The Veil smart wall-hung toilet offers integrated personal cleansing while saving up to 8 inches of precious bathroom space over KOHLER''''s longest floor-mount models. This Veil toilet requires the K-18647 in-wall tank to complete the system. The mounting hardware is concealed, giving Veil a sleek, seamless look that is incredibly easy to clean. Its sculpted core delivers a suite of precision features finely tuned to provide optimum hygiene and ultimate individual comfort, from personal cleansing to an LED nightlight to hands-free opening, closing and flushing. All of the features are easy to control on a touchscreen LCD remote control. In addition to the remote, you can control the Full and Eco flush using the touchless, Honed White actuator plate (included).
