25 lb Box of Replacement Sauna Heater Rocks / Stones

Perfect for most models of sauna heaters. These are high-quality stones that generally ship the same day of the order! 

IMPORTANT! Peridotite is a dense, course-grained igneous rock. Only igneous peridotite stones should be used in a sauna heater.  The wrong stones can crack or even explode.  Our stones produce soft heat when water is applied– an essential part of the sauna experience.
