Step 1 · Shut Off Water Supply and Prepare Work Area

The most critical first step is to completely shut off the water supply to the shower. Locate the main water shut-off valve for your house, which is often in the basement, a crawl space, or a utility closet. Turn the valve clockwise until it is fully closed. If your shower has dedicated shut-off valves (sometimes accessible via a panel behind the shower), you can use those instead. After closing the valve, turn the shower handle on to confirm that the water flow has stopped and to relieve any pressure in the lines. Place a rag or drain cover over the shower drain to prevent losing any small parts.
