15 Practical Bathroom Organization Under Sink Ideas For Busy Homes

Remember that time you opened your bathroom cabinet and everything came tumbling out like a poorly executed game of Jenga? Yeah, me too.

Last week, actually, when I got bonked on the head by a rogue bottle of shampoo. That’s when I knew something had to change.

If you’re anything like me, your under-sink space probably looks like a tornado hit a beauty supply store. But here’s the thing – organizing that chaos doesn’t require a degree in interior design or a trust fund.

I’ve tested pretty much every storage solution out there (my husband calls it an obsession, I call it research), and I’m about to share the 15 best ideas that actually work for real people with real lives.

Pull-Out Sliding Drawers

Let me start with my absolute favorite solution that changed my morning routine forever. Pull-out sliding drawers transform that awkward, deep cabinet space into something you can actually use without getting on your hands and knees.

I installed these bad boys about six months ago, and honestly? Game changer. You know how you always lose stuff in the back of the cabinet? Well, these drawers slide out completely, giving you access to every single item. No more archaeological expeditions to find that one hair product you swear you bought last month.

The best part is you don’t need to be Bob the Builder to install them. Most come with simple mounting brackets that attach to your existing cabinet frame. I managed it with just a drill and about 30 minutes of mild swearing 🙂

Why They Work So Well

Heavy-duty rails handle all your bottles and products without sagging. Mine hold everything from bulk shampoo bottles to my collection of face masks I’ll definitely use someday. The smooth gliding action means you won’t wake up the whole house during those early morning routines either.

Tiered Shelf Organizers

Ever feel like you’re playing Tetris every time you put something away? Tiered shelf organizers solve that problem by creating vertical storage levels that actually make sense.

These stepped platforms basically double or triple your storage space by using the vertical height you’re already paying rent for. I keep my daily essentials on the lower tier and backup supplies up top. Smart, right?

The expandable ones are particularly genius. You can adjust them to fit around that annoying pipe that seems to exist solely to make organization harder. Mine extends from 15 to 25 inches, which means it works perfectly whether you have a pedestal sink or a full vanity.

Making the Most of Tiers

Here’s what I’ve learned works best:

• Bottom tier: Daily use items (toothpaste, face wash, deodorant)
• Middle tier: Weekly items (hair masks, exfoliants)
• Top tier: Bulk supplies and rarely used products

Stackable Storage Bins

Okay, can we talk about how stackable bins are basically the Swiss Army knife of bathroom organization? They’re cheap, versatile, and somehow make even my chaotic collection of products look Instagram-worthy.

I use clear ones because I like to see what’s inside without playing guessing games at 6 AM. But if you’re more of a “hide the mess” person, solid colors work great too. The key is getting ones with interlocking lids so they don’t slip around when you stack them.

Pro tip from my own bathroom disasters: measure your cabinet height first. I once bought bins that were perfect… except they were half an inch too tall when stacked. Learn from my mistakes, people.

Bin Organization Strategy

Group similar items together and you’ll never lose track of anything:

• One bin for hair care
• One for skincare
• One for those random samples you’re totally going to use
• One for cleaning supplies (keep these separate!)

Hanging Door Racks

Why waste that perfectly good door space? Hanging door racks turn the inside of your cabinet door into prime real estate for all those bottles and tubes that otherwise create chaos.

I’ve got two different styles going on in my bathrooms. The wire basket type in the master bath holds all my hair tools, and the pocket organizer in the guest bath stores cleaning supplies where kids can’t reach them. Both cost less than a fancy coffee drink and took about two minutes to install.

The over-door hooks don’t damage your cabinets either, which is crucial if you’re renting. Been there, lost that security deposit – never again.

What to Store on Door Racks

Best items for door storage:

• Frequently used products (you want easy access)
• Lightweight items (heavy stuff can damage doors)
• Flat or narrow products that don’t stick out too far
• Cleaning supplies in upper racks away from cosmetics

Lazy Susan Turntables

Who says Lazy Susans are just for kitchens? These rotating platforms are absolute lifesavers under the sink, especially in those awkward corner cabinets where things go to disappear forever.

I’ve got a two-tier one that holds all my bottles upright and accessible. No more knocking everything over to reach that one product in the back. Just spin and grab – it’s almost fun, if organizing can be called fun (spoiler: it totally can).

The non-slip surface is key here. You don’t want your expensive serums doing the cha-cha every time you rotate the platform. Mine has a rubberized base that keeps everything stable even when I’m in a rush.

Maximizing Your Lazy Susan

Get the most out of your turntable:

• Place taller items toward the center
• Keep similar products grouped together
• Leave a little space between items for easy grabbing
• Choose one with raised edges to prevent roll-offs

Clear Acrylic Containers

Let’s be real – half the battle of staying organized is being able to see what you have. Clear acrylic containers make everything visible and somehow make even cheap products look fancy.

I started using these after throwing away my third expired sunscreen that I forgot I had. Now everything’s visible, labeled, and I actually use what I buy. Revolutionary concept, right?

The modular ones are where it’s at. You can mix and match sizes to create a custom system that fits your exact space. Plus, they’re super easy to clean when (not if) something spills.

Container Categories That Work

My system that’s survived two years and counting:

• Tall container: Hair products and tall bottles
• Wide shallow container: Makeup and small items
• Medium squares: Cotton balls, Q-tips, hair ties
• Narrow container: Toothbrushes and toothpaste

Adjustable Under-Sink Shelves

Remember playing with those expandable toy robots as a kid? Adjustable shelves work the same way but for grown-up problems. They expand to fit your exact cabinet width and work around pipes like magic.

I’ve tried three different brands, and honestly, the mid-price ones work just as well as the expensive versions. The key feature you want is sturdy leg locks that won’t collapse under the weight of your product collection.

Mine creates an extra shelf that literally doubled my storage space. Plus, you can adjust the height based on what you’re storing. Tall bottles on bottom, short stuff on top – it’s not rocket science, but it works.

Installation Tips

What I learned the hard way:

• Measure twice, buy once (seriously, measure your cabinet)
• Level it properly or everything rolls to one side
• Don’t overload it – respect the weight limit
• Leave room to reach the shut-off valves

DIY PVC Pipe Dividers

Hear me out on this one – PVC pipes aren’t just for plumbing anymore. Cut them into sections and you’ve got perfect holders for hair tools that would otherwise tangle into an unholy mess.

I made mine for less than $10 and about 20 minutes of effort. Each pipe section holds a different tool – curling iron, straightener, hair dryer – all standing upright and ready to grab. It’s like a utensil holder but for your beauty tools.

The best part? You can customize the heights and diameters to fit your specific tools. My husband even spray painted ours to match the bathroom decor. Who knew PVC could look chic?

DIY Instructions

Super simple process:

• Buy PVC pipe (4-inch diameter works for most tools)
• Cut into 6-10 inch sections
• Sand the edges smooth
• Optional: spray paint or cover with contact paper
• Secure together with PVC glue or just place in a bin

Over-the-Cabinet Tension Rods

This might be the cheapest hack on this list, but don’t let that fool you. Tension rods under the sink create instant hanging storage for spray bottles and cleaning supplies.

I installed mine in about 30 seconds (not exaggerating), and suddenly all those bottles with triggers that never stand up properly had a home. The rod sits near the top of the cabinet, leaving the bottom clear for bins or drawers.

FYI, get the heavy-duty ones. The cheap ones will bow under weight and you’ll find everything on the floor one morning. Ask me how I know…

Hanging Storage Ideas

What works best on tension rods:

• Spray bottles (hang by the trigger)
• Small baskets with hooks
• Cleaning cloths on clips
• Rubber gloves
• Small caddies for sponges

Labelled Storage Baskets

I know what you’re thinking – labels are for type-A neat freaks. But hear me out. Labeled baskets mean everyone in your house (looking at you, kids and partners) can actually put things back where they belong.

My label maker is basically my best friend at this point. Every basket under my sink has a clear label, and miracle of miracles, my family actually follows the system. Most of the time. Okay, sometimes. But it’s better than nothing!

The woven baskets look nicer than plastic bins IMO, and they come in sizes that fit perfectly in most cabinets. Plus, they have handles, making it easy to pull out the whole basket when you need something from the back.

Labeling Strategy

Keep it simple:

• Use broad categories (Hair, Face, Body)
• Make labels large and clear
• Consider pictures for kids’ bathrooms
• Laminate labels for durability
• Update labels when you reorganize

Hanging Mesh Pockets

These mesh organizers are like the pocket protector of bathroom storage – nerdy but incredibly functional. They hang from a simple hook or rod and create multiple pockets for small items that otherwise get lost.

I use mine for all those sample sizes and travel products that multiply like rabbits. Each pocket holds different categories, and the mesh means I can see everything at a glance. No more buying travel toothpaste when I already have six tubes hiding somewhere.

The breathable mesh also prevents that musty smell that sometimes develops in closed cabinets. Bonus points for being machine washable when things get grimy.

Pocket Organization Ideas

How to use those pockets effectively:

• Top pockets: Frequently used small items
• Middle pockets: Backup supplies
• Bottom pockets: Heavier items that won’t stretch the mesh
• Side pockets: Flat items like razors or nail files

Small Drawer Units on Wheels

Rolling drawer units are basically portable organization stations that slide in and out of your cabinet as needed. Think of them as dresser drawers for your bathroom stuff.

Mine has three drawers and lives under the sink, but I can roll it out when I’m doing my skincare routine. Each drawer holds different categories, and the wheels mean I’m not crawling under the sink every morning.

The clear plastic versions let you see what’s inside, while solid ones hide the chaos if you’re not quite ready for full transparency with your organization skills :/

Drawer Organization System

My tried-and-tested setup:

• Top drawer: Daily essentials
• Middle drawer: Weekly-use items
• Bottom drawer: Bulk supplies and backups
• Label each drawer (trust me on this)

Magnetic Spice Jars for Small Items

Okay, this one’s a bit unconventional, but magnetic containers stuck to the inside of your metal medicine cabinet or a magnetic board are genius for small items.

I use these for bobby pins, hair ties, safety pins – all those tiny things that disappear into the void of regular storage. Each jar is labeled and visible, so I never have to dump out entire drawers looking for one bobby pin again.

The clear jars let you see when you’re running low on supplies. Plus, they look weirdly satisfying all lined up in rows. Is it just me who finds organized containers deeply satisfying?

Small Item Storage Tips

What works in magnetic jars:

• Hair accessories
• Cotton swabs (in smaller quantities)
• Medication (if cabinet locks)
• Small makeup items
• Travel-sized products

Foldable Fabric Bins

Collapsible fabric bins are perfect for renters or anyone who likes flexibility in their organization. When you don’t need them, they fold flat. When you do, they pop open to hold a surprising amount of stuff.

I keep seasonal items in mine – sunscreen and beach stuff in summer, heavy moisturizers in winter. When the season changes, I can fold the empty bins and store them until needed again.

The fabric is usually washable too, which is essential when you’re storing bathroom products that occasionally leak. Nothing worse than a permanently stained organizer.

Seasonal Storage Strategy

How I rotate my bins:

• Summer bin: Sunscreen, aloe, beach hair products
• Winter bin: Heavy creams, lip balm collection
• Travel bin: Minis and samples
• Guest bin: Extra supplies for visitors

Under-Sink Caddy with Handles

Last but definitely not least, a portable caddy with handles is perfect for those deep cabinets where things get lost in the back. You can pull the entire caddy out, grab what you need, and slide it back.

I keep my cleaning supplies in one because I can grab the whole thing and carry it around the bathroom when I’m cleaning. No more multiple trips back and forth to the cabinet.

The divided compartments keep bottles upright and organized. Mine even has a spot for the scrub brush that keeps it from touching other items. Because nobody wants their toothpaste hanging out with the toilet cleaner.

Caddy Selection Tips

What to look for:

• Sturdy handles that won’t break under weight
• Waterproof material for easy cleaning
• Dividers that fit your products
• Size that fits your cabinet with room to pull out

Bringing It All Together

So there you have it – 15 ways to transform that disaster zone under your sink into an organized paradise. Well, maybe paradise is overselling it, but at least you won’t get injured by falling shampoo bottles anymore.

The key to making any of these solutions work is picking what fits your specific needs and space. I use a combination of pull-out drawers, labeled baskets, and a lazy Susan in my master bath. The guest bath gets the simpler treatment with bins and door racks.

Start with one or two solutions and build from there. Rome wasn’t built in a day, and neither is the perfectly organized bathroom. But trust me, once you get even one of these systems in place, you’ll wonder how you ever lived with the chaos.

Remember, the best organization system is the one you’ll actually use. Don’t create something so complicated that you can’t maintain it. Keep it simple, keep it functional, and maybe – just maybe – you’ll actually enjoy opening that cabinet door each morning.

Now if you’ll excuse me, I need to go reorganize my under-sink area again. What? I said it was research!
