Abstract: A modular shower arm construction for use in removably attaching a shower fixture to an unthreaded end of a pipe extending outwardly from a shower wall without affecting connection of the pipe to a water supply system behind the shower wall includes a tubular shower arm, an adapter and a coupling nut. The adapter is fixed to the pipe, either by a set screw or through the use of a threaded nipple. The tubular shower arm has an outwardly flared end which extends within the coupling nut and the coupling nut is threaded onto the adapter and holds the tubular shower arm to the assembled components. An escutcheon overlies and covers all of the connecting elements and is removed when the tubular shower arm and adapter are removed from the unthreaded end of the pipe.
