Geberit concealed tanks

Tried and true, but ultra-modern
Geberit concealed systems have been installed millions of times around the world for more than 40 years. You can count on their reliability: we perform a leak test on every tank before it leaves our factory. And because we guarantee the availability of spare parts for 25 years, you and your plumber can keep the system operating smoothly for the long term. With dual-flush and stop-and-go flush functions, we've put water conservation right at your fingertips.

Suitable for any situation

Choose the system that fits

Whether it be room height or pre-wall, 2x4 or 2x6, new construction or renovation, Geberit makes an in-wall system that's just right for any situation.


Quality behind the wall

Durable materials

Geberit concealed tanks are made of durable polyethylene (PE). They are blow-molded process from a single, seamless piece of material. After the flush bend is welded on, each tank is leak-tested for one-hundred-percent tightness. More than 60 million installations worldwide and 50 years of experience speak for themselves.


It's about design

Set the stage

With concealed technology from Geberit, everything that belongs behind the wall goes behind the wall. Only the flush plate remains visible – and it's available in a variety of styles and finishes. We believe nothing should get in the way of great design.


Maximum stability

Installation systems

No wobbling, no vibration: Geberit installation systems for wall-hung toilets can bear loads of up to 880 lbs (440 kg). The toilet connects directly to the steel frame of the installation system, which is anchored securely to the wall and the floor.


Easy cleaning

Wall-hung toilet

Geberit systems enable the installation of a wall-hung toilet. Hiding the toilet tank inside the wall and lifting the toilet off the floor opens up the entire floor for cleaning with a damp mop. No more getting on hands and knees to clean hard-to-reach places.


Built to last

Invented by Geberit

Geberit lasts and lasts and lasts – and has been doing so for 50 years. More than 60 million installed Geberit in-wall systems are the best proof. Worried about maintenance? Don't be: Geberit provides spare parts for all functioning components for at least 25 years. In fact, spare parts are currently available for systems that were shipped 35 years ago.


Simple maintenance

Quick and easy

Geberit thinks through all the details. Simple maintenance of the fill and flush valves can be accomplished through the flush plate, without the use of tools.


Forward-looking innovation

The toilet of tomorrow

Geberit systems are always ahead of their time, because Geberit is already thinking today about the toilet of tomorrow. The system comes with built-in connections for additional functions like a bidet seat or touchless flush actuation.
