I failed to mention a similar setup in the apartment I lived in... Same deal, a live gas line with a valve and a small nipple on the end, in the shower/tub space.

I turned the valve and it went hiss...

It was at that point that I decided not to take a sawzall blade to any protruding gas lines in the way of my ceiling boxes!

Whoa Nelly!
