How to Install a Three Knob Tub Faucet

A three-knob tub faucet is a classic shower fixture with a handle for hot, cold and the tub or shower diverter. This fixture installs on the shower plumbing using a special body valve that has three outlets. The middle outlet is for the diverter and the two outlets on each end are for the hot and cold water. Before you install the shower, this valve must be installed on your plumbing by a professional plumber.
