Sauna stones are an integral part of any sauna experience. Not only do they serve to store and release the heat generated, but they also help regulate the room climate by generating steam when infused. It is therefore crucial to choose the right type of stones.
Basically, experts recommend using sauna stones that have been specially manufactured and prepared for sauna heaters. These stones have been chosen for their properties, such as their heat resistance and low water absorption capacity. They are usually denser and more resistant to the extreme temperatures and humidity conditions that prevail in a sauna.
The use of normal stones in a sauna is not recommended. While normal stones may seem suitable at first glance, they can break or even explode at high temperatures, posing a potential hazard to sauna users. In addition, normal stones can contain dust, dirt and other impurities that are released into the sauna air when heated and can cause health problems.
When buying sauna stones, it is therefore advisable to choose stones that have been specially manufactured for sauna ovens. These stones are treated and prepared in such a way that they can withstand the extreme conditions in a sauna. They are also clean and free of any impurities.
When using a wood-burning sauna heater, the sauna stones should have a size between 10 - 15 cm. This size ensures sufficient air circulation and prevents the stove from becoming blocked by stones that are too small.
