The short answer
The best under-sink organizer for kitchen cabinets is the Delamu 2-Tier Under-Sink Organizer Set: two pull-out drawer units that fit around your pipes, adjust to five heights, and need no tools, no screws, and no landlord permission. If your cabinet is narrow, the SimpleHouseware 2-Tier Sliding Basket Drawer is the pick — an 8-inch-wide stackable basket that slides out like a drawer and is rated 4.5 stars from more than 28,000 Amazon ratings. That is the whole list. Only two no-drill organizers cleared our 4.5-star bar, and we would rather give you two honest picks than five padded ones — the section on what we skipped explains exactly why the famous names didn’t make it.

Every product on TinyCounter has to clear the same three bars: an established Amazon listing that has been selling for a long time, a rating of 4.5 stars or higher, and high sales volume — thousands of ratings or strong recent sales. We apply that bar to every category, and in most categories five or six products clear it. Under-sink organizers are the exception.
This category is dominated by near-misses. The REALINN 2-pack has sold more than 10,000 units in a single month and has 4,800 ratings — but it sits at 4.4 stars. The SimpleHouseware expandable rack, the single most-reviewed under-sink organizer on Amazon with nearly 20,000 ratings, also sits at 4.4 stars. SPACEKEEPER, NETEL, and Ceetug all land between 4.3 and 4.4. A 4.4-star product with 20,000 reviews is not a bad product — but our rule is the rule, and lowering it quietly for one category would make the bar meaningless everywhere else. So this guide has two picks, both genuinely 4.5 stars or better, and a full account of everything we left out and why. If a third organizer clears 4.5 stars with real volume, we will add it and update this page.
We also filtered for the promise in the title: no-drill. Every pick here is free-standing or snap-together — nothing screws into your cabinet, so renters can use them and take them along when they move. The one serious screw-mount option, the LYNK Professional pull-out, is covered in the skipped section for homeowners who don’t mind drilling.
1. Delamu 2-Tier Under-Sink Organizer Set (2-pack) — best overall
Key specs: 2 organizers per set · 2-tier pull-out drawers · 5 height options from 13.8″ to 17.8″ · L-shaped design fits around plumbing · wood handles · snap-together assembly, no tools · 4.5★, 3,000+ bought in the past month
The cabinet under the sink is the most wasted space in a small kitchen: pipes eat the middle, so everything becomes a pile of bottles you have to kneel and dig through. Delamu’s fix is a two-tier pull-out drawer with an L-shaped frame that works around the drain and P-trap instead of fighting them. The drawers slide out to bring the back row to you, and five height settings (13.8 to 17.8 inches) let you fit tall detergent bottles on one side and sponges and trash bags on the other. You get two organizers in the set — one a little over 9 inches tall, the other about a foot — so both sides of a wide under-sink cabinet get covered, or the second one goes under the bathroom sink. Reviewers keep coming back to the same two points: assembly takes about five minutes with no tools, and the pull-out shelves glide smoothly even when loaded with full bottles.
Why it fits a small kitchen: it converts the single most awkward cabinet in the apartment into real, reachable storage — with no drilling, no screws, and no landlord permission needed. It is also the pick we recommend in our best kitchen organization ideas for small apartments, because it solves the worst zone in the kitchen in one box.
Best for: renters and anyone whose cleaning supplies currently live in a heap under the sink.
Skip if: your under-sink cabinet is unusually shallow or your plumbing sits very low — measure the height under your pipes first, and check the 13.8-inch minimum height.
Pros
- ✓ Pull-out drawers bring the back row to you — no more kneeling and digging
- ✓ L-shaped design fits around pipes and P-traps instead of wasting that space
- ✓ Five height settings (13.8″–17.8″) adapt to tall bottles and odd plumbing
- ✓ Two organizers per set cover a wide cabinet or a second sink
- ✓ Strong recent demand: 3,000+ bought in the past month
Cons
- ✗ The L-shape means one tier is narrower than the other — very wide bottles may not fit the slim side
- ✗ Drawers can tip forward if you pull them out too far while fully loaded
- ✗ You must measure first — a few buyers found their cabinet too short or their pipes in the way
2. SimpleHouseware 2-Tier Sliding Basket Drawer — best for narrow cabinets
Key specs: 14″ D × 8″ W × 12.75″ H · 2 sliding wire basket drawers · drawer 6.75″ W × 3.8″ H · stackable — buy two and stack them · free-standing, no mounting or drilling · 4.5★ from 28,000+ Amazon ratings
Not every under-sink cabinet is wide. In older apartments and galley kitchens the cabinet can be barely wider than the sink itself, and a two-unit set like the Delamu simply won’t fit side by side. That is the job for SimpleHouseware’s sliding basket drawer: at just 8 inches wide it slides into the narrow gap beside the pipes, and its two wire baskets pull out like drawers so you can reach the spray bottles at the back without moving everything in front. Buy a second one and they stack, which turns one narrow column into a four-basket tower. Nothing mounts or screws in — it stands on the cabinet floor — so it is as renter-safe as the Delamu, and with more than 28,000 ratings behind it, it has the deepest review history of any pick in this guide.
Why it fits a small kitchen: the slim 8-inch width fits cabinets the wider organizers can’t, the stackable design doubles storage vertically, and the pull-out baskets fix the same reach problem as a full pull-out shelf at a fraction of the footprint.
Best for: narrow under-sink cabinets, galley kitchens, and anyone who wants to stack two units into a tall storage column.
Skip if: you store mostly wide items — at 8 inches wide with a 6.75-inch drawer, large detergent jugs and bulk bottles won’t fit; measure your biggest bottle first.
Pros
- ✓ 4.5★ from 28,000+ ratings — the deepest review history in this guide
- ✓ Just 8 inches wide — fits narrow cabinets other organizers can’t
- ✓ Baskets slide out like drawers, so the back row is reachable
- ✓ Stackable: two units become a four-basket tower with no hardware
- ✓ Free-standing — no drilling, no screws, no mounting of any kind
Cons
- ✗ Narrow drawers won’t take wide detergent jugs or bulk-size bottles
- ✗ Open wire baskets let very small items (caps, pods, single sponges) slip through or tip
- ✗ The wire-and-chrome look is practical, not pretty — it is a utility piece
How to measure under your sink before you buy
Most under-sink organizer returns happen for one reason: it didn’t fit. Pipes, disposals, and hinges make every cabinet different, so measure before you order — it takes two minutes and saves a return.
1. Measure the interior width and depth. Measure wall to wall inside the cabinet, not the door opening. Subtract an inch for the door hinges and any shelf lip. Your organizer must be narrower than that number.
2. Measure the height under the lowest pipe. Run a tape from the cabinet floor to the underside of the P-trap or drain pipe. That is your maximum organizer height — the Delamu needs at least 13.8 inches at its lowest setting, and the SimpleHouseware basket needs 12.75 inches. If your pipes hang lower than that, neither pick will fit, and no pull-out organizer will either.
3. Map the pipes. Note where the drain and supply lines run and how far they stick out from the back wall. An L-shaped organizer like the Delamu is designed to wrap around them; a rectangular basket like the SimpleHouseware needs a clear run of floor beside them.
4. Check the garbage disposal. If you have one, it steals a large block of space on one side and usually hangs low. Measure around it, not over it — and keep anything you store clear of its vibration.
5. Check the door swing. A pull-out drawer needs clearance to slide toward you. Make sure the cabinet door opens fully and nothing mounted on the door (a spice rack, a towel bar) blocks the drawer path.
What we skipped — and why
Honest guides say what they left out. These are the popular under-sink organizers that did not make the list, and the exact reason for each:
- REALINN 2-pack pull-out organizer (4.4★, 4,800+ ratings): the best-selling under-sink organizer on Amazon by volume — it has sold more than 10,000 units in a single month. But 4.4 stars is below our 4.5 bar, and buyers are split on the slide smoothness and size. Closest near-miss in the category.
- SimpleHouseware 2-tier expandable rack (4.4★, 19,800+ ratings): the most-reviewed under-sink organizer on Amazon, and genuinely clever — it expands from 15.75 to 25 inches wide with removable panels that work around pipes. It fails only on the rating bar, at 4.4 stars. If its rating ever crosses 4.5, it belongs in this guide.
- SPACEKEEPER sliding basket organizer (4.4★, 1,600+ ratings): a solid sliding-basket design with hooks and dividers, but 4.4 stars and a smaller review base than our picks.
- NETEL adjustable under-sink organizer (4.4★): flexible length and height with removable panels, and well-liked by buyers — but again 4.4 stars.
- Ceetug under-sink organizer (4.3★): popular and cheap, with a clever L-shape and a 55 lb capacity claim, but 4.3 stars is too far under our bar.
- LYNK Professional pull-out under-sink organizer (2,036+ ratings): the best-built option in the category — chrome-plated steel, ball-bearing glides, lifetime warranty, and reviewers with big disposals say it is the only one that fit. It is not in this guide for one reason: it screws into the cabinet floor. Homeowners who don’t mind drilling should look at it first; renters should stick with the two picks above.
- YouCopia RollOut Caddy 8″: a well-known rolling caddy (on Amazon since 2020, holds 30 lbs, no assembly) that we could not verify at 4.5 stars or higher in our check, so we did not list it as a pick. We will re-check it on our next review of this guide.
Buying guide: no-drill rules for renters
- Free-standing beats mounted, every time, if you rent. Pull-out drawers, stackable baskets, and rolling caddies all work without a single screw. Anything that drills into the cabinet floor or walls is a negotiation with your landlord — and a repair bill when you move out.
- Height is the number that matters. Under-sink cabinets are limited by pipes, not by width. Always measure floor-to-pipe before you buy, and buy the organizer that fits under your lowest pipe with room to spare.
- Two small beats one big. Two narrow organizers — one on each side of the pipes — almost always store more than one wide unit that has to dodge the plumbing. That is why our top pick comes as a two-pack.
- Keep only the weekly stuff under the sink. Cleaning sprays you use every week, sponges, trash bags, and a small caddy. Everything else — bulk refills, seasonal items, tools — belongs in a closet or on a higher shelf, not in the hardest cabinet to reach.
- Spills happen — plan for them. A pull-out drawer with a solid base contains a leaking bottle; an open wire basket does not. If you store detergents under the sink, put a cheap tray or a cut-to-size shelf liner underneath.
- Leave the pipes alone. Never rest an organizer against a supply line or hang weight from a drain pipe. Vibration and pressure cause leaks, and a leak inside a packed cabinet is discovered weeks too late.
Frequently asked questions
What is the best under-sink organizer for a small kitchen?
The Delamu 2-Tier Under-Sink Organizer Set: two pull-out drawer units that fit around pipes, adjust to five heights, and install with no tools. For narrow cabinets under about 10 inches wide, the SimpleHouseware sliding basket drawer is the better fit.
Do under-sink organizers need to be screwed in?
No — both picks in this guide are free-standing. Screw-mounted pull-outs like the LYNK Professional exist and are sturdier, but they require drilling into the cabinet floor, which most renters should avoid.
How do I organize under the kitchen sink if I have a garbage disposal?
Measure around the disposal first — it takes a large block of space and hangs low. Use an L-shaped organizer like the Delamu on the side opposite the disposal, or a slim basket like the SimpleHouseware in the remaining gap. Keep everything clear of the disposal’s vibration.
What should I keep under the kitchen sink?
Only cleaning supplies you use weekly, sponges, trash bags, and a small caddy. Never store food, heavy tools, or anything you need to dig for. Bulk refills belong in a closet.
Why do under-sink organizers have such low ratings?
Because fit is everything in this category and every cabinet is different. Most one-star reviews say “it didn’t fit my cabinet” — which is why this guide spends a whole section on measuring. Measure first, and the two picks here work as advertised.
Can I use these organizers in a bathroom cabinet too?
Yes. Both picks work under bathroom sinks as well — the Delamu two-pack is often split between the kitchen and a bathroom, and the SimpleHouseware basket fits narrow vanity cabinets.
The verdict
The under-sink cabinet is the hardest space in a small kitchen, and the honest answer is that only two no-drill organizers currently earn a recommendation from us. Buy the Delamu 2-Tier Under-Sink Organizer Set if your cabinet is standard width — it is the best overall fix, it comes as a two-pack, and it needs no tools. Buy the SimpleHouseware Sliding Basket Drawer if your cabinet is narrow or you want to stack two units into a tall column. Either way, measure floor-to-pipe before you order — that one measurement is the difference between an organizer that transforms the cabinet and a return label.
