1. A casting in the form of a sink, comprising a basin having a base, a rear wall, a front wall and two interconnecting side walls, and also a circumferential rim that extends to the side of the basin and consists of flat rim sections that extend in a straight line from the lateral edges of the rear wall, the side walls and the front wall, wherein the sink consists of a composite material comprising a cured polymeric binder and filler particles intercalated therein, wherein a skirt that surpasses the height of the front wall at least in sections adjoins at least the rim section of the front wall, wherein the skirt has an outer face that extends at right angles from the outer face of the rim section of the front wall and in a straight line up to the end of the skirt, wherein the skirt has an inner face that runs at an angle to the outer face so that the skirt narrows in thickness towards its end, wherein the skirt narrows in thickness from top to bottom over its entire height, wherein the skirt consists of a middle skirt section that extends along the front wall and two lateral skirt sections that merge into the rim sections of the side walls in a rounded manner, adjoin the lateral edges thereof and are at right angles to these rim sections, wherein the middle skirt section narrows more than the two lateral skirt sections, wherein the middle skirt section narrows at an angle between 0.5°-1.5°, and wherein the lateral skirt sections narrow at an angle between 0.1°-1.0°.
