Kastor Saga T - Through-the-Wall Wood- Burning Sauna Stove

Kastor Saga T through-the-wall, or tunnel sauna heater, is artfully uniting the invigorating heat of a traditional wood-burning sauna stove with the charm of a fireplace. With the heater positioned inside the sauna and the glazed fireplace door opening into an adjacent room - whether a lounge, dressing room, or living area - it creates a seamless flow between sauna bathing and fireside relaxation. 

This design not only enhances the experience but also provides efficient secondary heating for the adjoining space, while maintaining the cleanliness of your sauna interior, as any wood debris remains outside. 

With its meticulously considered proportions, the Kastor Saga T is as much a design feature as it is a high-performance heater. The carefully engineered firebox and expansive stone capacity  with a praiseworthy 140-190kg capacity for sauna stones, ensure long-lasting heat retention, consistent "löyly" (steam rising from the heater), and an atmosphere of refined luxury. 

Kastor Saga T is CE-marked for safety, equipped with adjustable legs for easy installation, and built to deliver years of reliable performance. Designed for those who value both exceptional craftsmanship and immersive sauna culture, it transforms the ritual of sauna bathing into a complete sensory experience.
