Yep, I'd say the backsplash is 'connected' to your cabinets, so usually would end with them. I have, though, seen it where people take it over to the trim, then run the tile all the way to the floor between the base cabinet and trim.

Beth H. : Thank you for your suggestions & photos. I will ask our tile guy if they'd be able to do some kind of casing for us around the window. I wish our kitchen window had either a straight rectangle on top or a real arch like the photos you posted. The top window is tricky for me to conceptualize what it would look like without molding. I thought about encasing the whole window with two vertical pieces on the left and right side but the middle piece that separates the top window from the bottom window would be strangely thick. At this point it may be easier to just bring the tile to the red line and add a roman shade over the top of the bottom window but I'm not 100% sure yet. As for the tile, we are doing the plain subway tile pattern. I thought about herringbone for the backsplash but my husband and I love the classic look. We are weird with patterns and not gutsy enough to try anything bold lol. Our kitchen has a lot of white in it and we went with honey/light cinnamon colored floors to keep it very neutral. I change color schemes at least once every two months so it made sense to keep it very neutral for us.

Your first photo shows an outlet, not a switch. If it can't be moved to the left, leave it where it is and hold the backsplash back a couple inches from the cover plate. The fact that the backsplash doesn't go all the way to the end of the counter won't matter.

Here's what I would do, though a lot of this is just personal preference (and budget): •To the right of the window: I'd take tile to the edge of the counter and same height as the bottom of the cabinet. Going all the way up would look nice too but more costly. •On the peninsula: Either stop the tile even with the edge of the top cabinet or go to the edge of the wall (in both cases, up to bottom of top cabinet). Pros and cons to both since you have that sliver of wall that runs up next to the cabinet, so just see what looks right to you. •The stove wall: Stop the tile in the right back corner. Wrapping the corner introduces a whole new set of decisions to make and I don't think you need to. (If you decide to, though, I'd run it to end at the edge of the counter.) •To the left of the stove: Stop even with the bottom of the hood since there's no counter on the other side and it looks like your hood edge is flush with your stove edge. Move the light switch over to clear the backsplash (or maybe somewhere else entirely, depending on what lights it controls). •Tile inside open cubby where microwave is: Just the back, or no tile at all. Wrapping the side is going to leave an odd slice of drywall between the tile there and the tile above the stove. Some of this you may just need to figure out as you go and see what looks right--dry fit everything before you start so you can see what is looking off to your eye. Good luck!
