Soapstone sauna heater Tulikivi Kaarna
Born of stone
Warm. Durable. Completely natural.
Description
Natural. Durable. Unique.
The Tulikivi Kaarna from the Kevo Collection is more than just a sauna heater; it's a piece of Finnish nature. Its genuine soapstone casing powerfully stores heat and gently releases it back, creating a soft, deep sauna climate that lasts a long time and is reminiscent of the origins of Finnish sauna bathing.
Stone design.
The clear, cylindrical shape combines timeless elegance with craftsmanship. Thanks to its height-adjustable construction, the Kaarna can be seamlessly integrated into the sauna bench or displayed as a standalone design object. With minimal safety clearances, it opens up new possibilities in interior design.
Uncompromising quality.
Made in Finland, awarded the Fennia Design Prize and available in two soapstone finishes: Classic (light) and Nobile (dark).

Assembly materials and technical documentation
The art of soapstone
For thousands of years it has rested beneath the forests of Finland – soapstone, formed by heat, pressure and time.
It stores heat like no other material, stays cool on the outside and releases it gently and evenly.
Each stone is unique, shaped by nature and created to last.
Two characters. One origin.
Classic
Bright and calm in its appearance.
The matte surface shows fine, natural shades and remains pleasantly warm to the touch.
A stone for light, clarity and quiet spaces.
Noble
Dark, deep and elegant.
Small crystals refract the light and give the stone a subtle vibrancy.
A material with expression, created for rooms with character.
