The liquid dispensing system comprises a household water system having an outlet, a storage unit for storing at least one liquid operatively connected to the household water system, and a control for connecting and disconnecting the storage unit to the household water system. In a first aspect of the invention the liquid is introduced into the household water system by a venturi. In a second aspect of the invention, the storage unit is positioned above an outlet of the household water system and is introduced by gravity. The control is normally biased to an “off” position. This invention can be utilized for showers, bathtubs, laundry tubs and sinks.
