Step 4 · Install the Main Drain (P-Trap) Cover

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.

Take the largest piece of the trimmed shield, which is designed for the P-trap. Perform a dry fit by wrapping it around the P-trap and drain assembly to check your cuts. Once you confirm the fit, wrap it securely. Align the hook-and-loop fastener strips (e.g., Velcro®) with each other and press them firmly together along their entire length. Ensure the cover is snug and covers the entire trap assembly, from the drain tailpiece connection down through the U-bend and back to the trap arm entering the wall.
