I would definitely support changing out that back splash. Without seeing anything more than these pics, white-ish subway tiles would be a big improvement.

White subway will be classic and beautiful...look at some of the new beveled or textured designs to add interest.

Something like our below design? It would most likely look wonderful.

I agree with everyone else - the subway would look great.... and if possible get rid of that short black backsplash - it will make a big difference.

Good luck!

The subway tile would look good! If you are looking for a different pattern. The Herringbone pattern would look great too and be classic!
