Abstract: A Roman tub installation includes a hub and handle assembly, a valve, a sleeve coupled to the valve's body, a stem adapter coupled to the valve's stem and to the hub and handle assembly, and a threaded collar coupled to the sleeve. The hub and handle assembly includes a hub having a threaded portion for engaging the threaded collar, thereby coupling the hub and handle assembly to the sleeve and valve body, and a handle disposed adjacent the hub. A handle stem extends from the handle and couples the handle to the stem adapter. The stem adapter couples the handle's stem to the valve's stem, thereby coupling the handle to the valve stem.
