Over time, even the most durable bathtub shower faucet can show signs of wear — dripping handles, corroded finishes, or outdated designs. Removing the old faucet is the first step toward upgrading your bathroom with a new, efficient model.
At Global Emysa, we design and manufacture long-lasting brass, stainless-steel, and ABS shower systems, all engineered for easy maintenance and installation.
This guide explains how to safely and correctly remove a bathtub shower faucet without damaging existing plumbing or wall surfaces.
Before beginning, ensure the main water supply is completely turned off. Open the faucet handles to release any pressure remaining in the lines.
Place a bucket and towel in the tub to catch residual water and protect surfaces.
Tools You’ll Need:
Adjustable wrench or basin wrench
Screwdrivers (flathead and Phillips)
Utility knife or putty scraper
Pliers
Silicone sealant remover or mild cleaner
Plumber’s tape (for reinstallation later)
Having the right tools ready saves time and prevents accidental scratches or leaks during removal.
Most bathtub shower faucets have visible handles and decorative trim plates.
Locate the handle screw — usually hidden under a small cap or logo on the knob.
Remove the screw using the correct screwdriver and gently pull off the handle.
Use a utility knife to cut through any old silicone sealant around the trim plate.
Carefully lift the plate away from the wall to reveal the valve body.
Set aside the trim components in order — they may help you identify the faucet model if replacements are needed.
The tub spout is often threaded or slip-fit onto a copper pipe.
For threaded spouts, use a wrench wrapped in a soft cloth to prevent finish damage. Turn counterclockwise until the spout loosens.
For slip-fit spouts, locate the small set screw underneath, loosen it with an Allen key, and slide the spout off.
Check the pipe for corrosion or mineral buildup and clean it gently with a cloth.
Unscrew the shower head from the arm by turning counterclockwise.
Use an adjustable wrench to remove the shower arm from the wall fitting.
Wipe off any remaining plumber’s tape or debris from the threads.
If you plan to reuse the arm or head, store them safely to avoid scratching or bending.
Behind the trim plate lies the most important component — the faucet mixing valve.
If the wall is tiled, you may need to remove a small access panel from the opposite side of the wall or cut a minimal service opening.
Loosen the mounting screws or clips holding the valve in place.
Use pliers or a wrench to disconnect the hot and cold supply lines.
Detach the tub and shower outlet pipes.
Once all lines are free, pull the valve straight out. Be cautious not to twist or bend the connected copper or PEX tubing.
Before installing a new faucet, inspect the area for:
Water damage or mold behind the wall.
Corroded fittings or mineral deposits on pipe threads.
Loose or worn mounting brackets.
Clean all surfaces thoroughly. Removing residue ensures proper sealing and alignment when fitting the new faucet assembly.
Always label or photograph connections before removal if you’re replacing a concealed thermostatic valve.
Replace worn gaskets and O-rings to prevent leaks when reassembling.
Use brass or stainless-steel fittings for long-term corrosion resistance.
If unsure about internal valve compatibility, consult your new faucet manufacturer for model-specific installation dimensions.
Removing a bathtub shower faucet may seem complex, but with patience and the right tools, it’s a manageable task that prepares your bathroom for a modern upgrade. By following each step carefully, you can avoid leaks and damage while ensuring a clean installation area.
