Designed to thrive in wet, snowy, or desert climates - the Thermory Barrel Sauna Kit outperforms and outlasts barrel saunas that use unmodified wood.
Stocked in the USA, these premium barrel saunas come from Northern Europe where thermal modification of wood is common, and they are VERY good at it.
Thermory is a global leader in the thermal modification of wood with factories in Estonia and Latvia. After X-raying for imperfections, then perfectly milling the boards to European standards, the boards go through the thermal modification process.
This involves placing the wood through a vacuum with low oxygen, temperatures around 400°F, and specific humidity to make the Nordic Spruce completely stable and more durable than cedar.
The process also darkens the wood and removes VOCs.
The list of benefits is long...
- Beautiful
- Moisture and Rot Resistant
- Environmentally Friendly
- Healthier to Breathe (Removes VOCs)
- Â Durable
Here’s one of their processing plants in Estonia:
This process along with expert design results in the Thermory Barrel Sauna Kit, the ultimate outdoor barrel sauna designed to endure the harshest environments.
Now you can relax, refresh, and reconnect with friends and family knowing you made a wise investment that will provide years of wellness.
Trust us, you’ll want this new wellness routine of yours to last.
Put it on any flat, hard surface. We recommend a concrete pad or deck but pavers or a gravel bed work well too.
Thermory’s design team has meticulously crafted this barrel sauna to overcome common issues found in other barrel saunas. With a spacious interior, innovative insulation, and more substantial boards, all Thermory Barrel Sauna Kits ensure a superior seal and comfortable sauna experience.
The kit comes with pre-milled materials and a user-friendly proprietary construction process, making installation a breeze.

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.
Yes, Theermory barrel saunas come with a floor kit to level out the bottom of the sauna. This also makes an excellent raceway for hiding cables. Â
We’ve found that enough air enters through the drain holes below the heater to provide excellent air flow through the sauna and out the exhaust vent near the door.
