Abstract: A shower drain connector is provided having a vertical guide terminating at an upper end by a radial installation flange. The vertical guide forms a collar sleeve adapted to receive a drainage pipe in a contained manner. The collar sleeve has an inner diameter that larger than the outer diameter of a drain pipe being contained. The radial installation flange is less than or equal to 16 inches in diameter. A plurality attachment orifices adapted form connectors for receiving standard screw connectors positioned evenly radially about a periphery of the upper flange to allow for attachment of the flange to a subfloor such as to maintain a perfectly centered support for the drainpipe in spite of any on-site conditions.
