The Home Decorators Collection 21.13 in. W x 0.75 in. D x 3.5 in. H Stone Effects backsplash in lunar helps protect bathroom walls from splashes and damage. This 3.5 in. H splashguard is finished on the front and edges with rounded corners and a flat edge design for a professionally finished look. Universal in design, this sidesplash can be installed on the left or right side. Made of cultured marble with a lunar finish, this sidesplash features dark gray and maroon veining and speckling on an off-white base for a granite-like look. And its smooth, nonporous finish makes it resistant to mold, mildew, and bacteria. And its Diamond Shield Surface Coating, a marine-grade gel coating, provides a smooth, easy-to-clean surface with enhanced wear- and stain-resistance, giving you the look of natural stone without the extra maintenance. This set-on backsplash is quick and easy to install on top of a floating or freestanding bathroom vanity with a 22 in. D Stone Effects vanity top in lunar. Simply apply a thin bead of silicone to the back of the sidesplash and secure it to the wall. The rear side of the sidesplash should sit flush against the backsplash and the bottom side should rest directly on the vanity top. A bead of silicone to seal the bottom completes your installation.
