I think the Niagra just became my favorite model. Here is a link to someone who did a hard walled bathroom. I used to want to do mine, so I saved the directions, url, and all the pics (in case they disappeared.) Now I have decided to just stay with a curtain. The way I have it Velcro'ed, with the wall on one side and fridge on the other makes it very private. Still keeping the hard wall info just in case.
