Product Description

The atmospheric Kastor Karhu T, “Bear”, tunnel wood- burning sauna heater - also known as a fireplace-style sauna heater- seamlessly combines the ambience of a traditional wood-burning sauna with the inviting glow of a fireplace. Ingeniously designed, the heater unit is positioned within the sauna, while the fireplace door opens into an adjacent room - whether that's a dressing room, relaxation lounge, or a living area. 

This refined configuration allows you to enjoy the invigorating "löyly" (sauna steam) before transitioning to the warmth and atmosphere of the fireplace. Beyond creating a multi-sensory experience, the Kastor Karhu T also provides efficient secondary heating for the adjoining space, while keeping your sauna floor pristine by ensuring any wood debris remains outside the sauna. 

Meticulously crafted with clean, elegant lines, the Kastor Karhu T complements both modern and traditional sauna interiors. Its expertly engineered firebox and optimised stone compartment deliver lightweight handling without compromising on superior heat performance and longevity. 

Each Kastor Karhu T heater is CE-marked for safety, equipped with adjustable legs for effortless installation and features a 115mm internal flue diameter. Available in models designed for sauna volumes ranging from 12m³ to 30 m³, it offers tailored heating solutions for various sauna sizes. 

Please note: The front frame is sold separately. 

*Suitable amount of sauna stones, flue kit, front frame and heat shielding to be purchased separately.
