Complete Sauna Kit - Ready for Your Space

Our Carbon Smart™ indoor sauna kit arrives with all interior components precisely cut and tailored to your room dimensions. Simply provide the framing, insulation, electrical wiring, and exterior wall covering—we supply the rest. Building your dream sauna has never been easier or more affordable.

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.

Expert Support Available

Contact your Carbon Smart™ Specialist today for personalized guidance in creating the perfect sauna room for you and your family.

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.

Note: Wall boards run in the standard horizontal direction unless room width exceeds 8 ft; in such cases, an interior seam will be added where two boards meet to span the width.
