Please Help Me With Vanity and Sink!!

Submitted to Community Chat

I bought this home a little over a year ago. Then I was I am in remission and am ready for updates. I was told by a handyman friend that if I try to take off the counter and sink, it will ruin the cabinets beneath. They are probably glued down...he said. The cabinets are in great shape, and would be very costly to replace....

I would appreciate any advise on how to approach this project....thankyou so much, in advance, for your help.

If any of you have tried any ways of soing this please let me know how it has held up. I was even thinking of doing concrete.
