question - is the path from the door in the back past the fridge and island a main thoroughfare in your home? If it is, you might need more clearance between the fridge & island. What is the distance between the corner of the counter at the top and the fridge?

I have the same concern as mebry. That upper right corner in the floorplan looks much too tight. No one will be able to walk into the kitchen if someone else has the fridge door open. I speak from firsthand experience here -- our kitchen before the remodel had a peninsula run and a fridge just across from it, and it made for a big traffic jam.

I would make the peninsula run along the top wall of the floorplan at least 18 inches shorter.

With your island width -- I don't think you will have room to pull the fridge out for repairs if you do anything larger than 27 inches wide on the island. (The typical overhang for the countertop over the edge of the cabinetry is 1.5 inches, so if you allow for that on either side, your island top will be 27 inches wide.)

Are you committed to having an island? Would you consider a work table? Our kitchen is similar in size and layout. We found that in order to get the clearances we needed an island would have looked too dinky in size. But we also felt a worktable looked more appropriate in our 1920's house and vintage looking kitchen. If you really want to have electric or gas I have seen islands where the power is run through the legs. Of course, then they are locked in place, but you get the lighter look of a table.

On the plan the distance from the corner of the fridge to the closest corner on the penisula is just over 3', probably about 38". Even if I shortened the penisula by only 6" (to be the same distance as the run on along the bottom) that should give us about 44" which would be more than enough room at that corner I would think.

Regarding the throughfares, the opening on the bottom leads to the mudroom, laundry and garage. The one on top leads to the breakfast room and the one on the right leads to the living room.

Actually, now that I look at it, the plan appears to show a counter depth fridge (30"). The fridge we've selected is 35" deep (plus about 2" in rear for water and power connections). This would mean that the distance to the corner of the peninsula would be closer to 30" before shortening the peninsula! With shortening the peninsula just 6", would the 36" be enough room considering that the fridge is not directly across from the peninsula but rather at an angle?
eastbaymom - good point about being able to pull the fridge out. I believe we're just doing the standard 1.5" overhang so should still have about 38" between edge of island and fridge, with room to pull out a 35" fridge.

Thanks everyone for the advice so far!

Make sure that 35 inches includes the front handle on the fridge -- they had to take the handle off of ours to move it into the kitchen.

It is sometimes possible to recess the water and power connections between two studs behind the fridge. I would definitely look into it in your kitchen.

Are you getting a single door fridge or French door? If you actually draw out the swing of the door on your graph paper, you'll get a better idea of whether the 36 inches is enough clearance for you.

I just checked the Whirlpool website and the 35" does include the handle. I know that the water valve is recessed and the electrical shouldn't take up too much room. Whirlpool recommends .5" at the rear for circulation so my 2" for installation may have been a little conservative and I should be able to push it back and only lose 1".
Its a French door, the total depth is 48" with the door open at 90 degrees. I'm going to call the cabinet man in the morning to discuss shortening the peninsula some. I'm glad ya'll caught that!
