Intalling larger undermount sink in existing quartz counter?

Posted by olivesmom (My Page) on

How difficult would it be to change out the sink in an existing quartz countertop? The current sink is an undermount double bowl and I am considering a much large under mounted Kohker stages. Can the current counter be cut on site? Or will a new a new slab be required? And if a new slab is required, how likely is it to get a match for white quartz? Is there much variation between quartz slabs, or are they pretty consistent?

You should have no problem getting a fabricator to remove that top, sink and all, re-fabricate the cut-out, and reinstall the top with the new sink in it. I'd do it in the front yard, but some guys will want to take it back to the shop.

Expect to be charged under a thousand dollars with plumbing included. No guarantee on damaging the splash though, although that's unlikely.

Stages requires you to not have a top drawer in the cabinet under the drainboard side and can't be installed on top of a DW. It also requires that you cut into the cabinet sides for that drainboard, meaning you need to add in additional support for the counter at that point. You could do a large single sink replacement just fine without all of that though.
