level, cleanliness and normal circulation. Follow the approved water-testing routine; clear-looking water alone does not establish that it is ready to use.
• Regularly: look over doors, seating, visible fittings and outdoor surfaces. Attend to a new leak, loose part or change in performance promptly.

Wood, seating and glass

Use a clean towel between your body and the wood. Once the sauna is cool, wipe benches and backrests with a soft cloth lightly dampened with water, then allow them to dry. Remove loose dust and debris from the floor. Clean glass with a soft cloth using only a method approved for the glazing and surrounding wood.

Avoid soaking the cabin, using a hose or pressure washer, or applying harsh chemicals and abrasive pads. Do not add interior paint, sealant, oils or fragrances without checking the model instructions.

Infrared saunas

Keep water, cleaning spray and wet cloths away from infrared emitters, controls and electrical connections. Heater surfaces differ between models, so use only the cleaning method specified for your panels or tubes. Switch off and let them cool before any permitted cleaning. Keep towels and stored items clear of heaters.

This applies to the One-Person, Single Recliner and Double Recliner indoor models, and the Compact, Grand and Rectangular outdoor infrared models.

Traditional saunas

Inspect the heater and stones only when the equipment is switched off and completely cool. Follow the heater manual for stone type, quantity, placement and replacement. If stones begin to crumble or heating changes, arrange a check before continuing use.

Only pour water onto stones if the exact heater instructions permit it, and follow the stated amount. Never add oils or cleaning products to the heater. Keep ventilation paths and heater clearances open.

This applies to the Compact and Large indoor traditional saunas, the Compact and Grand Thermo-Spruce outdoor saunas, and the Panoramic Cedar Barrel Sauna.

Indoor and outdoor care

Indoors: keep the surrounding room ventilated, wipe up drips and allow the cabin to dry after cleaning. An indoor model should stay in a suitable indoor location.

Outdoors: keep the base and drainage area clear of standing water and debris. Check the roof, joints and door after severe weather, and address signs of water entering the cabin. Ask for the approved exterior treatment for your wood and finish before applying a coating.

Keep access paths clear in winter. Follow the model instructions for snow, ice, wind and operating temperatures; outdoor placement does not establish a snow-load rating or unrestricted cold-weather use.

Cold plunge: water and filters

Rinse off before entering, remove visible debris with a skimmer and put the cover back on when the plunge is not in use. Keep the cover clean and allow equipment vents to breathe.

Use the water-care products, test method and acceptable readings approved for the supplied system. Water quality, frequency of use and the number of bathers affect maintenance. Filtration and ozone equipment do not replace the required water-care routine.

Check and clean or replace each filter as its instructions require. Some filters are washable and others are replaceable; do not assume the same method applies to every part. Follow the model procedure for switching off, draining, refilling and restarting. Never run the system without the required water level and circulation.

Pause use if the water becomes cloudy, smells unusual, circulation changes or a leak appears. Resolve the cause and restore the approved water conditions before using it again.

Cold plunge: winter and longer breaks

Freezing-weather operation and freeze protection have not been confirmed for the RestTone Cold Plunge. Before freezing conditions arrive, request the model-specific winterization instructions and arrange suitable protected storage or winterization.

Emptying the visible tub may leave water in the pump, chiller and pipework. A cover or a running heater alone should not be treated as freeze protection. For any longer shutdown, follow the full cleaning, draining, drying and restart procedure for the supplied system.
