Abstract
Abstract The present invention provides a shower brush and liquid soap dispenser combination for use in a shower. The soap dispenser has an inlet end which is connectable to the main water supply of the shower and an outlet end which is connectable to the brush. The inlet end of the dispenser includes a venturi feed to a liquid soap container in the dispenser such that water flowing through the water supply and into the soap dispenser draws liquid soap by suction through the venturi feed from the liquid soap container. The liquid soap is mixed with the water to form a soap and water mixture which is then fed by the water supply through the dispenser to the brush.
