Changing your sink faucet might sound like a job for a plumber, but with a little patience, the right tools, and guidance, you can do it yourself and even enjoy the process. As a home décor enthusiast who’s handled countless DIY faucet replacement projects, I’ve learned that updating your faucet isn’t just about fixing a leak; it’s about giving your kitchen or bathroom a fresh, modern touch.

Whether you want to replace a bathroom sink faucet for a style upgrade or just need to stop that constant drip, this guide will show you how to change sink faucet step-by-step safely, confidently, and like a pro.

Before You Begin: Tools and Materials You’ll Need

Every successful DIY project starts with preparation. Here’s a quick checklist of the tools needed to change a sink faucet before you start unscrewing anything:

• Adjustable wrench or basin wrench
• Plumber’s tape (Teflon tape)
• Bucket or towel (to catch excess water)
• Silicone sealant (optional)
• Flashlight
• New faucet and supply lines

Pro Tip: Always turn off the water supply before starting. It sounds obvious, but trust me many DIYers (including my younger self!) learn this lesson the hard way.

Shut Off the Water Supply

Let’s start your DIY faucet replacement the right way.

Locate the shutoff valves beneath your sink one for hot water and one for cold. Turn both clockwise to stop the flow, then open your faucet to release any leftover pressure. This quick plumbing repair step helps prevent leaks and messy surprises later on.

If the valves are stuck or rusted, wrap them with a towel or use pliers for better grip, but be gentle — forcing them can cause damage.

How to Remove an Old Sink Faucet

Now comes the slightly tricky part: how to remove an old sink faucet and install a new one.

1. Place a bucket under the sink to catch any drips.
2. Disconnect the water supply lines using your wrench.
3. Unscrew the mounting nuts that hold the faucet in place (a basin wrench helps if space is tight).
4. Once loosened, lift the old faucet straight out.

Taking a minute to clean the sink surface old grime, rust, or sealant can prevent the new faucet from sitting evenly.

Prepare and Install the New Faucet

This is where your project starts to take shape. Insert your new faucet through the mounting holes in the sink. Use the included gasket or plumber’s putty to ensure a watertight seal.

Tighten the mounting nuts from below hand-tight first, then secure gently with your wrench. Avoid over-tightening (one of the common mistakes when changing a faucet) because it can crack the fixture or strip threads.

Connect your water supply lines make sure hot and cold lines are attached to the correct valves.

Test for Leaks and Adjust

Once everything is connected, slowly turn the water back on. Check under the sink for drips or leaks.

If you spot any, tighten connections slightly or reapply plumber’s tape. Turn on the faucet and let it run for a minute to flush out debris.

Congratulations, you’ve just learned how to change sink faucet successfully!
