Locate the water shut-off valve for the shower. This might be an isolation valve located near the shower itself. If you cannot find a dedicated isolation valve, you will need to turn off the main water supply to the entire house using the main stopcock. It is critical to ensure the water is completely off before proceeding.

Goal: Shut off water to the shower

  • If you shut off the main stopcock, make sure no one else in the house needs to use the water while you are working.

FAQs

What should I do if my shower head or handle screws are stuck or corroded?

For a stuck shower head, apply penetrating oil and let it sit for 15-30 minutes before trying the adjustable wrench again. For corroded or stubborn handle screws, you can try placing a rubber band over the screw head for better grip with your screwdriver, or consider a screw extractor tool if they are stripped. Always apply gentle, steady pressure to avoid further damage.

How can I be sure the water is completely off before I start working?

After turning off the shut-off valves, turn on the shower faucet to verify that the water flow stops completely. If there's still a drip or trickle, the valves might not be fully closed, or you may need to locate and turn off the main house water supply. It's crucial to confirm no water is flowing before proceeding to prevent unexpected leaks.

What are the most common mistakes beginners make during this project, and how can I avoid them?

A common mistake is not protecting the drain, which can lead to losing small screws or parts. Another is forcing stuck components, which can damage plumbing or finishes. Always cover the drain, use penetrating oil for stuck items, and wrap wrench jaws with tape or a cloth to prevent scratching chrome finishes.

My shower handles don't have visible screws or decorative caps. How do I remove them?

Some shower handles have a small set screw located on the underside or neck of the handle, usually requiring an Allen wrench (hex key) to loosen. Others might be a push-on style that can be gently pried off with a flathead screwdriver (protected by tape) or a putty knife, revealing the main handle screw underneath.

and buy a new unit to attach to the wall. The first thing to do is find the isolation valve that cuts the water supply to the shower and turn off. You don't want water pumping out all of you when you take the unit off the wall. If you can't find the isolation valve because it's hidden under the bath or something like that, your second option is to turn off the main stock cock in the house, but make sure nobody else needs the water supply while you're doing the work. Otherwise, you've got it. Before we take the unit off the wall, I'm going to disconnect the shower hose and
