The cabinet under the sink is one of those spaces that looks generous until you actually try to use it. Pipes interrupt the middle, cleaning bottles compete for height, small items disappear at the back, and a deep cabinet can quickly turn into a place where things are stored rather than organized.
A good under sink organizer solves a very specific problem: it helps you use vertical and horizontal space without making everyday items harder to reach. For a small kitchen or bathroom, that can mean the difference between a cluttered cabinet and storage that actually works.
Below, I compared five practical under sink storage options with different layouts, from L-shaped organizers designed around plumbing to clear drawers for smaller bathroom essentials. Rather than choosing one style for everyone, the goal is to match the organizer to the cabinet you already have.
Best Overall Pick for Awkward Plumbing
REALINN L-Shaped Under Sink Organizer
The L-shaped layout leaves room around plumbing while creating two usable storage levels, making it the most purpose-built option in this roundup for difficult sink cabinets.

1. REALINN L-Shaped Under Sink Organizer — Best for Plumbing
If plumbing is the reason your cabinet never feels organized, an L-shaped organizer is one of the most logical designs to consider. The REALINN L-Shaped Under Sink Organizer is designed to leave more open space around pipes while still creating two useful storage levels.
The layout makes it particularly suitable for a small kitchen under sink organization project where a conventional full-width shelf would collide with plumbing. The lower tier pulls out, which also helps with one of the biggest problems in a deep cabinet: reaching bottles at the back.
Best for: awkward plumbing, deep sink cabinets and households that store cleaning bottles under the sink.
Why it stands out: the L-shaped structure is more purpose-built for sink cabinets than a generic rectangular shelf.
Consider before buying: pipe positions vary widely. Measure the usable side-to-side space and check where the upper shelf would sit in relation to your plumbing.

2. Kitstorack 2-Tier Under Sink Organizer — Best All-Purpose Option
The Kitstorack 2-Tier Under Sink Organizer is a more straightforward choice for anyone who wants to add vertical storage without turning the cabinet into a complicated system. Two tiers separate taller bottles, sprays, sponges and smaller household essentials so you can see more of what you already own.
This type of organizer works especially well for cleaning supplies organization. Instead of lining bottles in several rows, you can divide them by use: everyday cleaners on the easiest-to-reach level and backups or less frequently used items above or behind them.
Best for: simple kitchen cabinet organization, bathroom cleaning supplies and renters who want a removable storage solution.
Why it stands out: the two-tier format is easy to understand and can create more usable storage without permanent cabinet modifications.
Consider before buying: check the clearance beneath the sink basin and make sure the shelves will not interfere with cabinet doors or plumbing.
3. Delamu 2-Tier Pull-Out Cabinet Shelf — Best for Adjustable Storage
A fixed shelf is not always ideal when the products you store vary in height. The Delamu 2-Tier Pull-Out Cabinet Shelf is worth considering when adjustability matters, particularly if your under-sink area contains a mix of tall spray bottles, shorter containers and refill products.
The pull-out format is useful for under kitchen sink organization because it reduces the need to reach through the front row to find something at the back. In a deep cabinet, that small change can make the space much easier to maintain over time.
Best for: deep cabinets, mixed-height supplies and people who prefer pull-out access.
Why it stands out: adjustable shelf positioning gives you more flexibility than a one-height-fits-all rack.
Consider before buying: measure both cabinet depth and vertical clearance. Adjustable organizers still need enough unobstructed room to slide properly.
4. Delamu Clear 2-Tier Organizer — Best for Bathroom Under Sink Organization
Not every sink cabinet is filled with large cleaning products. In a bathroom, the challenge is often a collection of smaller items: skincare, hair products, first-aid supplies, extra toiletries and cleaning essentials. A clear organizer can make that kind of storage easier to scan.
The Delamu Clear 2-Tier Organizer combines transparent storage with a divided layout, making it a practical option for small bathroom organization and vanity storage. Clear sides help you see what is inside without pulling every container forward.
Best for: bathrooms, skincare, beauty products and small household essentials.
Why it stands out: visual access. Clear storage is especially useful when you have several similar containers and want to reduce forgotten duplicates.
Consider before buying: transparent organizers look best when categories stay fairly simple. If every drawer becomes a mixed catch-all, visibility alone will not solve the clutter.
5. Vtopmart Stackable Storage Drawers — Best for Small Essentials
Sometimes the best under sink storage idea is not a traditional open shelf at all. If you need to organize small items rather than tall bottles, drawer-style storage can prevent loose products from spreading across the cabinet floor.
The Vtopmart Stackable Storage Drawers can work well in bathroom vanities, side cabinets or other areas where plumbing leaves a usable rectangular pocket. The drawer format is particularly useful for items such as sponges, dishwasher supplies, cloths, beauty products or backups that would otherwise be stacked loosely.
Best for: small bathroom storage, vanities, side sections of sink cabinets and smaller household items.
Why it stands out: drawers keep categories contained and make smaller items easier to retrieve.
Consider before buying: this style needs enough straight, unobstructed space for the drawer to open. It may not be the best choice directly beneath complicated plumbing.
How to Choose an Under Sink Organizer
1. Measure the Cabinet, Not Just the Door Opening
For successful under sink organization, measure the usable interior width, depth and height. Then measure again around anything that reduces that space: pipes, a garbage disposal, filters, hinges and the sink basin itself.
2. Decide What You Actually Store There
A rack designed for tall cleaning bottles solves a different problem from clear drawers intended for skincare or dishwasher pods. Before buying an organizer, empty the cabinet and group its contents. This makes it much easier to choose between pull-out shelves, two-tier storage and drawer organizers.
3. Prioritize Easy Access in Deep Cabinets
A deep cabinet creates storage capacity but can also hide products. Pull-out organizers are useful because they bring the back of the cabinet forward. If you regularly forget what is behind the first row of bottles, this may matter more than maximizing the total number of shelves.
4. Leave Space Around Plumbing
Do not build such a tight storage system that basic plumbing becomes inaccessible. An L-shaped organizer or a pair of narrower units can sometimes be better than one large shelf. This is particularly important in small kitchen organization, where every inch matters but maintenance access still needs to remain practical.
5. Think About Cleaning
The under-sink cabinet is more exposed to drips and leaks than most storage areas. Look for materials and layouts that are easy to wipe down, and avoid packing the cabinet so tightly that you cannot see the floor beneath the pipes.
A Simple Under Sink Organization Plan
If you want to reorganize the space in one afternoon, keep the process simple:
- Empty the cabinet completely. Throw away expired or empty products.
- Group items by use. Keep daily cleaners, backups, sponges and specialty products together.
- Measure around the plumbing. Note the exact locations where shelving cannot go.
- Choose one primary organizer. Avoid buying several containers before you know how the main unit fits.
- Place frequently used products at the front. The best storage system is one you can maintain without rearranging it every week.
This approach also works for bathroom under sink organization, where toiletries and personal-care products often accumulate in the same way cleaning supplies do in the kitchen.
Which Under Sink Organizer Is Best?
For cabinets where plumbing is the main obstacle, the REALINN L-Shaped Under Sink Organizer is the most purpose-specific option in this list. If you simply want a versatile two-level system for cleaning supplies, the Kitstorack 2-Tier Organizer is the more straightforward choice.
For deeper cabinets, a pull-out option such as the Delamu 2-Tier Pull-Out Cabinet Shelf can make items at the back easier to reach. In bathrooms, the clear Delamu organizer and Vtopmart drawers offer a different advantage: keeping smaller items visible and contained.
The right answer depends less on which organizer looks best online and more on the shape of your cabinet. Measure first, decide what needs to be stored, and choose the design that solves that exact problem.
Frequently Asked Questions
What is the best way to organize under a kitchen sink?
Start by removing everything and grouping cleaning supplies by use. Measure around pipes and the garbage disposal, then use vertical storage such as a two-tier or L-shaped under sink organizer. Keep frequently used products easy to reach and avoid blocking plumbing access.
Are pull-out under sink organizers worth it?
They can be especially useful in deep cabinets because they bring items from the back of the cabinet forward. They are less important in very shallow cabinets where everything is already visible.
How do I organize under the sink when pipes are in the way?
Look for L-shaped or narrow organizers that leave open space around the plumbing. Measure pipe placement before purchasing; two smaller organizers may sometimes fit better than one wide unit.
What should not be stored under the kitchen sink?
Avoid using the area for items that could be damaged by moisture or an unexpected leak. Food, paper goods and other moisture-sensitive products are usually better stored elsewhere. Follow the storage instructions on household chemicals and keep hazardous products safely away from children and pets.
How can I organize a small bathroom under the sink?
Use vertical space and divide products into categories. Clear drawers or compact two-tier organizers work well for toiletries, skincare and backup products because smaller items are easier to see and contain.
Final Thoughts
A well-planned under sink organizer does not need to fill every inch of the cabinet. The goal is to create a storage system that makes everyday products visible, accessible and easy to put back. For a small kitchen or bathroom, a few inches of well-used vertical space can make a surprisingly large difference.
Before choosing any of these organizers, check the current product details on Amazon and compare them with your cabinet measurements. A five-minute measuring job is far easier than trying to make the wrong organizer fit around a pipe.
