The start of the season for extended sauna enjoyment is just around the corner. If the sauna has been taking a break during the summer months, it is advisable to check that it is working properly and inspect its various components before your first sauna session. One of these components is the sauna stones. Over time, the stones can wear down and lose their effectiveness. Replacing sauna stones is therefore an important part of sauna maintenance.
1. Why replace sauna stones?
Sauna stones are not just an aesthetic feature of the sauna; they also store heat. Over time, regular use and extreme temperature fluctuations can reduce their effectiveness. Worn stones can impair heat storage and distribution, which can negatively affect the sauna experience. That is why it is important to dispose of old stones and replace them with new ones.
2. Visible signs of worn sauna stones:
• Cracks: Cracks in the stones may indicate that they are not able to withstand temperature fluctuations.
• Discoloration: Discoloration may indicate deposits and dirt that interfere with heat transfer.
• Low heat output: If the sauna does not reach the desired temperature despite taking longer to heat up, the stones may have lost their ability to store heat.
3. When to replace them:
It is advisable to check the sauna stones every few years and replace them if necessary. The exact timing depends on how often the sauna is used and the quality of the stones. An unpleasant smell in the sauna or a noticeable drop in heat output can be signs that replacement is needed.
4. How to dispose of old sauna stones:
- Remove the stones: Turn off the sauna and let it cool down. Carefully remove the old stones from the sauna heater.
- Clean them: Remove dirt and deposits from the stones. You can do this with a brush or a pressure washer.
- Environmentally friendly disposal: Old sauna stones can generally be disposed of with household waste. Be sure to follow local regulations and recycling guidelines.
5. Replacing them with new stones:
- Choose the right stones: Use only high-quality sauna stones that are suitable for your specific sauna and its performance.
- Installation: Arrange the new sauna stones evenly in the sauna heater.
- Heating phase: Heat the sauna with the new stones at a low temperature to burn off any residue and activate the stones.

Conclusion: The stones are the heart of the sauna
Sauna stones are the heart of every sauna, and regular maintenance and replacement are essential for an optimal sauna experience. Properly disposing of old stones and replacing them with fresh, high-quality ones ensures that the sauna can work to its full potential. This often-overlooked but important aspect of sauna maintenance deserves proper attention. That way, every sauna session can be a revitalizing experience for body and mind.
