Some stones may develop cracks or split during the first few heating cycles or after prolonged use. This is a normal characteristic of natural sauna stones.
Maintenance
Regularly inspect and rearrange the stones to maintain proper airflow. Remove stone dust, loose fragments and heavily damaged stones. Replace worn stones when necessary.
