You don't have to have a prep sink at all unless you want one. Sailorman suggested moving the cleanup sink to the island because its closer to the ref. Range to sink and Ref to sink are critical to how a kitchen functions because they are frequently walked. People are concerned because the ref is around the corner and far from a sink (think its at least 16 feet one way). So everybody is suggesting to do something about the sink position or add a sink. Guessing from the cabinet measurements, I think your island could up up to two feet longer. This would allow you to have a nice eight foot long island with the sink and dw and trash in it and maybe an 15" drawer or door unit. You would have 8 feet of the one foot deep cabinets or a single seater stool. This would change the outside wall configuration - like have a 30" drawer base with micro, range, 15" pullout or drawers, 36" super susan, and up to 3 36" drawer units and a 30" drawer unit on the back wall. (There rather disguised hints in there that the pullout and super susan would be perhaps difficult to access and that the micro might be better off in a place where it didn't face another major appliance and was closer to the range and ref). From a kitchen users perspective it's really a case of figuring out where you want to chop and how far you want to walk! There isn't much difference between prepping between the sink and the range on the outside and the sink and the range on the extended island except for steps to the ref.

THE ONES WE USED ARE BY SAFTEY FIRST OR THE FIRST YEARS I CAN'T REMENBER WHICH AND DID GET SCREWED IN BUT TO THE BACKSIDE OF THE CABNIT AND THEY WERE MAGNETIC.THERE WAS NO EVIDENCE OF LOCKS WHEN YOU LOOKED AT THE CABNITS! THESE WOULD ONLY BE GOOD IF YOU HAD THE CHILDREN ALOT BECAUSE YOU USE A MAGNET TO OPEN THEM (NOT VERY CONVENIENT). WE KEPT THE MAGNET ON THE SIDE OF FRIDGE AND A SPOT ON THE WINDOWSILL THAT HAD METAL. WE LIKE THEM BECAUSE THEY DID NOT OPEN AT ALL SO NO FINGER PINCHING. THE STRAP KIND LET THE DOOR OPEN SLIGHTLY AND THEIR FINGERS CAN GET IN THERE.

Look into Coretec, Adura Max, Karndean, and Flooret for good quality click lock vinyl flooring. Unless you plan to self-install, I strongly recommend finding a local flooring company known for excellent quality and good installation. Take home samples and look at them in morning, afternoon, and evening light. Flooret does not sell to resellers, but they can probably recommend local installers. Weshipfloors.com has good prices on vinyl flooring, but I cannot recommend or not recommend as I have never purchased from them. They have a line of vinyl plank flooring called "Kryptonite," and it's pricing is very good. Here's a light colour somewhat similar to what you posted that is very pretty: http://www.weshipfloors.com/flooring/silver-tail-luxury-vinyl-plank-flooring-3mm-x-63-x-48-cork Flooret has beautiful colours: http://www.flooret.com/modin-vinyl-plank-flooring/ Adura Max by Mannington: https://www.mannington.com/Residential/AduraMax/Search I'm having 2700 sq. Ft. of Adura Max Dockside Sand installed in a few weeks. Will post photos if you haven't made a decision by then. Coretec Dakota Walnut was my second favourite colour. The sample I brought home was lighter than the website photo: http://www.usfloorsllc.com/flooring-products/dakota-walnut/ I'm running out of time so cannot post Karndean link. Hope this helps!

I am looking for someone who can build two small (24-28 inch wide) bathroom vanities. Thank you!
