Harvia sauna heater stones

Olivine diabase sauna heater stones

Olivine diabase sauna heater stones are the most common and used sauna stone for all heater types and is a subvolcanic rock mined in Western Finland. This traditional stone type is durable in structure and thanks to its high density, it stores and releases heat well. This guarantees perfect steam for sauna.

Sauna stones must be quarried and selected carefully to pass quality control, which confirms they are safe under intense heat and do not release any emissions. Harvia sauna stones are known to be safe under the intense temperatures of the sauna and retain heat for maximum efficiency.

All stones are thoroughly hand-selected and pre-washed so that replacing them is made easy every time. Prioritizing sustainability, stones that don’t meet the quality standards are repurposed for construction and other industries.

Sauna stones are often overlooked but remain one of the most important parts of the sauna. Appropriate quality, size, and placement of stones in the heater can have a significant effect on the heat retention and steam generation in the sauna.

Harvia heater stones fit to all sauna heaters – guaranteed by our constant quality control with the Geological Survey Institute of Finland. For this reason, our stones are always safe, clean, and ready to use – worldwide.
