Monolithic molded ceramic countertop with acid-proof glaze glaze, with molded marine overlay edge of the same material, on one or more edges (optional). Acid-proof coating covers top horizontal surface, the edges of the worktop (optional) and the edges of the recesses for sinks. The worktop can withstand various but limited cuts and/or technological holes (optionally glazed). Furthermore, sinks can be incorporated with the same properties, mounted in various ways: on the countertop, flush with the countertop, or hidden (under the countertop).
