An appliance includes a cabinet defining at least one chamber accessible via an opening. The appliance also includes a cover member movable between an open position and a closed position for providing selective access to the opening. The appliance includes a hinge assembly constructed of a polymer material and operably coupled to the cover member. The hinge assembly includes first and second hinge members. The first hinge member is fixedly secured to the cabinet. The second hinge member includes a base portion fixedly secured to cover member and a pin portion. The pin portion is rotatably secured to the first hinge member to move the cover member between the open and closed positions.
