It reminded me of my own first apartment, when my under-sink space was a chaotic abyss. Over the years, I’ve learned that small spaces force you to think smarter, and under the bathroom sink might be the perfect spot to unleash a little creativity. So, let me share 10 of my favorite under-sink organization ideas I've tested in real homes and tiny apartments.1. Use Clear Stackable DrawersSeeing what you own at a glance stops you from buying duplicates. I love transparent drawers—they make it easy to store hair products in one, skincare in another. Just make sure you measure carefully; plumbing pipes can get in the way. I once solved this by sketching out dimensions on a room planner first.save pin2. Add a Tension RodA simple, cheap tension rod lets you hang spray bottles or cleaning cloths, freeing up the bottom space for baskets. It’s one of those “how did I not think of that earlier?” tricks to instantly declutter.save pin3. Install Pull-Out TraysNo more kneeling on the floor digging for your moisturiser. Pull-out trays bring everything forward with one tug—great for maximizing hard-to-reach spots. They do require a bit of installation effort.save pin4. Use Uniform ContainersMatching storage bins make even messy products feel visually neat. I recommend labeling them—bonus points if you use waterproof labels so you’re not replacing them every few months.save pin5. Over-the-Door Hooks or RacksThat forgotten door space can hold hair tools, spare towels, even toiletries. In one project, I used over-the-door wire racks to triple a client's storage space—without any drilling involved.save pin6. Tiered Shelving UnitsThese are lifesavers for awkward cabinet height. You can place everyday products on top and backup supplies below. I once plotted the placement using a free floor plan creator to make sure nothing collided with the sink pipes.save pin7. Lazy Susans for ToiletriesRotating trays aren’t just for the kitchen. Pop one under the sink and you’ll never lose your favorite serum in the dark back corner again.save pin8. Categorize with Small BasketsI separate first-aid supplies, extra toothbrushes, and skincare into different small baskets. That way, when my kid needs a plaster at 2am, I’m not rummaging through hair masks and cotton pads in frustration.save pin9. Stackable Shoe Boxes for Cleaning SuppliesClear shoe boxes are great for stacking vertically if your cabinet has the height. Just keep in mind ventilation—avoid sealing in any damp items.save pin10. Use Sliding Wire BasketsIf you want sturdy, long-term organization, sliding wire baskets are worth it. They’re especially great for heavy bottles or hair tools. I once modeled their placement with an kitchen layout planner before drilling any holes, just to avoid pipe conflicts.save pinFAQStart for FREEPlease check with customer service before testing new feature.Free Room PlannerDesign your dream room online for free with the powerful room designer toolStart for FREE
