Do not buy. Does not stick to the tile for long
We bought both the shower bar suction device and this shower hose holder arm.  Bar works great.  HOWEVER, this shower arm was not made for the job. Once you suction it and then put a shower hose and head in the grip it pretty quickly it comes off the wall.  My best guess is the suction cup is not large enough in diameter to off set the weight of the shower head or not large enough in diameter.  Just suctioning the device to the wall with nothing in the grip it falls off the wall on its own in a few hours.  It should be noted we don't have an unusually heavy shower head, a standard price fister.
