Abstract: A backsplash structured to be cooperatively functional with a countertop structure. The backsplash is made of a plastic solid surfacing material, and possesses an integrally formed front bottom lengthwise edge extending outward from and beyond the front face of the backsplash to define a coved lip. The countertop comprises a normally elongated rectangular section of plastic solid surfacing material having an elongated dado. A bottom surface of the backsplash and coved lip is specifically sized and shaped for placement adjacent to and insertion into the dado of the countertop whereby a curved transition is defined between the top horizontal workspace surface of the countertop and the front face of the backsplash. The bottom surface of the backsplash and coved lip is affixed in place in the dado with the use of a color matching adhesive. Once the adhesive has set, the seam is finished with a light sanding with progressively finer abrasives.
