Step 3 · Install the New Bathroom Faucet

This is the step people usually slow down on. Go finger-tight first, then a quarter turn. No rush — replay the clip whenever it helps.

Apply plumber's putty to the base of the new faucet to create a watertight seal. Carefully install the new faucet, following the manufacturer's instructions. Secure it with the mounting nuts, tightening them firmly but gently to avoid damage. Connect the supply lines and tighten securely. Slowly turn the water supply back on and meticulously check all connections for any leaks.
