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.

Performance compared to Nordic Spruce: Identical. Both woods are paired with the same 42 mm wall construction, the same triple insulation, the same heater, and the same hardware. The choice is aesthetic and aromatic.
