About IKI Sauna Heaters
IKI Sauna Heaters, crafted by IKI-Kiuas Oy in Finland, have been a respected name in the sauna world since the late 1990s. The company prides itself on creating heaters that prioritize high stone capacity, open mesh designs, and exceptional steam quality—known as löyly in Finnish. Unlike many mass-produced heaters, IKI focuses on small-batch production, ensuring meticulous attention to detail and quality. Their signature open-sided mesh design reduces radiant heat and increases convective heat, delivering a gentler, more authentic sauna experience. This dedication to craftsmanship and performance has earned IKI a loyal following among sauna purists and designers alike.
