I really, really want a window in the WC room (that's watercloset for you nautical folks). I found a 24X24 flush mount window and was wondering is there is any reason I shouldn't do this. I'm not sure where the aluminum frames are but figured that I can find out.
As long as there aren't any aluminum frame members in the way, I don't see any issues. But if you find a frame member in the way, I would think twice. I don't imagine there would be any wiring in the way? Might be worth checking with FR, as once you start, there's no going back!
