But here’s the truth: learning how to change a kitchen faucet is one of the most satisfying and surprisingly simple DIY jobs you can tackle in your home.

So grab a cup of coffee, clear your schedule for an hour or two, and let’s dive into this step-by-step guide that’ll turn you into a faucet-changing pro in no time.
Why You Should Know How to Change a Kitchen Faucet
Save Money on Plumbing
Let’s get real for a second — calling a plumber for even the simplest job can cost you more than you’d like to spend. They usually charge by the hour, and those hours add up fast. Why pay someone else for something you can easily do yourself with just a few basic tools and a bit of time? Changing your kitchen faucet might seem intimidating at first, but once you do it, you’ll realize how straightforward it really is. Plus, the money you save can go towards something you actually enjoy — like a fancy dinner out, a new kitchen gadget, or maybe that subscription box you’ve been eyeing for months.
Customize Your Kitchen
Replacing your faucet isn’t just about stopping leaks — it’s also a fantastic chance to give your kitchen a mini makeover. Think about it: the faucet is one of the most used fixtures in your kitchen. So why settle for something dull and outdated when you can pick one that matches your style perfectly? Whether you want a sleek modern faucet with a pull-down sprayer or a rustic farmhouse vibe with an antique brass finish, installing a new faucet can instantly freshen up the entire look of your kitchen without the need for a full remodel.
It’s Easier Than You Think
Here’s the best part — changing your kitchen faucet is way less complicated than you might imagine. Sure, you might get a bit wet and have to squeeze into that awkward space under your sink, but with the right tools and a clear plan, the whole job can be done in an afternoon. No special training, fancy equipment, or prior plumbing experience required — just a bit of patience and a willingness to give it a go. Once you’ve done it once, you’ll feel so much more confident tackling other little plumbing fixes around your home.
Tools and Materials You’ll Need
Essential Tools
Before you roll up your sleeves, let’s talk tools. You don’t need a whole toolbox full of fancy gadgets — just a few basics that you probably already have lying around your garage or utility drawer.
Wrench
A sturdy adjustable wrench is a must-have. It’s perfect for loosening those stubborn nuts under the sink and making sure your connections are tight enough to prevent leaks. If you don’t have one yet, it’s a solid investment for any homeowner.
Plumber’s Tape
Also known as Teflon tape, plumber’s tape is like magic when it comes to creating leak-proof seals on threaded connections. A few wraps around the threads will help keep water where it’s supposed to be — inside your pipes.
Bucket
Things can get drippy when you’re disconnecting supply lines, so have a bucket ready to catch any leftover water. It’ll save you from dealing with a soggy mess and prevent water damage to your cabinet.
Towels
Old towels are your best friends for any plumbing job. Lay them down under the sink to protect the cabinet and soak up any unexpected drips or spills. Trust me, you’ll thank yourself later.
Choosing the Right Faucet
Not all faucets are created equal, and choosing the right one is half the fun. Before you shop, check your sink to see if it has a single hole or multiple holes — and measure the distance between them if there’s more than one. This will determine what type of faucet will fit. Think about the features you want, too. Do you want a pull-down sprayer to make rinsing dishes easier? A touchless faucet for added convenience and a bit of tech flair? Take your time browsing options, read reviews, and pick a faucet that fits both your sink and your style.
Preparing for the Job
Shut Off the Water Supply
First things first — you absolutely need to shut off the water supply before doing anything else. Under your sink, you should see two valves: one for hot water and one for cold. Turn each valve clockwise until it stops to shut off the flow of water. Give the faucet a quick turn to make sure the water’s really off — nothing worse than an unexpected shower when you’re under the sink. If your sink doesn’t have shut-off valves (some older homes don’t), you’ll need to shut off the main water supply to your entire house. It’s worth taking a moment to figure this out before you start — you’ll save yourself a huge headache later.
Clear Out the Under-Sink Area
Next, take everything out from under the sink. Cleaning supplies, bags, recycling bins — whatever’s down there needs to go. You need plenty of room to move around, see what you’re doing, and have your tools handy. Plus, it’ll keep all your stuff clean and dry while you work.
Gather Your Tools
Before you crawl under the sink, make sure you’ve got all your tools within reach: your wrench, plumber’s tape, bucket, towels, and of course, your shiny new faucet. Having everything ready to go means you won’t have to crawl out and back under a dozen times to grab things — which, trust me, gets old fast.
How to Remove the Old Kitchen Faucet
Disconnect Water Supply Lines
Position your bucket under the sink, right beneath the water supply lines. Using your wrench, carefully loosen the nuts that connect the supply lines to the faucet. Have a towel handy because there might be a bit of water left in the lines — that’s totally normal. Let any leftover water drain into the bucket. This part is easy, but take your time and make sure you don’t damage the supply lines if you plan to reuse them.
Loosen the Mounting Nuts
Now it’s time to get rid of the old faucet. Look up under the sink — you’ll see big mounting nuts that hold the faucet in place. Depending on your sink and faucet model, you might have one or two mounting nuts to loosen. Using your wrench, gently loosen and remove these nuts. This can be the trickiest part if they’re corroded or stuck, so don’t get frustrated. A little penetrating oil can work wonders if the nuts won’t budge.
Remove the Old Faucet
Once the nuts are off, head back up top. Gently wiggle the faucet back and forth to break any old sealant or plumber’s putty that might be holding it in place. Lift it straight up and out of the sink. Congratulations! You’re halfway there.
Cleaning Up Before Installation
Clean the Sink Area
Take a few extra minutes to clean the area where the old faucet sat. Scrape away any old caulk, putty, or gunk with a plastic scraper or an old credit card. Wipe everything down with a damp cloth to make sure the surface is clean and smooth. A clean base means your new faucet will seal properly, which is key to preventing leaks.
Check for Rust or Damage
While you’re at it, check the sink and pipes for any signs of rust, corrosion, or damage. If you see anything concerning, now’s the time to deal with it. Fixing small problems now can save you a big headache later. If everything looks good, you’re ready for the fun part — installing your new faucet!
Installing the New Faucet
Insert the Faucet Into the Sink Holes
Grab your new faucet and carefully feed its supply lines through the sink holes. Make sure it’s facing the right direction — you don’t want the handle pointing backward or the spout aimed at the backsplash. Double-check the alignment before you move on.
Secure the Faucet with Mounting Nuts
Under the sink, find the new mounting nuts that came with your faucet. Thread them onto the faucet shank by hand first, then tighten them securely with your wrench. Be careful not to overtighten — you want them snug enough to hold the faucet steady, but cranking too hard could crack the sink or damage the faucet’s threads.
Attach the Water Supply Lines
Next, connect the water supply lines to the faucet’s shanks and the shut-off valves. Wrap plumber’s tape around the threads to help create a watertight seal. Tighten the connections with your wrench, but again, don’t overtighten — a good firm connection is all you need.
How to Check for Leaks
Turn On the Water Supply
Alright, here’s the moment you’ve been waiting for! Slowly turn the shut-off valves back on, one at a time. Head up top and turn on the faucet to get the water flowing.
Inspect Connections
While the water’s running, crawl back under the sink and take a good look at all your connections. Feel around the supply line nuts and faucet base with your fingers — if they’re dry, you’re good to go.
Tighten if Necessary
If you notice a drip, don’t panic. Turn off the water, tighten the connection slightly, and try again. A little more plumber’s tape might help if you’re still seeing leaks.
Tips for a Smooth Installation
Use Plumber’s Tape
Don’t skip the plumber’s tape — it really does make a difference. A few wraps around threaded connections can mean the difference between a tight seal and an annoying slow leak that shows up days later.
Get Help if Needed
Some faucets can be heavy or awkward to hold in place while you’re securing the nuts underneath. If you have an extra set of hands around, ask for help. Having someone hold the faucet steady while you tighten things up can make the whole job smoother and faster.
Common Mistakes to Avoid
Forgetting to Shut Off Water
It’s worth repeating — don’t forget to shut off the water! If you skip this step, you’re basically inviting chaos into your kitchen. Water everywhere, ruined cabinets, a very unhappy you — just don’t do it.
Over-Tightening Connections
When it comes to plumbing, tighter isn’t always better. Over-tightening can damage threads, crack fittings, and actually cause leaks instead of preventing them. Tighten firmly but stop before you feel like you’re wrestling with the pipe.
When to Call a Professional
If Pipes Are Damaged
If you discover cracked pipes, corroded connections, or anything that looks beyond a simple fix, don’t be afraid to wave the white flag and call in a pro. Better to spend a bit now than deal with a burst pipe later.
If You Encounter Mold or Rust
Mold or extensive rust is a red flag that there might be bigger issues behind your sink or walls. A licensed plumber can help you deal with any hidden problems safely and thoroughly.
Maintaining Your New Kitchen Faucet
Regular Cleaning
Keep your new faucet looking shiny and new with regular cleaning. Wipe it down after each use to prevent water spots and mineral buildup. For stubborn spots, a bit of white vinegar on a cloth can work wonders.
Check for Drips
Make it a habit to check under the sink every few months for signs of leaks or drips. Catching a tiny drip early can save you from costly water damage down the road. It’s an easy habit that pays off big time.
Final Thoughts
Learning how to change a kitchen faucet is one of those handy life skills that pays for itself over and over again. You save money, give your kitchen a fresh look, and feel like a total DIY rockstar every time you turn on the tap. Sure, it might take a bit of elbow grease and patience, but once you’ve done it, you’ll wonder why you didn’t try it sooner. So next time you hear that annoying drip or get tired of looking at that dated faucet, you’ll know exactly what to do. Happy fixing!
