How To Install A Bathtub Shower Faucet

Installing a Bathtub Shower Faucet requires careful preparation, correct connections, and proper sealing to ensure smooth operation and no leaks. This guide explains how to install a bathtub shower faucet step by step and can be applied to Funjay Sanitary products, known for precision-engineered bathroom fixtures and durable finishes.

1. Tools and Materials Required

• Adjustable wrench

• Pipe wrench

• Screwdrivers (flat and Phillips)

• Allen wrench (for handle set screws)

• Teflon tape or thread sealant

• Silicone caulk or plumber’s putty

• Pipe cutter or hacksaw

• Level and measuring tape

• Soft cloth for protection

2. Preparation

1. Turn off the water supply to the bathroom or the entire house.

2. Open the old faucet to relieve water pressure.

3. Cover the drain with a cloth to prevent small parts from falling in.

4. If you are replacing an old system, remove the decorative trim and cut open the wall for access to the valve and pipe connections.

3. Remove the Existing Faucet Assembly

1. Remove the old showerhead by unscrewing it from the shower arm.

2. Detach the handle and trim using a screwdriver or hex wrench.

3. Unscrew or pull off the tub spout, depending on whether it is a threaded or slip-fit design.

4. If replacing the mixing valve, cut and remove the old valve carefully, keeping the hot and cold supply pipes intact.

5. Clean all threaded connections and remove any remaining sealant.

4. Install the New Mixing Valve

1. Position the new valve at the correct height—about 30–40 cm above the tub rim is standard.

2. Secure it to a wood backing or bracket behind the wall to keep it stable.

3. Connect the water supply lines to the valve’s inlets (hot on the left, cold on the right).

4. Connect the outlet pipes:

• The top outlet goes to the showerhead.

• The bottom outlet connects to the tub spout.

5. Use Teflon tape or thread sealant on all threaded joints.

6. Tighten with a wrench, ensuring all fittings are secure but not over-tightened.

5. Check for Leaks

1. Turn on the main water supply.

2. Slowly open the valve and check each connection for any leaks.

3. If a leak appears, tighten the joint or reapply thread sealant before closing the wall.

6. Install the Tub Spout

1. Threaded spout: Wrap the pipe threads with Teflon tape, then screw the spout onto the pipe until tight and level.

2. Slip-fit spout: Slide it onto the copper pipe and tighten the set screw underneath.

3. Apply a thin bead of silicone caulk around the base where the spout meets the wall for a watertight seal.

7. Install the Showerhead

1. Wrap the shower arm threads with Teflon tape.

2. Screw the showerhead onto the arm and tighten by hand.

3. Wipe the surface clean with a soft cloth to avoid scratching the finish.

8. Attach Trim and Handle

1. Place the escutcheon plate (trim) over the valve and secure it with screws.

2. Attach the handle using a screw or set screw, aligning it properly with the valve stem.

3. If your faucet includes a diverter function, test to ensure smooth switching between tub and shower.

9. Final Testing

1. Turn on the faucet and run water at both hot and cold settings.

2. Check that the flow rate is stable and there are no leaks around connections or trim.

3. Seal around trim plates and wall openings with clear silicone if necessary.

4. Allow the caulk to cure fully before using the shower.

10. Maintenance Tips

• Clean the faucet regularly using mild soap and water; avoid abrasive cleaners.

• Inspect seals and joints annually to prevent hidden leaks.

• If water pressure decreases, remove the showerhead and rinse the aerator to remove mineral buildup.

• Apply new silicone sealant when replacing tiles or trims.
