Saunum Heater Stones are manufactured from high-quality olivine diabase, a dense and durable material known for its excellent heat retention and resistance to thermal stress.
These rounded stones are pre-washed and sized between 2" and 4", making them ideal for proper airflow and even heat distribution inside sauna heaters. When heated, the stones store thermal energy efficiently and release it gradually, producing consistent radiant heat and optimal steam when water is applied.
Designed specifically for use with Saunum sauna heaters, these stones help maximize performance by supporting stable temperature output and enhanced steam quality. Their durable composition ensures long service life under repeated heating and cooling cycles.
