Product description

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. Over time, even the highest quality diabase fractures. Depending on usage, stones should be replaced once every year to every two years. This is important to maintain the voids between stones remain large enough for the through flow of water and air, and because the heat capacity of the stones relates to the size of the stones themselves. A simple way to check yourself is to measure the stones in comparison to your closed fist, once stones become smaller than this, they should be replaced.

For information on how to correctly load the stones into your heater, see our helpful guide including video demonstrations available here.
