A drain for a prefabricated shower stall that can be quickly and easily connected to a drain pipe, even though the drain pipe might be off-center with respect to the shower drain opening. The drain consists of two interfitting parts, a first of which is a drain body designed for attachment to the shower stall, and the second of which is a bushing-like member designed to interconnect the drain body and drain pipe. The drain body has a round opening, with a converging wall, extending through it, and an outwardly extending flange by means of which it can be affixed to a prefabricated shower stall around the drain opening in the stall. The converging wall of the opening in the drain body serves as a seat for the second part of the drain, which has a frustoconical outer wall to make this possible. This second part has a cylindrical bore concentric with its outer wall and is of such size as to extend below the first part, when seated therein, and telescopically receive the drain pipe in its cylindrical bore. A prefabricated shower stall with the first part of the drain attached can be quickly installed in position over a standing drain pipe by applying suitable glue to appropriate surfaces of the involved parts and then seating the second part of the drain in the first part, while pushing it into telescoping interfit with the drain pipe.
