🔩 R&T, Geberit Sigma 8 & Alpha 12 Concealed Cisterns
The Elvera KDK107R 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. The R&T G30032 Frameless In-Wall Cistern is designed for wall-faced floor-standing toilet pans. It features a durable one-piece HDPE tank, fits 90mm stud walls and offers efficient dual flush performance with a WELS 4-star rating. The Geberit Sigma 8 is a slim 80mm option for standard stud wall cavities, while the 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.
