The cabinet under the sink is the worst-designed storage space in most homes, and it is not your fault. A pipe runs straight through the middle of it, the floor is uneven, items get damp, and the whole thing is too deep to reach the back of without kneeling and excavating. So it becomes a graveyard of half-empty spray bottles and sponges you forgot you owned. The right organizer works around the pipe instead of fighting it.
This guide compares the eight best under-sink organizers for 2026 across both kitchen and bathroom cabinets, from pull-out drawers that bring the back to you to expandable shelves that step around the P-trap. Each pick explains what it is, why it works in that awkward space, and who it suits. Every pick is evaluated Research-Backed and Spec Checked against published specifications and aggregated owner feedback; we do not make first-hand product testing claims.

1. BUKFEN 2-Tier Pull-Out Under-Sink Organizer - Best for Deep Cabinets
The single biggest under-sink problem is depth: the back two-thirds of the cabinet is technically storage but practically unreachable. A pull-out organizer fixes this by mounting sliding drawers that bring the whole back forward to you. The BUKFEN two-tier unit is built specifically for the under-sink shape, with a split design so each side clears the pipe and slides independently.
This is the upgrade that makes a deep cabinet usable in both kitchens and bathrooms. Load cleaning supplies, sponges, or backstock on the drawers, pull, take what you need, and slide it back without kneeling and digging. The two-tier height suits taller bottles below and shorter items above. It is the priciest format here, but it solves the access problem the others only ease.
Best for: Deep kitchen or bathroom cabinets where the back is impossible to reach without unloading the front.
Pros: Sliding drawers bring the back forward, split design clears the pipe, two tiers separate tall and short, sturdy build.
Cons: Highest cost here; needs assembly and enough cabinet width for both sides.
2. Rubbermaid Under-Sink Cabinet Organizer - Best Budget Shelf
If you want a no-fuss improvement for very little money, a simple stable shelf that sits around the pipe is the value pick. The Rubbermaid under-sink organizer adds a second level so you stop stacking bottles directly on the cabinet floor, which is the main reason under-sink cabinets feel cramped and tip-prone.
It will not slide out like a drawer, but it doubles your usable height for the price of a couple of coffees, and it works in both kitchen and bathroom cabinets. Put backstock and rarely-used items on the upper level and daily supplies below. For a first under-sink upgrade on a budget, this is the easiest place to start.
Best for: A cheap, fast first upgrade that adds a second level around the pipe.
Pros: Very affordable, stable two-level design, works in kitchen or bath, no assembly headache.
Cons: No pull-out access; fixed shape may not suit every pipe layout.
3. Expandable Under-Sink Shelf Organizer - Best for Working Around the P-Trap
The P-trap, that U-shaped pipe, is what defeats most rigid organizers. An expandable shelf is the answer because its width adjusts and its legs step around the pipe rather than running into it. The shelf surface usually has a cutout or split so the platform sits on both sides of the plumbing at once.
This is the most universally compatible format, which is why it is the safest pick if you are not sure your cabinet will fit a fixed unit. Adjust the width to your cabinet, set the height to clear the pipe, and you have a flat second level where there was only an awkward gap. It suits any cabinet with a centered or off-center pipe.
Best for: Cabinets where the pipe sits awkwardly and rigid organizers will not fit.
Pros: Adjustable width fits most cabinets, legs step around the pipe, creates a flat usable shelf, easy setup.
Cons: Less rigid than a fixed unit; heavy loads can flex a wide span.

4. 2-Tier Sliding Cabinet Basket Drawers - Best Mid-Range Pull-Out
Between the premium pull-out and the budget shelf sits the sliding basket drawer: wire or mesh baskets on glide rails that you mount to the cabinet floor or a shelf. They deliver most of the pull-out convenience for a lower price, and the open mesh lets any drips dry instead of pooling.
These suit cleaning supplies and sponges well because ventilation keeps damp items from getting musty. Mount one or two baskets to one side of the pipe and you get drawer-style access to the back without the cost of a full split system. They are a sensible middle ground for most kitchen cabinets.
Best for: Drawer-style access at a mid-range price, especially for damp-prone cleaning supplies.
Pros: Pull-out convenience for less, ventilated mesh dries drips, mounts to floor or shelf, mix-and-match baskets.
Cons: Mounting required; baskets do not contain very small loose items.

5. Under-Sink Cleaning Supply Caddy - Best for Carrying Supplies
Not everything under the sink should stay there. The supplies you carry from room to room, all-purpose spray, microfiber cloths, scrub brush, do better in a portable caddy you lift out whole. A divided caddy keeps a cleaning kit together so you grab one handle instead of gathering five items each time you clean.
Keeping a caddy on the cabinet floor also makes the rest of the space easier to organize, because the bulky bottles travel with you instead of crowding the shelves. It works equally well in kitchen and bathroom cabinets, and it is the cheapest way to turn a messy pile of bottles into a grab-and-go kit.
Best for: Anyone who carries cleaning supplies around the house and wants a grab-and-go kit.
Pros: Lifts out as a complete kit, divided sections sort bottles and brushes, frees the cabinet, low cost.
Cons: Holds less than fixed shelving; a caddy alone will not organize the whole cabinet.
6. Hanging Cabinet-Door Storage Basket Set - Best for the Cabinet Door
The inside of the cabinet door is free storage almost everyone ignores. A set of baskets that hang over the door or mount to it turns that flat panel into shallow shelves perfect for sponges, gloves, small bottles, and trash bags. Because the door storage sits in front of the pipe, it uses space that no shelf can reach.
This pick pairs well with any of the shelf or drawer options above: put daily small items on the door so they are visible the moment you open the cabinet, and keep backstock on the shelves behind. It is a small-spend, high-impact addition for both kitchen and bathroom sinks.
Best for: Adding shallow visible storage on the inside of the cabinet door.
Pros: Uses ignored door space, keeps small items visible, pairs with any shelf, no-drill over-door options exist.
Cons: Shallow capacity; door must clear the contents when closing.

7. Stackable Under-Sink Drawer Bins - Best for Small Items
Small items, sponges, scrubbers, dish tabs, extra toothbrushes, get lost and knocked over in an open cabinet. Stackable drawer bins corral them into a tidy tower of pull-out drawers that fits to one side of the pipe. Instead of a tipping pile, you get labeled compartments you can open one at a time.
This is the format that finally tames the loose-small-stuff problem in both kitchen and bathroom cabinets. Stack two or three drawers high to use the vertical space, and reserve the deeper bottom drawer for taller bottles. It is an inexpensive way to bring order to the clutter the bigger shelves do not solve.
Best for: Corralling sponges, tabs, and other small items that tip over in an open cabinet.
Pros: Pull-out drawers for small items, stacks to use vertical space, fits beside the pipe, low cost.
Cons: Plastic drawers feel less sturdy than wire; not for heavy bottles up high.

8. Under-Sink Spray Bottle Hanging Rod - Best for Clearing the Floor
Spray bottles are the worst offenders under the sink because they are tall, tip easily, and waste the floor space they stand on. A simple tension rod mounted across the cabinet lets you hang spray bottles by their trigger handles, lifting them off the floor entirely and freeing the whole base of the cabinet for bins or a caddy.
It is the cheapest and fastest under-sink fix on this list, often a single rod you wedge in place with no tools. Hang your sprays from it and suddenly there is a clear floor underneath for everything else. It works in any cabinet wide enough to span and pairs with every other pick here.
Best for: Lifting tippy spray bottles off the floor to reclaim the cabinet base.
Pros: Extremely cheap, no-tool tension install, frees the floor, pairs with any other organizer.
Cons: Only holds trigger-handle bottles; tension fit can slip if overloaded.

How to Choose an Under-Sink Organizer: The Method
Measure Around the Pipe First
Before buying anything, note where the pipe enters the cabinet and how much clear width and height sits on each side of it. The most common return is an organizer that does not fit around the plumbing. Expandable and split-design units are the safest when the pipe sits awkwardly center.
For daily-access supplies, choose pull-out drawers or sliding baskets so you never kneel and dig. For backstock you rarely touch, a fixed shelf is fine and cheaper. Most cabinets work best with a mix: a pull-out for daily items and a shelf above for spares.
Use the Door and the Floor, Not Just the Shelf
The inside of the door and a hanging rod for spray bottles add storage that no shelf can reach, because they use the space in front of and around the pipe. Capture those two spots before assuming the cabinet is full.
Plan for Moisture
Under-sink cabinets get damp from condensation and the occasional drip. Favor ventilated wire or mesh for items that can hold moisture, keep a thin liner or tray under the area near the pipe, and store anything paper-based up high rather than on the floor.
Frequently Asked Questions
What is the best type of under-sink organizer?
For most people a pull-out drawer or sliding basket is best, because the back of an under-sink cabinet is otherwise unreachable. If budget is tight, start with a simple two-level shelf that sits around the pipe, then add door baskets and a spray-bottle rod to capture the rest of the space.
How do I organize under the sink when a pipe is in the way?
Use an expandable shelf or a split two-sided pull-out designed to step around the P-trap, and add storage in the spots the pipe does not block: the inside of the door and a tension rod for hanging spray bottles. Measure the clear space on each side of the pipe before buying.
Can the same organizer work for kitchen and bathroom sinks?
Yes. Most under-sink organizers work in both, since the cabinets share the same pipe-in-the-middle problem. The difference is contents: kitchens hold cleaning supplies and dish items, bathrooms hold toiletries and backstock, but the shelves, drawers, and door baskets are the same.
How do I protect against leaks under the sink?
Keep paper goods off the cabinet floor, use ventilated organizers near the pipe so drips can dry, and consider a thin tray or liner under the plumbing area to catch slow drips. Check the connections periodically so a small leak does not ruin stored items.
The Bottom Line
The cabinet under the sink becomes usable the moment you stop storing on its floor and start working around the pipe. A BUKFEN pull-out or sliding baskets bring the unreachable back forward, an expandable shelf or budget Rubbermaid unit adds a second level around the plumbing, and a door basket set plus a spray-bottle rod capture the space no shelf can. Add a portable caddy so your cleaning kit travels with you.
