Want to know how to change a kitchen sink? Tired of constantly repairing your old kitchen sink? Or perhaps you want to replace your worn-down sink with a chic new one? Carry on reading to find out an in-depth easy to understand guide on how to replace your kitchen sink.
Disconnecting Water Lines
In order to replace your kitchen sink, you will firstly need to disconnect the supply and drain lines. You need to do this extremely carefully so as to not damage them and loose water supply in your kitchen.
Here’s how to easily do this:
- The water supply valves must be turned off. You can find these under the sink. Simply turn them in the counterclockwise direction to disable them.
- Get rid of water stored in the faucet by turning it on. This will barely take a few seconds.
- Use an adjustable wrench to disable the water supply lines by spinning the connector holding them together counterclockwise. We recommend labeling all parts so it’s easy to reconnect them once you’ve installed the new sink.
- Unplug and remove the garbage disposal and dishwasher pipe.
- Use pliers to loosen the pipes making the p trap and take them apart.

How to change a Kitchen Sink?
Remove your old sink
There are two types of sinks; a Top Mounted Sink and an Undermount Sink. The former is more common. It rests on the upper part of the countertop and uses metal clips and caulk to attach to the perimeter of the sink. The latter is less common. Like its name suggests, it rests on the bottom of the counter top.
Each type of sink is removed and installed differently. We will cover each one in detail.
Top Mounted Sink
Firstly, ensure that your sink is the right size by putting it in the countertop hole. If it fits, you are good to go. Otherwise, you’ll need to use a tile cutter to modify the countertop according to the sink’s size. It does help to measure your old sink to get the correct dimensions for the new sink and avoid any inconvenience caused by a wrong sized sink.
Follow the steps given below to remove a top mounted sink:
- Remove the metal clips present on the underside of the counter along the perimeter of the sink using a screwdriver.
- Cut the caulk (sealing material) using a utility knife.
- With the nuts and caulk out of the way, you will now simply push the sink unit from below to remove it. Once the unit is out, set it aside.
- Be sure to clean all the mess ( grime, caulk, and putty) before you install the new sink.
- This completes the process of removing the old sink and making way for a new one.
- Now, secure your new sink to the countertop in the following way:
- Cover the underside of the new sink’s perimeter with silicone caulk and carefully put it in the countertop hole. Remember to wipe off excess caulk using a rag.
- To hold the sink in place, use metal clips. Fasten them around the perimeter of the underside of the sink. The open mouths of the clips should be facing towards the counter. Just use your old clips if they are not rusty and are in good condition.
For replacing an Under mount Sink, you’ll need to follow the steps given below:
- Firstly, you need to remove the sink. For this, you will need a piece of wood. This will act as a support and will prevent your sink from falling down once you loosen it. The wood needs to be longer than the sink’s width and must be placed diagonally over it.
- Next, use a bar clamp to secure the piece of wood to the sink. Attach one end to the wood and drop the other end into the drain and tighten it. Use two bar clamps if you have two drains to make sure that the sink has sufficient support.
- Use a caulk remover to remove caulk from the sink’s rim(present on the underside). Be sure to use protective eyewear to prevent the remover from getting in your eyes. Also, let the remover soak into the caulk based on the time recommendation present on the packaging.
- There are additional clips holding the sink into place. You will need to crawl underneath the sink to loosen them. Use a wrench or screwdriver for assistance. We also recommend storing the clips for your new sink if they are in good condition.
This will detach your sink from the countertop. Now, carefully and safely remove the bar clamps and wood and lower the sink to take it out of the cabinet.
All you need to do now is install the new Undermount Sink. The process is quite easy and simple but you will need a friend to help you out.
Here is how to install your new sink:
- Spread caulk along the top part of the perimeter of the sink. Then, bring it up through the cabinet and adjust it in the countertop hole.
- Your friend will need to hold the sink in place while you fasten the clips on the underside of the sink. Place the clips in the pilot holes of the countertop. Once you’ve done this, your sink will be securely held in place.
Reconnecting Water Lines
Once you are done with replacing your kitchen sink, you will need to reconnect the supply and drain lines.
Mentioned below are all the steps you need to follow to have a fully functioning kitchen sink:
- Attach the faucet to the sink by setting it in the hole present on the sink’s top part. Next, put the faucet lines through the sink’s bottom into the faucet. Hold them in place using washers and nuts.
- Place the drain strainer in the sink drain using putty.
- Next, attach the faucet lines to the water supply lines(you can find them coming out of the wall).
- Make sure to reinstall your garbage disposal unit and dishwasher pipe.
- Assemble and connect all the labeled pipes that disconnected before sinking removal.
- Turn on the water supply and check for leaks.
If there are no leaks, you have successfully replaced your kitchen sink. Now enjoy washing your dishes in a stunning brand new sink!
