20kg Box - Black Vulcanite 10-15cm
Harvia Black Vulcanite Stones (Ø 10-15 cm) are large granular, dark grey stones. When wet, the stone shines black making it a great-looking option with selected Harvia heaters. The stone’s volcanic origins date back to ca. 2000 million years. Based on its structure and composition, vulcanite is a good choice for a sauna stone as it is hard and durable.
Sauna Heater Stones store heat directly from the sauna heater. During your sauna session, throw water onto the hot rocks, for immediate steam. The steam blends with the dry air in the sauna to create an enjoyable and relaxing atmosphere.
Check the right stone size for your heater from the heater manual.
It is recommended that all stones should be washed to remove any stains or dust that can cause any odours during the first few times of using the heater.
