I’m giving this a bump so hopefully @Joseph Corlett, LLC will read and weigh in.

A quick google search provides lots of 27” farmhouse sinks. You just need a woodworker to cut down the cabinet sides and build the support for the sink. Hopefully your doors won’t need to be altered or can be done easily. Photos?

The trick is getting a 27" SHORT APRON sink for retrofitting. Check the Kohler Whitehaven please.

Thanks for your reply. Most 27" farmhouse sinks that we've seen through google searches seem to require a larger base cabinet - cutting the cabinet, or even having one made specifically for this space might be the only way. If we want to keep the cabinet centered on the window, we really have no wiggle room to left or right. To the immediate right is the DW, then fridge, then door to outside. It is tight and I think our only remedy is to build a cabinet. Thanks for your feedback.

Yes the cabinet will need to be cut (easy) but you want to avoid getting new doors made. How tall is that fake drawer? 6”?
