Replacing a bathroom faucet is one of those home improvement projects that can make a surprisingly big difference. A new faucet can freshen up an outdated bathroom, fix a leaky fixture, or simply give your sink a cleaner, more modern look. The good news? For many homeowners, replacing a bathroom faucet is a manageable DIY project.
Before you grab your tools, though, it helps to know what you’re getting into. Here’s a simple guide to replacing a bathroom faucet and knowing when it may be time to call a professional.
What You’ll Need
Most faucet replacements require a few basic tools and supplies:
- Adjustable wrench
- Basin wrench
- Screwdriver
- Plumber’s tape
- Bucket or small container
- Towels or rags
- New bathroom faucet and any included hardware
It’s also a good idea to check your new faucet before removing the old one. Make sure it matches the number of holes in your sink or countertop and that the included supply lines will work with your existing plumbing.
Step 1: Turn Off the Water
Start by turning off the hot and cold water supply valves underneath the sink. Turn the faucet on for a few seconds to release any pressure remaining in the lines.
Place a bucket underneath the connections to catch any water left in the supply lines. Trust us – this small step can save you from a surprise puddle on the bathroom floor.
Step 2: Disconnect the Old Faucet
Using your adjustable wrench, disconnect the hot and cold water supply lines from the faucet. If they’re difficult to reach, a basin wrench can make the job much easier.
Next, loosen the nuts holding the faucet to the underside of the sink. Once the hardware is removed, lift the old faucet out from the top of the sink.
This is also a good time to clean away any old caulk, mineral buildup, or grime around the faucet openings.
Step 3: Install the New Faucet
Follow the manufacturer’s instructions for installing your new faucet. Typically, you’ll place the faucet through the sink openings, install the mounting hardware underneath, and tighten everything securely.
Be careful not to overtighten the mounting nuts. Snug is usually enough – too much force can damage the sink or faucet.
Connect the hot and cold supply lines, making sure each one goes to the correct side. If the connections call for plumber’s tape, use it according to the faucet manufacturer’s instructions.
Step 4: Turn the Water Back On
Slowly open the water supply valves underneath the sink. Check each connection carefully for leaks.
Turn the faucet on and let the water run for a minute or two. This helps flush out debris that may have entered the lines during installation.
If everything stays dry, congratulations! You’ve just replaced your bathroom faucet.
When Should You Call a Professional?
Not every faucet replacement goes according to plan. Corroded connections, damaged shutoff valves, leaking supply lines, or older plumbing can turn a quick project into a much bigger one.
If you’re dealing with plumbing problems you aren’t comfortable handling, it’s perfectly reasonable to call a professional. A qualified handyman or remodeling contractor can also help if your faucet replacement is part of a larger bathroom update.
