Abstract: Shape structure or mold usable to form a desired wall surface includes a first region constructed for being attached to the wall; and a second region constructed for being located in an opening formed in the wall. The first region may be constructed as a flange and the second region as a body. The body may be constructed to form either a recess or protrusion when placed in the opening of the wall. An inner surface of the body is formed with plural recesses. The mold may also include a third region for fastening to the wall, and the wall may be a shower wall. A process of forming a desired wall surface includes the steps of forming an opening in a preliminary wall; fastening shape structure within the opening; and finishing the shape structure and preliminary wall to achieve the desired wall surface. The fastening step may include the substeps of locating the shape structure within the opening, and attaching a region of the shape structure to the preliminary wall.
