Product Highlights
ThermoWood Construction
ThermoWood is produced by heat-treating timber at high temperatures, which reduces moisture content and improves dimensional stability. The result is a wood that resists warping, cracking, and biological decay without the use of chemical treatments — making it well suited for outdoor sauna applications.
Scandinavian Cube Design
The SAK47582 features a compact cube-style exterior with clean lines and a tempered glass door, consistent with traditional Scandinavian sauna aesthetics. The design is functional for both standalone outdoor placement and indoor installation.
Integrated LED Lighting
Built-in LED lighting is included in the kit, providing ambient interior illumination without requiring a separate lighting installation.
Harvia Heater Options
Choose from the Harvia M3 wood-burning stove with stones, the Harvia KIP 6.0KW electric heater with built-in controller in Black, or the same unit in Silver. A No Heater option is also available for buyers who prefer to source their own compatible heater.
Tempered Glass Door
The tempered glass door provides a clear view of the interior and exterior while maintaining heat retention. Tempered glass is rated for high-temperature environments and is more impact-resistant than standard glass.
Indoor and Outdoor Installation
The kit is designed primarily for outdoor use but can be adapted for indoor installation. Indoor setups omit exterior components such as roof shingles, metal bands, and exterior siding, and require adequate ventilation and an appropriate floor surface.
Fast Shipping
Orders ship within 1–3 business days and are delivered within 5–10 business days to USA addresses at no additional shipping cost.
