A fluid treatment and disposal system includes a sink, having a basin, a sink drain inlet, and a sink drain trap. An open cavity is disposed behind a rearward wall of the sink basin, between a top portion of the sink and the sink drain trap. A curved transition surface receives fluid entering the sink. Embodiments of the drain are shaped to promote the evacuation of fluid from the basin while limiting turbulence. An exhaust port fluidly coupled with the open cavity evacuates the open cavity and surrounding environment. Embodiments optionally associate one or more of the following with the open cavity: Ultra-Violet (UV) Germicidal Lights, and Ozone water, copper-silver ionization, and/or sanitizing agent injection systems.

A sink includes a front wall, a first side wall, and a second side wall. The front wall includes an inner surface that defines part of a basin of the sink, and an outer surface located opposite the inner surface that is configured to be exposed in front of an opening of a cabinet in which the sink is installed. The front wall includes first and second lateral portions that extend outwardly past the first and second side walls. The first and second lateral portions of the front wall are configured to at least partially overlap a front face of the cabinet adjacent the opening, so as to substantially conceal the opening when the sink is installed thereto.

Disclosed is a method for water saving by retrofitting an institutional plumbing fixture having a combination of an integral lavatory basin and a toilet bowel integrally attached thereto by inserting into the fixture a urinal-type collection receptacle having a water inlet opening on its top side and a water outlet opening on its bottom side; and fluidly interposing the receptacle via the inlet and outlet openings between the lavatory drain pipe and the drain trap provided for the plumbing fixture. Also disclosed is an institutional plumbing fixture retrofit for water saving, and a retrofit urinal-type receptacle.
