Frequently asked questions about Geberit Kombifix

In what situations is Geberit GIS or Geberit Duofix more suitable than Geberit Kombifix?

Geberit GIS offers maximum flexibility for every conceivable constructional situation, whether in solid or drywall construction. This makes it ideal for both bathroom renovations and sanitary facilities in new constructions. Unique bathrooms can be designed and created with free-standing sanitary walls, half-height room dividers, room-height or part-height prewalls, niches and shelf surfaces.
Geberit GIS is also ideal for the prefabrication of sanitary rooms. Prefabricated bathrooms save time on the building site and help to optimise processes.

Geberit Duofix is the ideal solution for drywall construction with statically self-supporting prewall elements, whether as part of the Duofix system or in combination with other drywall construction systems. The installation elements suitable for partition wall installations, in-wall installations in lightweight stud walls, and part-height and room-height prewall installations.

Geberit Kombifix is an installation system that is primarily used in solid construction or wet construction. It is suitable for new constructions, refurbishments and renovations, as it has been specially developed for use in masonry or concrete walls. The direct connection with the building structure ensures excellent structural properties.

What is the advantage of Geberit Kombifix compared to a freely installed concealed cistern without an installation element?

With components like the flush pipe, connection bend and threaded rods already positioned on the Geberit Kombifix element, sanitary professionals can fit appliances much more easily and save valuable time.

A single concealed toilet cistern may be less expensive upfront, but it results in considerably more work on the building site and longer installation times.
