Clever Bathroom Under Sink Storage Ideas You’ll Wish You Tried Sooner

So, here’s the truth: I’ve been side-eyeing the cabinet under my bathroom sink for weeks. You know the scene—half-empty shampoo bottles, a crusty can of hairspray from 2017, cotton swabs living their best chaotic life at the very back.

Every morning, I’d crouch down in my PJs, coffee in hand, rummaging like some kind of bathroom raccoon. And one day, mid-rummage, I thought: Nope. We’re done here.

That’s when the “organizing itch” hit me. If you know, you know. Once it starts, you can’t unsee the mess.

And let’s be real: under the bathroom sink is tricky. Between the plumbing pipes, the awkward height, and the limited space, it feels like a lost cause. But with some clever hacks, you can actually make it functional—and dare I say, pretty.

So, grab a fresh cup of coffee (or wine, no judgment), and let’s talk bathroom under-sink organization ideas that will make your mornings so much smoother.

Install a Pull-Out Organizer

Let’s start strong. A pull-out organizer basically turns your cabinet into a mini-drawer system. No more kneeling down and blindly grabbing bottles—you just pull and boom, everything’s there.

👉 Pro tip: Get one with smooth glides. Nothing kills the organizing mood faster than wrestling a stuck drawer while your curling iron is halfway unplugged.

Try a Hanging Caddy

If you’re working with a tiny bathroom (hello, apartment life), a caddy that hooks right over the cabinet door is a lifesaver. Toss in cleaning sprays, extra rolls of toilet paper, or your stash of skincare samples you’ll totally use one day.

Corral the Chaos with Clutter Catchers

Tiny items are the real villains under the sink—q-tips, bobby pins, nail clippers. Instead of letting them roam free, group them into small bins or containers. Bonus points if they’re clear—you’ll always know what’s inside.

Use an Over-the-Cabinet Wire Hanger

Sometimes the simplest ideas are the best. Pop a wire hanger over the door and suddenly you’ve got a spot for towels, cleaning gloves, or even your hair dryer.

Install an Adjustable Expandable Shelf

This is one of my favorites because it feels like a “grown-up move.” You’re literally building levels into your cabinet. Store toilet paper up high, cleaning sprays down low, and make peace with your pipes—they don’t have to ruin your storage dreams.

Try a 2-Tier System

If one shelf is good, two is better. Assign categories—beauty on top, cleaning on bottom. Not only does it keep things organized, but it helps you actually notice when you’re out of toothpaste before the crisis moment.

Hack It with an Over-the-Door Shoe Organizer

This one’s genius. Hang half of a shoe organizer inside the cabinet door and suddenly you have perfect little pockets for hairbrushes, lotions, face masks—basically your whole Sunday spa routine.

Use a Tool Organizer

No, not the garage kind (though, honestly, if it works, it works). Some under-sink organizers are literally designed like toolboxes—easy to pull out, with divided spaces. Feels weirdly satisfying.

Stackable Makeup Bins

If you’ve got more serums than counter space, stackable bins are your new bestie. Straight-sided ones maximize space, and you can dedicate a whole bin just to makeup, one to skincare, one to hair stuff.

Lazy Susan, But Make It Bathroom

Yes, Lazy Susans aren’t just for kitchens! Pop one under your sink and suddenly that “mystery back corner” is accessible. Spin to win your deodorant instead of digging like a raccoon.

Hang a Tension Rod with Baskets

This hack feels almost too clever. A simple tension rod can hold spray bottles by their nozzles. Add hanging baskets, and boom—instant vertical storage.

Repurpose a File Holder

Flat irons and hair dryers are always awkward to store. File holders or magazine racks keep them upright and safe from cord tangles.

 Add Command Hooks Inside the Door

Command hooks are like duct tape for renters—there’s nothing they can’t do. Use them to hang washcloths, loofahs, even small caddies. If you’re extra, install a mini pegboard for full-on adjustable storage.

Make It Match

This one’s less about function and more about joy. Matching bins, jars, or spray bottles instantly make your under-sink cabinet look Pinterest-worthy. And honestly, who doesn’t want to feel like their bathroom could be in a magazine?

What If You Have a Pedestal Sink?

I feel you—pedestal sinks are chic, but wow do they skimp on storage. Luckily, there are workarounds.

Add a Vanity Cabinet for Your Pedestal Sink

It basically hugs your pedestal sink and gives you hidden storage. Chic and functional.

 Floating Shelves Above the Sink

Take advantage of vertical wall space. Towels, skincare, even some cute plants if you’re feeling fancy.

Pedestal Storage Rack

Think of it as a little “belt” of storage wrapped around your sink. Keeps essentials right where you need them.

Lean a Ladder Shelf

Super trendy and surprisingly practical. Towels on one rung, baskets on another, skincare up top.

Add a Slim Cabinet Next to the Sink

Perfect for stashing all those little things that don’t fit elsewhere.

Standing Caddy

Tucks neatly beside or behind your pedestal. Bonus: you can move it around.

Install a Corner Shelf

Corners are underrated real estate. A floating corner shelf gives you easy access without cluttering counters.

Hang a Wire Basket

Simple, cheap, and suddenly your towels or extra toilet paper rolls have a home.

Roll in a Small Cart

If all else fails—rolling cart to the rescue. It’s mobile, stylish, and perfect for renters who can’t drill or install.

Final Thoughts: Your Under-Sink Glow Up

Organizing under the sink doesn’t have to be overwhelming. A few smart products, some creativity, and suddenly the most dreaded cabinet in your house is working for you, not against you.

And here’s the thing: every bathroom is different. Maybe you’ve got a full cabinet, maybe just a pedestal sink. Either way, you don’t need more square footage—you just need smarter storage.

So…what’s it gonna be? Are you Team Pull-Out Drawer? Team Lazy Susan? Or maybe Team “Finally Throw Away That Expired Hairspray”?

Either way, trust me—your future self (the one who can actually find the floss without a 10-minute scavenger hunt) will thank you.
