As of my last training data in September 2021, I'm not aware of a "Duravit Soleil by Starck Basins" product line. It's possible that this is a new product line released after my last update, or there might be a mistake in the naming. Duravit has collaborated with Philippe Starck on several bathroom collections, but the "Soleil by Starck" wasn't one of them up to that date. For the most accurate and current description, it would be best to check Duravit's official website or contact the company directly. If you have other questions or need descriptions of other products, feel free to ask!
