Rounded Olivine Diabase Sauna Stones 33 lbs Steam

Rounded Sauna Stones are 33 lbs of tumbled olivine diabase heater stones with a smooth mountain-stream shape. Placed as the top layer, the rounded form lets water flow down to the lower stones.

That steady flow raises steam capacity and gives the heater a finished look. Suited to home saunas where deep löyly matters.
