The classic in modern bathroom installations

Geberit concealed cisterns are the classic of modern bathroom installations and have been installed a million times over around the world for more than 40 years. They are known for their proverbial reliability. Every cistern is pressure tested before dispatch. The 25-year spare parts availability and the 10 year warranty on cistern tank and frame provides long-term security.

Geberit concealed cisterns


A suitable model for every construction situation

Suitable model

Whether it be drywall or solid construction, whether new construction or renovations: With the Geberit Duofix, Geberit Kombifix, Geberit GIS and Geberit Sanbloc installation systems, Geberit always has the right solution ready for a concealed cistern. A wide range of special models enables utilisation in unusual building situations.


Quality behind the wall

Durable polyethylene

The Geberit concealed cisterns are made of durable polyethylene (PE). They are produced in the blow-casting process from a single piece without seams. After the flush bend is welded on, each cistern is tested at a testing station for hundred-percent tightness. More than 60 million installations and 50 years of experience on the market speak for themselves.


Aesthetics and design

Set accents

With the concealed technology from Geberit, everything that belongs behind the wall goes behind the wall. Only the actuator plate remains visible – and it is available in a variety of versions. This allows you to set accents in the bathroom.


Maximum stability

Installation systems

No wobbling, no vibration: The Geberit installation elements for wall-hung WCs can bear loads of up to 400 kg. The installation of the WC ceramic appliance takes place on the steel frame of the installation element which withstands these loads day in, day out.


Easy to care for

Wall-hung WC ceramic appliance

Geberit installation systems enable the installation of a wall-hung WC. Tripods and exposed cisterns are dispensed with, which means that there are no longer any places of difficult access and that cleaning is made simpler.



For 50 years

It lasts and lasts and lasts – and has been doing so for 50 years: More than 60 million installed Geberit concealed cisterns are the best evidence of their durability. Because these products function so well, Geberit provides spare part security for all function-relevant components for at least 25 years. Spare parts are also currently available for concealed cisterns that were shipped 35 years ago.


Simple maintenance

Simple and fast

Everything from Geberit is part of a well-thought-out system. That means that any maintenance work required can be accomplished simply and rapidly. The retrofitting for new technologies, e.g. for saving water or for fitting a shower toilet, can also be accomplished without difficulty in many cases.


Forward-looking innovation

The toilet of tomorrow

Geberit concealed cisterns are always a bit ahead of their time, because Geberit is already thinking today about the toilet of tomorrow. Special preparations enable the utilisation of forward-looking applications, e.g. of a shower toilet, of the Geberit DuoFresh odour extraction unit or of a touchless actuation.
