The Geberit concealed installation system – also known as an in-wall carrier – allows you to design and create the bathroom of your dreams. In-wall carrier systems allow designers to create eye-catching new bathrooms from the bare minimum without expensive structural work. The frame system can be used in the tightest of spaces including corners, allowing designers the freedom to create stunning bathrooms without compromise. Because the carrier includes an integral water tank located behind the wall, the resultant aesthetic is a clean and modern finish with no visible pipe work. Only the attractive decorative actuator plate attached to wall remains visible.
