Showerhead attachment assembly

Abstract

A shower arm attachment assembly may include a shower pipe coupling member, an arm coupling member, and a locking nut or sleeve. The shower pipe coupling member connects to a shower pipe, and the arm coupling member fluidly connects to a showerhead arm. The arm coupling member may be joined to the shower pipe coupling member. The arm coupling member may be selectively rotatable relative to the shower pipe member. Rotation of the arm coupling member relative to the shower pipe coupling member may be selectively controlled by selectively engaging a locking nut with the coupling members or selectively engaging a keying feature associated with one or both of the coupling members. Rotation of the coupling members relative to each other causes rotation of a showerhead relative to a shower pipe attached to the showerhead using the attachment assembly.
