Sauna Rocks
Olivine Diabase — The Heart of Authentic Löyly
Sauna rocks are the beating heart of authentic sauna bathing. The stones store the heat and transform water into smooth, enveloping steam — known as löyly.
Sauna Europe provides authentic Finnish Olivine Diabase stones, universally recognized as the gold standard of sauna rocks. Selected for exceptional mineral density, thermal longevity, and clean evaporative properties, they deliver unmatched steam quality for all electric heaters and classic wood-fired stoves.
Rocks are offered in 20 kg plastic bags or 1000 kg industrial size bags.
Authentic Mineral Quality
Finnish Olivine Diabase
Split quarried stones for superior heat retention & airflow
Finnish Olivine Diabase
The timeless mineral standard for traditional saunas. Naturally dense, durable, and free of harmful minerals.
Ideal for electric heaters with tight element spacing
Ideal for wood burning heaters
Premium Quarry Selection
Olivine Diabase has proven over decades to be the most reliable and effective stone type for traditional saunas. Its dense crystalline structure expands evenly when heated and handles rapid water cooling with less fracturing.
Why Olivine Diabase defines your sauna experience
Not all stones are suitable for saunas. Inferior rocks can crumble, release odors, or crack under intense heat, potentially damaging heating elements and obstructing air flow.
Sauna Europe supplies only thoroughly tested, quarry-sourced Finnish Olivine Diabase stones with dense crystal structures that absorb heat efficiently and release it gently — a perfect match for all electric and wood fired sauna heaters.

- Superior thermal shock resistance — withstands repeated rapid temperature changes with less fracturing
- Low thermal expansion to safeguard heating elements and preserve heater lifespan
- 100% natural and tested Finnish geological source without any harmful emissions or odors
- Angled split structure guarantees optimal air circulation around heating elements
- Perfect match for all electric and wood fired sauna heaters with generous stone capacity
