Sauna Stones

Sauna Stones – Essential for Every Sauna Heater

At Polaris Sauna, we offer carefully selected sauna stones designed to deliver the best possible sauna experience. High-quality stones store heat efficiently, create soft and even steam when water is poured over them, and ensure your heater performs as intended.

Whether you use an electric sauna heater or a wood-fired stove, the right stones are essential for stable heat and enjoyable löyly.

Our Sauna Stone Selection

We supply professional sauna stones made from high-density olivine diabase, one of the most durable and heat-resistant materials used in modern sauna heaters.

Our range includes stones suitable for:

Electric sauna heaters
These stones are shaped and sized to fit heaters such as Harvia or HUUM models. Their structure allows efficient airflow between the stones and consistent steam when water is added.

Wood-fired sauna stoves
Larger rounded stones are ideal for wood-burning heaters, helping to maintain stable heat and producing a strong yet smooth steam experience.

Why Quality Sauna Stones Matter

Good sauna stones are critical for both performance and safety. Properly selected stones:

Store heat efficiently
Create soft and consistent steam
Protect the heater from overheating
Last longer under repeated heating cycles

Over time, sauna stones naturally break down due to thermal stress. Replacing them periodically ensures your sauna continues to perform at its best.
