Harvia sauna stones 20 kg for use in heaters.

Sauna stones with sharp corners are easy to stack, allow better air circulation and store more heat, thus ensuring optimal steam production in the sauna.

They are extracted from sub-volcanic rocks found in western Finland and are suitable for all types of heaters.

It is recommended to rinse all stones to remove any stains or dust that may cause an unpleasant odor during the first few times of using the heater.
