Abstract
Abstract A sink assembly of a type including an enclosing cabinet (14) for supporting a sink bowl (16) from a floor (24) includes a liquid-impervious cabinet liner (22) supported by the cabinet (14) within an enclosed space (32) below the sink bowl (16) and its drain pipe (20) for catching water dripping from leaks and condensations. The sink liner (22) communicates with a second drain pipe (52) which exhausts water from the sink liner (22). The sink liner (22) is constructed so that its drain pan (42) is raised above a cabinet floor (40), with the drain pan (42) having tapered surfaces for accelerating flow toward the second drain pipe (52).
