PROBLEM TO BE SOLVED: To more suitably clean bath water by providing a bath water cleaner which can control the amount of ozone gas generated from an ozonizer 12 to maintain the constant ozone concentration in bath water. SOLUTION: An ejector 8 is installed in the middle of a circulation passage 2, and the ozone gas generated from the ozonizer 12 is supplied from the ejector 8 into the circulation passage 2. An ozone sensor 3 is installed on the upstream side of the ejector 8. A control part 14 detects the ozone concentration in the bath water flowing through the circulation passage 2 based on the input signals from the ozone sensor 3, and controls the operation of the ozonizer 12 based on the detection result.
