bumping up

I shall assume the counter top is in place and you want to cut the "already present" top to conform to the farm sink you wish to put in place of what is already there? In theory all stone can be cut on site...but it gets tricky and problems are par for the course. It might be worth the extra to have a counter top company remove the stone and cut it in the shop the the proper specifications. The best thing to do is to take some pics of what you have and then shop them around to your local kitchen/bath fitters to see what they say.

Perhaps this bit of clarity will help you get some answers.

Thank you!!
