Abstract: A toilet has an open top, a bottom positionable on a floor, a front, a rear and laterally spaced sides. A water passageway through the toilet is in a generally S-shaped configuration with a generally central P-trap. A cutout in the rear of the toilet has a vertical exterior edge, a vertical interior edge, a generally horizontal lower edge and a generally horizontal upper edge, the edges together forming a continuous bearing surface. A removable panel is shaped generally as a mirror image of the toilet between the upper and lower edges of the cutout and has a continuous bearing surface positionable to overlie the bearing surface of the cutout. Mating flanges are on the panel and the toilet adjacent to the bearing surfaces. Bolts with nuts extend through the holes in the flanges to allow separating the panel from the toilet.
