Olivine Diabase Sauna Heater Stones, Rounded, 10-15cm
The Harvia R-995 Olivine Diabase sauna heater stones resemble rounded stones from the great rapids, bringing a softer tone to your sauna along with multiple benefits. These stones produce gentle steam, allowing water to flow smoothly to the lower layers. This ensures the water reaches a larger surface area, creating abundant steam with a softer feel. We recommend using angular stones in the bottom layers as they give more heating surface area for the water. This combination provides the best result for soft steam and effective heat generation, especially in heaters with smaller stone capacity. Compatible with electric heaters and wood-burning stoves, the Harvia R-995 sauna stones ensure consistent heat distribution and a smooth, enjoyable steam experience.
