Practically speaking, a backsplash performs two functions: It protects walls from grease and water splatter, particularly behind a sink or stove, and provides a resilient surface that can stand up to periodic scrubbings. But a beautiful backsplash is also an opportunity to tie together the other finishes in your kitchen. “Your backsplash can really be eye candy and a chance to add in some textures and patterns,” says H-Millard. In an ideal renovation, your backsplash will serve all three functions.
