A valve assembly includes an escutcheon that is secured to a valve housing by a threaded adapter. Thus, no screws need extend through the escutcheon, resulting in a more visually pleasing outer appearance. Further, a trim sleeve may be inserted into the escutcheon adapter to turn the escutcheon adapter relative to the valve housing and adjust the position of the escutcheon tightly against the wall. The present invention thus provides an escutcheon which need not have any screws to secure it to the fixed structure, but which is securely held to the valve housing.
