Product Overview
Olivine diabase is one of the most durable and heat-stable stone types for sauna use. The split-face cut exposes more raw stone surface than rounded stones, which means more contact area for water — producing a denser, more enveloping steam when you ladle water for löyly.
Stack these stones loosely following your heater manufacturer’s guidelines to maintain proper airflow around the heating elements. Many heaters require more than one box — check your heater’s stone capacity before ordering.
Note: Natural stone varies in shape, color, and texture. Stone dust may be present from shipping — rinse stones before first use. Replace any cracked or crumbling stones per your heater manufacturer’s recommendations. Harvia recommends replacing sauna stones every 1–2 years depending on frequency of use.
