I had been wanting to install a window in the bathroom, so when we were at the fall rally I got a window from Kinro's, Montana's supplier. There is a stud almost in the center of the wall and a header for the bedroom slide is attached it it. The window is 12" x 24" which is the same a the kitchen and bedroom windows. I would have liked a larger window, but there is not enough room for one. Next is to put a day/night shade over the window with a valance of some type. The window really lightens up the bathroom and was easy to do, just a little nerve racking to cut the hole.
