Our sink is in our bay window, but I think the idea is the same, we continued the tile into a portion of it:

Hope that helps!

I think I just saw your kitchen in another thread on LED under cabinet lighting.

The above photos I cannot access it says the image has been moved or deleted... :-Our issue is to continue or not the tile all the way up to the ceiling (we have 9 foot normally, but 8 at this window because the corner at the ceiling is cut off) and into the bay window. Your window if I recall was not a bay window (the countertop did not extend into it).

Could you try to upload the pictures again? Thanks!
Also, what kind of backsplash tile is that in your kitchen?

Here is a link to a picture of our window:

sorry about that, I moved some pics around in my photobucket account and it broke my links...

Here is a pic of our bay window, ours looks a little different than yours, but hopefully this helps. Looks like your kitchen is coming along nicely! You can see more pics of mine and get details in the link below. Good luck!
