Sauna rocks are the heart of steam production, absorbing and holding the heater's energy and releasing it as soft löyly when splashed with water. Dense, heat-durable stone graded for sauna use.

Care

Allow textiles and wood accessories to dry fully between sessions; store away from standing water. Follow any product-specific instructions on the label.
