Moen 100663 Escutcheon Chateau Posi-temp Tub Shower

Product Description

The MOEN 100663 is a replacement escutcheon plate designed for Chateau Posi-Temp single-handle tub and shower valve trim systems. The escutcheon mounts against the wall surface, covering the valve opening and providing a finished appearance around the cartridge assembly. This part is finished in Glacier, a clean white color that coordinates with standard white fixture sets. It is typically installed by a licensed plumber or experienced plumbing technician during a trim replacement or bathroom refresh.

This escutcheon is intended for use with MOEN Chateau Posi-Temp single-handle tub and shower configurations. The Posi-Temp valve design maintains consistent water temperature and pressure, and this escutcheon is the wall-facing trim component that completes the installation. It is suited for residential bathroom applications where the existing Chateau Posi-Temp valve body is already in place and only the trim needs to be updated or replaced.

Installation Notes

This component is installed by a licensed plumber or qualified technician. Shut off the water supply to the shower valve before beginning any trim removal or installation work. The escutcheon typically seats flat against the wall tile or surround surface and secures with the appropriate MOEN trim hardware. Do not overtighten mounting hardware, as this can crack the escutcheon body or damage the wall surface finish.
