Step 4 · Install New Hardware and Test for Leaks

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.

Install the new shower handle(s), escutcheon plate, showerhead, and tub spout. Slowly turn the water supply back on, checking carefully for any leaks around the valve and connections. Adjust the temperature if needed. If leaks persist, carefully re-check all connections and tighten as necessary.
