Enhance your massage with a professional 6 quart hot stone heater. Aromatherapy is perfect for heating stone for manicures, pedicures, and facials. This massage aid includes a Teflon coated removable water reservoir. The temperature control features a "pre-set" setting of 375 degrees to heat the water quickly as well as an "operating range" of 120-150 degrees that lets you rapidly bring the stones up to the proper temperature for therapeutic use. The warmer also maintains a constant, even temperature and the indicator light lets you know when the temperature is reached. This heater has a capacity of 42 stones so it is perfect for use with the 20, 36, and 40 piece stone set and it will not crack in the middle of a client treatment like a regular crock pot would if you drop a stone.
