Premium Thermo Poplar Wood
Carbon Smart™ saunas are crafted exclusively with Thermo Poplar, a sustainably sourced and thermally modified wood that delivers exceptional performance and a beautiful aesthetic for your sauna interior.
Thermo Poplar
A thermally modified wood treated at approximately 374°F for optimal indoor sauna use. This medium modification delivers enhanced dimensional stability, improved resistance to humidity and temperature fluctuations, and a warm, rich tone—all achieved through a chemical-free process. Ideal for creating a naturally beautiful, long-lasting sauna environment. As part of the Carbon Smart™ line, this wood is responsibly sourced to support carbon-smart forestry practices.

Note: Your sauna shipment will include an all-glass door, though some photos may display a glass wall for reference. Backrests are shipped flat; if you'd like an angled backrest, additional spacers can be easily created on-site to achieve your desired pitch.
