How to Fix a Leaky Single-Handle Bathroom Faucet

A leaky bathroom faucet can be a frustrating problem, but it's one that can be easily fixed with a few simple tools and some basic plumbing knowledge. In this guide, we'll walk you through the step-by-step process of how to fix a leaky single-handle bathroom faucet.

Identifying the Leak

The first step is to identify the source of the leak. Check the base of the faucet, the handle, and the spout for any visible leaks. If you see water dripping from any of these areas, you've found the source of the leak.

Gathering Tools and Materials

Once you've identified the source of the leak, you'll need to gather the following tools and materials:

  • Adjustable wrench
  • Phillips screwdriver
  • Hex key (if necessary)
  • Replacement O-rings or washers (if necessary)
  • Plumber's putty (optional)

Fixing the Leak

The steps to fix a leaky single-handle bathroom faucet will vary depending on the source of the leak. Here are the most common types of leaks and how to fix them:

  3. Remove the faucet and replace the O-ring with a new one.
  4. Reinstall the faucet and tighten the nut.

Leaking from the Handle

  3. Remove the cartridge and replace it with a new one.
