PROBLEM TO BE SOLVED: To provide bath equipment in which priming for a filter can be quickly conducted without making noise, such as air suction noise at the time a circulation pump is being operated, after a judgement has been made whether the circulation path is filled with water or not. SOLUTION: A priming operation is done in order to conduct water from a hot water supply heater 7 to a filter 8 when a judgement has been given as 'not circulating' in a checking process including a circulation judgement and water-level detection. Thus noise, such as air suction noise, is not made at the time the circulation pump 4 is operated, and hot water can be conducted promptly and directly to the filter.
