Installing a bathroom faucet is actually quite simple, especially since manufacturers are continually making things easier for the homeowner who wants to save money and avoid hiring a professional.

NOTE: These are general installation instructions, always refer to the manufacturer instructions as they could vary depending on the complexity and functionality of the product.


Step by Step Instructions

Step 1

Remove the old faucet. Turn off the water supply, turn the faucet handles to release any pressure and water that may be trapped in the lines, and disconnect the water supply lines.


Step 2
Remove the old flange.

Step 3

Put the new flange into place. Apply a ring of plumber’s putty on the spout base (or around the escutcheon if one is included) for a watertight seal. Press gently into place.


Step 4

Attach the faucet spout. Beneath the counter, tighten the brass nut provided. Scrape away any excess plumber’s putty at the spout base.


Step 5

Install faucet handles. Attach the water supply lines (remember that left is hot water, and right is cold), and put the handles into place. Tighten the faucet spouts under the counter using the brass nuts provided.


Step 6

Complete water supply lines. Attach the brass T to the threaded spout pipe. Connect the hot and cold hoses to the brass T. Connect your water supply lines, using a strip of Teflon tape for a leak-free connection.


Step 7

Using a rope of plumber’s putty, install new drain flange to the pop-up assembly.

Step 8

Connect P-trap to the pop-up and drain pipe.


Step 9

Connect the pivot rod to the pop-up and adjust to the height you want.
