Narvi Heater Accessories

Sauna stones (or rocks) are one of the most important elements of a sauna experience. Hot rocks are the ones that increase the room temperature, and they create the pleasant “löyly” when water is being poured on them. The goal is to heat up and keep as many rocks as possible hot, instead of heating up metal and other materials. Stones bring the “good” heat to a sauna room, while hot metal brings radiation heat.

For electrical sauna heaters we recommend smaller stones (Ø 5–10 cm) and for wood-burning sauna stoves we recommend bigger stones (Ø 10–15 cm). The stone type can be either olivine diabase (the most common stone type) or vulcanite, which has a bit darker tone.
