PROBLEM TO BE SOLVED: To provide a circulation type bathtub which has a simple structure and can feed sterilized water of a high sterilization effect. SOLUTION: This circulation type bathtub having a circulation pathway 6 which circulates bath water is equipped with a water level sensor 7, and a sterilized water feeding apparatus 11. The water level sensor 7 detects the completion of the drainage of the bath water from a bathtub 2. The sterilized water feeding apparatus 11 is driven by the detection information of the sensor 7, and feeds the sterilized water into the circulation pathway 6. The sterilized water feeding apparatus 11 electrolyzes water into alkaline water and acidic water, and either the electrolysis water of the alkaline water or the acidic water is made into the sterilized water. After the completion of the drainage of the bath water from the bathtub 2 is detected by the water level sensor 7, the sterilized water is fed into the circulation pathway 6 from the sterilized water feeding apparatus 11. Thus, the circulation pathway 6 can effectively be sterilized. COPYRIGHT: (C)2009,JPO&INPIT
