Open the doors under your bathroom sink and what do you see? For most of us it is a dark pile of half used bottles, old sponges, and cleaning supplies we forgot we owned. The space is small, the pipes get in the way, and everything slides to the back where we cannot reach it.
The good news is that this cabinet is one of the cheapest spots in your home to fix. A few bins, one shelf, and a tension rod can turn the mess into a tidy setup in a single afternoon. Most of the ideas below cost less than a pizza night out.
Below you will find 22 under bathroom sink organization ideas that actually save space. Each one works around the plumbing, fits a real budget, and comes from setups that real people use every day. Pick the ones that fit your cabinet and start with just one.
Quick Picks
- Short on time? A two tier sliding organizer fixes most cabinets in under ten minutes.
- Renting? Tension rods, adhesive hooks, and over the door pockets need zero tools.
- On a tight budget? Dollar store bins plus a plastic tray cost less than 15 dollars total.
- Tiny cabinet? Use the door, the pipes, and vertical space before you buy anything wide.
Before You Start
- Measure first. Note the width, depth, and height of your cabinet, plus where the pipes sit.
- Pull everything out and toss expired products, dried out makeup, and empty bottles.
- Wipe the cabinet floor. A damp cloth with mild soap is enough.
- Group what is left: daily items, cleaning supplies, backups, and extras.
- Check for leaks around the pipes before you add anything new.
Tiered and Stackable Storage
1. Start With a Two Tier Sliding Organizer
This is the single most popular fix for under sink cabinets, and for good reason. Two stacked levels turn one dark shelf into two usable ones.
Look for a sliding two tier unit that fits around your pipes. Most are plastic or coated metal and cost 15 to 30 dollars. Set it on the cabinet floor, then place tall bottles below and short items on top. Sliding baskets pull out so nothing gets lost in the back.
Why it works: it doubles your storage without any tools or drilling. If you rent, this is the upgrade to start with. Measure the space under your pipes first so the top tier clears them.
2. Stack Clear Bins You Can See Through
Opaque bins hide clutter and create new clutter. Clear bins let you see exactly what is inside.
Buy a set of clear plastic bins with lids, usually 10 to 18 dollars for a pack of four to six. Stack two or three high on one side of the cabinet. Keep daily items in the top bin and backups below.
Why it works: you stop buying duplicates because you can see what you own. Wipe them out with a damp cloth every few months and they look new for years.
3. Add a Pull Out Drawer Unit
Deep cabinets waste the back half of every shelf. A pull out drawer brings the back to you.
Wood or metal pull out drawers cost 25 to 45 dollars and many install with screws in the cabinet floor. If you cannot drill, look for a freestanding rolling drawer tower instead. Load it with styling products, first aid items, and spare toiletries.
Why it works: you see and reach everything with one pull. This is the best pick for deep cabinets where your arm cannot reach the back wall.
4. Try an Adjustable Under Sink Shelf
Fixed shelves rarely fit around plumbing. Adjustable ones let you work with what you have.
Expandable under sink shelves have legs that move and shelves that widen to fit around pipes. They run 20 to 35 dollars. Assemble the shelf inside the cabinet, slide it into place, then adjust the height so tall bottles fit on the bottom. Similar shelf tricks also show up in our under kitchen sink organization ideas if you want more pipe friendly layouts.
Why it works: you build a second level around the exact shape of your pipes. No cutting, no tools, and it comes apart in minutes if you move.
5. Spin a Lazy Susan in the Corner
Corners under the sink are black holes. A turntable makes them usable.
A two tier lazy susan costs 12 to 25 dollars and fits neatly beside the pipes. Load it with small bottles, nail polish, or travel minis. One spin brings the back row to the front.
Why it works: nothing hides anymore. Pick a turntable with a raised lip so bottles do not slide off when you spin it.
Doors and Hidden Surfaces
6. Mount a Storage Rack on the Cabinet Door
The inside of the cabinet door is free storage most people ignore completely.
Door mounted racks cost 12 to 20 dollars and attach with screws or strong adhesive strips. Use one with deep pockets or cups for a hair dryer, flat iron, and styling products. Let hot tools cool before you store them.
Why it works: bulky hair tools move out of the main cabinet and onto the door, freeing a whole shelf of space. Close the door a few times before you load it up to make sure nothing blocks it.
7. Hang Clips and Hooks Inside the Door
Small metal items vanish in bins. On the door, they stay visible and handy.
Adhesive hooks cost 3 to 8 dollars for a pack and hold hair ties, headbands, and small bags. Clip style holders grip scissors, tweezers, and nail clippers. Press them onto a clean, dry door for the strongest hold.
Why it works: tiny tools get a home instead of sinking to the bottom of a bin. Swap the adhesive strips once a year so they stay stuck in bathroom humidity.
8. Hang an Over the Door Pocket Organizer
Fabric pocket organizers are cheap, light, and hold a surprising amount.
A canvas over the door organizer costs 8 to 15 dollars. Hook it over the cabinet door and fill the pockets with cotton pads, spare soap, sunscreen, and first aid basics. Roll the bottom pockets up if they bunch near the floor.
Why it works: you add six to ten pockets without using a single inch of shelf space. Choose a washable fabric so you can toss it in the laundry when it gets dusty.
9. Stick a Magnetic Strip on the Door
Bobby pins and tweezers love to hide. A magnetic strip keeps them in plain sight.
A short magnetic strip costs 5 to 12 dollars. Mount it inside the cabinet door with screws or heavy duty adhesive. Metal grooming tools snap right onto it: tweezers, nail clippers, small scissors, and bobby pins.
Why it works: you grab what you need in one second and never dig through a drawer again. Keep it out of reach of small kids since the tools are sharp.
10. Hang Spray Bottles From a Tension Rod
Spray bottles are tall and tip over easily. Hanging them solves both problems.
A small tension rod costs 4 to 10 dollars. Wedge it between the cabinet walls near the top, then hang spray bottles by their triggers. The bottles hang straight and stay put.
Why it works: bottles use empty air space instead of floor space, and you can see every label at a glance. This is one of the best renter friendly tricks on this list.
Bins, Baskets, and Trays
11. Sort Everything Into Labeled Bins
Bins without labels become junk bins. Labels keep the system honest.
Small bins cost 2 to 5 dollars each at discount stores. Make one bin for dental care, one for hair, one for cleaning, and one for backups. Add simple labels with a marker or a label maker.
Why it works: everyone in the house knows where things go, so the system survives longer than a week. Relabel as your needs change.
12. Warm It Up With Woven Baskets
Plastic works, but woven baskets make the cabinet feel calm instead of clinical.
Seagrass or wicker baskets cost 8 to 18 dollars each. Line them with a small cloth if you store tiny items so nothing pokes through. Use them for towels, toilet paper, and spare soap.
Why it works: baskets hide visual clutter and pull out like drawers. In a humid bathroom, pick baskets with a sealed finish so they do not absorb moisture.
13. Lay a Drip Tray Down First
Do this before anything else. A leak you catch early is a small problem. One you miss is not.
Plastic under sink mats cost 10 to 20 dollars. Trim to fit around the pipes if needed, then lay the mat on the cabinet floor before you add bins. It catches drips from bottles and slow pipe leaks.
Why it works: it protects the cabinet wood from water damage and makes cleanup a quick wipe. Check under it every few months for standing water.
14. Divide Space With Clear Acrylic Trays
Big bins swallow small items. Acrylic trays keep little things sorted and visible.
Stackable acrylic trays cost 12 to 22 dollars for a set. Use them for makeup, cotton swabs, hair ties, and samples. The clear walls mean you see everything without lifting a lid.
Why it works: small items stay grouped instead of scattering. Acrylic wipes clean easily, which matters in a damp cabinet.
15. Keep a Grab and Go Cleaning Caddy
If cleaning supplies live under the bathroom sink, keep them portable.
A handled caddy costs 6 to 12 dollars. Load it with your bathroom cleaner, glass spray, scrub brush, and gloves. When it is time to clean, grab the handle and go.
Why it works: you clean more often when the tools are easy to carry. The caddy also frees shelf space because it moves in and out of the cabinet.
Work Around the Pipes
16. Use a Two Piece Organizer Around the Pipes
Pipes eat the middle of the cabinet. Two piece organizers split to fit around them.
Split or U shaped organizers cost 20 to 35 dollars. The two halves slide in on either side of the drain pipe, then connect into one stable shelf. Store tall bottles in front and short items behind.
Why it works: it turns dead space around plumbing into real storage. Measure your pipe location first since drain positions vary from sink to sink.
17. Roll a Slim Cart Into the Side Gap
Many vanities have a few inches of dead space beside the cabinet. A slim cart fits right in.
Narrow rolling carts cost 15 to 30 dollars. Park one beside the vanity or in a tall gap inside the cabinet. Stock it with extra toilet paper, towels, and cleaning refills.
Why it works: wheels make it easy to pull out for full access. Lock the wheels if your floor slopes at all.
18. Hang Shower Caddies Around the Pipes
A cheap shower caddy works just as well inside a cabinet as it does in the shower.
Wire shower caddies cost 3 to 8 dollars each. Hang two or three from the pipes or from hooks on the cabinet walls, one on each side of the drain. Fill them with the bottles you reach for daily.
Why it works: it uses the awkward space right around the plumbing that nothing else fits. Choose rust proof wire so the caddies last in the damp air.
19. Fill Skinny Gaps With Narrow Bins
The last few inches beside the pipes often go unused. Narrow bins claim them.
Slim bins cost 3 to 7 dollars each. Slide them into the gaps between the pipes and the cabinet walls. They are perfect for toothpaste, floss, razors, and other slim items.
Why it works: every inch gets used, and slim items stop falling over behind bigger bottles. Buy bins with handles so you can pull them out easily.
Small Item Fixes
20. Store Hot Hair Tools on the Cabinet Door
Hair dryers and flat irons are bulky and awkward. The door handles them well.
Door mounted hair tool holders cost 10 to 18 dollars and include heat safe pouches or metal cups. Mount the holder on the inside of the cabinet door and drop the tools in after they cool.
Why it works: long cords stay tidy and hot tools stay away from water and bottles. Wait until tools are fully cool before storing them in fabric pouches.
21. Corral Tiny Items in Stacking Drawers
Bobby pins, hair ties, and samples need small homes or they spread everywhere.
Mini stacking drawers cost 8 to 15 dollars for a set of three or four. Dedicate one drawer to hair accessories, one to samples, and one to first aid basics. The drawers stack into a neat tower.
Why it works: tiny items stay sorted and you see them all at once. Label the front of each drawer if you share the bathroom.
22. Decant Into Matching Pump Bottles
Mismatched bottles look messy even when they are organized. Matching pumps fix that.
A set of refillable pump bottles costs 10 to 18 dollars. Pour shampoo, conditioner, hand soap, and lotion into matching bottles and add simple labels. Keep the big refill jugs in the back of the cabinet.
Why it works: the cabinet looks tidy and you save money buying refills instead of new bottles. Pick pumps that lock so they do not leak if they tip.
Budget Tips
- Start with what you own. Shoe boxes and food containers work as bins until you upgrade.
- Check the dollar store first. Bins, hooks, and trays there cost a fraction of big box prices.
- Buy one hero piece, like a two tier organizer, and fill the rest with cheap bins.
- Shop your home. A shower caddy, desk organizer, or spice rack can move under the sink.
- Wait for sales on storage brands. Sets often drop by a third during spring cleaning season.
- Measure twice so you buy once. Returns waste more money than a tape measure costs.
- Do one cabinet at a time. Spreading the budget across rooms leads to half finished systems.
Common Mistakes to Avoid
- Skipping the purge. Organizing expired products just hides the clutter.
- Buying before measuring. Pipes and hinges make many organizers a bad fit.
- Using cardboard. It sags and molds in bathroom humidity. Stick to plastic, metal, or sealed baskets.
- Blocking the shut off valves. Leave the water valves easy to reach in an emergency.
- Overfilling every bin. Leave a little breathing room or the system falls apart in a month.
Frequently Asked Questions
What is the best way to organize under a bathroom sink?
Start by pulling everything out, tossing what is expired, and measuring the cabinet. Then add one hero piece like a two tier sliding organizer or a pull out drawer, sort the rest into labeled bins by category, and use the door for hooks or a rack. Most people finish in one afternoon.
How do I organize around the pipes?
Use organizers made for the job: split or U shaped shelves that fit around the drain, a tension rod above the pipes for spray bottles, or wire caddies hung on either side. Always leave the shut off valves clear so you can reach them fast. For more ideas built for tight spaces, see our very small powder room storage ideas that actually work.
How do I keep it organized long term?
Follow a one in, one out rule: when a new bottle comes in, an old one goes out or gets used up. Labels help everyone put things back in the right spot. Do a five minute tidy once a month and a full reset once a year.
What should I store under the bathroom sink?
Daily toiletries, cleaning supplies, spare towels, toilet paper, first aid basics, and backup products all belong here. Keep medicines somewhere cool and dry instead, since bathroom heat and humidity can break them down.
Can I organize under the sink on a small budget?
Yes. Dollar store bins, a tension rod, adhesive hooks, and a repurposed shower caddy can transform a cabinet for under 25 dollars. Start with the cheapest fixes first and add one bigger piece later if you need it.
