How to Organize Under the Sink: 12 Practical Storage Ideas That Actually Work

The cabinet under a sink looks like useful storage space—until you open the door and see pipes, cleaning bottles, extra supplies, and dozens of small items competing for the same awkward area.

The solution isn't simply adding more containers.

A useful under-sink organization system starts by working around the plumbing, keeping frequently used items accessible, and making sure the area can still be inspected when necessary.

Whether you're organizing a kitchen or bathroom cabinet, these practical ideas can help turn under-sink space into storage that's easier to use and maintain.

1. Empty the Cabinet Before Organizing It

Start by removing everything from the cabinet.

This gives you an opportunity to see what you're actually storing and inspect the space before adding organizers.

Group similar items together and remove empty containers, unnecessary duplicates, and anything that belongs somewhere else.

Don't put everything back simply because it was already there.

2. Check the Cabinet and Plumbing

Before installing storage products, look carefully at the pipes, disposal equipment if present, water lines, cabinet walls, hinges, and other hardware.

If you notice active moisture, leaking, significant water damage, or another plumbing concern, address the underlying problem rather than hiding it behind storage containers.

Organizers should not make important plumbing components impossible to inspect or access.

3. Measure Around the Pipes

Under-sink cabinets rarely provide one simple rectangular storage area.

Measure:

• Interior cabinet width
• Usable depth
• Available height
• Pipe locations
• Distance between plumbing components
• Door and hinge clearance
• Any disposal or filtration equipment

These measurements matter more than the cabinet's overall dimensions.

4. Create Storage Zones

Instead of treating the entire cabinet as one storage area, divide it into categories.

A kitchen under-sink cabinet might include:

• Everyday cleaning supplies
• Dishwashing supplies
• Cleaning cloths and sponges
• Trash or recycling supplies
• Backup household products

A bathroom cabinet might use different categories, such as personal-care backups, cleaning supplies, or other appropriate household items.

The exact categories should reflect what your household actually stores there.

5. Use Pull-Out Organizers for Deep Cabinets

Deep cabinets can make products toward the back difficult to reach.

A properly sized pull-out organizer or drawer can bring stored items forward instead of requiring you to reach around plumbing and other supplies.

Before purchasing one, confirm that the drawer or organizer can fully operate without colliding with pipes, hinges, or cabinet doors.

6. Use Vertical Space Carefully

Much of the area above short bottles and containers can go unused.

Depending on the cabinet layout, tiered organizers, stackable drawers, or appropriately designed shelving can make some of this vertical space useful.

But don't build a complicated structure that blocks plumbing or makes products difficult to retrieve.

Accessible storage is more valuable than maximizing every inch.

7. Use Bins to Contain Categories

Bins can help keep similar supplies together and make it easier to remove an entire category when necessary.

For example, one suitable bin might hold dishwasher-related supplies while another contains cleaning cloths.

Choose bin sizes based on the available cabinet space and the products you actually store.

8. Consider the Cabinet Doors

The inside of cabinet doors may provide additional storage opportunities when suitable organizers are compatible with the cabinet.

Before adding anything, check:

• Door thickness
• Handle and hinge clearance
• Whether stored items will collide with interior shelves or plumbing
• The organizer manufacturer's installation instructions

A door organizer is useful only if the cabinet can still close normally.

9. Keep Frequently Used Items in Front

Everyday supplies should generally be easier to reach than backup items.

If you use something regularly, don't bury it behind products that are opened once every few months.

Place less frequently used appropriate supplies toward secondary areas while keeping your everyday categories accessible.

10. Don't Overfill the Cabinet

Under-sink cabinets can become cluttered again quickly when every available space is filled.

Leaving some open space makes items easier to remove and gives you better visibility around the plumbing.

If the cabinet is already full immediately after organizing, reconsider whether everything stored there actually needs to remain under the sink.

11. Be Careful With Household Chemicals

Household cleaning products should be stored according to their labels and manufacturer instructions.

Do not combine chemicals or transfer products into inappropriate unlabeled containers.

If children or pets are present, consider whether the storage location and cabinet access are appropriate for the products being stored.

Some products may require a different or secured storage location.

12. Make the System Easy to Reset

A complicated organization system is difficult to maintain.

Ideally, every commonly used item should have an obvious place where it can be returned in seconds.

Simple categories and appropriately sized organizers usually work better than a cabinet filled with many tiny compartments.

Kitchen vs Bathroom Under-Sink Organization

The same basic principles work in both rooms, but the contents can be very different.

Kitchen under-sink storage often needs to accommodate cleaning and dishwashing supplies around substantial plumbing or other equipment.

Bathroom under-sink storage may involve smaller personal-care and household items along with plumbing.

Choose organizers based on the specific cabinet rather than assuming the same setup will work everywhere.

Under-Sink Drawers vs Storage Bins

Both can be useful.

Pull-out drawers can improve access to deeper storage areas.

Storage bins make it easy to group and remove categories of supplies.

In some cabinets, combining the two approaches can work well—as long as the arrangement fits safely around plumbing and other hardware.

Common Under-Sink Organization Mistakes

• Buying organizers before measuring around the plumbing
• Ignoring leaks or moisture
• Blocking access to pipes and plumbing components
• Trying to fill every inch of the cabinet
• Using drawers that cannot fully open
• Keeping too many duplicate products
• Mixing unrelated categories together
• Storing household chemicals without considering label instructions and household safety
• Creating a system that's too complicated to maintain

A Simple Under-Sink Organization Checklist

• Measure around pipes and hardware
• Remove unnecessary items
• Create clear storage categories
• Choose organizers that fit the usable space
• Keep frequently used items accessible
