The sink is a cavernous mystery box of domestic life, where bottles go to disappear, cleaning tools become relics, and occasionally, something drips ominously. While it may seem like the perfect hideaway for everything you don’t want to deal with, in reality, this space is a high-stakes storage area. The combination of water, pipes, and neglect can turn your organizational dreams into a soggy, sometimes moldy, chaotic mess (triple ick).
It starts innocently enough. One day, you toss a bottle of cleaner under the sink. Next, you’re cramming in extra trash bags, sponges, and perhaps a forgotten tool or two. Before long, the area is filled with questionable items that frankly should never have been there in the first place
To help you reclaim this space—and possibly prevent a plumbing disaster—it’s time to address the common culprits lurking under the sink. Do not store these things under your kitchen or bathroom sink, as innocent as it may seem initially.
1. Paper Products

Stashing paper towels, toilet paper, or napkins under the sink seems logical—until a leaky pipe transforms them into a pulpy nightmare. Water damage and paper products are a disastrous combination, leaving you with soggy, unusable clumps that belong in the compost bin rather than in your home.
Beyond the mess, storing paper near moisture makes it a magnet for mold and mildew, neither of which you want anywhere near your cleaning supplies or home. Keep these items in a dry cabinet or a pantry shelf, far from plumbing.
2. Cleaning Chemicals

While it might seem natural to store your arsenal of sprays and scrubs under the sink, combining these products in one confined space is risky. Bleach, ammonia, and other heavy-duty cleaners can react dangerously if their containers leak or mix, even unintentionally.
A small spill could escalate into a respiratory hazard or cause permanent damage to your cabinetry. Opt for a designated cleaning supply caddy stored in a more ventilated area. Or consider switching to more natural options, like castile soap and homemade sprays. This prevents potential chemical chaos and makes it easier to grab what you need without digging through a hazardous, potential volcano.
3. Perishable Food

Who hasn’t been tempted to toss an extra bag of potatoes or onions under the kitchen sink for “later”? While it may feel convenient, these foods are moisture-sensitive and prone to sprouting, rotting, or attracting pests when stored in damp or poorly ventilated conditions.
There’s nothing quite like discovering a forgotten potato colony thriving in the dark corners of your cabinet. Instead, store produce in a cool, dry place with good air circulation. A pantry or a dedicated basket on the counter works wonders.
4. Electronics

While it’s unlikely that you’re deliberately storing your laptop under the sink, smaller electronics like rechargeable toothbrush bases, razors, or even hairdryers sometimes find their way into bathroom cabinets. This is a mistake of epic proportions.
Water and electronics are natural enemies, and the damp environment under the sink practically guarantees corrosion or malfunction. Keep your gadgets away from plumbing. A wall-mounted shelf or an over-the-toilet organizer can keep electronics safe, dry, and functional. Your wallet—and warranty—will thank you.
5. Paint or Solvents

Storing paint cans or solvents under the sink might seem harmless (maybe?), but it’s a recipe for disaster. Changes in temperature, humidity, and proximity to plumbing can cause chemical degradation or leaks. Worse, if these substances come into contact with water, you might end up with an environmental and cleaning nightmare.
Paint and solvents should be kept in a cool, dry, and ventilated area—preferably in a garage or dedicated storage unit. Containers should be sealed tightly to avoid fumes or accidental spills.
6. Medications

It’s tempting to tuck a few pill bottles or a first-aid kit under the bathroom sink for convenience, but the humidity from showers and baths can degrade medicine quickly. Expired or compromised medications lose their effectiveness and may even pose risks if taken by mistake.
Keep your medications in a dedicated cabinet in a cool, dry space. A linen closet or a kitchen drawer away from appliances works perfectly. It’s an easy way to extend their shelf life and avoid accidental misuse.
7. Linens

Extra towels, washcloths, or even rags may seem like fair game for under-sink storage, but this is a trap. Humidity and occasional leaks can leave them damp, musty, or worse, a breeding ground for bacteria. Nobody wants to dry their hands with a towel that smells like mildew.
Instead, store your linens in a closet or basket that allows airflow. You’ll keep them fresher for longer and spare yourself the embarrassment of handing a guest a towel that’s seen too much.
8. Flammable Items

Anything combustible, such as aerosol cans, matches, or lighter fluid, has no business living under the sink. Leaks, heat (perhaps from a nearby stove), and confined spaces create a volatile combination that could lead to an accidental fire or explosion.
Store flammable items in a designated, safe area, away from heat and moisture. A garage shelf or a utility cabinet is much more suitable than risking an impromptu science experiment in your kitchen or bathroom.
9. Cosmetics

Under-sink cabinets are not the sanctuary for your beauty products that you might think. Moisture and heat can wreak havoc on makeup, creams, and other skincare items, leading to spoilage or bacterial contamination.
Even sturdy packaging can’t always hold up against these conditions. Store your cosmetics in a dry, cool drawer or vanity organizer to keep them fresh and effective. This will protect your investment and your skin’s health.
10. Anything with Sentimental Value

This one might seem a bit obvious, but it is worth mentioning, especially for anyone living in a small space. If you wouldn’t bury it in your backyard, don’t stash it under the sink. Family heirlooms, important documents, or cherished items are far too valuable to risk exposure to leaks, mold, or accidental damage.
Store sentimental items in a secure, dry, and temperature-controlled location. There’s no faster way to regret your storage decisions than fishing a soggy, ruined treasure out from behind the pipes.
11. Sharp Tools

Storing sharp tools like scissors, box cutters, or utility knives under the sink can lead to accidents. Digging through a cluttered cabinet is no time to discover an exposed blade waiting for your fingers (ouch!).
Keep sharp tools in a designated drawer or toolbox with safety covers when possible. This makes them easy to access while protecting your hands and your nerves.
12. Pet Supplies

Pet food, grooming tools, or other supplies may end up under the sink out of convenience. However, the combination of moisture and potential leaks can spoil food or ruin brushes, nail clippers, and other items.
Pet supplies are better stored in a dry, dedicated space where they can stay clean and ready for use. Or at a minimum, store them in an airtight bin. Your furry friends deserve better than soggy kibble or moldy brushes.
13. Household Appliances

Small appliances like toasters, blenders, or even hand mixers might seem like fair game for under-sink storage (that is, if you’re short on space), but the moisture and lack of ventilation can damage their electrical components. You don’t want to toast your bread with a toaster that has been stewing under your sink.
Store appliances in a dry cabinet or pantry shelf. This preserves their longevity and spares you the frustration of finding out your favorite gadget no longer works.
14. Anything Breakable

Glass jars, ceramic dishes, or other breakables are a risky choice for under-sink storage. One careless reach or a small flood can leave you with shattered remnants and a big cleanup. Maybe not the end of the world, but definitely an inconvenience that could be avoided.
Keep fragile items in a safer spot, such as a shelf or a cabinet with proper padding. Protecting these items spares you both the heartbreak and the broom work.
It can be hard to find a spot for everything in your bathroom or kitchen, but if you’re trying to cram too much there, it might be time to come up with a better storage plan and do some decluttering.
