Steps to Replace a Bathroom Faucet

Here we will explain the simple steps for a beginner to follow and replace the faucet with minimal plumbing tools.

1.      Turn off the Supply Line

When you start plumbing work at your home, start by turning off the water supply. Because when the water supply is on, it will not only disturb your plumbing work, but the water bill will also destroy your financial plans. 

It is smart to turn off the water supply of only that part of the home where you plan plumbing work. If you do not have a dedicated valve to shut off the supply of that part, you should turn off the main water supply and turn it on once you complete the plumbing work.

2.      Remove the Supply Lines

After you turn off the water supply, you must remove both the hot and cold supply lines. You can find these supply lines underneath the sink. You can use an adjustable wrench to do the job. 

When you remove the supply lines, there might be a small quantity of water in them. Therefore, you should keep a towel and bucket to capture water from the pipes.

3.      Remove the Old Faucet

Before you go on to replace a bathroom faucet, you will need to remove the old faucet. All faucets are placed in the sink in different ways. Some have a long locknut from the underside of the sink, while others have a threaded rod with a nut fitting it to a mounting plate on the underside of the sink.

From the underside of the sink, you will need to loosen the nut that holds the faucet to the sink. Once you loosen the nuts, you can remove the old faucet easily by moving it upwards from the sink.

4.      Preparation before Installation

Dirt and minerals can deposit on the surface over the years. Before installing the new faucet, scrub away the dirt and minerals. Afterward, you can attach the supply lines, and some of the faucets also come with the supply lines. 

5.      Install the Deck Plate

Some of the faucets come with a deck plate, but most do not. Therefore, convert a three-hole sink to a one-hole sink with a deck plate. It is beneficial to put a thin layer of plumber’s putty on the plate before the installation.

6.      Install the New Faucet

You will begin by putting the faucet into the deck plate or sinkholes. Make sure the supply lines are already connected. First, place the rubber washer, followed by the brass washers and the threaded screws. 

Tighten these screws using a screwdriver or screw tightener. These steps are simple to follow while performing the faucet replacement process.

7.      Connect the Water Supply Lines

Now you should connect the supply lines of both the hot and cold water supplies. When the water supplies are connected and the faucet is well-fitted into the assembly, you have completed the installation process. All you need to do is to test the installation process.

8.      Open the Water Supply

Any installation process is incomplete without due validation, which is possible through testing. When you install a bathroom faucet, the test you can perform is to open the water supply and check if the tap is running well and if there aren’t any leakages. 

If there is a leakage, you should tighten the screws and check the washers. If there is no leakage and the faucet is running well, you successfully complete the installation process.


It is essential to replace a bathroom faucet when it starts leaking water. Some other conditions can also drive you to change your bathroom faucet. However, the important thing is the installation process. Luckily, it is not difficult to replace a tap, and anyone, after reading the above instructions, can do it.
