Wall paneling includes a pair of corner panels, a center panel, and pair of end panels, each of a molded unit construction. The corner panels have a pair of right-angular walls and the other panels are flat. Each of the end and center panels have upright marginal enlargements terminating in edge flanges. The inner enlargement of the end panels and both enlargements of the center panel adjustably overlap and receive therein a corresponding portion of a wall of a corner panel and are coplanar therewith respectively. The end panels extend at right angles to the center panels. Adhesive is interposed between the overlapped portions of the end and center panels and corresponding corner panel. Said paneling may be used for covering the end and back walls of tub enclosures.
