How to Fix a Leaking or Dripping Bathroom Vanity Faucet


Leaking or dripping bathroom vanity faucet is a common problem. It is not only an eyesore, but it also wastes a lot of water and can lead to costly water bills. Fortunately, this problem can usually be fixed relatively easily. There are several steps you can take to repair a leaking or dripping bathroom vanity faucet.

Identify the Problem

The first step in repairing a leaking or dripping bathroom vanity faucet is to identify the problem. There are several potential causes for a leaking or dripping faucet. The most common causes are a worn-out washer, a loose connection, a broken valve stem, or a corroded valve seat.

Gather the Necessary Tools and Materials

Once you have identified the problem, the next step is to gather the necessary tools and materials. You will need a flathead screwdriver, an adjustable wrench, a pair of pliers, a replacement washer, and a tube of plumber’s putty.

Disassemble the Faucet

The next step is to disassemble the faucet. Start by turning off the water supply to the faucet. Then, using the flathead screwdriver, remove the faucet handle. Once the handle is removed, you will be able to access the valve stem. Use the adjustable wrench to unscrew the nut that holds the valve stem in place. Then, use the pliers to remove the valve stem from the faucet.

Replace the Washer

Once the valve stem has been removed, you will be able to access the washer. If the washer is worn or damaged, you should replace it with a new one. To do this, simply unscrew the old washer and replace it with the new one. Make sure the new washer is properly seated and tight.

Reassemble the Faucet

Once the new washer is in place, you can begin to reassemble the faucet. Start by replacing the valve stem and securing it with the nut. Then, replace the faucet handle. Finally, apply a small amount of plumber’s putty around the base of the faucet and tighten the screws.

Test the Faucet

Once the faucet is reassembled, the final step is to test it. Turn on the water supply and check for any leaks or drips. If the faucet is working properly, you should be good to go. If not, you may need to repeat the steps above.


Leaking or dripping bathroom vanity faucets can be annoying and costly. Fortunately, they are usually relatively easy to fix. All you need is the right tools and materials, and a bit of patience. With a few simple steps, you can repair your leaking or dripping bathroom vanity faucet and save yourself money in the long run.
