Geberit Duofix Carrier Frame for 2×4 Construction

The Geberit Duofix Carrier Frame (model 111.597.00.1) provides a sleek, concealed solution for mounting a 1.28/0.8 GPF WH CONC toilet tank within standard 2×4 wall construction. By hiding the tank inside the wall cavity, the system frees up valuable bathroom space while maintaining full functionality, allowing the toilet to operate just like a traditional floor‑mounted unit.

Designed with a fully insulated tank, the Duofix frame eliminates condensation, protecting both the surrounding structure and the user from moisture‑related issues. Integrated dual‑flush technology offers water‑saving performance without compromising flushing power, and the frame includes an adjustable mounting bracket that lets you set the toilet seat height anywhere between 15″ and 19″ to suit individual comfort preferences.
