You have a loose shower head but don't want to rip open the tile to re-secure it. What should you use to make it stop wobbling?
Answer Foam
While you're free to try any of the other methods, they would not work very well--not to mention, zip ties and duct tape would look bad. For a seamless finish and a sturdy shower head, use expanding foam. Expanding foam encases the pipe within the wall and locks it into place.
