ABSTRACT:
A shower stall tray includes a plastic shell defining an outer surface and a cavity that is filled with a light weight resinous material and a structural member having a density less than the resinous material. The plastic shell is formed to include a visible surface and a backside surface. The backside of the plastic shell defines an open cavity that is filled with a resinous material. The resinous material provides structural rigidity and the solid substantial feel providing a favorable perception of quality. The structural member not only provides structural support for the shower tray, but also displaces resinous material, thereby reducing the amount of resinous material required to fill the open cavity.
