These traditional, high quality sauna stones are noted for their durability and excellent soft steam created when water is applied. These stones are can be fitted in any sauna heater. They are available in two sizes: 5-10 cm and 10-15 cm. In the case that heaters require both grades, larger stones should be used at the base with smaller grade stones added to the top of the heater. Each box comes with approximately 20 kg of premium Finnish olivine diabase sauna stones.
For both wood burning and electric sauna heaters, stones should be filled to the rim but not exceed it. Stones should be placed to maximise the space in between. This ensures a perfect loyly as the water can cascade easily down the length of the large heating capacity and allows air to flow between them with ease.
