Abstract: A device and method for the controlled release of a soapy water concentrate into a sink or basin for providing a sink full of soapy water for institutional pot, pan and dishwashing applications. The device is implemented as a container filled with semi-solid, water-soluble soap concentrate. The container has a base which allows it to freely stand at the bottom of the sink being filled with water. A stream of water from a sink faucet is directed into an inlet aperture on an upper surface of the container. The water enters the inlet aperture, commingling and interacting with the semi-solid soap to dissolve a fractional portion thereof and form a soapy water concentrate solution. The solution is ejected under pressure by the entering water out through a plurality of outlet apertures defined in the container, thereby filling the sink with soapy water concentrate.
