Premium Olivine Diabase Sauna Stones – Maximise Your Löyly, Minimise Energy Waste

Not all sauna stones are created equal. Our olivine diabase stones are the gold standard for any sauna heater—known for their durability, high thermal conductivity, and the rich, soft steam (“löyly”) they produce. Unlike degraded or poor-quality stones, fresh olivine diabase heats up faster, improves energy efficiency, and protects your heater from damage.

If your sauna takes too long to heat, the steam feels weak, or you notice crumbling stones on the floor, it’s time for a refresh. Replacing your sauna stones every 1–2 years keeps your sauna efficient, safe, and satisfying.

Choose stones that elevate every session—because the perfect löyly starts with quality.
