Under the sink storage is a coveted and practical location for many households. It’s a hidden cabinet, often centrally located, that offers easy access to a plethora of items. But, did you know storing certain things there can actually be detrimental to their longevity and effectiveness?
As an avid home-organizer and interior design enthusiast, I’ve seen it all – from the surprisingly hazardous to the simply inconvenient. Join me as we explore seven items you should never store under your sink, along with some expert tips on how to make the most of this prime storage space.

Paper Products
It might seem convenient to stash your extra paper towels, toilet paper, or napkins under the sink, but it’s not ideal. These products can quickly absorb moisture, which can lead to mold growth and disintegration. Plus, in the case of a leak, they can become irreversibly damaged.
Instead, consider storing your paper goods in a dry, cool pantry or closet. Not only will this protect them from moisture damage, but it also frees up valuable under-sink real estate for items less susceptible to water damage.
Electronics or Electrical Items
Storing electronics or electrical items under your sink is a big no-no. The damp, humid environment can cause corrosion and damage to these items, and in worse case scenarios, could even lead to electrical fires.
When it comes to these items, it’s best to follow the old adage “better safe than sorry.” Store your hair dryers, straighteners, and other small appliances in a dry, well-ventilated area, away from potential water sources.
Medications
While it might be tempting to stash your medicine cabinet overflow under the sink, resist the urge. The fluctuating temperatures and humidity levels in this space can degrade the effectiveness of medications and even alter their chemical composition.
Medications are best kept in a cool, dry place, away from light and heat. A dedicated drawer or cabinet in your bedroom or living room is a much safer bet.
Food
Whether it’s canned goods, pet food, or cleaning supplies, storing food under the sink can attract pests and lead to contamination. The damp environment can also cause canned goods to rust, leading to potential health hazards.
Instead, dedicate a specific area in your pantry or cabinets for food storage. This way, your food items are kept safe, organized, and easily accessible.
Fine Linens
Those plush guest towels or fancy tablecloths should not find their home under the sink. The humidity can cause mildew and discoloration, ruining your fine linens.
Preserve the quality of your linens by storing them in a dry, cool linen closet or drawer. A touch of lavender sachets can also keep them smelling fresh and ready for your next dinner party or house guest.
Valuables
Storing valuables such as jewelry or important documents under the sink is a risky move. Not only is this space prone to leaks and potential water damage, but it’s also not the most secure place in your home.
For these items, consider a fireproof safe or a dedicated secure location in your home. This will provide you with peace of mind and protect your valuables from potential damage.
Books
Your cherished cookbooks or home improvement guides might seem at home under the sink, but paper and moisture just don’t mix. Books can easily warp, discolor, or develop mold in this environment.
Keep your books safe and sound on a bookshelf, cabinet, or dedicated book storage area. This will ensure they stay in perfect condition for your next culinary adventure or DIY project.
In conclusion, while the under-the-sink cabinet can be a convenient storage spot, it’s not suitable for everything. By being mindful about what you store there, you’ll protect and extend the life of your belongings. So, next time you’re about to stash something under the sink, take a moment to consider if it truly belongs there. Happy organizing!
