I have seen tin backsplashes melted behind gas stoves, so be cautious about where you are placing this. While I have never specified a kitchen tile backsplash only partially up on the wall, if you do this make sure to have it look intentional. Such as having it follow the height of where maybe the sink window cuts the backsplash off. Also use a trim piece; a pencil tile or some type of architectural tile to cap the top. Best of luck in your selections and installation.
