The bowl portion waste receiving surface includes an upper waste receiving surface connected to the rim portion, and a concave portion connected between the upper waste receiving surface and the discharge trap pipe. The concave portion includes a bottom surface connected to the discharge trap pipe and is positioned below the upper waste receiving surface, and a wall surface connecting the bottom surface and a bottom edge portion of the upper waste receiving surface.
