With all due respect to LL, I disagree that just because an island is movable, you don't need to worry about its dimensions. If it's over-sized for the space - in other words, doesn't allow comfortable aisles - you'll need to move it so often that it will be a PITA. It's not going to be a light little thing that is easy to shift, it's going to have some weight to it, especially if it has a stone top and has additional weight from the items you store on it. I would find an island that fits the size so that you only need to move it on rare occasions, not on a frequent basis. I drew up 2 variations of the U lay-out with an island and banquette seating. This allows you a 27" x 44" island, which I think is large enough to be useful. The aisle measurements are fridge (handles included, est 35" deep) to island counter, island counter to sink run counter, range run counter to island counter, peninsula counter to exterior wall, peninsula counter to table and table to wall. Oops, I forgot to adjust the above plan to show two 24" cabs to the left of the range. I do show that on Plan A-2. The plus with the banquette in this plan is that those seated on the bench can slide in and out without asking someone to slide out first. The downside is that clearances between the table and top and bottom walls is a bit tighter than recommended (44" for walk-behind aisles). You could center the banquette and have nearly 39" at each end instead of slightly off-center as I drew it. Here's a variation of the above. This plan creates an L banquette, which allows room for wider aisles at the top and room for a 30" cabinet next to the table. You can use this as your Command Central. The downside is that the person seated in the lower right corner will need to ask someone to move in order to get in and out. Some people are okay with that, others hate it. Here's an issue with both plans. It's a heck of a long hike - more than 11' - from fridge to sink in this plan. That definitely more than is recommended by the NKBA and for good reason. I'd like to see a water source between fridge and sink. However, the island just isn't long enough for a prep sink, IMO (I agree with a wise CMKBD, whose name escapes me at present, who advises against a prep sink in an island less than 60"). One option is to switch out the 36" corner Susan and make it a 36" corner sink cab for a prep sink. But ... then what purpose will the island serve? I agree that it would be nice to have a little more counter to the right of the sink, say by making that corner a 36" Susan cab, but that reduces the aisle between peninsula and exterior wall to 39". If there wasn't an in-swing door right there, that could be doable but since there is, I think a wider aisle here would be better. Which is higher on your wish list: an island or counter seating? If the former, I think Plan C is the better option for you. It has a good flow plus it leaves sufficient room for a kitchen table; no need to resort to a banquette.

Here's the link (did a google search for "60/40 sink gardenweb"). I agree with the others...put it near the divider :-) Here is a link that might be useful: 60/40 Sink Question

A few good ideas, and my little wicker basket was great. I'm in a bi-level, no doors to anything hidden, just the DR, LR and stairs down to entry door, or hallway to bedrooms. It's all open, no doorknobs even! No pantry either. We USED to drop them down over the stair rail where they landed on the 1st floor in front of the entry door from the garage! Not cool. Right now I have the basket in the DR, but don't want that to be my permanent solution. . . Under sink is low because of farm sink, but it's full! Recycling bin, DW soap, other clean up stuff. Maybe if I can find a cute basket with a lid that's small enough, I can keep it in the dining room. We used to have an old family wooden picnic basket, but I think after 60+ years it finally just fell apart.

The faucet and dispenser holes are filled with scraps from the cut-out. This is a job I did last week; removing a failed polyester bowl from a polyester solid surface top and replacing it with a stainless steel sink. No countertops were removed in the process. It isn't that much different with stone, the trick is making sure the footprint of the replacement is identical to or larger than that of the original. I've had budget-conscious clients that didn't care that the negative reveals were off on their replacement sinks in stone. Sink, faucet, soap dispenser, and disposal replacement, plumbing, top refinish and cleanup (ooo..it's messy) just over 3K. That's a Mirabelle sink made in Vietnam. Nice.
