The setup of a concealed cistern system for a bathroom, typically used in modern wall-hung toilets. The plastic cistern is mounted within a framework of perforated blocks, which will later be covered by wall panels. Plumbing pipes for water supply and waste drainage are organized neatly on the floor, with hot and cold water supply lines (red and blue) leading to the necessary fixtures. The framework provides a sturdy base for the cistern and facilitates a clean, streamlined look in the final bathroom design. This setup is efficient and maximizes space in contemporary bathroom layouts.
