Shower Arms

Shower arms and flanges in lengths from 6" through 20", straight, S-shaped and ceiling-mount, in chrome, brushed nickel, matte black, oil-rubbed bronze and polished nickel.

The arm sets the showerhead's height and how far it reaches into the enclosure, and it is the cheapest way to fix a head that sits too low or sprays the wall. A standard arm is around 6"; longer arms and S-shaped arms move the head outward and upward without touching the plumbing in the wall.

A rain head has to come from the ceiling or from a long right-angle arm, because it sprays straight down — mounted on a standard arm it soaks the wall instead of the user.

The thread is 1/2" NPT and effectively universal, so an arm from one brand fits another brand's head. Finish is the real matching problem: manufacturer chrome varies subtly, and Grohe Chrome and a generic polished chrome will not read as identical side by side.

Brands include Moen, Gerber, Grohe and Hansgrohe.

Frequently asked questions

What length shower arm do I need?

A standard straight shower arm is about 6". A 10" to 12" arm moves the head farther into the shower, and a ceiling-mount arm drops the head straight down for a rain showerhead.

Will any shower arm fit my showerhead?

Almost always. Shower arms and showerheads use 1/2" NPT threads, so the arm brand does not have to match the head. Match the finish so the arm and head look the same.

How do I replace a shower arm?

Unscrew the old arm counterclockwise from the wall fitting, wrap the new arm's wall threads with thread seal tape, thread it in by hand and snug it so the head points the right way. Slide the flange against the wall last.
