I am very curious as to how the problem of having a regular sized window was solved inside this shower. From what I can tell, there are two sets of glass covering the windows so as not to have dry rot and other problems when the water hits the windows. Is what I see correct? Are there hinges so one can open the window while not showering? Any information will be greatly appreciated as this will solve the problem of changing the size of my window to a tiny one. I do not wish to change it bc of added cost and little natural light that I will get by doing this. Much thanks!
