I would like to replace my undermounted kitchen sink but do not want to change the tile around it. Can I get a top mounted sink and insert it in the old sink?

Old sink must be removed.

You may be able to find a sink that will fit into the opening.

Before I would try to do that I would make sure you can get a sink to fit. Then, you would have to figure a way to attach it to the old counter and would have to pre install the basket, tail piece and faucet and hope all the holes line up. Undermount sinks are not that hard to remove. You have an undermount in a laminate top with a tile surround? Can't picture that.
