Grohe RainShower 15″ long shower arm is a high quality and long extension arm that holds the shower head and connects it to the wall. It is a pipe that extends out of the wall to provide more flexibility for shower head movement and adjustment. Grohe RainShower long shower arm is fixed on the wall with an standard height so it is not adjustable. The connecting pipe therefore functions as an essential piece that allows water flow and pressure from the water line behind the wall, straight to the shower head. It is the decorative and functional part of the shower set that creates modern and minimalistic shower and bathroom look.

Shower arm is an important component of a rough-in shower system. Grohe shower arms are made with high quality and durable materials to last for a long time to come. With an uncluttered, modern and simple design, it brings a fresh and minimalistic look to any bathroom set-up or arrangements. They also come with a chrome escutcheon to cover the gap around the mounting.
