The hood needs to be 6” wider than the range, both for functional purpose (6” wider means best capture area for the cooking grease and smoke), and for aesthetic reasons (the hood looks too puny over the range when they’re the same width). The hood also needs to be deep enough. Many of these types of hoods are only 18-19”deep, while the range beneath it will be 26-28” deep. Make sure to specify the correct hood depth of at least 24”.

”We are locked into this placement of the range because we want it centered with the island in front of it.”

This is one of those knee-jerk modes of thinking that doesn’t make that much sense. The range will only look centered to the island when you are looking at it straight on. But if you are looking at it from a few feet to one side or the other, you can’t tell if it’s centered or not. I am not against centering the range to the island; I just wouldn’t jump through hoops in that effort. If you will have a second sink in the island, make the sink offset. You don’t want people at the sink and at the cooktop having to brush behinds.

I would not do floating shelves near a range. The shelves will need to be cleaned a lot in that location, and could appear cluttered if not careful about what you put on them.

probably wise to show the overhead including the island.. you may want scrutiny about aisles etc. I'd skip the "down to counter " cabinet. I'd move range to the left . so along w comments about the hood above this means a bit of a redo of this wall. Make your adjustments while you are in planning mode. The looks and aesthetics of floating shelves and sconces should be lesser priority than getting countertop runs proper/ appliance placment issues sorted/ and the logistics of venting / aisles etc........

Here’s the overhead.

So, you are either passing the range every time you go from the sink to the fridge, or walking around a large island? How many cooks in this kitchen? My kids would drive me crazy in 1 day because they would be in my prep area all the time...they go to the fridge 1,238 times a day...sometimes just to stare at it waiting for a meal to jump out. Have you considered adding a prep sink to the fridge end? Yes, it would be off set and the faucet would not be lined up with your hood and range.

Edited: I would make your hood 42" wide, it will look and function better. The 28" empty space on the sides is not a problem...I have a chimney hood and the bottom has 24" to the nearest cabinet (down to counter) and the top has 39"... the other side has the same distance to a window that goes down to the countertop.

Mostly one cook. The fridge is on the end of the range wall so they can get in and out of there without disturbing the cook prepping on the island or cooking. Thanks for the feedback.
