Using your Duravit Durasquare Vanity Sink is easy. Just install a single - faucet on the available hole. For daily use, you can wash your hands, brush your teeth, or do other basic bathroom tasks. When it comes to cleaning, use a mild soap and a soft cloth. Avoid using abrasive cleaners as they can scratch the surface. To maintain its shiny look, dry it with a clean towel after each use. Also, don't put heavy objects on the sink edge to prevent any damage. If you notice any water stains, a gentle wipe with a vinegar - water solution can help remove them.
