Let’s cut to the chase: I’ve spent the last 7 years running a bathroom holder manufacturing business, fielding every random, unexpected question about our products from customers, and the one that’s stuck with me longer than most is: “Can a bathroom holder be used for storing contact lens cases?” Bathroom Holder

When I first got that email from a 28-year-old graphic designer in Portland last spring, I almost laughed. Our line of bathroom holders is designed for toothbrushes, razors, floss, those tiny travel-sized mouthwash bottles that take up half your medicine cabinet—basic, functional bathroom stuff. But the more I thought about it, the more I realized this wasn’t just a random question. It was a perfect example of how people repurpose everyday household items in smart, practical ways, even when they’re not marketed for that exact use. As someone who’s spent years testing our products for bathroom-specific needs, I knew there was more to this question than a simple yes or no.
First, let’s break down what a bathroom holder is, at least the ones we make. We craft all our holders from BPA-free, food-grade PP plastic for the countertop line we sell most of, and our wall-mounted options are finished with rust-resistant stainless steel and silicone seals. Every holder we design has intentional features: drain holes at the bottom, wide enough spacing to prevent overcrowding, and material that won’t retain mold or mildew in high-humidity environments—things we test for in our in-house lab every quarter. Now, contact lens cases. Most people don’t realize contact lens cases have very specific storage needs. They need to stay dry between uses, not sit in standing water, and their small, hollow crevices can trap moisture if they’re not given room to air out.
That’s where the bathroom holder’s design gets interesting. Let’s start with the obvious fit: size. Our small countertop holders, the ones that hold 4 toothbrushes and a toothpaste tube, have individual slots that are roughly 1.5 inches wide and 3 inches deep. A standard contact lens case is only about 1 inch in diameter, so it fits perfectly in those slots—no forcing, no jostling. What about larger holders? Our under-sink organizer, the one with 6 open compartments, works even better for people who have multiple contact lens cases (for backup, or if you switch between daily and monthly disposables) or even travel-sized contact lens kits with solution bottles.
Now, the science part, which is what actually makes this repurpose safe. Bathroom environments are high in relative humidity—often 50-70% after a hot shower, per the International Residential Code’s bathroom ventilation guidelines. Mold, mildew, and bacteria thrive in these conditions, especially on porous surfaces, but our bathroom holders are non-porous. That means they don’t absorb moisture, so even if a contact lens case leaks a little solution or water, the holder doesn’t hold onto it. The drain holes we add to every base? Those are critical. A contact lens case that’s left on a closed shelf or in a drawer often gets stuck in a small pool of water that never evaporates, which is a breeding ground for germs. But when you set that same case in a bathroom holder’s slot, the drain holes let any excess moisture drip away, so the case stays dry enough to prevent bacterial growth.
Wait, but let’s get specific about contact lens hygiene, because that’s the line between a clever trick and a health hazard. The American Academy of Ophthalmology (AAO) has very clear guidelines for contact lens care: contact lens cases must be cleaned with contact lens solution after each use, rinsed thoroughly, and allowed to air dry completely before being used again. They also recommend replacing contact lens cases every 3 months, or immediately if they show signs of dirt, cracks, or mold. So if you’re using a bathroom holder to store your contact lens cases, you have to make sure the holder supports that drying process. Let’s test that against our products: our holders don’t have any crevices or corners where moisture can get trapped, right? The slots are open at the top and bottom (for countertop models) or have open sides (for wall-mounted and under-sink models), so air circulates freely around each case. That’s exactly what the AAO says helps prevent the buildup of harmful bacteria that can cause eye infections.
I’ve heard a lot of pushback from customers who say “but bathroom holders are for toothbrushes, not contact lenses.” Here’s the thing: toothbrushes also harbor bacteria, per a 2021 study from the Journal of Clinical Dentistry that found toothbrushes can have up to 10 million bacteria per bristles after 24 hours. Our bathroom holders are designed to mitigate that same risk that applies to contact lens cases. The only difference is that contact lens cases are smaller, so they fit into the smaller slots, and the solution they hold is sterile, while toothbrushes are just being rinsed with tap water. But the core requirement—airflow, non-porous material, moisture drainage—is exactly the same.
But it’s not all perfect, and I want to be transparent here, because that’s how we do business. There are some caveats to using a bathroom holder for contact lens cases, and you can’t just grab any random holder from your junk drawer and use it. First, if your bathroom holder is made from porous material—like cheap acrylic, untreated wood, or porous ceramic—don’t use it. Those materials absorb moisture, so even the drain holes won’t prevent mold from growing inside the holder, which can then transfer to your contact lens case. That’s a big no-no for eye health, and we’d never recommend our holders for that if we thought they’d be unsafe. Second, don’t overcrowd the slots. If you cram 10 contact lens cases into a slot that’s meant for a toothbrush, you block airflow, and moisture gets trapped. Keep the number to one case per slot, same as you would for a toothbrush. Third, if you have a holder with a closed lid (some of our larger under-sink models have lids for dust protection), make sure you leave the lid partially open or off while the cases are drying. A closed lid traps moisture, which defeats the whole purpose.
I started this business because I noticed that too many bathroom products are one-and-done, marketed for exactly one use, even if they’re built in a way that works for others. That graphic designer in Portland who emailed me last year? She told me she was tired of her contact lens cases getting lost in her makeup bag or her bathroom drawer, and she wanted a way to keep them within easy reach while she was putting in her lenses in the morning. She tested one of our small countertop holders for a month, and emailed me back to say she’d had no issues with moisture buildup, and her cases were always where she needed them. That’s the kind of practical use that makes me love this job—helping people solve small, everyday problems with products that are already made, instead of forcing them to buy something new that does the exact same thing.
Of course, if you’re looking for a product specifically marketed for contact lens storage, there are plenty of those on the market. But if you already own a bathroom holder that meets the right criteria—BPA-free, non-porous, with drain holes, proper size slots—then yes, it works just as well for contact lens cases as it does for toothbrushes and razors. And if you don’t have one yet, why not get a holder that does double duty? You don’t need a separate storage solution for your contact lenses, when a product you’re already buying for your bathroom works perfectly.
Wait, let’s circle back to the hygiene angle, because that’s the most important part. The AAO says that 90% of eye infections related to contact lens use are caused by poor case care. So if you’re storing your case in a place that lets it dry properly, you’re already taking the first step to preventing those infections. Our bathroom holders are designed to keep things dry and organized in a high-moisture environment, so that’s exactly what they do for contact lens cases. I’ve tested this myself—for about two months last year, I used one of our small wall-mounted holders to store my own contact lens cases, and I never had a case that felt damp or smelled like mildew, which is something that used to happen when I left them in my medicine cabinet.
Another thing people don’t think about: travel. If you’re going on a trip, you need a place to store your contact lens case that’s easy to carry, and that keeps it separate from your other toiletries. Our smaller countertop holders are light enough to toss in a suitcase, and the slots keep the case from shifting around and getting damaged. The larger under-sink organizers are great for home use, but if you need something portable, our travel-sized bathroom holders (the ones that fit in a hotel bathroom counter) work perfectly for contact lens cases too.
I know this blog might sound like I’m pushing our products, and I guess I am. But not in a salesy way—this is real advice from someone who’s been making and testing bathroom holders for almost a decade. I’ve seen customers use our holders to store everything from hair ties to small first-aid kits, and none of them are wrong for doing it. The key is that the product has to meet the functional needs of what you’re storing, whether it’s a toothbrush or a contact lens case. And our holders? They meet those needs perfectly.

If you’re someone who’s been thinking about testing this out, go for it. Just make sure your holder is non-porous, has proper drainage, and gives your contact lens case enough room to air out. And if you’re in the market for a new bathroom holder that’s safe for this kind of repurpose, I’d be happy to walk you through our line—we’ve got sizes for every bathroom, from small apartment counters to large master baths. If you have questions about compatibility, or if you want to learn more about our testing process for hygiene, feel free to reach out. I’m always happy to chat about what our products can do, beyond their original intended use.
