Step 2 · Remove the Shower Handle
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.
Remove your existing shower handle. For a single-handle Delta faucet, locate the setscrew (often under a cap). Use an Allen wrench to remove the setscrew, then carefully pull the handle off. If the setscrew is stubborn, consult alternative methods in the linked videos.
