Tell us about yourself!
I made one of these last week; if I can do it, chances are a reasonably smart dog can do it. I did find shower heads with 1.25 gpm flow rates. The result is that the shower feels like standing in a summer rain that's just the right temp. I had an old hand held shower, so I used that to make the connection between the water inlet and the shower, eliminating the tubing and hose clamps. It works great!
Sometimes the cloudiness is caused by condensation inside the lights. Good luck.
