American Standard Square 8-Inch 1.8 gpm/6.8 L/min Water-Saving Rain Showerhead - AMS-1660788

The 8-inch square rain showerhead flows 1.8 gpm (6.8 L/min) and is both WaterSense and California Energy Commission certified, so it satisfies the California and Colorado-style 1.8 gpm showerhead limits as well as federal WaterSense specs. That combination is what institutional and multi-family buyers need when a project is chasing water-conservation credits or a utility rebate.

Three finishes, each with its own part number: chrome is 1660788.002, polished nickel is 1660788.013, and brushed nickel is 1660788.295. The suffix after the decimal is the finish code, so when you are matching an existing tub/shower trim across a building, order by the full number rather than by the base 1660788.

No. The 1660788 is the showerhead only. A rain head this size wants a long ceiling-drop or an extended wall-mount arm to clear the user's head and center the spray over the bathing area, and that arm plus its escutcheon is a separate order. Plan on it when you are pricing the job.

Yes. It is a standard wall or ceiling showerhead, and showerhead connections in North America are 1/2 inch NPT, so it mates with any conventional shower arm already in the wall. Swapping an old head for this one is a wrench-and-tape job, not a wall opening.

It is built around a drenching rain spray pattern, so the 1.8 gpm is spread across the full 8-inch square face rather than concentrated in a narrow jet. That reads as a soft overhead downpour, not a high-pressure massage spray. If tenants or guests want a forceful, targeted spray or multiple spray functions, a multi-function showerhead is the better call; this one does a single rain pattern only.

Brass construction, which is why it holds a plated finish and tolerates commercial cleaning better than the plastic-bodied rain heads that dominate the value end of the category. For MRO and hospitality work where heads get scrubbed on a schedule, that matters more than the face size.

The face uses easy clean spray nozzles, the rubber-tip type you wipe with a thumb or a cloth to break off scale. In hard-water buildings that lets housekeeping or maintenance clear the face in seconds without pulling the head or soaking it, which is the usual reason rain heads get replaced early.

No. The 1660788 is a fixed overhead rain head with a thin, flat 8-inch square profile meant to hang off an arm, not a hand-held wand. If you need an ADA-friendly hand-held on a bar or hose, specify a separate handshower kit; many buyers run both, the rain head overhead and a hand shower on a diverter.
