A new kitchen sink can give your kitchen an entirely new feel, but installation can be costly. Learning how to install a kitchen sink yourself may save you money, but it can be complicated if you aren’t comfortable working with water lines or, worse yet, creating a larger hole than the existing sink. If you have experience working with home plumbing, follow this guide to install a kitchen sink and save on labor costs.
How to Prep for Kitchen Sink Installation
Before installing a new kitchen sink, take the time to prepare. These prep steps can save you from making expensive and detrimental mistakes. Start by determining the right kitchen sink size. Sticking to a sink that fits the current opening size is best as it eliminates the need to enlarge the opening.

How to Remove Your Old Kitchen Sink
If you’re not installing a kitchen sink for the first time and need to remove your old sink, you’ll need to remove your old kitchen sink before you can put in the new one. Follow these steps to prepare your kitchen for a new kitchen sink.
1. Shut Off the Water Supply
Turn off the supply lines for your hot water and cold water by turning the shut-off valves until water doesn’t come out of the faucet when you turn on the sink.
2. Take the Pressure Off
To remove pressure in the water lines of your sink, turn the faucet or faucets on.
3. Disconnect the Water Supply Lines
Disconnect the water supply lines to your faucets using an adjustable wrench. Keep a bucket on standby for water exiting the supply lines after you’ve removed them.
4. Disconnect the Dishwasher Drain Line
Loosen the dishwasher drain line until it disconnects.
5. Disconnect the Disposal
Turn off the circuit breaker to your garbage disposal and unplug it before disconnecting the hardware from the sink. Use a bucket to catch water that drains or drips from the drainpipe.
6. Remove the Disposal
After disconnecting the disposal, keep the bucket nearby and then remove the disposal. Every disposal is different, so follow the manufacturer’s instructions to remove your garbage disposal.
7. Loosen the Sink Clips (Optional)
Not all sinks use clips to stay secured to the counter, but if you have an undermount sink, then you’ll need to do this step. With a screwdriver or wrench, loosen the clips securing your sink to the counter.
8. Cut through Old Caulk
Use a utility knife to cut the caulk securing the sink to the countertop. Work your way around the perimeters until you’ve gone all the way around the sink.
9. Remove the Sink
While you can do this step solo, it’s helpful to have a friend or family member push the bottom of the sink while you lift the top of the sink until it comes out of the countertop.
10. Clean the Area
With a putty knife, gently remove old mineral deposits, caulk, and plumber’s putty. Then, wipe away the debris until clean.

To install a kitchen sink, you must determine if you have an under-mount or drop-in sink and determine whether the hole already exists in the countertop or if you must make the hole. Be sure you have all the necessary tools before starting, and if you need extra muscle, have another person there to help.
1. Get Your Measurements
Before you can choose a new sink, you’ll need to measure the width, depth, and length of the old sink or the space where you’ll be installing a new sink for the first time. Use a measuring tape to measure each dimension, and write down the numbers so that you don’t forget when you go shopping.
2. Check the Opening
Even after you’ve meticulously measured your current sink’s dimensions, there’s still a chance that the new sink doesn’t fit as planned. Place the new kitchen sink into the existing opening to ensure your new kitchen sink fits before getting started to save you the trouble of having to go to the store when you’re ready to install it.
3. Adjust the Opening
If the sink doesn’t quite fit, then it’s time to bring out a jigsaw to cut the new hole. But before you get started, use a measuring tape to measure the exact opening, or trace the new sink’s outline and place it on the existing opening to see how much you must enlarge it.
4. Install the Faucet
Place the sink upside down on your countertop to install the faucet. Thread the faucet through the gasket sealing the faucet and sink, and then through the sink holes. Secure the faucet to the sink using the provided nuts and bolts.
5. Install the Disposal Mounting Bracket (Optional)
If you’re going to install a garbage disposal, then attach the disposal mounting brack before you install the sink, following the manufacturer’s instructions.
6. Install the Strainer
Next, place plumber’s putty around the strainer and push it up through the drainage hole. Don’t forget to secure the locknut on the strainer with pliers to ensure it’s properly installed.
7. Wipe Away the Putty
Use a dry rag or towel to gently wipe away extra putty around the outside of where the gasket meets the sink.
8. Apply Silicone Caulk
Before installing the sink, place a small, steady layer of silicone caulk around the perimeters of the sink’s lip.
9. Place the Sink
Now, turn the sink right side up, paying close attention to the front of the sink so that it aligns with the countertop’s edge. Make sure the sink is completely lined up before the caulk dries or you’ll have to remove the caulk and repeat this step for a flush installation.
10. Secure the Sink with Clips (Optional)
This is where a friend can come in handy. If you’re installing an undermount sink, then you’ll need to secure the sink to the countertop using clips. Work your way around the edges of the sink to secure the clips using the old sink’s pilot holes as a guide while your friend supports the bottom of the sink.
11. Connect the Water Supply Lines
Connect the shut-off valves to the water supply and install both hot and cold water lines. Connect the spray hose if your sink has one. Do not turn on the water yet.
12. Add the Drainpipes
Check the drain pipes to ensure the existing pipes fit the new sink. If not, make adjustments, such as cutting a pipe that’s too long or purchasing a new pipe if the existing pipe is too short.
Use your hand to tighten the plastic fittings and reconnect drain pipes for garbage disposals or dishwashers.
13. Seal the Sink
To keep water from slipping between the cracks of the sink and the countertop, squeeze a small, steady bead of the sealant around the sink’s perimeters.
14. Test for Leaks

Next, turn the water on and test for leaks. Keep your buckets under the pipes until you’re sure the sink is secure, and there aren’t any drips.
When you first turn the faucet on, it will likely sputter due to trapped air; let it run its course. Keep the water running and check all connections and drain pipes for leaks. If you notice leaks, try tightening the fittings, but be careful not to go too tight. If the leaks continue, consider replacing the hardware.
15. Turn on the Power to the Garbage Disposal and Dishwasher
Once you’re sure there are no leaks and the water runs well, turn on the power of the garbage disposal and dishwasher for full use of your new sink!
