The Home Decorators Collection 21.13 in. W x 0.75 in. D x 3.5 in. H Stone Effects sidesplash in pulsar helps protect bathroom walls from splashes and damage. This 3.5 in. H sidesplash is finished on the front and edges with rounded corners and a flat edge design for a professionally finished look. Made of cultured marble with a pulsar finish, this splashguard features dark purple-gray veining and speckling on an off-white base for a granite-look. 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 sidesplash is quick and easy to install on top of a floating or freestanding bathroom vanity with a 22 in. D Stone Effects pulsar vanity top. Its universal design allows it to be installed on either the right or left side. 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.
