Thanks - I tried using a window and couldn't figure out how to cover up the view to outside so I will try that. My window also has a sill on it which I can't get to go away either. Is there a difference between a window opening and window?
I am trying to put a niche in my shower and am having no luck figuring out how to do it. None of the training videos or tips on YouTube have showers with them either. Any suggestions?
