These Hard Rock Sauna Stones have been found to be especially good for Sauna use. The heat retainment, rough surface and natural geologic properties make these ideal for any Sauna heater.
This box contains both larger rocks, intended for the bottom of the heater and smaller rocks, intended for the top of the heater. Stack the stones with plenty of room in between to allow proper air circulation. Stones should be washed periodically and replaced at least biannually, depending on frequency of use.
With these stones you can trust that the Sauna is being heated with the right stones that will not crack, produce strange odors, discolor or even disintegrate. Box contains 50lbs (22kg) of authentic sauna stones.
