I added a hood above the range. It originally had nothing and then a homemade vent hood and it was greasy and sucky.
After adding a hood, I needed more backsplash tile up to the hood so that the grease from the cooking surface can be wiped down. I decided to make it match the bathroom tile I extended up when I raised the shower head.
I used "natural grey" grout so hopefully it'll match the old stuff and look good behind the wedgewood.
