What tile are you using? Do you have trim pieces or bullnose tiles?

What are you using for the tops? What are you using for the backsplash?

It is hard to place slivers of tile in the narrow space between window and cabinets, and depending on the tile size/pattern can look odd.

Keep it simple.

Are your cabinets going to the ceiling with trim? If they are, you could tile all the way around the windows, but the narrow gap is still a problem with tile size/pattern.

I would tile half way up the window. Do you have an edge tile, or a chair rail tile? even a pencil or jolly to finish it off.

you could also remove the existing trim and trim out the window with wider trim to fill in the space between the window and the cabinets for a clean finish. I would remove the valance and install an inside mount blind or shade.

After having a huge kitchen done we decided the last decision was backsplash.
It honestly took us a month to find the backsplash.We probably looked at a dozen samples before deciding.
Good luck and please come back with photos when finished!

Thank you everyone. ceiling is getting redone and window treatments are old/ getting removed. I was thinking of a white ceramic 6 x2 tile or a white glass tile. countertop will be quartz calcutta and dont want the backsplash to compete with the countertop. i am doing white painted cabinets and base wood all with brass gardware like image beliw want clean lines easy on the eyes-open concept home

6” x 2” is a nice clean line - you don’t want tiny shards of tile. I like the idea of beefing up the window trim eliminating the need to tile the window sides, unfortunately, you have what looks like 3” on either side of the window, and adding 6” of trim to a small window can look weirdly inconsistent with the rest of the window trim in the room and house. remove the shades and add white paper to the sides of the wall - if it’s gonna look weird, you’ll see it.

The most conservative approach would be to tile straight across and use bullnose toles or trim to cover the tile edges in those 3” spaces. If your tile doesnt come with trim pieces you can ask your tile setter if he can mitre those areas. Good luck!

It's difficult to see in the photos. Did you stop the tile at some point or did you take it up to ceiling?

All the way up
