I had wanted a shower head that was adjustable in height (to be used either standing or sitting) and also in angle. The only telephone shower (do they still call them that, or is that totally 70s?) I liked for its height adjustability was not, the saleswoman and I thought, capable of changing its angle. So they were installed, and we moved into the house in December 2008.
This is what they look like. This one is at the bottom of its height adjusting rod.
Last week I was putting it back in its bracket when I heard a crack. I thought "Oh, dear, it's breaking!" But it wasn't broken.
...reveals that the saleswoman and I were quite wrong.
