American Standard Square 8-Inch 1.8 gpm/6.8 L/min Water-Saving Rain Showerhead - AMS-1660513

The American Standard square rain showerhead flows 1.8 gpm (6.8 L/min), which is below the 2.5 gpm federal maximum and at the level most water-conservation and green building programs ask for. For property managers and hospitality buyers standardizing on low-flow fixtures across a building, that 1.8 gpm figure is the number to put on the submittal.

It's the showerhead only. A rain-style square head like this needs a shower arm sized for the drop you want, plus an escutcheon flange, and those are ordered separately. On a ceiling-mount install you'll also need a ceiling arm rather than a standard wall arm.

Showerheads in North America, including this American Standard square rain head, use the standard 1/2-inch IPS connection, so it threads onto any conventional wall or ceiling shower arm. Wrap the arm threads with PTFE tape and hand-tighten; no adapter is needed for a standard arm.

It's an 8-inch square face. That's a full rain-style coverage pattern rather than a concentrated spray, so plan the arm position so the face sits over the center of the bathing area rather than flush against the wall.

One finish only: stainless steel, ordered as part number 1660513.075. If you're matching trim across a bathroom group, the stainless face is what you're specifying here, so pair it with a shower arm and valve trim in a compatible finish.

Depends on the arm. A rain head like the 8-inch square American Standard puts a wide, soft drop of water straight down, which works when the head can be positioned over the bather, typically on a longer S-arm or a ceiling drop. If you're swapping one-for-one onto a short, steeply angled existing wall arm, the face will sit too close to the wall and the spray misses. In that case a conventional wall-mount head or a handshower is the simpler retrofit.

Yes. A showerhead doesn't change the valve, so the American Standard square rain head works with any standard pressure-balance or thermostatic shower valve. Keep in mind that at 1.8 gpm the head restricts flow, so in a building with low static pressure the rain pattern will feel softer than a 2.5 gpm head would.
