Accordion shower door question

Thanks for the link to the roller shower, that is pretty cool and I may look into that. I currently have the accordion door in my PC Cruiser and hate it. I was looking at the Extend-a-shower rod to replace it but that roller shower may be better.

I think with a 36" door in a 25" track you are going to have an issue with the folds not flattening out enough. Which, depending on the installation, could allow water to drain outside the tub. Just something to think about.
