The first-ever IKI sauna heater was invented by Jouni Kerrman in Finland in the late 1980s. It was also the first-ever sauna heater with an open mesh-framed structure surrounding a large mass of stones—a revolutionary heater design that would change the market forever.

At first, the road was rocky, but over time, not even the die-hard sauna traditionalists could deny the superiority of the new heater model. As with all successful inventions, others would soon follow, and the open mesh-structured sauna heater became the norm in the industry.

One by one, competitors have tried to copy the legendary IKI design. But only one is the Original.

Even today, IKI sauna heaters are handmade in Finland from premium materials such as stainless steel, with no compromises ensuring the ultimate löyly experience, exceptional durability, and the deserved cult status IKI has earned among sauna enthusiasts and customers around the world.
