The Geberit Sigma8 Duofix concealed cistern is contemporary, innovative and space saving. Often referred to as an in-wall cistern, it is designed as a bracketed system so you have the ability to hang your toilet pan off the wall instead of sitting it on the floor.

There are so many advantages to having Geberit in your bathroom but none more so than their reliability. Geberit concealed cisterns are designed in Switzerland and made in Germany. They come standard with a 15-year warranty and have 25 years spare part availability. They are so reliable that when testing toilets for Australian standard compliance the testing facilities will use Geberit cisterns.

Another key feature of the concealed cistern is that it is invisible. It hides inside your wall. The only give away to it being there is the flush plate which is attached to it. Of course, your toilet will be flushing also.

From The Design Team

The concealed cistern is the one thing we would put in every bathroom. Aside from the reliability, it saves so much space by only having a toilet pan and a flush plate visible. It is often a real struggle to create more space in a bathroom. Bathrooms are becoming smaller and smaller so having the ability to manufacture both a physical and visual space saver is a key to creating a comfortable bathroom.

The Geberit Sigma8 Duofix allows you to customize which flush plate and toilet pan you can pair with it. This allows you the greatest of flexibility in matching these products to your decor and provides the perfect solution to creating a fresh, stylish solution to the area of the bathroom we often want to hide.
