I tried to replace my old non-standard Kohler shower head and arm. After I removed the arm, I realized that my shower hose is non-standard as well. I have a male threaded fitting sticking out the bathroom wall Instead of the standard female threaded fitting inside.
I cannot find any shower arm on Amazon that fits it.
Mainly I want to install a handheld shower head.
Any advice on how I can install a new shower arm and head?
