How to replace a shower head without actually replacing it?
Do what I do: Pivot the shower head off to one side, so it sprays against the wall, as you shave your legs on the far side of the shower. (If you have the normal kind like that photo shows, it should easily be capable of this.) After pivoting the shower head, you can still reach into the spray to wash off the razor, but it won’t spray on your legs and wash off the shave gel or foam before you want it to. Then you can turn the head back to the center of the shower when you wish to wash off. Cost: $0.
