Geberit concealed cisterns are the classics of modern bathroom installations and have been installed a million times over around the world for more than 50 years. They are known for their proverbial reliability. Every cistern is leak-tested before it is delivered. The 25-year guaranteed spare parts availability provides long-term security. The flush volume of the Geberit concealed cistern can be limited to 4.5 litres. It’s therefore exemplary in terms of water consumption.
