Abstract: A mock shower drain for temporary, in-situ installation within a shower area that is configured to utilize an integrated bonding flange drain, the mock shower drain includes a lower section operable to mate with a drain fitting installed in the shower area, the drain fitting operable to mate with a corresponding lower section of an integrated bonding flange drain. An upper section is sized to fit within a cavity formed in a subfloor of the shower area sized to receive a corresponding section of the integrated bonding flange drain. A cap section is coupled to the upper section, the cap section forming a barrier to resist passage of debris to the drain fitting. An intermediate section intercouples the upper section and the cap section. The mock drain is dimensioned such that an uppermost portion of the mock drain is elevated at least as high as to be substantially flush with the subfloor of the shower area when the lower section of the mock drain is mated with the drain fitting.
