If possible, please post your layout. It is so difficult to give any opinion without a visual - for me anyways :)

It doesn't make sense to simply replace the clean-up sink with the stages sink. The out of the way location makes sense for a clean-up sink and is sort of the worst possible place for a prep sink. Imagine you are cooking, and whatever's in your pan is browning rapidly, and you realize you were supposed to add an extra ingredient before it finishes. You're going whip around that island to the prep area to grab that extra ingredient and whip back. How many times will that happen before you injure yourself running into the island? Or run into somebody else?

It would make sense in terms of use and location to replace the prep sink with the stages. But then you are using nearly all your island for that.

I would suggest posting your layout again and asking how it could be reworked for the stages to make sense for you. Things are going to have to move around a lot more than simple swap you're proposing.

If your island is in the way of the fridge-sink-range path by more than 12", you need a prep sink on the island. Period. See the illustration in Rule #3: http://starcraftcustombuilders.com/kitchen.design.rules.htm#.VQrx447F_II

What about a kohler stages 33 in the island as a prep sink and a regular sink for your clean up sink?

Not every kitchen needs a prep sink, but one that has a very large barrier island between the other sink and the cooking area does!

Here the basic layout, with kitchen in lower right, but there have been some changes. A steam oven was added to the right of the range, pushing the range a little to the left. The pantry sink is just to the right through the door (on the wall behind the fridge). This is a similar setup to what I had for 15 years in my last house (with a sink in my butler's pantry) and I managed to not injure myself or anyone else during that time. (I cooked professionally for years so am fairly competent and well organized when I cook.)

The Stages 33 is an interesting idea. Running now but will look at this carefully (including your link, tracie erin) when I get home. Thanks to all for the advice. (You all talked me out of a two compartment sink and, shall we say, helped set the stage for this. ;) )

If you'd like your island uninterrupted, could that wall along the right side of the cooktop hold a prep sink? I really don't think you'd want to do all your prep sink work way over there across from the sink, fridge, etc. And what about draining a pot of pasta water . . . Yikes. The idea of your desired prep sink (Stages or whatever) being somewhere near the main part of the kitchen is a great one. Then you could put a simpler large single bowl as your clean up sink.

So, after some thought I'm leaning towards the smaller Stages on the island and a separate clean-up sink under the window.(Thx, crl!) This would leave a nice 3' x 3' section at the end of the island for baking tasks. The 33" Stages is almost like having a 16" built-in cutting board adjacent to a 16' prep sink. Thoughts?

szruns, thinking you're looking at the peninsula? It could be pressed into service during prep but will mostly serve as a buffet for the dining room, with a cherry top.

A friend who was over this afternoon pointed out that, with the prep sink on the island I have a pretty self-contained workspace where I can "hold court" while I work during a party and also duck around to the pantry sink if I need to stash a dish or two, keeping the passage way between the dining area and the kitchen table clear. I like that.

The Stages is the ultimate prep sink. I think your current plan to use it on the island and get a regular ol' cleanup sink under the window is good.
