How To Change A Bathtub Faucet
A bathtub faucet is more than just a water outlet — it defines the style, performance, and comfort of the bathroom. Over time, even the best faucets can develop leaks, corrosion, or reduced flow. Knowing how to change a bathtub faucet helps both homeowners and B2B installers maintain functional, modern bathrooms.
At DELICA Sanitary Ware, we design high-quality bathroom faucets that combine artistic design with reliable performance, making replacement and installation simpler, safer, and longer-lasting.
1. Preparing for Replacement
Before starting, make sure to turn off the water supply and gather the proper tools. Proper preparation ensures a clean and safe faucet replacement.
Tools and Materials Needed
| Item | Purpose |
|---|---|
| Adjustable wrench | Loosen and tighten fittings |
| Screwdriver | Remove faucet handles and trim |
| Plumber’s tape | Seal threaded joints to prevent leaks |
| Allen wrench | Remove handle screws |
| Towels and bucket | Collect residual water |
| Cleaning cloth | Wipe off debris and old sealant |
Tip: DELICA faucets come with installation kits that include washers, gaskets, and mounting hardware — saving installation time and ensuring a watertight seal.
2. Removing the Old Bathtub Faucet
Depending on the type of faucet (wall-mounted, spout, or shower-mixer combination), removal steps vary slightly. Follow the correct method for your faucet type.
Step 1: Shut Off the Water
Turn off both hot and cold water valves.
If you can’t find local valves, shut off the main home water supply.
Open the bathtub faucet to drain remaining water and relieve pressure.
Step 2: Remove the Faucet Handle
Use a screwdriver or Allen wrench to remove the small screw under or behind the handle.
Gently pull off the handle — avoid excessive force to prevent damaging the valve stem.
For two-handle systems, repeat for both handles.
Step 3: Detach the Spout
There are two main types of bathtub spouts:
| Type | How to Remove |
|---|---|
| Slip-on Spout | Loosen the set screw at the bottom with an Allen wrench, then slide off. |
| Threaded Spout | Turn counterclockwise to unscrew it from the wall pipe. Wrap the pipe with a towel to protect it during removal. |
Once removed, clean the threads and wall area from old putty or mineral deposits.
3. Installing the New Bathtub Faucet
DELICA recommends using faucets made from solid brass or stainless steel for their durability and corrosion resistance. Each faucet is designed for easy installation with precise threads and sealing gaskets.
Step 1: Prepare the Threads
Wrap plumber’s tape clockwise around the pipe threads (3–5 turns).
This prevents leaks and ensures a secure connection between the pipe and the new faucet.
Step 2: Attach the New Faucet
| Faucet Type | Installation Method |
|---|---|
| Threaded Spout | Screw the faucet onto the pipe clockwise by hand, then tighten gently with a wrench. |
| Slip-on Spout | Slide the faucet onto the pipe until it’s flush with the wall, then tighten the set screw underneath. |
Ensure the spout is straight and firmly seated against the wall. Avoid overtightening, as this may crack internal fittings.
Step 3: Install Handles and Trim
Align the handle stems with the valve cartridges and tighten screws.
Attach decorative escutcheons or trim plates for a clean, modern appearance.
Use silicone sealant around wall gaps if necessary to prevent moisture penetration.
4. Testing and Final Adjustments
Step 1: Turn the Water Back On
Slowly open the hot and cold valves or the main supply.
Turn on the faucet to test both hot and cold water flow.
Check for leaks at all joints and connections.
Step 2: Inspect Water Pressure
Ensure the water flow is consistent and balanced.
If the stream is uneven, remove the aerator or shower diverter and flush out trapped debris.
Step 3: Check the Diverter (if applicable)
If your faucet has a built-in shower diverter:
Pull up or press down the diverter knob.
Confirm water switches smoothly between the spout and showerhead.
DELICA’s diverters are tested for over 50,000 switching cycles to ensure lasting performance.
5. Common Problems and Solutions
| Problem | Possible Cause | Solution |
|---|---|---|
| Leak at base of spout | Loose connection or missing Teflon tape | Reapply tape and retighten spout |
| Low water pressure | Sediment in aerator or valve | Clean aerator and flush valve |
| Handle stiffness | Mineral buildup on cartridge | Remove handle, clean, and lubricate cartridge |
| Uneven temperature mix | Cartridge imbalance | Replace or recalibrate cartridge |
DELICA faucets use precision ceramic cartridges, ensuring drip-free performance and smooth handle movement.
6. Choosing the Right Replacement Faucet
When selecting a new bathtub faucet, consider both functionality and design. DELICA offers a wide range of styles to match modern, luxury, and minimalist bathrooms.
| Faucet Type | Features | Ideal For |
|---|---|---|
| Wall-Mounted Mixer Faucet | Combines hot/cold control and spout in one unit | Contemporary bathrooms |
| Two-Handle Faucet | Independent temperature control | Classic or traditional setups |
| Thermostatic Faucet | Maintains constant temperature | Luxury and hotel projects |

7. Maintenance Tips for Long-Term Use
To extend the life of your new bathtub faucet:
Clean regularly with mild soap and a soft cloth — avoid harsh chemicals.
Check for drips or loosened parts every six months.
Flush the aerator if water flow decreases.
Polish chrome or stainless surfaces to maintain shine.
For commercial or hotel installations, schedule annual cartridge inspections to ensure optimal water mixing.
DELICA’s premium faucets use PVD plating technology, offering extra resistance to corrosion, discoloration, and wear — ideal for long-term, high-frequency use.
