Using your Duravit Happy D.2 One - Piece Toilet Kit With Seat is easy. Just use the flushing handle as you would with any regular toilet. The innovative flushing system will do its job efficiently. For daily maintenance, simply wipe the smooth surface with a mild bathroom cleaner to keep it clean and prevent bacteria buildup. When it comes to deep cleaning, make sure to turn off the water supply first. Then, use a toilet brush to clean the bowl thoroughly. Avoid using abrasive cleaners as they may damage the surface. And that's it! With proper care, your Duravit toilet will serve you well for a long time.
