Sauna Heater Stones 4-6 In, 44 lbs | Harvia

Stones hold heat well, give good steam.

We purchased two boxes of these stones for our Harvia Linear 16 heater, and then purchased a third box for filling up a cage that wraps around the interior portion of the chimney. These stones hold heat well and seem to be high quality. They also give off good Loyly and we have been enjoying our sauna experience with the help of these stones, which come from Finland.
