Having small kids and 3 full baths in our house I decided to buy these for the kids bathrooms thinking that they were PVC to protect the polyester printed ones that they have. I should have read the description before ordering. However, I still installed the extra rod and hung this ones to at least avoid the more expensive printed ones getting too wet (they are also polyester). So far I am happy with the results, but it must be noted that polyester curtains are never 100 percent waterproof. Besides, when installing double curtains, white ones like these tend to look much better together with the colorful printed ones.
