You’ll need a basin wrench, adjustable wrench, plumber’s putty, and a new faucet.
Locate the shut-off valves under the sink and turn them off.
Use the basin wrench to loosen the nuts holding the old faucet in place.
Clean any old putty or debris from the sink surface.
Place the new faucet in the mounting holes and secure it with nuts.
Attach the water supply lines to the new faucet and tighten them with an adjustable wrench.
Turn the water supply back on and check for any leaks.
Your new kitchen faucet is now installed and ready to use!
