    Upgrading your bathroom vanity, countertop surface, sink, and faucet is one of the best home repair upgrades in which you can invest. Removing an old bathroom vanity and installing a new stylish vanity will remake your bathroom.

    In the process, you will be installing a new faucet. In this tutorial, I will provide you a photo-rich visual guide to installing a new 4" centerset single-handle cartridge faucet in a new vanity top. The single handle cartridge faucet is a popular choice for kitchen and baths and comes in a seemingly endless variety of styles.

    This tutorial shows a trick installation of the faucet into a new vanity top, in this case, a granite top with an undermount sink. The "trick" is to flip the vanity top upside down and make all the connections of the faucet to the top before the top is installed into the vanity. This makes the faucet installation very easy.

    Needed Tools and Materials:

    • Plumber's putty or silicone caulk (and rubbing alcohol for clean up)
    • Phillips head screwdriver
    • Adjustable wrenches (2)
    • Basin wrench (if installing faucet with vanity top already installed)
    • Water supply lines
