Claim 4:
5. An assembly for placement in a sink or bathtub having one or more basins having a drain comprising:
a passageway defined by an adapter through which, when the assembly is in use in a basin, fluid in the basin is able to flow toward the drain;
a structure in fluid communication with and upstream of the passageway operable between open and closed positions selectively blocking the passageway when in a closed position and not blocking the passageway when in an open position, such that fluid in a basin is able to flow through the passageway when the structure is in the open position but not when the structure is in the closed position,
wherein an inlet of the structure is provided on a first side of the structure, and wherein an outlet of the structure is provided on a second side of the structure opposite the first side and directs fluid into the adapter;
wherein the adapter mates with the basin drain to prevent fluid in the basin from escaping into the drain other than through the structure;

an actuator controlling the position of the structure between the closed position and the open position; and
a processor configured to send commands for controlling the actuator, such that in response to the commands from the processor, the actuator opens or closes the drain valve such that the assembly is capable of automatically draining the basin;
wherein the processor is in communication with a water valve operable between open and closed conditions to selectively deliver water to the basin; and, wherein the processor is configured to:
receive input from a temperature sensor, a cleanliness sensor, and a liquid level sensor; and
send commands for controlling the actuator and/or the water valve such that in response to the commands from the processor, the actuator opens or closes the drain valve and/or the water valve open or close such that the assembly is capable of automatically filling and draining the basin to maintain a desired range of concentrations of a fluid comprising one or more of water, soap, and sanitizer, and to maintain the fluid in each basin at a desired amount or height and within a desired range of temperature.
