SOLUTION: The bathtub water/rainwater reutilizing system is provided with a water storage tank for storing bathtub water or rainwater, a water feeding means for feeding the water in the water storage tank to apparatuses reutilizing bathtub water or rainwater, a purifying section for purifying bathtub water or rainwater, and a recirculating means for conveying the bathtub water or rainwater once fed to the water storage tank via the purifying section to the purifying section again. The recirculating means is operated to repurify the bathtub water or rainwater according to the water temperature measured by a water temperature measuring means provided at one or more places on feed water paths to the apparatuses reutilizing the bathtub water or rainwater from the water storage tank or in the water storage tank or in the purifying section.
