Harvia Rounded Stones (10-15 cm)

Harvia Rounded Stones (10-15 cm) resemble nature’s rounded stones from the great rapids. The use of this stone introduces a soft steam method; the pouring water runs easily down to the lower stone layers. This way the water reaches more surface area, generating more steam with a softer touch. This method of using rounded stones on the top layer of the heater works in all sauna heaters.

We recommend the use of 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.
