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.

Hi Laura: My island is dark cherry, and also has furniture ends that I did not want to damage with unsightly outlets. I have seating on one side, and put an outlet on each side of the seating "kneehole" space, up as high as possible. We used brown outlets and covers, and you do not see the outlets unless you bend down to look. I have not found this to be a problem with access, and prefer the small extra effort needed to access the outlet (occurs once in awhile) over the look of seeing the outlet on the cabinetry (would see it all the time). The location actually works quite well in terms of not having appliance cords trailing across the island top--especially if someone wants to sit at the island and use a laptop--which seems to be the primary use of island outlets at our house. I generally do food prep on the perimeter where I have immediately accessable outlets, so the island ones are not as key for usual kitchen chores, which might be a consideration--if you use your island more for food prep.

well I guess the beauty of reading these forums is you really do get some great visuals. In Scott's new kitchen, the photo shows that it looks quite nice with just 2 pendants around the sink.https://www.gardenweb.com/discussions/5730930/heres-my-new-kitchen#comments

Who knows what happens in the future.. I think the structural laminate panels make a terrific looking counter particularly for a modern aesthetic---which is what I assume the OP is seeking given that OP wants a 3/4" counter and a waterfall. I mentioned it as an alternative because no one else had suggested it. And because it can have a life after it serves as a counter. With stone, not so much. There just isn't much use for a discarded stone or quartz countertop. Beyond tossing it in a canyon for erosion control. Not that you will be tossing it. More like rolling it over the edge with the help of your friends.
