The chemical smell that comes off a brand-new plastic shower curtain isn’t your imagination, and it isn’t just a manufacturing scent that airs out overnight. On a PVC (vinyl) liner, it’s volatile organic compounds — plasticizers and other additives used to keep the sheet flexible — leaving the plastic as it off-gasses after you unwrap it. The material fix isn’t complicated once you know what to check: PEVA and EVA liners skip the chlorine chemistry that makes PVC PVC, and fabric liners skip plastic altogether, but each option trades one hazard for a different maintenance habit.

A plastic liner already hanging in the bathroom has done most of its off-gassing — that release is fastest in the first days after unwrapping, which is why the smell fades. Pulling it down to buy a PEVA one trades a sheet that has gone quiet for a new sheet at its loudest, and puts the old one in the trash. Wipe it, spread it flat to dry, and replace it when it splits or won’t come clean.
What causes the “new shower curtain smell”
PVC is rigid on its own; a plasticizer is what makes a vinyl shower curtain soft and flexible instead of brittle. Those additives aren’t chemically bonded to the plastic, so a portion of them leaves the sheet as a gas over time — fastest right after the curtain is unpacked, which is why the smell is strongest in the first days. The lab study most often cited for this is the Center for Health, Environment & Justice’s “Volatile Vinyl: The New Shower Curtain’s Chemical Smell” report, which tested PVC shower curtains for the chemicals they release as they off-gas. That finding, along with similar reporting at the time, is part of why some health and environmental groups have called specifically for restricting DEHP — a common vinyl plasticizer — in shower curtains, the way it’s already restricted in children’s products under federal law.
That last distinction matters: the Consumer Product Safety Improvement Act caps eight specific phthalates, including DEHP, at 0.1% in children’s toys and child care articles. A shower curtain sold for a bathroom, adult or otherwise, isn’t a children’s article under that law, so a PVC liner isn’t required to meet the same phthalate cap a teether or play mat is. “PVC-free” on a curtain’s packaging is addressing exactly this gap — it says the maker skipped the material the off-gassing question is attached to, not that some other, unrelated hazard was tested and cleared.
PEVA and EVA are chlorine-free — they’re still plastic
PEVA (polyethylene vinyl acetate) and EVA (ethylene vinyl acetate) are the material behind most curtains marketed as “non-toxic” plastic liners today, including Target’s Threshold line and the LiBa liner sold on Amazon. Neither uses the chlorine chemistry that makes PVC PVC, so neither carries the same off-gassing route the CHEJ study documented. Quiet Town states its Sun Shower curtains are “chlorine-free, PVC-free, and BPA-free” in those exact terms, which is a specific, checkable claim rather than a vague one.
What that claim doesn’t cover is whether the sheet is plastic at all. PEVA and EVA are still petroleum-derived polymers, and none of the PEVA or EVA product pages checked today published independent test results for VOC emissions or microplastic shedding — the “non-toxic” language on the package is answering the chlorine question specifically, not making a broader plastic-free claim.
The fabric options: polyester, cotton, hemp, and linen
Skipping plastic entirely means a fabric curtain, and the maker pages split into two different products that get marketed the same way. Parachute’s liner is 100% polyester with a water-repellent finish, made to hang alone as a functional liner — it’s machine washable and priced at $29. Bean Products’ hemp curtain and Rawganique’s hemp, cotton, and linen curtains are untreated natural fiber: no water-repellent finish, no plastic sheet, and no claim to being a standalone waterproof liner.
Is polyester a non-toxic shower curtain material?
Polyester itself isn’t vinyl and doesn’t carry PVC’s chlorine-based off-gassing question. The open question is the water-repellent finish. Parachute markets its polyester liner as “completely waterproof and mildew resistant” without naming what makes it repellent or stating a PFAS position either way — and water-repellent textile finishes are one of the more common places PFAS chemistry shows up when a maker doesn’t say otherwise. Until a brand states its finish chemistry directly, treat a water-repellent fabric liner as an open question, not a cleared one.
Do fabric liners need a plastic liner behind them?
It depends on the fabric and the finish. A treated, water-repellent fabric liner like Parachute’s 100% polyester version is designed to hang alone and keep water in the tub. An untreated cotton, hemp, or linen curtain — the kind Bean Products and Rawganique sell — is porous and will let water through unless it’s hung well inside the tub or paired with a liner. None of the natural-fiber makers checked today market their curtain as a standalone waterproof liner.
How do you keep a cotton liner from mildewing?
Cotton, hemp, and linen have no plastic sheet to trap moisture against, but they do absorb water, and a fabric curtain left bunched and wet is exactly what mildew needs. Bean Products tells buyers to wash its curtains “often, like your towels,” and the practical fix is the same one that works for any bath towel: pull the curtain flat after each shower so it dries between uses, and machine wash on a regular schedule rather than waiting for visible spotting.
There’s a third option most comparison lists skip: no liner at all. A curtain that hangs fully inside a tub with a curved rod or shower door doesn’t need a separate liner to keep water contained, which sidesteps the material question by removing the product. That only works with the right tub geometry and rod placement, so it’s a bathroom-specific option rather than a universal one.
Are PEVA shower curtains toxic?
PEVA (polyethylene vinyl acetate) and EVA (ethylene vinyl acetate) are made without the chlorine used to produce PVC, so they don’t off-gas the same chlorine-based volatile compounds a fresh PVC curtain does. That’s the specific claim behind “non-toxic PEVA” marketing, and it holds up — PEVA isn’t vinyl chloride plastic. It’s still a petroleum-derived plastic sheet, though, and none of the PEVA or EVA liners checked today published independent VOC or microplastic-shedding test results on their own product pages.

Where this fits with the rest of the bathroom
A shower curtain liner is one material decision in a bathroom that has several. The same checked-not-assumed approach applies to recycled toilet paper, whether bamboo toilet paper is septic-safe, plastic-free dental floss, and the broader zero waste bathroom setup — each one has its own material-specific trade-off rather than a single universal swap.
The bottom line
If the plastic smell itself is the concern, PEVA or EVA solves that specific problem — both skip the chlorine chemistry the CHEJ study tied to PVC off-gassing, at a price close to what a PVC liner already costs. If avoiding plastic altogether matters more, a fabric liner is the only category that does it, and the choice inside that category is really a laundry decision: a treated polyester liner like Parachute’s works alone but leaves its finish chemistry unstated, while an untreated hemp, cotton, or linen curtain from Bean Products or Rawganique skips the finish question and asks for a regular wash schedule instead. No single row in the table above clears every column — check which trade-off the bathroom can actually live with before buying.
The one you buy once, and where the sheet ends up
Only the fabric rows come with a maker’s instruction to wash rather than replace: Bean Products says to wash its hemp curtain “often, like your towels,” and Parachute’s polyester liner is listed machine washable. None of the three PEVA listings states machine washability at all, which is what an $8 liner is priced around. End of life follows: a split PEVA sheet and the film it was folded into are landfill, since EPA’s common-curbside list stops at bottles, jars, cans, and cardboard. A hemp curtain washes, then becomes rags.
The same fragrance-disclosure and off-gassing questions apply to air fresheners — see our non-toxic air freshener guide for what typically gets disclosed there.
