Geberit’s innovative concealed cistern technology and button designs has allowed users throughout the world to experience the luxury of well-designed modern bathrooms. Modern bathrooms reflect simplicity and style. With experience spanning more than 50 years, Geberit has developed an eye for premium button designs.

Geberit concealed cisterns are a reliable, hygienic and efficient bathroom solution hidden behind the wall to provide significant space gains. They are made from one-piece blow-moulded technology and use high-density polyethylene (HDPE) to ensure that the cistern is permanently leakproof. This has led to the installation of more than 70 million concealed cisterns worldwide.

Geberit offers an impressive 15-year warranty on cistern tanks and frames as well as 25-year spare parts availability for ultimate peace of mind and long term security. Outstanding product quality is only achieved with a team of Geberit engineers and designers who have a passion for innovative function and design. Precision Swiss engineering and outstanding manufacturing combine to deliver peace of mind behind the wall and design freedom at the front of the wall.

To ensure its carbon footprint is responsible, Geberit puts the environment at the heart of its business by focusing on sustainable sourcing, manufacturing, logistics and product design that delivers a harmonious synergy with nature.

Everything with a system – Geberit flushing systems

Geberit provides reliable, discreet behind-the-wall solutions that ensure perfect functionality, outstanding convenience and maximum durability. The buttons are the only visible elements of a concealed cistern. A variety of flushing systems are available, making it possible to find the right product for almost any application. To make it easier to match up the Geberit buttons with the appropriate cisterns, they are each given a “family name” that they share with the cisterns: Sigma, Omega or Kappa.
