Hand-held shower system with inline adjustable temperature/pressure balanced mixing valve

A bathtub-mounted hand held shower system controlled by a single valve without the need of a diverter, comprising:

• a bathtub;
• a hot water supply connected to the bathtub;
• a cold water supply connected to the bathtub;
• a spigot connected to the bathtub;
• hot and cold spigot valves connected between the spigot and the respective hot and cold water supplies;
• a pressure balanced valve connected to the bathtub and connected in hydraulic communication with the respective hot and cold water sources;
• a hand held shower head;
• and
• a flexible hose hydraulically connecting the hand held shower head to the pressure balanced valve;
• wherein the hand held shower head may be actuated independently of the hot and cold spigot valves to actuate a flow of water of characterized by a substantially predetermined temperature and pressure.

A method for controlling the water temperature and pressure output from a hand held shower head, comprising the steps of:

• a) connecting a pressure balanced valve having an output and a plurality of inputs to a bathtub deck;
• b) hydraulically connecting the pressure balanced valve output to the hand held shower head;
• c) hydraulically connecting a hot water source and a cold water source to respective pressure balanced valve inputs;
• and
• d) controlledly opening the pressure balanced valve to achieve a water output from the hand held shower characterized by a predetermined pressure and temperature.
