Picture of 'Telephone' shower head suction cup mount
If you have persons of very different heights using the same shower, smooth shower walls, and the "telephone" (handheld) style shower head, here's a fairly simple and inexpensive way to create a suction-cup based mount, providing another position to hang the shower head.

Step 1: Materials and Tools

Picture of Materials and Tools
- one suction cup grab bar/handle (can be found for $10 or less in the bath section of most home improvement stores)
- the hanging bracket from a spare telephone shower head (ideally that matches your real shower head)
- a long bolt and nut (I would provide an exact length, but it depends on the model of grab bar/handle)

- a drill and bit to match the diameter of the bolt
- a wrench suitable in size to tighten the bolt/nut
