🔩 R&T, Geberit Sigma 8 & Alpha 12 Concealed Cisterns
The Vex Tornado wall faced floor pan can be paired with one of three concealed inwall cistern options: the R&T G30032, the Geberit Sigma 8 or the Geberit Alpha 12. All three are dual flush cisterns hidden inside the wall cavity, with only the flush plate or button visible once installed. R&T G30032 and Sigma 8 are both slim options built for standard 90mm stud wall cavities, while Alpha 12 is the 120mm option more commonly used for under-counter or low-level installations. Exact flush volumes and product codes can vary by version, so always confirm the specific model before ordering.
