How to Install a Shower Arm Extension
- Wrap 2–3 turns of Teflon tape on the wall stub-out threads (clockwise).
- Thread the extension arm onto the stub-out — hand tight plus snug with pliers. Wrap a cloth around the arm to avoid scratching the finish.
- Wrap Teflon tape on the extension arm’s outlet threads.
- Thread your shower head onto the extension arm.
- Turn water on and check for leaks at both threaded connections.
FAQ
Will an extension arm affect water pressure?
No. A straight extension arm has no effect on pressure. An adjustable ball-joint arm with a very tight elbow angle may reduce flow very slightly, but it’s not noticeable in practice.
Do I need to turn off my water to install this?
No — all the connections are at the shower head level. No valves or supply lines are involved. The water only comes out when the shower is on.
Bottom Line
Moen’s 6-inch extension arm is solid brass, standard chrome, and works perfectly for most installations. If you need to dial in the exact angle, spend $25 on the High Sierra adjustable version.
