Geberit DuoFix concealed toilet tank system is a desirable alternative to conventional floor-mounted toilet systems. In-wall toilet tanks conceal behind the wall for a more sleek and modern look. With its slim profile, Geberit DuoFix concealed toilet tank system saves up to 11 inches of bathroom space while providing a seamless design and a clean bathroom area by exposing only the toilet bowl and flush actuators. In addition, wall-mounted toilets lift off the floor to provide more accessible area underneath the toilet bowl therefore makes cleaning much easier.

Geberit DuoFix represents the next level of innovation of in-wall carriers. It is whisper-quiet, water-conserving with dual flush mechanism and easy to connect without tools. The tank and the carrier mount behind the drywall therefore insulates noise which makes it considerably more silent than standard toilets. Also the actuator panel removes easily to give access to the inner tank components for easy maintenance.

Geberit DuoFix in-wall toilet carrier has cUPC and Watersense standards and also complies with ASME A112.19.2/CSA B45.1.
