Why Thermally Modified Wood?
Thermal modification isn't just a treatment—it's a complete transformation. The wood is heated to 200°C, permanently altering its cellular structure for exceptional durability. Unlike untreated timber that requires annual maintenance and may need replacing within 5-7 years, thermally modified wood maintains its integrity for decades. The naturally darker, richer colour ages beautifully without fading to grey, creating a stunning addition to any garden.
Perfect For
- Couples seeking a private wellness retreat
- Homeowners with limited garden space
- First-time sauna buyers
- Year-round outdoor wellness enthusiasts
- Property developers adding luxury amenities
