Wood option: Japanese Cedar
FSC-certified Japanese Cedar (Sugi) — naturally rot-resistant from the wood's own oils, classic warm cedar aroma, warm reddish-brown tone with pink undertones.
Japanese Cedar (Sugi, Cryptomeria japonica) is sourced from Japan and certified by the Forest Stewardship Council (FSC). It is naturally rot-resistant from the wood's own natural oils, with no chemical treatment required.
- Treatment process
- None required. The wood's natural chemistry provides rot and insect resistance.
- Color
- Warm reddish-brown with subtle pink undertones and natural grain variation. Darkens slightly over time. Develops a natural patina with use.
- Aroma when heated
- Distinctive warm cedar scent that intensifies with cabin temperature. One of the most recognizable wood aromas in traditional sauna culture.
- Thermal behavior
- Low thermal conductivity. Bench surface remains comfortable to touch at high temperatures.
- Durability
- Naturally rot-resistant from the wood's own natural oils. Resistant to insects and decay. Does not require chemical treatment for outdoor use.
- Heritage
- Sugi is the national tree of Japan. It has been used in Japanese temples, traditional architecture, and ofuro and onsen baths for over a thousand years — a heritage that pairs naturally with the sauna ritual.
- Best for
- Buyers who want the classic cedar sauna aroma, the warmer reddish wood aesthetic, the heritage of a wood used in Japanese baths for centuries, or the natural rot resistance of the wood's own oils.
