How To Install A New Bathroom Basin Faucet?

Bathroom Basin Faucet

Preparation and Tools

Before starting, gather necessary tools such as a wrench, screwdrivers (flathead and Phillips), plumber’s tape, and a rag. It’s essential to turn off the water supply valves under the sink or at the main water supply to prevent leaks and ensure safety.

Removing Old Faucet

Begin by disconnecting the water supply lines connected to the old faucet. Use a wrench to loosen and remove the nuts securing the faucet to the sink. Once disconnected, lift out the old faucet and any remaining parts. Clean the sink surface thoroughly with a rag to remove any debris or old plumber’s putty.

Preparing the New Faucet

Unbox the new faucet and verify all parts are included as per the manufacturer’s instructions. Before assembly, wrap the threads of the faucet stems or supply line connections with plumber’s tape. This helps create a tight seal and prevents leaks when connecting the water supply lines.

Mounting the Faucet

Position the new faucet correctly on the sink deck or countertop. Ensure the faucet is aligned with the pre-drilled holes or mark the location for drilling if necessary. Insert the faucet through the mounting holes, and from under the sink, secure it with the provided mounting hardware. Tighten the nuts or bolts with a wrench, being careful not to over-tighten, which could damage the faucet or sink.

Connecting Water Supply Lines

Connect the water supply lines to the corresponding hot and cold faucet stems. Hand-tighten the connections first, then use a wrench to snugly secure them. Double-check the connections for any signs of leaks before proceeding.

Checking for Leaks

Once the water supply lines are securely connected, slowly turn on the water supply valves. Check each connection point for leaks. If you notice any leaks, tighten the connections slightly until the leaks stop. Ensure the faucet handles are in the off position during this check to prevent accidental water flow.

Testing the Faucet

Test the functionality of the new faucet by turning the handles. Verify smooth water flow and easy adjustment of hot and cold temperatures. Check the aerator for any debris that may affect water flow and clean if necessary. Adjust the faucet position if needed to ensure comfortable use and proper alignment with the sink.

Installing Drain Stopper (if applicable)

If your new faucet includes a pop-up drain assembly, follow the manufacturer’s instructions to install it. This typically involves connecting the lift rod to the pop-up assembly under the sink and adjusting the rod length for proper operation. Test the drain stopper by pulling up and pushing down the lift rod to ensure it opens and closes smoothly.

Final Adjustments and Cleanup

Make any final adjustments to the faucet position or handle operation as needed. Remove any excess plumber’s tape or debris from the installation process. Wipe down the sink and faucet with a clean rag to remove fingerprints or water spots, leaving the installation area tidy and presentable.


Installing a new bathroom basin faucet requires careful preparation, step-by-step assembly, and thorough testing to ensure proper functionality and a leak-free installation. By following manufacturer instructions and using the right tools, you can successfully upgrade your bathroom’s aesthetics and functionality with a new, stylish faucet.
