Is this a layout you already vetted here? You have the space to have a really great kitchen with a big sink and lots of counter if you ran more counters under the window on the right and put the sink there.

Generally, when an island gets to be that small, it means you simply don't have space for one with the layout you have and should just nix the island altogether.

Could the table be moved out of the kitchen proper? Maybe to where a person would stand to view the kitchen from this angle?

Can the short window be made the same height as the other windows?

My kitchen is similar in size to yours, and I got a 30" sink with a 27.5" wide basin. But I bake a lot, and I can't stand washing cookie sheets and pans in sinks that can't fit them easily. Water gets everywhere and the faucet gets whacked and life is just bad.
