Geberit Flush Valve Baskets
Geberit flush valve baskets, the cylindrical cage that sits inside the cistern and houses the flush valve assembly. Replace the basket when the rubber seal beneath has perished or the cage itself is damaged. For the whole valve assembly see our Geberit flush valves, or for other internal components see Geberit flush valve spares.

Replacement Baskets for Geberit Flush Valves
Geberit Flush Valve Baskets Stocked with and without the Rubber Seal
The basket is the cylindrical plastic cage that sits inside the cistern and holds the flush valve in position. Baskets are stocked two ways: as the cage on its own for installations where the rubber seal underneath is still sound, and as a basket with seal supplied where both have failed together. The seal beneath the cage is a separate rubber component, and a perished seal is what brings the basket to the point of needing replacement.
Plastic colour varies across the range (white, navy, beige) and follows the original Geberit specification for that valve. The colour is cosmetic, sitting inside a closed cistern, but using the correct basket for the corresponding valve is what matters for fitment.
Geberit Baskets Matched to the Valve, Not Universal
A Geberit basket is matched to the valve assembly it houses. The 8cm Basket fits a different valve range from the Concealed Cistern Basket, and the part code on the basket itself is the safest reference when ordering. Where the existing basket is cracked or the seal beneath has perished, replacing both basket and seal at the same time is usually a one-job repair rather than a two-stage one.
Frequently Asked Questions About Geberit Flush Valve Baskets
How do I know if I need a new basket or a new flush valve?
If water keeps trickling into the pan after flushing and the valve itself looks intact, the rubber seal under the basket has usually perished. That is a basket and seal replacement. If the valve body is cracked, the flush rod is bent, or the mechanism fails to seat at all, the whole valve assembly needs replacing rather than the basket. A quick visual check inside the cistern with the water turned off shows which job it is.
Does the basket come with the rubber seal supplied?
It depends on the specific product. Some Geberit baskets ship as the cage alone, intended as a replacement where the existing seal is still sound. Others ship as a basket with seal where both components are supplied together. The product listing on each page states clearly which version is included. Where only the cage is supplied, the matching seal can be ordered separately from the Geberit flush valve spares page.
Are Geberit baskets specific to the Type of valve I have?
Yes. The basket sizes match specific Geberit valve assemblies, and an 8cm basket will not fit a valve designed for a concealed cistern basket. The part code printed on the existing basket is the most reliable cross-reference. Where the basket is too damaged to read, the Type number on the flush valve body itself indicates which basket family the valve belongs to.
