We went back & forth between a 36" vs 48" Wolfe range & ended up with the 48". It fit our design better and we liked the option of 4 burners and 24" of grill/griddle space. We still needed more oven space (the holidays) & ended up with a Miele Speed oven (convection/microwave). Wolfe also makes a convection/microwave wall oven (too big for our layout). You might also want to look at the Wolfe Steam/convection oven.
Subzero has a whole new line of refrigeration. The units we purchased have been discontinued. We got a generous discount by purchasing both Subzero & Wolfe. We like our units but my only comparison is to a 17 year old Frigidaire.
Do you have a layout? Some of our choices were driven by what we had room for.

Hi romy718,

Here is a draft layout of my plan. Other than shifting the middle island slightly and giving it that extension on the bottom end, this is the footprint of the existing kitchen, which is dark and not optimally functional. To give you an idea of the current space, the island on the lower right (with a designation "prep sink?") is where my kitchen sink is now, which is approximately 15' away from my cook top. My oven and microwave are inserted into the top left corner taking up an inordinately large amount of counter space. By moving my sink I gain functionality, and even though I lose the upper cabinets that are on the existing wall to a new window, I gain light. By moving ovens I gain counter space. I lose my desk, but there is still a space for dropping stuff off, which will be smaller and thus I hope it will make for less of a visual eyesore.

I am also most likely to use a 42" refrigerator and thus won't need the refrigerator drawers.

As for size, the long refrigerator wall is ~17', the range wall is a little over 13', and the wall where the sink goes is ~12'. The bottom side opens to the family room and the lower right opens to a breakfast room, which will remain untouched.

Any comments on design? I have the room for the 48" range, I'm just not sure if I want to give up that nice large oven on the 36" range. What about the oven stack right next to the fridge, versus having (left to right) fridge then pantry then oven stack then drop-off place?

Thanks to all.

Don't forget to work ventilation into your comparison shopping, venting for a grill and/or a 48" range will likely cost much more (including cost of make up air) than venting for a 36" range.
