That "new shower curtain smell" is not a harmless chemical odor. It is the smell of volatile organic compounds off-gassing from polyvinyl chloride — PVC — the same material used in industrial pipes and flooring. When you hang a new vinyl shower curtain in a small, poorly ventilated bathroom and run hot water, you are creating ideal conditions for chemical exposure: heat accelerates off-gassing, steam carries airborne compounds deeper into your lungs, and the enclosed space concentrates them.
PVC shower curtains contain phthalates (used as plasticizers to keep the vinyl flexible), organotins (heat stabilizers), and chlorine-based compounds. When heated by shower steam, these chemicals volatilize into the air. The exposure is not a one-time event — off-gassing continues for weeks or months, and the curtain sheds microplastic particles throughout its entire lifespan as it degrades from moisture and heat cycling.
The good news: natural fabric shower curtains work just as well, last longer, and expose your household to zero synthetic chemicals. Organic cotton, linen, and hemp curtains are water-resistant, machine washable, naturally mildew-resistant when properly ventilated, and fully biodegradable at end of life. We evaluated the market to identify the five best options across materials and price points.
Why Vinyl Shower Curtains Are Toxic
PVC is the most toxic plastic in common household use. Its production requires chlorine gas, and its disposal in landfills or incinerators releases dioxins — among the most persistent and dangerous environmental pollutants known. But the health risk starts long before disposal. In your bathroom, a PVC shower curtain is a daily source of chemical exposure.
The specific chemicals are well-documented. Phthalates — particularly DEHP and DINP — are added to PVC to make it soft and flexible. These compounds are endocrine disruptors that leach out of the material over time, especially when exposed to heat and moisture. Organotins, used as stabilizers during PVC manufacturing, are immunotoxic and have been linked to hormonal disruption. And the chlorine compounds in PVC can form chloroform gas in the presence of hot water — a concern unique to bathroom environments.
Then there is the microplastic issue. As PVC and PEVA curtains age, they crack, flake, and shed plastic particles. These particles become airborne in bathroom steam, settle on surfaces, and enter the water supply. Unlike fabric curtains that biodegrade naturally, plastic curtain particles persist in the environment for hundreds of years.
"The 'new shower curtain smell' is not harmless — it is the off-gassing of volatile organic compounds from PVC, including chemicals linked to respiratory damage, liver toxicity, and central nervous system effects."
PEVA (polyethylene vinyl acetate) is often marketed as the "safe" alternative to PVC. While PEVA does not contain chlorine and produces fewer VOCs than PVC, it is still a petroleum-derived plastic. PEVA curtains still off-gas, still shed microplastics, and still end up in landfills. Choosing PEVA over PVC is harm reduction — but it is not a solution. The solution is to move away from plastic shower curtains entirely.
What We Screened For
At Plasticproof, we evaluated shower curtains across five criteria. Every product recommended in this guide had to pass all five.
- Material: 100% organic cotton (GOTS-certified preferred), 100% linen (flax), or 100% hemp. No PVC, no PEVA, no polyester, no nylon. No "fabric-look" plastic curtains.
- Chemical treatment: No water-repellent chemical coatings (PFAS/Teflon), no antimicrobial treatments (triclosan), no wrinkle-resistant finishes (formaldehyde-based). The fabric must rely on its natural properties for water resistance.
- Construction: Reinforced grommets (rust-proof metal or fabric-bound), weighted hem for proper draping, and adequate dimensions (standard 72" x 72" minimum). Quality construction extends lifespan and prevents premature replacement.
- Liner requirement: Strong preference for curtains that function without a plastic liner. If a liner is recommended, the curtain must work with a fabric liner alternative.
- Transparency: The brand must disclose material composition, certifications, and manufacturing origin. Vague claims like "eco-friendly" or "natural materials" without specifics were treated as red flags.

What to Avoid
The following shower curtain types and materials should be avoided if chemical exposure, microplastic shedding, and indoor air quality are priorities for your household.
Avoid PVC / vinyl shower curtains
PVC is the most chemically intensive plastic in common household use. Vinyl shower curtains off-gas phthalates, organotins, toluene, ethylbenzene, and dozens of other VOCs — especially when new and when exposed to heat and steam. The "new shower curtain smell" is literally the smell of toxic fumes. PVC curtains also shed microplastic particles throughout their lifespan and release dioxins when incinerated. There is no safe way to use a PVC shower curtain.
Avoid PEVA shower curtains
PEVA is heavily marketed as the "non-toxic" alternative to PVC, and it is less toxic — but that is a low bar. PEVA is still a petroleum-derived plastic. It still off-gasses VOCs (though fewer than PVC), still sheds microplastics, and still ends up in landfills where it persists for centuries. PEVA also degrades faster than PVC, meaning it needs to be replaced more frequently — generating more waste. Choosing PEVA over PVC is an improvement, but choosing fabric over PEVA is the actual solution.
Avoid Synthetic fabric curtains (100% polyester / nylon)
Polyester and nylon shower curtains avoid the worst PVC chemicals, but they are still plastic — just in fabric form. They shed microfibers (a form of microplastic) into the air and water with every use and wash. Many synthetic fabric curtains are also treated with PFAS-based water-repellent coatings or antimicrobial finishes containing triclosan. If the curtain is marketed as "waterproof" or "water-resistant" but is made from polyester, it almost certainly has a chemical coating. Natural fiber curtains achieve water resistance through weave density, not chemistry.
Avoid "Eco-friendly" curtains without certifications
Terms like "eco-friendly," "natural," "green," and "non-toxic" are not regulated on product labels. Any manufacturer can use them without meeting any standard. Look for specific, verifiable certifications: GOTS (Global Organic Textile Standard) for organic cotton, OEKO-TEX Standard 100 for chemical safety testing, or Certified B Corp status for overall business ethics. If a shower curtain claims to be organic but does not name a certification, be skeptical.
Care & Maintenance Tips
Fabric shower curtains are low-maintenance, but a few simple practices extend their lifespan and prevent mildew:
- Extend the curtain fully after every shower. Bunched-up wet fabric is where mildew starts. Spread the curtain across the full rod so air circulates on both sides and it dries evenly.
- Run the bathroom fan for 15-20 minutes after showering. Adequate ventilation is the single most important factor in preventing mildew on any shower curtain — fabric or plastic. If there is no fan, crack a window or leave the bathroom door open.
- Machine wash monthly in hot water. Use a natural detergent. Hot water kills mildew spores and removes soap residue that can trap moisture. Add half a cup of white vinegar to the rinse cycle for extra antimicrobial action.
- Skip the dryer for hemp and linen. Hang these fabrics to dry — they can shrink in high heat. Organic cotton curtains can typically handle low-heat tumble drying.
- Treat mildew spots with white vinegar or oxygen bleach. Spray affected areas with undiluted white vinegar, let sit for 30 minutes, then wash. For stubborn mildew, soak in oxygen bleach (sodium percarbonate) solution before washing. Avoid chlorine bleach, which degrades natural fibers.
- Use a fabric liner if splash-through is a concern. A cotton or hemp liner is preferable to a plastic liner. Wash the liner on the same schedule as the curtain.

Frequently Asked Questions
Yes. PVC (polyvinyl chloride) shower curtains off-gas volatile organic compounds including toluene, ethylbenzene, and xylene — particularly when new. A 2008 study commissioned by the Center for Health, Environment & Justice found that PVC shower curtains released 108 VOCs, some of which persisted for over 28 days. PVC production and disposal also release dioxins, one of the most toxic classes of chemicals known. The "new shower curtain smell" is literally toxic fumes. Switching to organic cotton, linen, or hemp curtains eliminates this exposure entirely.
PEVA (polyethylene vinyl acetate) is marketed as a safer alternative to PVC because it does not contain chlorine. While PEVA is less toxic than PVC, it is still a plastic polymer. PEVA curtains can release VOCs — though fewer than PVC — and they still shed microplastics over time as they degrade in the humid bathroom environment. PEVA is better than PVC, but it is not a non-toxic solution. For a truly chemical-free shower curtain, choose organic cotton, linen, or hemp fabric instead of any plastic-based material.
It depends on the fabric and weave. Tightly woven organic cotton and hemp shower curtains are naturally water-resistant and do not require a liner — water beads on the surface and the fabric dries between uses. Linen curtains are also water-resistant due to the natural wax coating on flax fibers. Loosely woven or lightweight cotton curtains may benefit from a liner. If you do use a liner, choose a fabric liner (cotton or nylon) rather than a plastic one, or skip the liner entirely and accept that some water may splash through — most fabric curtains handle this well once they swell slightly after the first few uses.
The healthiest shower curtain materials are organic cotton, linen (flax), and hemp. Organic cotton is GOTS-certified, free from pesticides and synthetic finishes, and naturally mildew-resistant when allowed to dry between showers. Linen is inherently antimicrobial and dries faster than cotton. Hemp is the most durable natural fiber option — it resists mold naturally and becomes softer with each wash. All three materials are free from PVC, phthalates, chlorine, and VOCs. They produce zero microplastic shedding and are fully biodegradable at end of life.
A high-quality organic cotton or hemp shower curtain can last 2 to 5 years with proper care — significantly longer than plastic curtains, which degrade and crack within 6 to 12 months. To extend lifespan: wash your fabric curtain monthly in hot water with a natural detergent, ensure it can fully extend and dry between uses, and keep bathroom ventilation adequate to prevent mildew. If mildew does develop, a hot wash with white vinegar or oxygen bleach will remove it. Replace a fabric curtain when it develops persistent mildew that washing cannot remove, or when the fabric thins and becomes transparent.
