I've checked out as many pictures of recessed niches/shelves over ranges as I could find, but am still feeling uncertain aobut whether what I have in mind will look right or not. I'd really appreciate some feedback.

My kitchen-in-the-works will have a 36" stainless capital range, with a 36" wide stainless cabinet-mounted hood above (30" from top of range to bottom of hood). On either side, there will be two 9" wide open shelf units (20" above counter top). I'm contemplating having a 3" deep niche essentially full width and nearly the full height of the area above the range. I say nearly the full height, because the range has a squarish metal piece about 2.5"-3" wide and 2.5"-3" high running across the back. I contemplate making the niche start just above this and installing a 5"-6" wide piece of soapstone in the bottom of it, forming a shelf that will extend 2"-3" out from the niche. I do hope this is a clear description!

I haven't seen any pictures of full-width niches that are bordered on either side by upper cabinets and am wondering if it in fact will look OK?

Also, I'm planning a pot filler faucet and wonder if the extra 3" depth will cause a problem? Of course, I'll have to make sure the faucet spout is long enough to reach the pots, even with the extra depth, but am wondering if I'm overlooking some OTHER issue. What do you think?
