Concealed Tank

The Geberit Sigma Concealed Tank offers many of the benefits of the Geberit in-wall toilet system and replaces a standard toilet when a wall-hung toilet is not possible or practical. All the working parts, including the tank and fill and flush valves, are concealed inside the wall. The 1.28/0.8 GPF version (109.781.00.1) is specified for 1.28/0.8 GPF (4.8/3 LPF) floor-mount, back outlet toilets in 2x4 installations.
