Select the appropriate faucet for the sink. There are basically two types: a center set faucet, which has handles that are part of the faucet assembly, or a wide spread faucet, in which the handles and the faucet are installed separately into predrilled holes in the sink or cabinet.

Close the water supply valves and turn on the existing faucet to clear the water lines. Then turn off the hot and cold water supplies with the handles that should be located on each pipe under the sink.

Disconnect the drain plug linkage and the hot and cold water supply lines.

Loosen the plastic nuts that hold the faucet in place by using a basin wrench. Lift the old faucet out.

Scrape away any remaining sealant by using a putty knife. Wash the area thoroughly with a damp towel in order to provide a clean seal for the new faucet.

Apply a bead of silicone caulking to the surface of the sink around the predrilled holes.

Slide on the gasket to the underside of the faucet and set it in place.

Thread the basin nuts on under the sink. Adjust and center the faucet from above, prior to tightening.

Apply Teflon tape to the threads of the tail pieces, then reconnect the hot and cold water supply lines.

Connect the drain plug linkage system and turn on the water supply.

Turn on the faucet to check for leaks.
