I would not go all the way up with it on the pass through wall, but that's just my opinion. I'm not a pro so I'd be interested to hear what they would say.

I agree with Cecilia. Just follow the cabinet height straight around. You have enough wall space that painting the rest will look fine.

Then, you have choices for the hood. I like going all the way up but....it looks like it will go past your cabinets up there, so I’m not entirely sure.

The other choice is to tile up to the bottom of the hood.

When we put in this kitchen, we needed the cabinets to be as big as possible. That left tiny slivers of wall on either side. Our painter painted it. I had him change it to white, so that tiny sliver blends with the cabinet.

You have a decent amount of space there.

Forsure go all the way up.

My first reaction is to tile up around the pass through also as you said in another post that you’re doing behind hood because I think it highlights that interesting feature too. My opinion is partially based on your tile choice which I understood is a simple design such as subway style. I don’t know if the curved shape presents challenges with tile layout though & knowing that would sway my decision. I’m interested to see what Pros have to say.

Yes, am going with very simple splash all the way around -- likely a 4 x 8 but considering 3 x 6 (will cut out some poster board rectangles and tape them to the wall to see which way to go).

I think it looks funny since your cabinets don't go up to the ceiling. Are you able to change the cabinet crown molding to go up to the ceiling?
