The Alvin tub door is a perfect solution to a drab standard curtain install. The stately black anodized frame seems to be quite durable and I expect to get many years of scuff free service.  The opening and closing is near silent and suggests a superb fit and finish.  Installing the door was a snap even for a beginnger, the rail system is straightforward and intuitive.  I would recommend this door setup to anyone doing a bathroom remodel or even someone who wants to convert an otherwise dull space into a more stylish one.
