How to Install Bathroom Vanity Plumbing

Installing bathroom vanity plumbing is a relatively straightforward task that can be completed in a few hours with the right tools and materials. By following these step-by-step instructions, you can ensure that your vanity is properly plumbed and ready to use.

Materials you will need:

Vanity with pre-drilled holes for plumbing fixtures
Faucet
Drain assembly
P-trap
Supply lines (hot and cold)
Teflon tape
Plumber's putty
Adjustable wrench
Basin wrench
Screwdriver

Step 1: Prepare the vanity

Before you begin installing the plumbing, you need to prepare the vanity. This includes removing the drawers and doors, and placing the vanity in its final location. Once the vanity is in place, you can start installing the plumbing fixtures.

Step 2: Install the faucet

The first step is to install the faucet. Start by wrapping the threads of the faucet with Teflon tape. Then, screw the faucet into the pre-drilled holes in the vanity top. Be sure to tighten the faucet securely, but do not overtighten it.

Step 3: Install the drain assembly

The next step is to install the drain assembly. Start by applying a bead of plumber's putty around the base of the drain flange. Then, insert the drain flange into the drain hole in the vanity top. Be sure to press the flange firmly into place.

Next, attach the drain body to the drain flange. Be sure to tighten the connection securely.

Step 4: Install the P-trap

The P-trap is a curved pipe that connects the drain assembly to the drain pipe. Start by wrapping the threads of the P-trap with Teflon tape. Then, screw the P-trap onto the drain body. Be sure to tighten the connection securely.

Step 5: Connect the supply lines

The next step is to connect the supply lines to the faucet. Start by wrapping the threads of the supply lines with Teflon tape. Then, screw the supply lines onto the hot and cold water valves on the faucet. Be sure to tighten the connections securely.

Step 6: Test the plumbing

Once all of the plumbing fixtures are installed, it is important to test the plumbing to make sure that there are no leaks. Turn on the water supply and check for leaks around the faucet, drain, and supply lines. If you find any leaks, tighten the connections until the leak stops.

Once you have tested the plumbing and everything is working properly, you can re-install the drawers and doors on the vanity. Your bathroom vanity is now ready to use!
