Under Sink Organization Ideas That Actually Work

There is something about the cabinet underneath the sink that makes organization feel almost impossible.

You start with good intentions. You put a few cleaning products underneath, maybe some trash bags and sponges, and tell yourself you’ll keep everything neat.

Then a few weeks later, you’re reaching past three half-empty bottles just to find a sponge.

I’ve been there more times than I care to admit.

The problem usually isn’t that you have too many things. It’s that the space underneath a sink is awkward. You have plumbing taking up valuable room, a deep cabinet that’s difficult to reach into, and products of completely different shapes and sizes all competing for the same space.

The good news is that you don’t need a huge cabinet or an expensive custom storage system to make it work.

With a few simple changes, you can turn that messy cabinet into a space where everything has a place and, more importantly, you can actually find what you’re looking for.

If your under sink cabinet has become a catch-all for cleaning supplies, extra sponges, garbage bags, and random household items, these under sink organization ideas will help you make better use of every inch.

If you’re tackling more than just the sink, our guide to storage solutions for small spaces is a great next stop.

Why Under Sink Cabinets Are So Difficult to Organize

Before you buy a bunch of containers, it helps to understand why this particular cabinet becomes messy so quickly.

The biggest issue is the plumbing.

Unlike a normal cabinet, you can’t simply place a large storage bin in the center and use the entire shelf. The pipes, drain, and sometimes garbage disposal divide the available space and create awkward areas that can be difficult to use.

Then there are the products themselves.

Cleaning bottles are tall, sponges are tiny, garbage bags come in rolls, dishwasher tablets come in boxes, and reusable cleaning cloths tend to disappear into the back of the cabinet.

Without a system, everything ends up stacked wherever there happens to be room.

That’s why the best under sink storage ideas aren’t necessarily the prettiest ones.

They need to make the space practical.

You should be able to open the door, immediately see what you have, and pull something out without having to remove half the cabinet first.

Start by Emptying the Entire Cabinet

I know this isn’t the most exciting part, but don’t skip it.

Before adding organizers, take absolutely everything out from underneath the sink.

Put everything on the counter or floor where you can see it.

This immediately makes it easier to see just how much you’ve accumulated.

You may discover:

Half-used cleaning products
Duplicate bottles
Old sponges
Extra garbage bags
Cleaning cloths
Dishwasher supplies
Brushes
Gloves
Products you never actually use
Empty or nearly empty containers

Don’t organize things simply because they’re already there.

If something is empty, expired, dried out, damaged, or something you haven’t used in years, this is the perfect time to get rid of it.

The goal isn’t to create a beautifully organized cabinet full of stuff.

The goal is to create a cabinet that’s easier to use.

Group Similar Items Together

Once everything is out, start creating simple categories.

You don’t need twenty different categories.

For a kitchen sink cabinet, I recommend keeping things grouped into a handful of practical sections.

Cleaning Products

Keep your everyday sprays and cleaning solutions together.

Dish washing Supplies

This can include dishwasher detergent, dish soap, rinse aid, brushes, and sponges.

Cleaning Tools

Keep scrub brushes, microfiber cloths, gloves, and reusable cleaning tools together.

Trash Supplies

Garbage bags, compost bags, and recycling bags can have their own section.

Refills

If you buy larger refill bottles or bulk cleaning products, keep them separate from the products you’re using every day.

This simple categorization makes a surprisingly big difference.

Instead of thinking, “Where did I put that?”

You know exactly which section to look in.

Use Stackable Bins to Create Levels

One of my favorite ways to organize an under sink cabinet is with stackable bins.

Because the cabinet is usually much taller than it is convenient to reach, you’re often wasting the vertical space.

A stackable organizer essentially creates another level.

You can keep frequently used products on the bottom and smaller supplies above them.

Clear bins are especially useful because you can see what’s inside without pulling everything out.

For example, you could have:

Top bin: sponges, scrubbers, and dishwasher accessories

Bottom bin: extra cleaning cloths and gloves

Or use one bin for daily cleaning products and another for refills.

The key is not to make the bins too deep.

If a container is packed so tightly that you have to dig through it every time you need something, you’ve simply created a prettier version of the same problem.

Add a Pull-Out Organizer

If you only make one upgrade to your under sink cabinet, I’d seriously consider a pull-out organizer.

The back of an under sink cabinet is one of those spaces that looks useful until you actually try to reach it.

You end up moving everything in front just to grab one bottle.

A sliding or pull-out organizer solves that problem.

Instead of reaching into the darkness at the back of the cabinet, you can simply pull the entire section toward you.

This works especially well for:

Spray bottles
Dish soap
Cleaning products
Sponges
Brushes
Dishwasher supplies

If your cabinet has plumbing running through the center, look for an organizer specifically designed around sink pipes rather than buying a standard drawer and hoping it fits.

Measure the cabinet first.

That’s important.

Make Use of the Cabinet Doors

The inside of the cabinet doors is valuable storage space that’s very easy to overlook.

A slim door-mounted organizer can hold smaller items that would otherwise take up valuable shelf space.

Think:

Sponges
Scrub brushes
Cleaning cloths
Gloves
Small brushes
Dishwasher tablets
Garbage bag rolls

I particularly like this idea for small items because it prevents them from getting lost underneath larger bottles.

Just be careful with the weight.

Before attaching anything to a cabinet door, check the organizer’s weight limit and make sure the door can comfortably support it.

Also check the clearance between the door and the plumbing or items stored inside.

Use a Small Lazy Susan for Bottles

A lazy Susan isn’t just for your pantry.

A small turntable can work surprisingly well underneath the sink, especially for bottles you use regularly.

Instead of reaching behind a row of cleaning products, you simply rotate the organizer until the bottle you need comes toward you.

This is particularly helpful for products that are used frequently.

I wouldn’t use a giant lazy Susan and fill it with every cleaning product you own, though.

A smaller one dedicated to your most-used bottles is usually much more practical.

Keep Everyday Products Easy to Reach

One of the biggest mistakes people make when organizing under the sink is putting everything away equally.

Not everything needs to be equally accessible.

Think about the products you reach for every day.

Dish soap.

Kitchen cleaner.

Sponges.

Dishwasher detergent.

Cleaning cloths.

Those should be the easiest things to grab.

Products you only use occasionally can go toward the back or higher up.

This creates a simple everyday zone and an occasional-use zone.

Once you start thinking this way, organizing becomes much easier.

Create a Dedicated Sponge and Scrubber Area

Sponges and scrubbers are tiny, but somehow they always manage to make an organized cabinet look messy.

Instead of throwing them into a bin with everything else, give them their own small container.

A shallow basket or small ventilated organizer works well.

If you store damp sponges underneath the sink, make sure they have an opportunity to dry properly rather than sitting in a sealed container.

A small ventilated holder is much more practical than a closed box.

I also like keeping replacement sponges separate from the one currently being used.

That way, you don’t accidentally pull out a fresh sponge every time you’re looking for the one at the sink.

Store Cleaning Cloths Vertically

Cleaning cloths have a habit of becoming one giant pile.

You pull one out and somehow five others come with it.

Instead of stacking them flat, fold them and store them vertically inside a small bin.

Think of it like organizing files in a filing cabinet.

You can see each cloth and pull out exactly the one you want.

This works especially well for microfiber cloths because they’re flexible and easy to fold.

You can also separate them by purpose if you have several types.

For example:

Kitchen cloths

Glass-cleaning cloths

General cleaning cloths

Keeping them separated means you’re not sorting through the entire pile every time you need one.

Don’t Ignore the Space Around the Plumbing

This is where a little creativity can make a huge difference.

The plumbing underneath your sink doesn’t have to mean that the space around it is wasted.

Instead of trying to force one large organizer into the cabinet, use smaller containers that can fit around the pipes.

You might have:

A narrow bin on one side
A pull-out organizer on the other
A small basket in front
Door storage for tiny items

The best setup will depend on your specific cabinet.

That’s why I recommend measuring first rather than buying organizers based on how they look online.

Use Narrow Bins for Awkward Spaces

Not every organizer needs to be wide.

Sometimes the narrow space beside a pipe is the perfect place for a slim bin.

These little gaps can hold:

Extra sponges
Cleaning brushes
Gloves
Small bottles
Dishwasher accessories
Replacement scrubbers

Rather than trying to make every inch look symmetrical, focus on making every usable inch functional.

That’s what actually makes an under sink cabinet easier to maintain.

Keep Garbage Bags Easy to Grab

If your garbage bags are still sitting inside their original cardboard box underneath the sink, there’s a simple upgrade you can make.

Place the roll inside a dispenser or dedicated container so you can pull out one bag at a time.

You can also use a narrow bin to store extra rolls vertically.

If you have separate bags for garbage, recycling, and compost, give each type its own section.

This prevents the dreaded situation where you pull everything out just to find the right size bag.

Add Labels, But Don’t Overdo It

Labels can make an organized cabinet even easier to maintain.

But you don’t need to label every single container.

I prefer broad labels such as:

DISHWASHING

CLEANING

SPONGES

REFILLS

GARBAGE BAGS

This is especially useful if several people in your household put things away.

The easier the system is to understand, the more likely everyone is to actually use it.

A Simple Under Sink Organization Layout

If you’re not sure where to begin, here’s a simple setup you can adapt to your cabinet.

Left Side

Place your most-used cleaning products in a pull-out organizer.

Center

Keep the area around the plumbing as open as possible.

Use smaller containers that work around the pipes instead of trying to cover them.

Right Side

Use a stackable bin for cleaning cloths, gloves, and scrubbers.

Cabinet Door

Store lightweight smaller items such as sponges, brushes, or dishwasher accessories.

Back of Cabinet

Reserve this area for refills and products you don’t use every day.

The exact arrangement will depend on your cabinet, but the basic principle stays the same:

Frequently used items in front.

Small items contained.

Rarely used items toward the back.

How to Organize Under the Bathroom Sink

The same principles work in the bathroom, but the categories will obviously be different.

Bathroom sink cabinets often become a dumping ground for toiletries, cleaning products, extra toilet paper, hair tools, and backup products.

Start by removing everything and grouping similar items.

Try creating sections for:

Hair products
Skincare
Toiletries
Cleaning supplies
Extra toilet paper
Towels
Backup products

Small clear bins work particularly well here because you can create separate categories without taking up much room.

For a shared bathroom, labels can also help everyone know where things belong.

The Biggest Under Sink Organization Mistakes

Even a beautiful storage system can become frustrating if the setup isn’t practical.

Buying Organizers Before Measuring

This is probably the easiest mistake to make.

That gorgeous organizer you’ve been eyeing might not fit around your plumbing.

Measure:

Cabinet width
Cabinet depth
Cabinet height
Door clearance
Distance around pipes
Any fixed shelves or supports

Then shop for organizers.

Using Containers That Are Too Deep

Deep bins look like they hold more, but they can become black holes.

If you have to remove five bottles to reach the back, the system isn’t helping.

Overfilling Every Container

Leave a little breathing room.

A bin that’s 100% full becomes difficult to use and difficult to maintain.

Keeping Too Many Backups

Buying household products in bulk can save money, but only if you actually have room to store them.

You don’t need twelve bottles of cleaner underneath the sink.

Keep a reasonable backup supply and store larger quantities somewhere else if necessary.

How to Keep Your Under Sink Cabinet Organized

The best organization system is one you can maintain.

You don’t need to completely reorganize the cabinet every month.

Instead, make a habit of doing a quick reset whenever you notice things getting messy.

Put bottles back in their designated section.

Throw away empty containers.

Replace supplies that have run out.

Wipe the cabinet if something spills.

And every few months, take everything out for a quick check.

It should only take a few minutes once you already have a system in place.

Final Thoughts

A messy under sink cabinet can make an otherwise tidy kitchen or bathroom feel unnecessarily chaotic.

But you don’t need a complete renovation to fix it.

A few well-chosen bins, a pull-out organizer, some door storage, and a little categorizing can completely change how the space works.

The biggest thing I’ve learned is that good under sink organization isn’t about fitting the most things into the cabinet. It’s about making the things you actually use easy to find and easy to put away.

Start by taking everything out.

Get rid of what you don’t need.

Group similar items together.

Measure your cabinet.

Then choose storage solutions that work around your plumbing rather than trying to fight it.

Once everything has a designated home, keeping the cabinet organized becomes so much easier.

And honestly, there’s something incredibly satisfying about opening that cabinet door and actually being able to see everything inside.

Your under sink cabinet doesn’t have to be the messy cabinet.

With a simple system, it can become one of the most useful storage spaces in your home.
