Using your Duravit No.1 Wall - Mounted Bathroom Vanity Unit is a breeze. First, make sure the plumbing is connected properly through the siphon cut - out. You can then start filling the pull - out compartment with your bathroom essentials like toothbrushes, toothpaste, and soap. When it comes to maintenance, use a soft, damp cloth to wipe the surface regularly. Avoid using harsh chemicals as they might damage the finish. For the pull - out compartment, check the tracks occasionally to ensure smooth operation. If you notice any issues with the plumbing, it's best to call a professional. With proper care, your vanity unit will serve you well for a long time.
