I have tried several different (and expensive!) shower heads, but none of them gave me the spread pattern and coverage I wanted. Doing some other projects with PVC pipe, I hit upon this idea.
Step 1: Parts
1/2 inch PVC pipe (12 to 24 inches)
1/2 inch PVC end cap
1/2 inch PVC end connection
Shower hose (standard 1/2 inch connection)
1/8 inch drill bit
3M Command hooks and adhesive strips
