We have a tiny kitchen that currently has a 21 inch (overmount) sink. We'd like to switch to undermount and can't go any bigger in size. However, every sink I see online that is about that size (there aren't many) needs a 27 inch base cabinet which won't work with our ideal layout. The sink needs to go side by side with a fridge and a dishwasher in a row. Is there any small sink out there that can be mounted into a 24 inch (or smaller) base cabinet or is that just structurally impossible? If you can point me to any resources, I would appreciate it.
