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.

Malhgold...your comments..."I'm never really sure when people say keeping the "snack items" in the frig drawers what that really means. How many juice boxes and yogurts can one have that will make the best use of those drawers. My kids are older than yours, 12 and 9, but they want to pick and choose from the entire frig, not just what snacks I might want in the drawers." might have just sealed the deal in that better prep location is more important than better snack location in our situation. So the range end is probably best. You are right...what kid wants to choose only from a limited selection when they know you have a whole other fridge full of things. I think they get wise to choosing from only an edited selection very soon! I will still post a layout later tonight and see if something else jumps out. I appreciate the feedback from you moms of older kids. Its already going by so fast I know mine will be that age soon!

First, without actual dimensions and a layout, we cannot say one way or the other if it's feasible in your kitchen. In general, though, ask yourself... What will the island add? Will it add functional counterspace? Or is it just something you "want" b/c you like the look of islands? Is your kitchen wide/long enough for adequate aisles around the island? If not, it can cause traffic congestion (like Flwrs_n_co discovered). This traffic congestion can be through traffic, traffic in work aisles, or space in the work aisles in general (room to work). Will the aisles be wide enough to use your appliances (refrigerator door(s), open DW, etc.)? Will the island be a "barrier island" (b/w the sink & refrigerator, b/w the range & refrigerator, or b/w the sink & range)? If it's a barrier, you will have to run around it to go to/from the zones it's between. If you want seating, remember that you need room for the 15" overhang + 45" to 48" of aisle behind the island for both seats & traffic. If there's another workspace or appliance(s) behind the island, you will need 48" to 54" for that aisle. If it's a "dead end" area with no outlet and no appliances or workspace behind it, then 36" is probably all you need behind the island for people to squeeze past. I also really wanted an island (w/seating) in my 11' wide kitchen, but I was lucky enough to find this site and have several honest folks here tell and show my how an island just wouldn't work b/c my kitchen was too narrow. I am very grateful to those people and I ended up with a kitchen (sans island) that's wonderful to work in! I never would have had that if I had insisted on an island. My DH & I still occasionally comment on how we're so glad we don't have an island!

I think I would look at installing an outlet strip on the side facing the dishwasher (on the horizontal strip supporting the counter); the wiring would come up through the floor inside the island and then across the underside of the butcherblock.
