A shower arm is a rainshower fitting for the wall or the ceiling. It can have a round or squared section but it usually has a universal adapter to connect it to whatever kind of rainshower. To install it on the wall, the shower arms have to have lengths variable from 200 to 500 mm for the straight ones and from 120 to 220 mm for the curved ones. The ceiling models don’t have stability problems linked to the size of the rainshower and so the arms can even reach 900 mm. The length range lets you place the rainshower at a 200 – 210 cm height from the shower tray, suiting any ceiling height. You can find a wide choice of shower arms on Archiproducts.
