A photo of the back splash can help a lot. Are these 4 inch square metal tiles? But yes on all three ideas you had.
Are they behind or installed up to the cabinet or vent? If you can post a photo I would be happy to post ideas as well as options. I am a interior designer and work for a general contractor. I love problems that make you think out of the box. Necessity is the mother of invention!
Linda heres the pics you asked for. thank you for any ideas!!!
