Premium Thermowood Construction
Our barrel saunas are constructed from 46mm Thermally Modified Pine staves, a high-performance timber specifically designed for durability in outdoor environments. Thermowood is produced through a natural heat modification process that significantly improves the timber’s resistance to:
- Moisture
- Decay
- Pests
- Warping and dimensional movement
The result is a stable, long-lasting outdoor sauna with a beautiful natural finish that ages gracefully over time. Stainless steel tightening bands and Finnish-quality roof shingles protect the sauna from the elements while complementing the natural timber finish.
