8 cm thick built-in toilet cistern for floor-standing sanitary fixtures
Grohe 38 863 000








Description
The Grohe toilet cistern for floor-standing sanitary fixtures is an innovative, space-saving solution, ideal for built-in installations in bathrooms with limited depth, thanks to its thickness of just 80 mm.
Designed to maximize efficiency and minimize space, this cistern offers reliable performance and a discreet design. Made of PE (polyethylene) with a vinyl resin coating, the cistern guarantees durability and long-lasting resistance. The water inlet is from the top, and the inlet valve is designed to be low-noise, contributing to a quieter bathroom environment.
The functional heart of this cistern is the AV1 flush valve, which offers remarkable versatility in actuation types for greater water savings. The first is the Dual Flush, which allows you to choose between a full flush (6-9 liters, adjustable) or a reduced flush (3 liters). The second is the Start/Stop, where the user can interrupt the flow of water by pressing the flush button again.
With this toilet cistern it is possible to install the control plates only vertically (not included, to be purchased separately) and the GROHE Fresh system (not included but to be purchased separately), the innovative system for sanitising the hidden WC.
