I posted a topic yesterday about a vanity top for an undermount sink that i purchased. I got some really good replies and I am so glad I joined this chatroom. As I said before the cutout for the sink is 15" X 11". I found an undermount sink out of California that measures 15 3/4" X 11 5/8". I talked to the salesman and he told me that you want the undermount sink to be just a little bit bigger than the cutout. I dont know if he just wants to sell me the product to make a little money (ha ha). Do you think this will work for me?
