How To Install A Bathtub Shower Faucet
Over time, your bathtub shower faucet may start to leak, corrode, or lose efficiency due to mineral buildup. Whether you’re planning to repair it, replace it with a new model, or upgrade to a more modern system, knowing how to remove the old faucet properly is essential.
1. Tools and Materials You’ll Need
| Tool / Material | Purpose |
|---|---|
| Adjustable wrench | Loosen nuts and fittings |
| Allen wrench or screwdriver | Remove handle screws |
| Utility knife or putty scraper | Remove old sealant |
| Penetrating oil | Loosen corroded parts |
| Teflon tape | Prepare threads for reinstallation |
| Towels and bucket | Catch dripping water |
| New faucet assembly (optional) | Replacement part |
Faucets from KPTOPSHINE are designed for easy installation and removal — often using universal connection fittings and anti-corrosion finishes that make maintenance easier.
2. Preparation Steps
Turn Off the Water Supply
Locate the main shut-off valve or bathroom supply valves.
Turn them clockwise to stop water flow to the shower.
Open the faucet handles to release any remaining pressure.
Protect the Work Area
Place towels or a rubber mat in the bathtub to prevent scratches.
Keep a small bucket nearby to catch any residual water.
Inspect the Faucet Type
Determine what kind of faucet you have before disassembly:
| Faucet Type | Common Structure | Removal Difficulty |
|---|---|---|
| Single-handle mixer | One lever, built-in diverter | Easy |
| Two-handle setup | Separate hot/cold controls | Moderate |
| Concealed Shower Mixer | Hidden behind wall plate | Complex (requires care) |
Most modern faucets — including those by KPTOPSHINE — feature ceramic cartridges and contemporary single-handle designs, making maintenance much simpler.
3. Removing the Faucet Handle
Step 1: Locate the Handle Screw
Most faucet handles have a small cap covering the screw.
Pry the cap gently with a flathead screwdriver.
Step 2: Unscrew and Remove the Handle
Use a screwdriver or Allen wrench to remove the handle screw.
Pull the handle straight off the valve stem — avoid twisting too hard.
Step 3: Remove Decorative Trim Plate
Unscrew or pry off the trim plate (escutcheon) surrounding the valve.
Use a utility knife to cut through any silicone sealant around it.
Set the plate aside safely.
4. Disconnecting the Faucet Components
Step 1: Remove the Spout
Look under the bathtub spout for a set screw (common in slip-fit spouts).
Loosen it with an Allen key, then slide the spout straight off the pipe.
For threaded spouts, twist counterclockwise to unscrew it.
Step 2: Remove the Shower Arm and Head
Unscrew the showerhead from the shower arm.
Use a wrench to remove the shower arm from the wall outlet.
Clean any debris or old Teflon tape from the threads.
Step 3: Access the Valve Assembly
The valve body (behind the wall) controls water mixing.
If you’re replacing the valve, remove the retaining nuts with a wrench.
Disconnect the hot and cold water lines carefully to avoid damaging the pipes.
KPTOPSHINE’s concealed shower systems use precision-machined brass valves with standardized inlets, making disassembly and replacement easier without damaging wall tiles.
5. Cleaning and Preparing for Installation
After removing all parts:
Wipe the area with a clean, dry cloth.
Remove any old sealant, mineral deposits, or corrosion around the openings.
Inspect pipes and connectors — replace any parts showing rust or cracks.
Apply penetrating oil to stubborn fittings and allow a few minutes before attempting removal.
6. Optional: Installing a New Faucet
If you’re upgrading your system:
Wrap Teflon tape around all male threads.
Mount the new mixer valve using the same alignment as the old one.
Connect water lines and outlets using adjustable wrenches.
Test for leaks before closing up the wall or sealing trim.
Faucets from KPTOPSHINE are engineered for tool-friendly installation, with anti-leak cartridges and durable brass fittings suitable for both residential and hotel applications.
7. Safety and Maintenance Tips
Always verify that water is fully turned off before loosening fittings.
Avoid overtightening — excessive torque may crack fittings or damage seals.
Use only plumber-approved sealants and Teflon tape.
After installation, flush the valve to remove debris before final assembly.
Regularly clean and descale components to extend faucet life.
