Transform any small bathroom or cloakroom into a fully functional space with the addition of a concealed dual cistern to any space. The Geberit Sigma 8cm Slimline Concealed Dual Flush Cistern is a space-saving cistern that is ideal for places where space is limited. This cistern only requires a minimum of 80 millimetres of space for insulation. The water supply connection is located at the top with the offset hose on the left hand side and comes with an adjustable flush bend that can be adjusted to 2 centimetres upward and 1 centimetre downward. This setup makes it easy to perform emergency repairs without disrupting the surrounding walls or structures. Avoid disturbing the household with the included adjustable flush volume. This Geberit concealed cistern is compatible with Geberit's Sigma, Dance and Mambo flush plates or flush actuators.

Cistern and other items arrived on a pallet extremely well wrapped and protected. Cistern is very well made with numerous clever features that enable to be installed with relative ease. Very happy and glad I chose a Geberit cistern.
