Harvia standard sauna stones for electric heater

Harvia standard sauna stones for electric heaters absorb and hold heat, then release it gradually for steady sauna warmth. Mined in the Satakunta region of Finland, the stones can be used with electric or wood-burning heaters; pouring water over heated stones creates steam and löyly, the humid burst of heat associated with Finnish sauna bathing. Their porous structure allows air to circulate around the stones and helps distribute heat through the heater.
