The Kota Sauna Sand Timer is a simple yet effective way of monitoring the time you spend in the sauna. The sand timer rotates/pivots around a central point that is connected to a back board. This back board is in turn secured to your sauna wall by means of two screws. This allows the user to rotate the sand timer continuously 360 degrees every time a new session begins. There is a choice of woods to match or contrast with your sauna interior: Pine, Aspen or Cedar
