The Geberit Omega Top/Front Flush Concealed Cistern is a modern toilet installation solution designed for compact bathrooms and streamlined pre-wall installations. Part of the Geberit Omega collection, it features a rectangular white plastic construction with a slim 120mm depth, helping make efficient use of available space. The cistern measures 315mm high and 416mm wide and is designed for an installation height of 820mm. Its concealed mounting keeps the cistern hidden from view, creating a neat finish around the toilet area. Suitable for drywall construction, this cistern is intended for use with floor-standing WCs and offers a practical solution for contemporary bathroom layouts. It comes with a 10-year guarantee.
Designed with top or front flush actuation, the Geberit Omega cistern provides flexibility when planning the installation and can be paired with compatible Geberit Omega flush plates, which are not included. Its dual-flush mechanism has factory settings of 5.8 litres for a full flush and 3 litres for a reduced flush, with adjustable volumes available. Full insulation helps prevent condensation, while tool-free installation and maintenance simplify servicing through the protection box. The package includes an R 1/2-inch water supply connection with an integrated angle stop valve and hand wheel, a cut-to-length service-opening protection box, flush bend extension and fastening, protection plug, two fixing brackets, mounting materials and a Geberit pull disc for a Type 212 flush valve.
