No, new shower curtains are not toxic, no matter what material the are made of.

There is quite a trend in buying natural cotton and hemp shower curtains lately - and they look great - but there’s no need to buy them for safety reasons.

Not sure where this myth came from but it is a myth.

The PVC and PEVA  (EVA) shower curtain have a slightly chemical smell but that soon wears off in use and that’s about as toxic as you’ll get.

Of course plastic and vinyl fabrics and liners are not green - you can’t easily recycle them - but unfortunately these materials are necessary to make the curtain or liner waterproof.
