I ordered this curtainas a replacement for my plastic shower curtain because I read that plastic, ie pvc gives off toxic fumes for the life of the product. I am very happy with this polyester curtain, which does not leak and dries really quickly. It is non-toxic, odorless, free of PVC chlorine, which is just what I was looking for. It was easy to install and I have a decorative curtain over it, but you would not have to. It would work fine as the only curtain. It is easily laundered in the washer and comes out beautifully. So glad I got this.
