The toilet water tank receives water from a water supply system and toilet cleanser from the refillable container and has a float valve controlling water inflow and toilet cleanser inflow so that, the liquid level in the water tank being lower than a predetermined level, water and toilet cleanser flow into the water tank, mixing with the liquid in the water tank and, the liquid level being above a predetermined level, inflow of water and toilet cleanser is stopped. A dose regulator provides a predetermined flow rate of toilet cleanser. The incoming water having a predetermined water flow rate and the incoming toilet cleanser having a predetermined flow rate, a predetermined ratio of toilet cleanser to water is maintained in the water tank.
