Your island will have the bare minimum prep space to the side of the sink, but the layout of the kitchen is way better with that option. I do not like the layout with the range next to the fridge. Note that you don't want anyone walking past your range to get to your fridge if you can help it, even if you are in an empty nest.

I'm have a food prep sink in my island and it has been a god send in doing advanced prep when cooking for a crowd. Although this is your only sink, you'll get the same benefit.

sink in island but I'd reduce the depth of island ...it's 54 in deep... thats too much .....push the oven stack away from fridge . You want counter beside fridge. If you push the entire island one foot closer to fridge wall youd have space on tv wall to place the equivalent of 12 in deep storage cabinets that you presently are hiding under island overhang. They will actually be easier to use for real storage and then the island can go back to a reasonable depth.

Which way is the dining room and which way is the living room?

The layout of my remodel-in-progress kitchen is very similar to your option with your island in the sink, even down to the opening into the laundry/mudroom. I'm very happy with both the aesthetics and function of the layout.

emilyam819, standing at the sink in the island you would be looking into the living room to the left of the sliding glass doors.

Decided on a sink yet?
