I needed a shower door for a very tricky shower under the stairs.  It would've even been difficult to hang a simple shower curtain in this case.  I was sure I'd have the $$$ of a custom glass door until I found the Aqua Fold.  It's amazing!!!  Works great and looks good too.  
When I was shopping for this door, I wasn't sure it would actually maneuver the way I needed it to because I couldn't find any photos.  So I've included photos showing the door folded in or out.  Great product!  Thank you Dreamline!
