American Standard 1660186.243 – Frequently Asked Questions
1) Will this American Standard ceiling shower arm thread onto any rain showerhead?
It uses a standard 1/2-inch NPT thread, so it mates with any showerhead cut for 1/2-inch NPT, which is the normal supply thread on residential showerheads. The drop is 6 inches from the ceiling, so pick a head whose face diameter and spray pattern suit that height.
2) Can I use this arm on a wall instead of the ceiling?
No. The 1660186 is a ceiling mount arm, meant to drop straight down out of the ceiling for an overhead rain head. For a wall outlet you need a wall mount shower arm with the standard 1/2-inch NPT connection.
3) What finishes does the American Standard 1660186 ceiling shower arm come in?
Six finishes: Chrome (1660186.002), Polished Nickel (.013), Matte Black (.243), Legacy Bronze (.278), Brushed Nickel (.295), and Brushed Cool Sunrise (.GN0). Order the suffix that matches the rest of the trim in the bath so the arm, head and valve read as one set.
4) Is a 6-inch ceiling shower arm long enough, or should I go longer?
Six inches puts the head close to the ceiling, which works when the ceiling is already at a normal height and you want the rain head tight to the plane. If the ceiling is high, or the shower ceiling is sloped and you need the head lower over the bather, a longer ceiling drop is the better choice. The overall part measures 7.244 by 5.157 by 2.874 inches.
5) What is this shower arm made of, and will it hold up in a rental unit?
Brass body, which is what you want in constant contact with shower water rather than a plastic or thin plated tube. American Standard positions the 1660186 as a residential item, so it suits apartments, condos and single-family baths; for heavy public shower traffic look at a commercial-duty ceiling arm instead.
6) Does the ceiling shower arm come with a flange to cover the ceiling hole?
The 1660186 is supplied as the arm itself with the 1/2-inch NPT thread. It includes no showerhead, so the rain head is a separate order, and the drop pipe must land on a 1/2-inch female fitting roughed into the ceiling.
7) I'm standardizing shower trim across several units. Can I order matching arms in different finishes under one model?
Yes, all six finishes run off the same 1660186 base number, so the geometry and the 1/2-inch NPT connection are identical across them. That lets you spec one arm for every unit and vary only the finish suffix, for example .002 for chrome units and .295 for brushed nickel.
8) How heavy is the American Standard 1660186 arm, and does it need extra ceiling blocking?
The arm weighs 0.728 lb on its own, so the load on the ceiling is mostly the showerhead hanging off it. Standard practice is to block or brace the 1/2-inch drop nipple in the joist bay so the arm and head are not carried by the pipe joint alone.
