Grohe 19910000 Eurocube Volume Control Trim

Summary

Grohe 19910000 Eurocube Concealed Stop Valve Trim

The Grohe 19910000 is a Eurocube concealed stop valve trim set, designed to provide external control and a finished appearance for a concealed isolation valve.

Function

The trim allows manual isolation of water supplies while concealing the valve body within the wall.

Installation Notes

Fit to the compatible concealed valve body once wall finishes are complete.

Grohe 19910000 Eurocube is a chrome volume control trim for a separately installed concealed valve. It provides the exposed metal cube handle and square sliding escutcheon with wall sealing. The concealed valve body is not included.

The handle operates the concealed valve to control water flow, while the escutcheon finishes the opening at the wall. This is an external control and trim assembly, not a complete bath tap, thermostatic mixer or internal flow cartridge. It does not provide temperature regulation.

Technical Details

• Projection from the finished wall to the front of the handle: 55-77 mm

The adjustable trim dimension is not a universal concealed-body installation depth. Check the installation requirements for the exact valve body, together with the finished wall position.

Before Ordering and Fitting

Check the trim code, concealed valve model, handle-fixing arrangement and available adjustment against the existing installation. Fit the trim after the wall finish is complete, using the correct spindle extension, sleeve and handle connection. Do not treat this volume control as a substitute for a separate service-isolation valve.

Persistent dripping from the shower head or spout when the control is closed can indicate a fault in the concealed valve headpart or its sealing surfaces. Replacing the decorative trim alone will not repair an internal valve-sealing fault. Isolate the water supply before servicing the concealed valve.

For help identifying the required component, contact us with photographs of the complete control, the exposed fixing arrangement and any available valve or part codes.
