After seeing this type of shower door on a European trip, I knew I wanted it for my new remodel. The benefit of a bi-folding door allows full access to the shower valves without having to reach around a fixed panel and getting wet! I searched many sites and picked the DreamLine Aqua Fold. There certainly was less expensive options but I seriously doubt it would match the quality of DreamLine. The hardware is heavy duty and the installation was a breeze. I am very handy and it took less than an hour to install.. Time will tell,  but I'm very satisfied with my purchase. I mounted this on a 4 1/2' long tub and the coverage is perfect.
