Yup, that's what weekends are for!
I just spent $500 on a emergency plumbing call. The cylinder in my tub spout/handle gave out rather suddenly, and the only way to turn the water off was to turn off the entire house. Fortunately, when I called, I was quoted overtime, rather than doubletime for it being a Sunday, and they did honor quote.
Added having an access panel cut in the closet that backs up to the shower and a shutoff valve to my list of home to-do's.
