Quality Control


To ensure the quality of our sinks, Symbolsink team follows strict quality control procedures, according to cUPC certification standard, including full inspection and constant quality checks. Every sink is inspected when finished and second inspection before shipment. Sinks inspected by quality control officers are marked at the back of the sink to differentiate which has been inspected and which has not.
