Abstract

The present disclosure provides embodiments of a kit for supplying reinforced porcelain panel products for use in shower enclosures. In an embodiment, a kit includes a container and one or more reinforced porcelain panel products positioned to be associated with a container. Each of the reinforced porcelain panel products includes a) a porcelain slab having a top surface with a first surface area, and b) a structural core board including a foam-core material and having a second surface area greater than the first surface area of the porcelain slab. The structural core board is positioned in abutting contact with the porcelain slab with adhesive material therebetween. The structural core board extends beyond outer peripheries of the porcelain slab to be visible and to enhance protection from cracking when the reinforced porcelain panel product is handled and is further to be attached to a mounting surface when installed.
