GROHE Rapid SL 2-in-1 Set for WC (1.13 m installation height, product code 3853620A) is a complete concealed installation system designed for wall-hung toilets, combining a robust steel frame with an integrated cistern for a clean, modern bathroom finish.
Engineered for strength and reliability, the self-supporting powder-coated steel frame is built to withstand high loads and can be installed against a solid wall or within a stud wall. It comes as a 2-in-1 set, meaning the essential mounting elements are included together, helping to simplify installation for professionals and installers.
The system features a GD 2 dual-flush cistern (6–9 litres), allowing efficient water usage while maintaining strong, consistent flushing performance. It also includes a WRAS-approved filling valve and GROHE’s precision-engineered internal components for dependable operation.
Designed with practicality in mind, the Rapid SL system includes wall brackets and key installation elements, and is compatible with GROHE flush plates (revision shaft may need to be ordered separately depending on the chosen plate). Optional accessories allow further customisation for different installation needs.
Overall, this system is built for durability, easy installation, and long-term performance, making it a popular choice for modern bathroom projects where a concealed, space-saving toilet solution is required.
