Cut the cabinet sides to accommodate the new sink.

Thanks Treb - That seems like an obvious solution but I forgot to add that one side is the dishwasher.

If your cabinets have a face frame, you will have, at least a 3/4" space in the DW alcove.

That plus the 5/8 cab. would allow you more that two inches of adjustment.

Thanks for the advice. I crawled under the sink with a measuring tape and showed DH the extra space beyond the current cut out.

He was skeptical but agreed to try to expand the current cut out to get a sink to fit. He had no trouble trimming our current counter and is now installing my new sink. Thank you! You have no idea how much I hated our old, stained, beige speckled composite sink.

He is now puzzling over the garbage disposal so I will save my "told you so" for later.
