Our basic liner is water-repellent, odorless, mold/mildew resistant, and even has magnets at the bottom hem to provide weight and stability to keep the liner in place.
The thickness of this liner truly is lightweight - probably the thinnest they could possibly make this material. I'm using it on the side of the tub against the wall where it will not be moved to enter/exit, so we'll see how it holds up. The description of the liner says it has metal grommets, but the photo and the liner I was sent do not. This is unfortunate because the material is so thin it really needs the added reinforcement. However, the description also says the wrong curtain size... It's disappointing that the company was so lazy it just copy/pasted another product's stats, thus misleading a customer.
