Product Highlights
Compact Outdoor Footprint
At 71.0" × 63.0" × 85.0", the SAK20378 is sized for outdoor spaces where a full-width sauna may not fit. It provides a dedicated sauna area without requiring a large yard or deck.
Natural Spruce Cabinet
The exterior and interior are constructed from natural spruce, a wood commonly used in outdoor sauna applications for its dimensional stability and moisture resistance over time.
ETL-Listed Electric Heater Options
The Toule and Hravia electric heater options are ETL listed, confirming they have been tested and certified to applicable North American safety standards. Available in 6KW (2–4 person) and 8KW or 9KW (4–8 person) outputs.
Wood-Burning Stove Options
For buyers who prefer a traditional wood-fired sauna, two stove options are available: a Wood Heating Stove rated for 2–10 persons and a Heating Stove rated for 2–8 persons.
Included Monitoring and Control Equipment
Each unit ships with a control panel, thermometer, and hygrometer so you can monitor temperature and humidity throughout your session.
Waterproof Roofing System
The integrated waterproof roofing is designed to protect the sauna interior from rain and weather, supporting permanent outdoor installation without requiring a covered structure.
