Which stones should I choose for my sauna?
Sauna stones play an important role in ensuring optimal heat distribution and steam quality, and contribute to the overall sauna experience. Choosing the right stones is very important as it affects not only the efficiency of the sauna, but also its safety and aesthetics. In this article, we will discuss the main criteria for selecting stones and the most commonly used stones, as well as their advantages and disadvantages.
Main criteria for choosing stones
Heat storage and distribution:
- The stones should heat up quickly and retain heat for a long time. This allows for an even temperature and produces better steam.
- It is important that the heat is evenly distributed over the entire surface of the stones.
Thermal shock resistance:
- Bathroom stones should be resistant to temperature changes to avoid splitting or crumbling when they heat up and cool down quickly.
- Bathroom stones should be resistant to temperature changes to avoid splitting or crumbling when they heat up and cool down quickly.
Mechanical strength and durability:
- The stones must be durable and wear-resistant. This is particularly important for high-use saunas.
- The stones must be durable and wear-resistant. This is particularly important for high-use saunas.
Environmentally friendly and safe:
- It is recommended to choose natural stones that do not release harmful substances at high temperatures.
- It is recommended to choose natural stones that do not release harmful substances at high temperatures.
Aesthetics:
- The appearance and colour of the stones can contribute to the interior design and overall atmosphere of the sauna.
The most popular sauna stones and their properties
Basalt
Benefits:
- Excellent heat absorption, quick heat-up and long heat retention.
- Highly robust and resistant to temperature changes.
- Usually in black or dark grey, it adds elegance and modernity.
Disadvantages:
- May be heavier than other stones, making them more difficult to install and manage.
Gabbro-Diabass
Benefits:
- Dense, robust and resistant to thermal shock.
- A dark-coloured stone with an aesthetic appeal.
- Retains heat for a long time and distributes it evenly.
Disadvantages:
- Like basalt, it can be heavy, so care is needed when installing.
Talkochlorite
Benefits:
- A softer stone, which makes it easier to process and adapt to different designs.
- It retains heat well, warms up slowly and cools down slowly, creating a softer and longer-lasting heat.
- It has unique textures and colours, adding a sense of naturalness.
Disadvantages:
- Softness may make it less resistant to mechanical stress.
Jasper
Benefits:
- Aesthetically appealing thanks to its wide range of colours and textures.
- Good heat absorption and retention, but heat distribution may be less even.
Disadvantages:
- May be more fragile, so care should be taken when choosing.
Serpentine
Benefits:
- Good heat storage and distribution properties.
- A unique green palette that gives a distinctive and natural beauty.
Disadvantages:
- Lower resistance to degradation compared to basalt or gabbro-diabase.
Neutral or rounded stones
Benefits:
- The smooth shape helps to distribute heat evenly.
- Most are natural, but there are also artificial options that are more durable.
Disadvantages:
- Natural stones can be fragile and require more frequent maintenance.
Stone maintenance and replacement
Bath stones require regular maintenance. It is recommended to check the condition of the stones every year and to remove damaged or broken stones. This helps to maintain good heat distribution and safety. When replacing the stones, it is important to ensure that the new stones are properly spaced and not to use pieces that are too large or too small to ensure optimum air flow through the stone layer.
Installation and positioning of stones
Correct placement of the stones is critical to ensure good air and heat flow. The stones should be arranged in such a way as to allow free air movement through the stove. It is advisable to place larger stones at the bottom and smaller stones at the top to ensure better heat distribution.
Conclusion
When choosing sauna stones, it is important to consider their physical and chemical properties, as well as the intensity of sauna use and personal preferences. The right choice of stones will not only ensure optimum heat distribution and steam quality, but will also give your sauna a unique character and aesthetic.
