I received this Alvin 59 in. W x 56 in. H Sliding Framed Tub Door in Matte Black Finish and it took all of two hours to install. I am a handy guy and this door was no problem at all. 
The design is beautiful and the black added a modern and elegant look to my bathroom. 
 Look no further than Niveal's Alvin collection of framed alcove tub door. The glass is clear tempered with an easy glide hidden wheel roller system. It also has aluminum matte black hardware which adds to the modern look. Both doors slide so is easy to get in and out.  Love these new doors!
