As of my last update in September 2021, I'm not aware of a Duravit "Zencha" basin series. It's possible that it's a new series released after that time, or there might have been a typo or miscommunication regarding the name. For the most accurate and up-to-date information, you might want to check directly on Duravit's official website or reach out to their customer service. If you have details or specifications about the product in question, I'd be happy to help craft a short description based on that information.
