VIDEO: How to Install A Bathroom Faucet
Updated: Mar 15
Installing a bathroom faucet is a lot simpler than you may think. Even if you have never installed a faucet before, you will be able to tackle the project with some common tools. It should usually take no more than one hour, and the installation method is fundamentally similar for almost every type of bath faucet in the market.
In this article, we are going to break down the process of installing a bathroom faucet using a Koozzo single handle faucet as an example.
Tools: an adjustable wrench, a bucket, a putty knife, rags
Optional: sealant or plumber’s putty, pipe joint compound
Place a container under the sink and turn off the water valves to relieve the pressure that is left inside the faucet lines. Using an adjustable wrench, unscrew the lines and drain the remaining water. If necessary, unscrew the line from the bottom of the faucet if there is not enough space for you to work around.
Many faucets may have a standard pop-up drain that requires a lifting rod. To disconnect the drain, unscrew the mounting nuts with your hands and unclip the lifting rod from the mechanical pop-up. You will then be able to unscrew and remove the extension rod.
Remove the old faucet.
Take the rubber washer, steel washer, clamp, and nuts off the faucet. Install the gasket. If your faucet does not come with a gasket, then you may need to use sealant or plumber’s putty to help secure the faucet. Apply a thin layer of sealant or putty to the bottom of the faucet before putting in the faucet.
Please note that even though the plumber’s putty is useful, it should not be used with plastic or granite, as it might leave a stain.
Clean the area where the new faucet will go and insert the new faucet. Set the pipes and the faucet into the mounting hole(s). If the previous faucet required three holes, use a deck plate and align the faucet.
Once the faucet is in the mounting hole(s), place the rubber washer, steel washer, and the clamp with nuts back on the faucets. Check the alignment of the faucet, twist the nuts, and then tighten with an adjustable wrench.
Connect the hot and cold water supply lines. Normally, the red supply line will connect to the left for hot water and the blue supply line will connect to the right for cold water. If you are working with limited space, you can loop the supply lines for a better fit under the sink but make sure there are not any kinks.
