For a number of years, we have been using an adjustable shower extension to allow the shower head to be moved up and down easily, since Linda and I are of different heights. But they break easily -- the bolts that allow the extension to be adjusted just do not hold up. So after this most recent failure, we replaced the shower head mechanism completely.
The new scheme has a hand held shower head on a hose. In our case, a WaterPik Model #SRXPP-763M from Lowe's. It has a hand shower with a 6-foot metal hose that can sit on an adjustable height holder on a metal bar. The bar is held to the shower tiles with pieces of 2-sided tape.
The hose attaches to a shower diverter that allows either the hand-held head or the normal fixed head to be used.
There is also a slot in the diverter to hold a hand-held shower, but the WaterPik hand-held shower head is too big and will not fit in the slot in the diverter.
This arrangement is meant to be a temporary solution until we remodel the bathroom completely. We will try to learn from it what works and what does not.
