• Silicone sealant – Optional, but helps to create a clean, watertight seal at the faucet base. 

Having these tools and materials ready before you begin will streamline the process and help you achieve professional results.

Shutting Off Water Supply and Preparing the Area 

Before starting your faucet replacement project, it’s crucial to properly shut off the water supply and prepare the area to prevent potential issues or damage. Follow these steps to ensure a smooth process: 

Step 1: Turn Off the Water 

Locate the shutoff valves connected to the bathtub supply lines. These are typically found near the base of the tub or within an access panel. Turn the valves clockwise to stop the water flow. If there are no individual shutoff valves, you will need to turn off the main water supply for your home. 

Step 2: Drain Excess Water 

Once the water is turned off, open the tub faucet to release any remaining water and pressure in the lines. This step will help minimize mess when you begin the replacement process. Place towels and a bucket under the faucet area to catch any drips or residual water that might escape during disassembly. 

Step 3: Clearing the Work Area 

Remove any toiletries, towels, or personal items around the bathtub to give yourself plenty of room to work. Ensure the area is clean and free of debris, as this will make the replacement process more efficient and reduce the risk of damage to the new faucet or existing fixtures.

Removing the Old Roman Tub Faucet 

Step 1: Remove the Faucet Handles 

Use an Allen wrench or a screwdriver to locate and remove the set screw on each handle. Once the screws are removed, gently pull the handles off and set them aside in a safe location to avoid losing any parts.

Step 2: Remove the Spout 

Inspect the spout to determine if a set screw secures it or if it is threaded. If the spout features a set screw, use an Allen wrench to loosen it, then lift the spout off the base. If the spout is threaded, twist it counterclockwise until it detaches completely. Take care to handle the spout gently to avoid unnecessary damage to surrounding fixtures.

Step 3: Disconnect the Water Supply Lines 

Locate the water supply lines beneath the tub and use an adjustable wrench to loosen the connections. Carefully detach the lines to stop water flow to the faucet. If the supply lines show signs of corrosion or wear, it is advisable to replace them to prevent future leaks or complications with the new installation.

Step 4: Remove the Valve Trim 

Unscrew the escutcheons and valve trim plates from the faucet assembly. If there is caulking around these components, use a utility knife to cut through it carefully, ensuring you do not damage the surrounding surfaces. Once free, remove all valve trim components and set them aside, leaving the area ready to install the new faucet.

How to Replace Roman Tub Faucet: Installing the New Roman Tub Faucet 

Step 1: Position the New Faucet 

Align the new spout and handles with the existing holes on the tub deck. Ensure the valves are correctly spaced to match the dimensions of the new faucet. Double-check the alignment to avoid any issues during the final installation process. This step ensures the new faucet assembly fits properly and functions. 

Step 2: Secure the Handles and Spout 

Place the escutcheons over the handles and spout base, then tighten them securely into position. Refer to the manufacturer’s instructions to confirm the correct installation process for your specific faucet model. If the spout has a set screw, use the appropriate tool to tighten it firmly. This step ensures that all components are properly secured and won’t shift or loosen over time. 

Step 3: Connect the Water Supply Lines 

Attach the hot and cold water supply lines to the corresponding valves. Make sure each connection is aligned correctly to prevent cross-connections. Apply plumber’s tape to all threaded fittings to create a watertight seal, reducing the risk of leaks. Use a wrench to tighten each connection; however, avoid over-tightening, which could damage the fittings. 

Step 4: Tighten and Check All Connections 

Before completing the installation, inspect all nuts, bolts, and connections to verify that they are securely fastened. Turn on the water supply and test the faucet by running both hot and cold water. Carefully check for any leaks around the connections or faucet components. If leaks are present, tighten the fittings further or reapply plumber’s tape as needed. After confirming everything is functioning properly, clean the area around the new faucet to complete the installation. 

Testing the New Faucet for Leaks

Step 1: Turn On the Water Supply 

Slowly turn the water back on to begin checking for leaks. Gradually increase the water pressure to ensure it flows smoothly through the system without causing unwanted strain on the connections. This step is crucial as sudden pressure surges could aggravate loose fittings or create leaks. 

Step 2: Test the Handles and Spout 

Open both the hot and cold water handles fully to test the water flow and verify the proper installation of the faucet. Observe the water coming out of the spout for consistent flow and adjust the handles to confirm smooth operation and reliable water temperature control. 

Step 3: Inspect for Leaks 

Carefully inspect the area under the tub and around the base of the faucet for any signs of water leakage. Pay close attention to seams, connection points, and areas where the faucet meets the sink or tub. If any leaks are detected, use a wrench to tighten the connections securely or reapply plumber’s tape to ensure a watertight seal. Testing thoroughly at this stage prevents future issues and ensures a successful installation. 

Final Touches and Cleanup 

Step 1: Seal the Base (If Needed) 

If the manufacturer recommends sealing, apply a thin bead of silicone sealant around the base of the spout and handles. This creates a watertight barrier to prevent moisture from seeping beneath the fittings, which could lead to damage over time. Use a wet finger or a tool to smooth the sealant for a neat finish. Before exposing it to water, allow the sealant to cure based on the product’s instructions. 

Step 2: Clean Up the Work Area 

With the faucet securely installed and tested, take time to clean up the work area. Carefully wipe down the tub deck, faucet, and surrounding surfaces to remove leftover debris, smudges, or fingerprints. Use a gentle cleaning solution if necessary, but avoid harsh chemicals that could damage the finish of your new faucet. A clean workspace enhances the appearance and ensures no leftover residue interferes with the faucet’s operation. 

Step 3: Dispose of the Old Faucet 

Properly dispose of your old faucet and any used materials or packaging. If the old faucet is made of recyclable metal, consider taking it to a recycling facility. Adhering to proper disposal methods helps the environment and ensures that your work area is left tidy and organized.
