Sink is in the corner and is really the only place for it. I was thinking of having a custom stainless sink made. Saw this and thought it was a great idea. https://www.pinterest.com/pin/434175220308479038/

I also will have a 16 inch Dishwasher. I think it will be plenty of space for the two of us as the kids leave and I am not a big fan of the DW.

So many questions... Hard to give advice without photos of the current space. Many of the items aren't clearly labeled, maybe print your picture and label the main things- range, sink, etc.

First impression is to turn the island 90 degrees, correct the clearances, get rid of the angled cabinet (range?) and somehow tie the pantries into the rest of the kitchen.

angle is the sink-- can't get rid of it.

Ok will try again--

There should be a minimum of 3 feet of space between the island and cabinets.
