This ALYVIA SPRING fabric liner is excellent. The quality is great, and the material is much thicker than I expected for a fabric curtain. Unlike cheap plastic liners, this one is soft and lightweight, but it still does a perfect job of keeping the water inside the shower. It doesn't billow out or stick to you while you're showering, which is a big plus. It looks much more elegant than a vinyl liner and is very easy to clean. If you want something that feels high-end but still provides great waterproof protection, this 76-inch long liner is a perfect choice.
