Product Highlights
Pinewood Construction
The barrel is built from high-quality pinewood, a material valued for its thermal insulation properties, lightweight structure, and warm, natural appearance. Pinewood is a widely used material in traditional sauna construction and provides a comfortable, inviting interior environment.
Barrel Shape Design
The cylindrical barrel form is a traditional sauna design that promotes efficient heat circulation throughout the interior. The curved walls minimize dead air space, allowing the stove to heat the cabin more evenly and with less fuel than a rectangular enclosure of comparable volume.
4.5KW Toule Wood-Burning Stove
The included 4.5KW Toule stove is a purpose-built sauna heater designed to heat the barrel cabin efficiently and maintain a consistent temperature throughout your session. Volcanic stones are included to generate steam when water is added.
Waterproof Bitumen Roof
The bitumen roof panel provides a waterproof, weather-resistant outer layer that protects the structure from rain, snow, and moisture. This makes the sauna suitable for permanent outdoor installation across a range of climates.
Tempered Glass Window
The tempered glass window allows natural light into the cabin and provides a view of the surrounding outdoor environment during your session, adding to the overall experience without compromising heat retention.
Accessories Included
Each kit includes volcanic stones for steam generation, a hygrometer for monitoring interior humidity and temperature, and a wooden bucket and scoop for adding water to the stones — everything needed to begin using the sauna immediately after assembly.
Multiple Size Options
The Thermora Haven is available in five capacity configurations — 2, 4, 6, 8, and 10 person — allowing you to select the size that best fits your space and intended use. Each size uses the same core construction and feature set.
