Ideal Standard Boost Volume Control Handle — A963851AA
The Ideal Standard A963851AA is an authentic manufacturer replacement volume control handle finished in premium polished chrome. Engineered specifically for the Trevi Boost built-in shower valve collection (notably model A5300AA), this handle operates the flow/on-off cartridge. Replacing a worn, limescaled, or cracked handle restores precise, smooth water volume regulation and returns the front trim of your shower to a clean, factory-standard appearance.

Installation Note
Designed specifically for the volume/flow control side on Trevi Boost built-in shower valves (including A5300AA). This is the dedicated on/off volume handle, not the thermostatic temperature handle.
Fitting Tip: Isolate the shower supply before maintenance. Remove the end indice or cover cap to expose the retaining screw, unthread the existing handle from the valve spline, and slide the new A963851AA into position before securing.
