ThermoWood Construction
The MW16 is handcrafted from premium ThermoWood, a thermally modified wood engineered specifically for outdoor environments. Through a chemical-free heat treatment process, the wood gains enhanced dimensional stability while reducing moisture absorption and susceptibility to decay.
This advanced construction material is one of the reasons Mande Spa USA saunas are built for long-term outdoor use. ThermoWood delivers the warmth and beauty of natural wood while providing improved durability in changing weather conditions.
Benefits of ThermoWood
- Improved resistance to moisture and decay
- Enhanced dimensional stability
- Reduced warping and twisting
- Reduced resin leakage
- Long-term outdoor durability
Built for Year-Round Use
- Suitable for freezing winter conditions
- Performs well in humid environments
- Designed for outdoor installation
- Handles seasonal temperature fluctuations
- Expected service life of 20+ years with proper maintenance
Designed for Shared Wellness
The MW16 was created for homeowners who want more space than a compact personal sauna while maintaining an efficient footprint. With seating for up to four people, it is ideal for couples, families, and those who enjoy sharing the sauna experience with friends.
The spacious bench layout, tempered glass elements, integrated LED lighting, and authentic European craftsmanship create a sauna environment that encourages relaxation, conversation, recovery, and daily wellness rituals.
More room. Same authentic sauna experience.
The MW16 delivers the ideal balance between compact efficiency and family-friendly comfort, making it one of the most versatile outdoor sauna options in the Mande lineup.
