Abstract
A shower or bathtub drain system (10,60) in which a sealing ring (16,16') is fastened to one end of a strainer body (32) or shoe (64) and inserted through the drain hole (14,58) in the bottom of the shower or bathtub from the space below the bottom surface. The sealing ring (16,16') is of a resilient material and has an upper flange (18,18') for overlapping the surfaces (20,62) at the edges of the drain hole. The installation is completed from the space above the bottom plate member (12,56) of the bathtub or shower by positioning a clamp ring (40,68) over the sealing ring flange (18,18') and then pulling the clamp ring (40,68) toward the strainer body (32) or shoe (64) by screw connectors (52,78) inserted through holes (48,80) in the clamp ring (40,68) and threaded in holes (50,76) in the strainer body (32) or shoe (64). As the clamp ring (40,48) is pulled toward the strainer body (32) or shoe (64) the sealing ring upper flange (18,18') is compressed between the clamp ring (40,68) and the bottom plate member (12,56) which seals the space between the surfaces (20,62) and the clamp ring (40,68).
