I have not yet, in my new house I will and my parents just installed one in their new bathroom recently. I do not have any knowledge about what moisture would do to an LCD tv but as long as the placement is good you should be ok. (As far from shower as possible) Also, many states have codes about placing electronic items above sinks and tubs. Some don't allow it at all and others put restrictions about how far above it has to be. Usually 4 to 6 feet above a tub or sink. In my parents case we were able to mount the TV lower because the outlets and mount for the TV was a couple inches outside the area of the tub. Obviously the swing arm allows for it to be directly over the tub but the laws have not caught up with that yet.
