I recommend a dry run to test it out. "Dry" run since you will be testing with water, but you yourself will not be in the water. Turn on the shower. Make sure there are no drips or sprays or explosions. If everything seems okay, it probably is. This isn't rocket science. Take a shower if you want. Take two. No need to hang your head to get it wet, you can keep your chin up, high and proud, now that you raised your shower head.
