Know before you buy
Olivine diabase is highly valued for its exceptional thermal capacity and resistance to extreme temperature fluctuations. It is dense enough to store heat efficiently while remaining durable enough to prevent cracking or crumbling over repeated heating cycles.
The rounded shape creates natural gaps between the stones when stacked in the heater. This allows air to flow freely through the pile, ensuring the heating elements are properly ventilated and the sauna reaches temperature more evenly.
A 44 lb box is standard for many residential sauna heaters, but you should always consult your heater's manual for the specific weight capacity. Overfilling can restrict airflow and damage the heating elements, while underfilling will result in poor steam production.
Yes, it is recommended to rinse the stones with water to remove any dust or debris from transport before placing them in your heater. This prevents any initial odors or particles from circulating in your sauna air during the first heat-up.
Even high-quality stones like these will eventually degrade due to constant thermal expansion and contraction. It is best to inspect your stones once a year and replace any that show signs of cracking or crumbling to maintain optimal steam quality and heater safety.
