A one-piece overflow fitting is provided for a bathtub having a one piece overflow pipe. The one piece overflow pipe has an inverted L-shape having an elbow portion defining an upper end portion and a lower end portion. The upper end portion has an outer end defining an inlet adapted to fit through a bathtub overflow port. Threads are located on an outer surface of the upper end portion and surround the inlet. A lip extends radially outwardly from an outer surface of the overflow pipe between the elbow portion and the upper end portion to engage an outer surface of the bathtub end wall around the bathtub overflow port. A thin diaphragm is sealed to the outer end of the upper end portion to close the inlet to fluid flow.
