Abstract: A tub construction for a dishwasher is provided. The tub construction includes an upper panel, a lower panel disposed below the upper panel, and an intermediate panel perpendicularly connecting the upper and lower panels. The tub construction of the present invention not only allows for a quicker assembly of the tub, but also an easier changing of the tub's outer dimensions. Furthermore, when seam welding, by changing the dimensions of the flanges at the corners, wrinkles at the corners are prevented, creating an even, leak-proof welding line.
