Abstract

A built-in sink unit with at least one basin, which has first surface areas, such as the bottom of the basin, subject to severe wear during use as well as second surface areas, such as the side walls of the basin, subject to less severe wear during use and in which the first surface areas are provided with a three-dimensional surface structure and the second surface areas are smooth. To ensure that any surface damage in the region of the surface areas subject to severe wear during use does not immediately catch the eye, the built-in sink unit gives the optical impression, when new, of really being a new article and the sink unit can, finally, be cleaned effectively with abrasive means without any disadvantageous optical effects thereby resulting, the surface structure of the first areas is formed by microgrooves at least approximately straight and extending parallel to one another, the surface roughness measured transversely to the longitudinal direction of the microgrooves being greater than 0.1 .mu.m and at the most approximately 0.4 .mu.m.
