Claire Whitmore If you have ever unwrapped a new shower curtain and been hit by a strong plastic smell, you already understand why so many people are searching for the best non toxic shower curtains. That chemical odor comes from compounds that can off-gas into your bathroom, and for anyone concerned about indoor air quality, health, or the environment, a safer curtain is a worthwhile upgrade. The good news is that non-toxic options have come a long way and now offer the same waterproofing and style as conventional curtains without the harsh chemicals.
In this guide, we explain what makes a shower curtain non-toxic, which materials to look for, and how to choose the best non toxic shower curtains for your bathroom. Rather than reviewing individual products, we focus on the materials, certifications, and features that matter so you can shop with confidence and peace of mind.
What Makes a Shower Curtain Non-Toxic?
The main concern with conventional shower curtains is PVC, a plastic that can contain phthalates and other additives. Cheap PVC vinyl curtains are the ones most likely to produce that strong “new shower curtain” smell, which is caused by volatile organic compounds off-gassing into the air. A non-toxic shower curtain avoids these problem materials, using safer plastics or natural fibers instead. The result is a curtain that is odor-free, healthier for your home’s air, and often more environmentally friendly.
Safer Materials to Look For
PEVA
PEVA is a chlorine-free alternative to PVC that is free of the phthalates commonly found in vinyl. It offers the same waterproofing and affordability as traditional plastic curtains without the harsh chemical smell. PEVA is the most popular non-toxic choice, and options like the Barossa Design PEVA Liner and the LiBa PEVA Curtain are BPA and PVC free with no chemical odor.
EVA
EVA is another chlorine-free plastic that is soft, flexible, and free of the additives found in vinyl. It tends to be a bit more durable and softer to the touch than standard PEVA. A curtain like the AmazerBath EVA Curtain offers an ultra-soft, waterproof feel without the toxic concerns.
Recycled PEVA
For an even greener option, recycled PEVA curtains reduce plastic waste while keeping the non-toxic benefits. A sustainable choice like the Bowery Home Recycled PEVA liner combines eco-friendly materials with a frosted, odorless finish.
Natural Fabrics
For the most natural approach, fabric curtains made from cotton or other natural fibers avoid plastic entirely. A natural fiber option like the Natural Cotton Fabric Liner is earth-friendly, breathable, and machine washable, though fabric usually needs a separate liner or treatment to stay fully waterproof.
TPU-Coated Fabric
TPU is a newer, high-quality material that is both non-toxic and highly durable. TPU-coated fabric curtains feel like premium hotel textiles while remaining waterproof and odor-free. A hotel-quality option like the TPU-Coated Fabric Liner is a great pick if you want a plush, upscale feel without any chemical smell.
Key Factors to Consider Before Buying
Certifications and Labels
Look for clear labeling such as “PVC-free,” “BPA-free,” “phthalate-free,” “chlorine-free,” or “non-toxic.” These indicate the curtain avoids the most concerning chemicals. Reputable brands are transparent about their materials, so if a product does not disclose what it is made of, treat that as a red flag.
Waterproofing
A non-toxic curtain still needs to do its main job: keeping water in the shower. PEVA, EVA, and TPU are all naturally waterproof, while natural fabrics may need a separate waterproof liner. Many non-toxic liners include weighted magnets or stones at the bottom, like the SUSTAINAURA PEVA Liner, which stay put and help prevent water from escaping.
Size and Fit
Standard shower curtains measure about 72 by 72 inches, but tubs, stalls, and stall showers vary. Measure your space before buying, and check whether you need a longer or wider curtain. Most liners include reinforced, rust-proof metal grommets, which resist tearing and corrosion over time.
Ease of Cleaning
Bathrooms are humid, so mildew resistance and washability matter. Many PEVA and EVA liners can be wiped down or machine washed, and a clear or frosted design makes it easy to spot buildup so you can clean before mold sets in.
Liner vs. Curtain: What You Need
It helps to understand the difference between a liner and a decorative curtain:
- Liner: The waterproof inner layer that faces the shower and keeps water contained. This is where non-toxic materials matter most, since it gets wet and warm.
- Decorative curtain: The outer layer, often fabric, chosen for style. It stays drier and is more about looks.
Many people pair a non-toxic waterproof liner with a fabric outer curtain for the best of both worlds. If you love the look and feel of textile curtains, our guide to the best fabric shower curtains pairs perfectly with a non-toxic liner.
Balancing Health, Style, and Budget
Non-toxic does not mean expensive or plain. PEVA and EVA liners are budget-friendly and come in clear, frosted, and colored finishes, while TPU and fabric options offer a more luxurious feel. For an inexpensive, health-conscious starting point, a simple PEVA liner works beautifully.

Why the Chemical Smell Matters
That distinctive “new shower curtain” odor is more than just unpleasant; it is a signal that the curtain is releasing volatile organic compounds into your bathroom air. Because bathrooms are small, often poorly ventilated, and frequently warm and humid, those compounds can linger and concentrate more than they would in a larger room. For households with children, people who are sensitive to chemicals, or anyone who simply wants cleaner indoor air, avoiding that off-gassing is a meaningful benefit. Non-toxic curtains made from PEVA, EVA, TPU, or natural fibers do not produce that smell, so your bathroom stays fresher from the very first use.
It is worth noting that even a low-odor curtain can carry a faint plastic scent when first unwrapped, simply from being packaged. This usually fades within a day or two of airing out and is not the same as the persistent chemical smell of PVC vinyl. If a curtain’s odor does not fade after airing, that is a sign it may not be as low-emission as advertised.
Style Without Compromise
A common misconception is that going non-toxic means settling for a plain, utilitarian look. In reality, safer materials come in a wide range of finishes, from crystal clear and frosted to solid colors and textured weaves. Clear and frosted liners keep a shower feeling open and bright, while colored or fabric options let you coordinate with your bathroom decor. This means you can protect your indoor air quality and still create a bathroom that looks polished and intentional.
Care and Maintenance Basics
- Air it out: Even non-toxic curtains benefit from unfolding and airing before first use.
- Keep it dry: Spread the curtain out after showering so it dries fully and resists mildew.
- Clean regularly: Wipe down PEVA and EVA liners, or machine wash washable options, to prevent soap scum and mold.
- Ventilate the bathroom: Use a fan or open a window to reduce humidity, which extends the life of any curtain.

Frequently Asked Questions
What material is best for a non-toxic shower curtain?
PEVA and EVA are popular, affordable, chlorine-free plastics that avoid the phthalates found in PVC. For a more premium feel, TPU-coated fabric is both durable and non-toxic, while natural cotton is the most eco-friendly option.
Why do some shower curtains smell like chemicals?
That smell usually comes from PVC vinyl curtains off-gassing volatile organic compounds. Choosing a PVC-free curtain made from PEVA, EVA, TPU, or natural fiber eliminates the odor.
Are PEVA shower curtains really non-toxic?
PEVA is free of chlorine and the phthalates found in PVC, making it a much safer choice than traditional vinyl. Look for liners clearly labeled PVC-free and BPA-free for added assurance.
Do non-toxic shower curtains still keep water in?
Yes. PEVA, EVA, and TPU are fully waterproof, and many liners include weighted magnets or stones to keep the bottom in place. Natural fabric curtains may need a separate waterproof liner.
How do I keep a non-toxic curtain free of mold?
Let the curtain dry fully after each use, ventilate the bathroom, and clean it regularly. Wipe-clean PEVA and EVA liners and machine-washable options make mildew easy to manage, and replacing an inexpensive liner every so often keeps your shower fresh.
