Soapstone Sauna Heater Tulikivi Origin Rough Stone | inup Atelier Line
Raw. Timeless. Designed for generations.
Description
The Tulikivi Origin Rough Stone is made from solid Finnish soapstone, with its natural structure deliberately left visible. The surface appears powerful and calm at the same time. Each stone is unique and tells of its origin.
The Rough Stone surface expresses the original energy of the material. The irregular structure gently breaks the light and gives the stove an architectural presence that harmoniously blends into high-quality sauna rooms.
The combination of Tulikivi's decades of soapstone expertise and inup's design signature results in an object that goes far beyond mere function. A sauna heater that creates atmosphere and lasts for a long time.
Soapstone has an exceptionally high heat storage capacity. The heat is absorbed evenly and released gently over a long period. This creates a calm, pleasant sauna climate with a particularly soft feeling of warmth.
An object for people who seek durability.

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.
Grober Stein
Shaped by the character of a mountain.
The raw structure reveals soapstone in its most original form and makes the power of nature tangible.
A material with depth, created for lasting architecture and warmth for generations.
