Shower stall has 1/32 gap at top of enclosure...

My phone booth sized corner shower was caulked by people who obviously get paid by the hour. It hemorrhaged water at every seam and joint and made a huge mess on my bathroom floor and down into my basement. I removed all the old caulking (which took literally two minutes), and recaulked every seam and joint myself. No more leaks.

It occurs to me that if I want to be able to rely on the proper design and construction of an element in my fifth wheel, I had better do (or redo) it myself.
