Is PEVA good or bad?

Polyethylene vinyl acetate is considered to be a safe material for shower curtains. Because it is made without chloride, it has no off-gassing like PVC shower curtains do. PEVA shower curtains are waterproof and affordable and I wouldn't hesitate to use them at my own home at all.

Why is PEVA bad?

PEVA is the most waterproof, however, it is not the safest material. It is safer than PVC but still can be harmful. If you want to avoid PEVA, polyester will be the best choice for a liner. Polyester is more water resistant than nylon so it dries quicker when it's wet.
