How to Replace a Faucet

Swap a kitchen or bathroom faucet yourself.

Replacing a faucet is a satisfying DIY upgrade. The work itself is simple; the awkward part is the cramped space under the sink, so good light and patience help more than any tool.

Shut off and disconnect

Close the supply valves under the sink and open the faucet to release pressure. Disconnect the supply lines and, on a sprayer or pull-down, the hose. A basin wrench reaches the hard-to-access mounting nuts up behind the sink.

Remove the old faucet

Undo the mounting nuts and lift the faucet out. Clean off old gunk and sealant from the sink deck so the new faucet seats cleanly.

Install the new one

Set the new faucet with its gasket or a bead of plumber's putty per the instructions, secure the mounting nuts, and connect the supply lines — often with new flexible supply hoses. Turn the water on slowly and check every connection for drips.

Frequently asked questions

Is replacing a faucet easy?

Yes, it's a manageable DIY job. The trickiest part is working in the tight space under the sink; a basin wrench helps reach the mounting and supply nuts.

Do I need a plumber to replace a faucet?

Usually not — most faucet swaps are DIY. Call a plumber if the shutoff valves are seized, the connections are corroded, or you find other problems under the sink.
