A warewashing machine has a washing chamber with an enlarged height to increase the chamber's capacity without increasing the warewashing machine's surface area, and has collapsible doors to facilitate larger openings to the enlarged washing chamber. The larger openings and enlarged capacity allow the warewashing machine to wash oversized wares. The collapsible doors allow the full access to the enlarged openings without significantly increasing the minimum height of the ceiling over the warewashing machine. The warewashing machine door also includes a pivoting handle with an downward curving arcuate section to allow the operator to easily reach the handle when the door is fully opened.
