Follow up: Tile contractor met with me and assured me he wanted me happy. He brought in his own carpenter and they devised a cathedral style ceiling that was vast improvement to what had been suggested. This not only enhanced the design, it afforded the function of minimizing the drip. We have yet to test it as unfortunately the tile guy is not running the entire project. Here is a picture to give an idea, still in progress obviously, but beautiful work, can't say enough good things about them and the experience.
