In-wall toilet frame GEBERIT Duofix Omega H98 for wall-hung toilet (model 111.030.00.1)

GEBERIT Duofix Omega H98 is an in-wall installation frame engineered for mounting a wall-hung toilet. The robust steel carrier frame supports the toilet bowl securely while concealing the cistern and plumbing inside the wall cavity, enabling a minimalist bathroom appearance and efficient use of space. The frame is intended for fixed installation in new builds or renovation projects and includes factory-configured mounting points and water supply and flush mechanism connections.

Advantages

The steel construction delivers high load-bearing capacity and long-term stability for wall-hung toilets. Concealed installation hides the cistern and supply lines behind the wall for a clean, minimalist look and easier bathroom cleaning. Preconfigured mounting points and integrated connections simplify installation and reduce on-site adjustments. The frame’s dimensions and design support common ceramic wall-hung toilet shapes and standard flush mechanisms.

How to use

Position and fix the Duofix Omega H98 frame within the wall cavity or against a finished stud framework following the manufacturer’s mounting heights and clearances.

Verify wall structure and load-bearing capacity before installation, and perform water pressure and leak tests after connections are made. Installation by a qualified plumber or installer is recommended to ensure compliance with local building codes and optimal performance.
