What Is the Difference Between Installing an Undermount Sink and a Drop-In Sink?
Drop-in sinks are typically installed after the countertop is set up. Of course, the countertop should already have precise cutouts. After applying caulk, installers slide the new sink snugly into place.
Undermount sinks require installing specialized clips on the underside of the countertop first. These clips are responsible for bearing the entire weight of the sink. in addition to that undermount sink adhesives can be used.
Drop-In to Undermount Sink Conversions
Drop-in sink to undermount conversions are possible, but that is going to depend on your countertop. Your drop-in sink shape will have to be matched by the undermount shape, and in addition to that, you will have wear and tear from the lip of your drop-in that you can't hide. So, while there is a way that you can technically do it, the result you achieve will not be aesthetically appealing without further work to your countertop.

FAQs
What is an undermount sink?
An undermount sink is installed from under your counter, and so the sink has no extra lip area on your counter like a drop-in sink does. The undermount design creates a seamless movement from your counter to sink without any separation or divides between the counter and sink.
What's the difference between an undermount sink and other sink?
The difference between an undermount sink and another sink, which is typically a drop-in sink is that the undermount version is installed from the bottom up, so there is visible attachment between the counter and sink. A drop-in sink is installed from the top so your sink has a lip that goes over your counter and you can see the installation.
What does an undermount sink sit on?
Your undermount sink doesn't sit on anything. It is held up by heavy-duty clips and sealants. If you have a very heavy undermount sink, your installer may place supports underneath.
