Premium feel and truly waterproof!
Color: White, Size: 72"W x 76"L (Pack of 1)
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.

Love the new shower curtain. It is soft and easy to wash once it does get dirty. Repels the water and keeps our floor dry.

Great washable shower curtain liner
Color: White, Size: 72"W x 72"L (Pack of 1)
I didn’t expect to have strong opinions about a shower curtain liner—but this one earned it. The ALYVIA SPRING liner feels noticeably higher quality than the typical thin plastic ones. The fabric is soft but still completely waterproof, so it keeps water where it’s supposed to be without that stiff, crinkly feel. The 3 magnets at the bottom are a game changer—they help keep the liner in place and prevent it from clinging to you mid-shower (which is always the worst). It hangs nicely, dries quickly, and doesn’t get that gross mildew smell after a few uses. Installation was simple, and it works great with a standard curtain setup. If you’re tired of replacing cheap liners all the time, this is a solid upgrade that actually lasts. Highly recommend!
