Abstract
A dishwasher tub includes a main body having opposing side walls that are interconnected by a rear wall, all formed from a multi-layered composite material. A cap member is joined atop the opposing side and rear walls, a base member is joined to lower edge portions of the opposing side walls and rear wall, and a frontal halo member is mounted between the cap and base member to define an overall washing chamber having a front opening. Preferably, the multi-layered composite material includes an inner stainless layer, a rigid layer and an outer protective layer, such as a layer of stainless steel, a rigid polyester mat, and a protective layer of hard plastic or aluminum foil. The outer layer also preferably serves as a shipping container for the dishwasher, enabling components of the dishwasher to be transported to a designated location for final assembly.
