My backsplash is also granite and behind the stovetop. If the sink cannot be replaced, I will have to replace about 30 linear feet of granite plus about 18 feet of backsplash that ranges from 15 inches to 24 inches high. There is now a way I could match the granite I have to just replace where the sink is. Thanks for any information.

Answered by Todd's Home Services: The short answer is yes it can be replaced. However, I do recommend having a granite contractor do the replacement. The adhesive used to hold the sinks under the top is very strong once adhered. It will likely have to be cut and ground out from the underside. A regular grinder isn't the thing to use for this as the rpm's have to be just right so the vibrations don't damage the granite. Some commercial adhesive removers may eat the glue and get the sink loose but make sure it doesn't come in contact with any visible surfaces on the granite. Also, the granite may have to be cut and polished to line up with the new sink properly.

Check out granite contractors in your area on Angi and check their records for complaints with the BBB. That's your safest option.

Answered by bobthebuilder53: I would start by locating a new sink that matches the cut-out you have, and then hire a granite fabricator to cut out the old sink (not a simple procedure), and attach the new sink. Having the granite cut and polished on site for a radically different shape would be quite expensive unless you want for a drop-in sink, which requires only a rough cut-out.
