Five years.  Find the Thermory barrel sauna warranty terms here.  Note: renting out your barrel sauna voids the warranty.  We hope to resolve this for SaunaShare hosts.  

During Use

• Only throw water on the heater, not on the walls or benches.
• Don’t wear wet swimsuits in the sauna, as water from these will damage the bench.
• To keep the bench fresh, we recommend using seat covers – these can also make it more comfortable to sit on the bench when it is hot.
• Keep an eye on the heating stones, as they may crack over time – whenever necessary, they can be replaced or more stones can be added.

After Each Use

• Wipe the benches with a clean, damp washcloth – don’t use running water to clean them to help prevent excess water from pooling on the wooden surfaces.
• Use appropriate cleaning products for the benches and other wooden components, reading the instructions first.
• After cleaning your sauna, allow the surfaces to dry and ensure that the room is well ventilated – we recommend leaving the heater on for at least half an hour with the air vent open and the door and windows closed.
• If possible, lift up the benches to allow them to dry better.

At least once each year

• Treat the wooden surfaces with a sauna-appropriate product – this should be done more frequently if the sauna receives intensive use.
• Clean all surfaces of the seating materials, walls and ceilings using a soft brush or cloth and a specialist cleaning product, following the instructions on the packaging.
• For deeper stains and soiling, gently clean the bench using a fine sandpaper before treating the sanded surface with a sauna-appropriate wood preservative.
• Avoid using cleaning agents that are unsuitable for saunas – for example, disinfectants bleach the wood and can spoil its surface.
• Inspect the fastenings on the benches and supports, tightening any screws if necessary; they may loosen over time due to changes in the wood caused by heat and humidity.

Things to avoid

• Don’t dry textiles in your sauna, as this can be a fire hazard – excessive moisture can also damage the surface of the wood.
• Avoid heating the sauna beyond the maximum temperature specified by the heater manufacturer – excessive heat may create a fire risk or cause the wood to warp.
• Never use a pressure washer or running water when cleaning your sauna, as excessive moisture can permanently damage the structure and surface of the wood.

How Wood Changes in the Sauna

• Wood is a natural material, and its surface may crack or bend when used in the sauna.
• This is normal due to the extreme and rapid changes in temperature and humidity that occur.
• The risk of wood deformation depends on the material and intensity of use – the effects are also more visible in wider boards.
• Wooden materials in the part of the sauna most exposed to the hot steam may darken over time.
• When new, thermally modified wood may give off a noticeable scent as the sauna is heated, but this will diminish over time.
