A simplified diaphragm pressure balancing valve assembly is claimed with a body having inlet and outlet water ports selectively connected to supply a shower or a spout. The body includes a cylindrical opening to receive a cartridge assembly including inlet and outlet parts for alignment with the inlet and outlet ports of the body. A compact stationary pressure balancing device is provided, to avoid scalding of a bather, which remains stationary when the valve is operated. The assembly includes a disc assembly which is selectively moveable in relation to each of the sealed hot and cold water outlet ports, allowing water to pass out of the cartridge, exiting the valve to a spout or a shower. Supplementary members of the housing, for example a trim nut and body nut, are provided to ensure a press fit between the members and the disc.
