Grey Rounded sauna stones. Using the Olivine stone offers a soft steam experience because water flows easily to the lower stones, covering a larger stone surface and creating abundant soft steam.

These come in two sizes, the smaller 5-10cm are great for small electric heaters.

We recommend using a mix of rocks. The Olivine rounded stones are best as the top layer for any sauna heater to produce löyly. The Vulcanite angular stones are best in the lower layers, as they provide more surface for heating the water.
