Update: Death of a Plastic Shower Curtain, Part 3

Last updated on March 27, 2023.

A couple of years ago, I wrote about the death of my vinyl plastic shower curtain liner, and my decision to never buy plastic liners again. Plastic liners off-gas toxic chemicals in your home and the curtains can end up in the ocean after disposal. I tried using the fabric curtain without a liner, but it quickly grew mildew and mold and after washing it several times, it started to fall apart. So in my second article, I repaired it and then coated the bottom half of the curtain (where the most moisture accumulates) with Otter Wax.

This, however, was a complete failure.

The cloth curtain grew mildew and mold even quicker, and to the point that I could no longer clean it. I don’t know if I spread the Otter Wax unevenly or just didn’t apply enough onto the fabric. It seemed that the nooks and crannies of the fabric weave held in moisture easier. Perhaps Otter Wax was not meant to prevent mold growth in fabric that is constantly in a warm, moist environment.

No More Plastic

I refuse to give up and go back to vinyl/plastic shower curtain liners. Since first writing about my shower curtain pursuit in 2018, I have learned a lot about the chemical compositions of plastics and how they adversely affect human health. Captain Charles Moore wrote about this subject in his book, Plastic Ocean:

“Who doesn’t know that potent ‘plasticky’ smell that somehow we’ve come to associate with ‘new’ and ‘clean’?”

He cited a 2008 study that quantified fumes off-gassing from PVC shower curtains, in which they logged 108 chemicals, mostly volatile organic compounds (VOCs) and phthalates. “Prolonged exposure to these chemicals is associated with respiratory irritation, headaches, nausea, and potential harm to the liver, the kidneys, and the central nervous system. They can also cause cancer.” There are now many studies about off-gassing plastics and they all indicate the same health problems.

Failing Forward

If you’ll recall from my second post, the gray cloth shower curtain was intended to be used with a plastic liner and not meant to withstand daily use without one. So I learned to invest in a better cloth shower curtain, one intended to be used solely. The lower cost of plastic shower curtains is not worth the environmental consequences nor the risks to my family’s health. I decided to purchase a hemp canvas shower curtain. Hemp fabrics inhibit mold and mildew growth which makes them a great option for shower curtains. It was expensive but it was the best option for our home. I’ve had it for just over one year now, and I will share my trials and errors with you.

Cloth shower curtains require special care

Overall, I like this shower curtain, but it is not perfect. We adjusted the curtain rod because this curtain was much longer than our old shower curtain. But then the first time I washed and dried it, the curtain shrunk by about 7 inches! So again, we had to adjust the shower curtain rod, which again marked up the walls. I learned that it is best to simply wash it in the machine and rehang it to dry.

The hemp shower curtain came with specific care instructions, and although they appeared unprofessional, I tried to follow them. We draw the curtain outside of the shower to let it dry out after every shower. But I do not launder it weekly. I have had some mold growth so I have boiled it in hot water to kill it per the instructions and that seemed to work.

However, upon writing this post, I discovered that the instructions have been updated on the website and are different from the ones I received in the package. They now recommend washing it every few weeks instead of weekly. If mold appears, they suggest washing the shower curtain with half a cup of Borax and/or oxygen bleach in the machine on the delicate cycle. Last, they indicate to hang dry it – I wish I’d known that before drying it in the dryer and thus shrinking it that first time!

Shopping for Shower Curtains

Obviously, stay away from plastic shower curtains, including plastic-derived fabrics such as polyester, nylon, and microfiber. These synthetics can cause as much environmental damage as vinyl, especially when laundered. Some of these “fabric” polyester curtains even contain chemicals to make the plastic fabric water-repellent. Ingredients such as perfluorooctane sulfonate, a chemical known to cause cancer and has a Proposition 65 warning, are just one example I found on Kohls’ website. If you do happen to find a cotton and “chemical-free” shower curtain at a department store, these almost always recommend using a liner with the curtain, defeating the purpose of switching to a fabric shower curtain. I’ve found examples of those on Target’s website.

Look for hemp or a hemp cotton blend. If you can’t find a hemp curtain in your price range, get a cotton curtain so that you can wash it regularly. Read the fine print so you know exactly what type of fabric it is. Check the details as some fabric curtains have a disclaimer such as, “recommend using with a shower curtain liner.” This often indicates that the curtain cannot withstand constant water exposure and will not last very long. Also, read the reviews to help determine durability and quality.

Another option is reclaimed sailcloth, which I mentioned in a previous post. This is what I’d like to purchase someday as long as I can find one made of authentic, reclaimed sailcloth. These generally run in the $200-$300 range and I frankly cannot afford one right now.

Other than having glass doors professionally installed, I’m not sure there is a perfect replacement for a plastic shower curtain. Although a better option than plastic by far, the mold-resistant hemp canvas shower curtain is not perfect. This curtain does not round or cover the ends of the shower the way a plastic curtain does, so some water gets out and we have to clean up small amounts of water on the walls and floors after each shower.

Unfortunately, the curtain has begun to deteriorate the fabric on the bottom section where it gets the wettest and where mold grows. I think I’m going to hem it where the holes are rather than trying to patch it. It might be my fault for not laundering it often enough. But I guess I was hoping for more durability for the amount I paid for it. Still, this is the best solution I have at this time, so I will continue with this curtain. If I have to do something different, I’ll be sure to update this post with a Part 4!

Update: Death of a Plastic Shower Curtain, Part 2

Last updated on December 3, 2020.

If you read my previous article about the death of my plastic shower curtain liner, you’ll recall that my goal was to find a plastic-free alternative. First, I decided that we would try getting by with only the cloth shower curtain. And I told you I’d update you on how that went!

The Shower Curtain

I purchased the cloth shower curtain at Bed Bath & Beyond back in 2015. As I mentioned before, I also had a plastic liner to protect it. The cloth one is made of 100% cotton and listed as machine washable on their website. But it also indicated “liner not included,” meaning it was intended to be a  decorative curtain, protected by a separate liner. I think I knew that at the time I purchased it, but back then I thought I would always have a plastic/vinyl shower curtain liner.

However, the shower curtain has not withstood daily use in the shower and two subsequent washing machine cycles. The curtain got very dark and dingy with a few mold spots. After I washed it the first time in the washing machine, I noticed some small holes and areas where the fabric was starting to deteriorate. But I rehung it for a couple of more months and it got gross again.

Washing the Shower Curtain

This week, it was time to wash it again. In recent weeks, I discovered Otter Wax, which is a waterproofing wax made of different waxes, including beeswax. This product does not contain paraffin, silicone, or other petroleum-based synthetic ingredients. So I ordered some and planned to waterproof my shower curtain.

The instructions are clear that the fabric item must be cleaned and dried, but also be able to cure for 24 hours. Since we only have one shower, I had to time this perfectly around three people’s daily use of the shower. I took it down after the last shower one morning this week and worked on it right away to make sure I had enough time.

The night before I pre-treated it by spraying 3% hydrogen peroxide on the inside of the curtain, to deal with the mold spots. (I avoid using bleach whenever possible because of its toxicity, and I keep reading that bleach just changes the color of mold and doesn’t actually kill it.) I let it sit on the curtain for a while and rinsed it off later. It did not make any visible difference but I had hoped it killed the mold.

Next, I put it in the washing machine on the casual cycle (which is supposed to be gentler during the spin cycle than the regular cycle). But here’s what happened!

This is the damaged shower curtain. Thankfully the damage was isolated to the bottom portion of the curtain.

Oh, dear.

My initial thought was that I would have to purchase a new hemp shower curtain. But money is tight these days, so I decided not to give up on this curtain just yet!


Damage this bad cannot be mended or patched up. My only option was to hem the shower curtain. I needed to cut off 7 inches (up to the highest points of the damaged areas) and then I used a half-inch folded twice to make a new bottom hem. This meant I was going to lose a total of 8 inches off the bottom.

I cut, pinned, and then held it up to the shower curtain rod to see if it would still be long enough before I completed it. It seemed fine and the curtain rod is adjustable, so I went ahead and hemmed the curtain.

The last step was to apply the Otter Wax on the fabric, which took some elbow grease. I only ended up having enough wax to do the lower half of the shower curtain (and just enough time before going to work that day). My bar is only the size of a pat of butter now!

After it was coated, I allowed about 22 hours to cure. I left it out on my dining room table at room temperature. The next morning, my husband and I hung it back up. We did have to lower the shower curtain rod a couple of inches (which lightly damaged the paint, so I’ll have to touch that up this weekend). But the shorter length is not that noticeable.

The next step

It’s not perfectly coated, so I may need to apply another layer. For now, I’m going to see how it repels water. I followed the instructions on the paper label, but I’ve since watched YouTube videos about how others use OtterWax. Some users recommended using a hairdryer on low to make the wax easier to spread onto the fabric. Others recommended ironing the entire piece on low after rubbing the bar into the fabric. This is the option I will try should I need to make it more waterproof.
