Narvi Vulkaniitti Sauna Stones 10-15 cm Wood Heaters

Narvi Vulkaniitti sauna stones 10-15 cm are dark vulcanite stones for wood-burning sauna heaters.

Sized at 10-15 cm, they suit larger wood-fired stone compartments and hold heat for steady evaporation. The slightly darker tone looks neat against a black heater. Place the stones loosely with airflow between them and replace broken stones as needed.
