I have a coriane kitchen counter top, with a double sink. The larger section of the sink is cracked all the way through to the bottom, and is leaking. I know that the counter top itself
can be sanded when there are small scratches, but is there anyway to repair or replace this cracked sink? If so, can it be done in the house, without removing the counter top from the cabinets, as it is a large l-shaped counter, measuring approximately 8'x12' in length.
Any advice you have would be greatly appretiated.
Sincerely,
Tammy Herbers

A regular installer may not be able to do in place, There are people very crafty and can probably do in place, If they can't do in place, keep looking.
