I’m thinking just tile to the upper cabinets on both sides of the window. I would fit a piece of counter material behind the sink.

Lol, that said, in our kitchen which we just finished, we tiled in a chevron pattern to the ceiling, even over the window, but we have no upper cabinets. We fitted a piece of our quartzite behind the sink up to the window sill (about 4 inches high).

One suggestion, try to match your outlets and covers to your tile color. Lutron and Legrand have wide ranges of colors—most available on Amazon or Home Depot websites.

good luck! J.

p.s. Beautiful kitchen!

I think your'e overthinking it. When did a backsplash become "wallsplash" or window trim? (That's my rhetorical question, not directed to you specifically.) We have a window like yours and it is simply trimmed out in wood with oil based paint, NO water sits on wood, no problem. Beautiful kitchen and with the window cased out, it will be nice.

Depends on the size of your tile. I used a 3x6 tile in an offset pattern with a looser grouting all the way to the ceiling around my window and all the way under my cabinets. It’s all just based on the finished look you want.

Tiling entire walls has become a popular thing if you look at design publications in the last few years, however, that area around the window is going to be tricky for getting the small pieces cut and fitted to look good. If you go with quartz on the wall, take care that your fabricator could do it with the slabs you've already reserved, because it usually isn't worth the cost to go over to an extra slab just to get the backsplash done. If you do have enough available excess quartz, however, doing the backsplash in the same material is always a nice look. You'd want to move your electrical outlets up to underneath the cabinetry with a Legrand Adorne under-cabinet system most likely if you did quartz there. As a previous commenter alluded to, most full-tile walls in kitchens are done where there is less wall cabinetry than you've designed for your space. Wallpaper has been making somewhat of a comeback in trends if you wanted to do a special pattern over the wall but without the thickness of the tiling.

I have a similar situation and tiled to under cabinet height on both sides and used a piece of counter top for a nice window sill.

Here's another idea, tile behind stove, behind sink and paint the rest. I am thinking once the window is cased, you probably won't need any there.

Up to the hood if the hood fits cabinet-to-cabinet, up to the cabinet bottoms, and up to the window trim. At the far right, I would tile up to match the level of the cabinet bottom on the other side of the window to keep it looking balanced.

Here’s an idea.

To clarify: the window frame matches all of the window frames in the house. None are cases and we don’t plan on putting a casing on them. Maybe we could put a case on just the kitchen window and leave the rest as is? Would that look funny?

The gap where the hood will go is 34 inches wide, so the hood will not fit cabinet to cabinet. That’s why we were thinking we would tile to the ceiling in that area. The gap where the stove will fit is 30 inches wide, BTW.

It looks like there is casing around your door? A bit hard to see but looks fairly flat and wide, what is it? 1x6? I'm thinking that having similar around your windows (1x4) would be expected not funny looking.

Did you finish your backsplash? I have windows without casings, too. (before demo pic) and plan on keeping stone window sill.
