How to Replace Undermount Sink Without Removing Countertop in 5 Easy Steps

Step 1: Remove the Old Sink

Remove the Old Sink

The very first step is to remove the old sink. Disconnect the plumbing, unscrew any fasteners that are holding it in place, and then gently lift it out of the countertop. But you have to make sure to take extra precautions when doing this as most under-mount sinks are made of glass or other fragile materials.

Step 2: Prepare the New Sink

Once you have the old sink removed, you will need to prepare the new one. Start by getting all your supplies ready and make sure that everything is properly fitted before placing it into the countertop.

Step 3: Place the Sink in Position

When you are ready to place it on the countertop, you should use a putty knife or another thin tool to spread some caulking around the rim of the sink. This will help to make sure that it is sealed and secure when placed on the countertop.

Step 4: Secure the Sink

The next step is to secure the sink in place. Use a drill to attach some screws into the underside of the countertop, and make sure that they are tight and secure. You may also need to use some additional caulking around the edges of the sink where it meets the countertop.

Step 5: Clean and Test

Once you have secured the sink to the countertop, it is time to do a final check and make sure that everything is properly sealed. Use a damp cloth or sponge to clean up any excess caulking and then turn on the faucet to make sure that there are no leaks. If all looks good, you can now enjoy it!

Some Additional Tips to Replace Undermount Sink Without Removing Countertop

1. Do Not Remove the Old Sink

When replacing an undermount sink without removing the countertop, do not remove the old sink. This is because the old sink may be necessary to install a new one in its place. Ensure that all of the caulk and sealants are removed from around the edges of the old sink before beginning installation on a new one.

2. Remove the Drains and Faucets

Before beginning the installation of a new sink, remove the drains and faucets from the old one to make room for installing a new sink in its place without damaging existing fixtures or plumbing lines.

3. Cut Holes for New Sink

Using a jigsaw and a sharp blade, carefully cut the holes for installing the new sink. Ensure that each hole is only slightly larger than the outward edge of the new sink to ensure proper installation. Also, ensure that these cuts are properly sealed with caulk to prevent water from seeping into the joint.

4. Install the New Sink

Caulk Around the Edges

Use a putty knife to spread a thin layer of caulk around the edges of the new sink before sliding it into position. Make sure that all areas are securely caulked and left undisturbed for a few hours to allow the caulk to set. Once this is done, attach the drain and faucet components with washers and screws as needed.

5. Test the Installation

Finally, test the installation of your new under-mount sink by running water through it and making sure that everything is working properly and there are no leaks.

Make sure to also check the caulk around the edges and recaulk any areas that may be loose. With these steps, you should be able to replace an undermount sink without removing the countertop.

With these tips and a bit of patience, you can replace your undermount sink without having to remove the countertop. Good luck!
