Short answer: for most kitchen sinks, the Simple Houseware 2-Tier Sliding Cabinet Basket Organizer is the easiest win: two pull-out baskets that bring cleaning supplies to you. If a garbage disposal or pipes take up the middle of the cabinet, an L-shaped pull-out like the REALINN Under Sink Organizer fits around them. For a wide cabinet you want to fill edge to edge, choose an expandable under-sink shelf with removable panels.
Here are five picks for kitchen and bathroom sinks, and how to measure around your plumbing so the organizer actually fits.

The 5 best under-sink organizers in 2026
1. Simple Houseware 2-Tier Sliding Cabinet Basket Organizer: Best overall
This is one of the most-reviewed under-sink organizers on Amazon, and it is popular for a simple reason: two baskets slide out on rails, so bottles at the back come to the front. It fits beside the pipes in most standard sink cabinets.
Good to know
- Pull-out baskets end the reach-and-knock-over problem
- Two tiers double the usable space
- Also works in pantry and bathroom cabinets
Drawbacks
- Check height under the sink before buying
- Rails need occasional wiping to keep sliding smoothly
Skip it if: your plumbing fills the space where a rectangular unit would sit.
2. REALINN L-Shaped Under Sink Organizer: Best around pipes and disposals
Garbage disposals and drain pipes make rectangular organizers useless. This L-shaped pull-out wraps around the obstruction, so you can still use the space beside and in front of the pipes.
Good to know
- Designed specifically for awkward plumbing
- Pull-out shelf for easy access
- Metal frame for heavier bottles
Drawbacks
- Measure carefully: the L shape needs the right orientation
- Assembly takes a little longer than basic units
Skip it if: your cabinet has a clear, open space with no disposal.
3. Simple Houseware Expandable Under Sink Organizer: Best for wide cabinets
An expandable shelf stretches across the whole cabinet and lets you remove shelf panels where pipes come through. It turns one tall, empty space into two usable levels.
Good to know
- Adjusts to many cabinet widths
- Removable panels make room for pipes
- Creates two levels of storage
Drawbacks
- Items at the back are harder to reach than with pull-outs
- Works best with lighter items on the top shelf
Skip it if: you mainly want pull-out access.
4. madesmart 2-Tier Organizer: Best for small bottles
Bathroom sinks and small kitchen sinks fill up with little bottles that tip over. This two-tier organizer uses removable bins with adjustable dividers to keep small items upright and grouped, and it goes together in minutes.
Good to know
- Dividers stop small bottles from tipping
- See-through plastic shows what is inside
- Quick assembly, BPA-free plastic
Drawbacks
- Not for tall spray bottles on the lower tier
- Smaller footprint than shelf units
Skip it if: you mostly store tall bottles and large refills.
5. YouCopia Roll Out Caddy: Best caddy for cleaning supplies
Sometimes the simplest fix is best: a narrow rolling bin with a handle that pulls out like a drawer. Keep it under the sink for sprays and sponges, or carry the whole caddy to the room you are cleaning.
Good to know
- Slides out and lifts out with one hand
- Narrow enough to fit beside most pipes
- Doubles as a portable cleaning kit
Drawbacks
- Single level, so it holds less than a 2-tier unit
- Best for lighter items
Skip it if: you want to fill the whole cabinet.
How to choose an under-sink organizer
1. Map your plumbing
Open the cabinet and measure the clear space on each side of the pipes and disposal, the height to the lowest pipe, and the depth from the door to the back wall. Most fit problems come from skipping this step.
2. Pick the style for your layout
- Clear space on both sides of the pipes: two narrow sliding organizers, one on each side.
- Disposal in the middle: an L-shaped or U-shaped pull-out.
- Tall, wide cabinet: an expandable shelf with removable panels.
3. Think about moisture
Under-sink cabinets can get damp. Plastic and coated metal hold up better than bare wood or bamboo. A waterproof cabinet liner underneath protects the base if anything leaks.
Keep it organized
- Store only what you use at the sink: dish soap, sponges, cleaners and trash bags.
- Keep chemicals in a closed caddy and use child-safety latches if you have young children.
- Check for drips every few months so a slow leak does not damage the cabinet.
Frequently asked questions
How do I organize under the sink with a garbage disposal?
Use an L-shaped or U-shaped pull-out organizer, or place two narrow organizers on either side of the disposal. Measure the clear width on each side first.
What is the best material for under-sink organizers?
Plastic and coated metal are best because they resist moisture. Avoid untreated wood under sinks where drips are common.
Will an under-sink organizer fit a bathroom vanity?
Usually yes. Bathroom cabinets are often smaller, so measure the height and width around the drain, and look for compact two-tier organizers.
Do pull-out under-sink organizers need to be installed?
Many are freestanding and need no screws. Some heavier pull-outs can be screwed to the cabinet floor for extra stability.
