Concealed Tank

The Geberit Sigma Concealed Tank is an in-wall concealed tank with actuator flush panel or pneumatic push button for a washdown floor-mounted toilet with rear water inlet. It is made for 1.6/0.8 GPF (6/3 LPF) and 1.28/0.8 GPF (4.8/3 LPF) floor-mount, back outlet toilets in 2x6 installations. The tank and fill and flush valves are concealed inside the wall, which makes it an option when a wall-hung toilet is not possible or practical.
