Know before you buy
Over time, sauna stones compact and lose their ability to retain and radiate heat efficiently. Replacing them ensures your heater maintains consistent performance and continues to produce high-quality steam.
These stones are specifically sized for Harvia KIP, KIP Wi-Fi, Cilindro, and Virta Wi-Fi heaters. Always check your specific heater manual to confirm the recommended stone size and weight capacity before installation.
Yes, you should rinse the stones with water before installation to remove any dust or debris from the manufacturing process. This prevents loose particles from circulating in your sauna air.
It is recommended to restack your stones periodically, typically once or twice a year depending on usage. This prevents the stones from settling too tightly, which allows for better airflow and more efficient heating.
The split-face finish creates a larger surface area compared to smooth, rounded stones. This design maximizes heat retention and provides a better surface for water to evaporate, resulting in more effective steam generation.
