A four-person traditional sauna built for consistent, high-temperature use. Canadian Hemlock construction. 6.0kW Harvia electric heater certified to UL standards. Double-tiered bench design accommodates full sessions for up to four users or extended single-user sessions.
Traditional Finnish-style saunas operate at higher ambient temperatures than infrared formats — typically 150–195°F — producing a cardiovascular and thermoregulatory response documented in the peer-reviewed literature. A 20-year Finnish cohort study (Laukkanen et al., JAMA Internal Medicine, 2015 — PMID 25705824) found that sauna use four to seven times per week was associated with significant cardiovascular adaptation outcomes compared to once-weekly use. Heat shock protein activation through repeated heat exposure has been documented by Kregel KC (Journal of Applied Physiology, 2002) as associated with cellular stress adaptation and connective tissue recovery.
This unit reaches the temperature range used in that research. The included water cask and ladle support traditional steam generation for users who prefer higher relative humidity sessions.
Construction
Canadian Hemlock wood — interior, exterior, and bench surfaces. Double-wall panel design minimizes heat loss and maintains session temperature stability. Extra-thick tempered glass door.
Session Equipment
Interior thermo-hygrometer for temperature and humidity monitoring. Ventilation system for air circulation during use. Water cask and ladle included for traditional wet steam sessions.
Installation Note
This unit requires a dedicated 240V electrical circuit. Installation must be performed by a licensed electrician. Confirm circuit availability before ordering.
