Curious about the most hazardous item in your bathroom? It's your shower curtain.
While mold growth is a major concern, toxicology experts have identified additional risks associated with shower curtains.
Our specialists explain why shower curtains can be harmful, along with easy solutions to minimize mold and health risks tied to this common bathroom accessory.
The Toxicity of Shower Curtains
Why are shower curtains considered toxic? Many items get labeled as 'toxic' these days, but in the case of shower curtains, there's genuine cause for concern.
Dr. Paul Savage, a toxin authority, clarifies, 'Indeed, shower curtains can be toxic, particularly those crafted from PVC.'
The problem with PVC (polyvinyl chloride) curtains, according to Dr. Savage, is that they 'emit volatile organic compounds (VOCs) into the atmosphere, which are associated with respiratory problems and other health issues.'
A study conducted by the Center for Health, Environment & Justice revealed that PVC shower curtains release over 100 potentially harmful VOCs within the first month of use, at levels 16 times higher than the safety thresholds set by the U.S. Green Building Council.
Newer curtains release more VOCs. A distinctive 'new shower curtain' odor indicates you've purchased a PVC curtain, which is a mix of harmful chemicals.
Mold is another concern linked to shower curtains. Dr. Savage notes that mold can be particularly troublesome for those with respiratory issues. It can worsen allergies, asthma, and other breathing difficulties.
Even if mold doesn't trigger sensitivities for you, it can lead to unpleasant body odor. According to Cleveland Clinic, your shower curtain might be responsible for odor problems, even if you shower regularly—definitely not life-threatening, but certainly bothersome.
Mold thrives on shower curtains, regardless of the material. Damp environments are ideal for mold growth, and curtains often soak up water, especially if they're pushed aside after use or are too long for the space.
Four Tips for a Safer Shower
1. Swap Shower Curtains for Glass
Replace your hazardous shower curtain with glass.
Plastic shower curtain liners are popular due to their affordability and ease of cleaning. The problematic PVC curtains are usually the thin, transparent liners meant to protect your more expensive fabric curtains.
Many of us replace these liners frequently, which means we're regularly inhaling those new VOCs.
The most effective solution? Ditch shower curtains entirely and invest in a glass shower panel. Glass is hygienic, easy to maintain, and available in frosted or patterned designs for added privacy.
2. Wash Your Shower Curtain Weekly
Cleansing your shower curtain regularly is beneficial.
If glass isn't an option, consider forgoing liners and instead, wash your shower curtain more often. While frequent washing may accelerate wear, it's worthwhile for preventing mold and bacteria buildup.
Ideally, clean your shower curtain on a hot cycle weekly, but bi-weekly can suffice. High-quality hemp or linen shower curtain is worth considering.
These natural fibers handle high temperatures well and are durable while also offering a stylish range of shower curtain ideas.
Natural Cotton Shower Curtain is a safer choice.
3. Choose a PEVA Shower Curtain Liner
Consider using a PEVA liner.
Washing your shower curtain weekly is a commitment. If you know you won't keep up with that, you might still opt for shower curtain liners made from PEVA (polyethylene vinyl acetate). Dr. Savage states they 'are less likely to release harmful chemicals.'
However, PEVA isn't entirely safe. A 2014 study indicated that PEVA does emit potentially harmful VOCs, but the negative effects were noted in worms rather than humans. Unlike PVC, PEVA doesn't contain chlorine, which is linked to the release of VOCs.
If you prefer a clear shower curtain liner, PEVA is a better choice than PVC, but it's not completely 'safe'—just somewhat improved.
4. Clean with Vinegar Weekly
Use vinegar for cleaning every week.
To eliminate mold from your shower curtain, do it weekly using a safe non-toxic cleaner like white vinegar, known for its disinfecting qualities, according to Dr. Savage. Vinegar is a staple non-toxic cleaning solution you likely have in your kitchen.
Store-bought cleaners are an option, but preventing mold growth is much easier than removing it later.
Once a shower curtain is moldy, replacing it may be your best option.
Mold spreads rapidly, and missing a spot can lead to a quick return of the problem. The time spent scrubbing mold out is often not worth it. Dr. Savage agrees, advising, 'If you can't clean it, toss it!'
Vinegar is your go-to household item for keeping your shower space clean. This spray enhances your cleaning routine with added surfactants and essential oils like eucalyptus and rosemary. Note that this spray is intended for mold prevention and won't eliminate existing mold.
