Cleaning supplies are the reason under sink cabinets get ugly. Bottles are different heights, sprays tip over, and the brush you want is always behind the one you don't. The right storage depends less on your cabinet and more on what you own, so start there.
If it's mostly spray bottles
Sprays are tall and top-heavy, which means they need floor space and a wall behind them — not a shelf that cuts the cabinet in half. Keep the cabinet floor open on one side of the pipe for sprays standing upright, and put the shelf on the other side. A height-adjustable shelf lets you set that clearance to the tallest bottle you own instead of guessing.
If it's sponges, gloves, and cloths
Small soft items disappear in deep bins. They belong on the inside of the door where you can see all of them at once. The no-drill door back hanger ($23) hooks over a standard cabinet door and gives you two shallow tiers — no screws, no damage, which matters if you rent.
If it's a bucket, brushes, and refill jugs
Bulky items are why fixed shelving fails. You need something you can pull toward you, because reaching over a pipe into the back of a 20-inch-deep cabinet is how things get abandoned. The SinkFlex Pull-Out Organizer ($33 for two) slides out on its own base, so the back of the cabinet stays reachable.
If it's all of the above
Most kitchens are the "all of the above" case, and buying one piece at a time is how you end up with mismatched racks that don't share the same height. The 3-Piece Under Sink Bundle ($55) is the shortcut: expandable shelving, slide-out baskets, and a caddy for the handful of things you carry room to room.
One rule that beats any product
Everything under the sink should be something you use in that room. Furniture polish, car wax, and the second vacuum attachment go somewhere else. Once the cabinet only holds kitchen cleaning gear, it stops overflowing.
Wet sponges are the other half of that. A sponge or a dish mat left sitting in a closed cabinet is one of the four things that make under sink cabinets smell musty — the other three are here, and a drain-through mat that empties into the sink solves most of the sponge half.
The clearance numbers that decide it
Product pages list widths and heights, but the number that actually kills an under sink setup is the gap between the lowest point of your plumbing and the cabinet floor. Measure that one number first — it rules out most options before you look at anything else. OkaNest's units happen to sit at three clear heights, so the call is easy:
| Clearance you measured | Door Back Hanger (12.2 in tall) | Pot & Lid Organizer, 1-Tier (15 in) | Pot & Lid Organizer, 2-Tier (19.1 in) |
|---|---|---|---|
| Under 12.2 in | No | No | No |
| 12.2 to 15 in | Yes | No | No |
| 15 to 19.1 in | Yes | Yes | No |
| 19.1 in and up | Yes | Yes | Yes |
Then check width, because the two floor-standing organizers have hard stops at opposite ends of the range:
| Cabinet inner width | Door Back Hanger | SinkFlex Pull-Out (30–36 in) | Pot & Lid Organizer (20.9–34.6 in) |
|---|---|---|---|
| 20.9 to 30 in | Yes | No, too narrow | Yes |
| 30 to 34.6 in | Yes | Yes | Yes |
| 34.6 to 36 in | Yes | Yes | No, too wide |
| Over 36 in | Yes | No, too wide | No, too wide |
The door back hanger ignores cabinet width completely — it hangs on the door, so it stays available in every row above. That is why it is the safe first buy when your cabinet is an odd size, and why the 2-tier pot organizer carries a 110 lb load rating while the hanger is meant for light items only.
Door depth: the measurement neither table above uses
Both tables above turn on height and width. The number they skip is depth, and for anything that hangs on the door it is the one that decides whether the door still shuts. The 2-tier door back hanger is 14.2 in wide and 12.2 in tall, but it stands 7.5 in off the door in the small size and 9.8 in in the large. That depth sits inside the cabinet and swings with the door.
Measure it with the door closed: run the tape from the inside face of the shut door straight back to whatever the hanger would hit first — the P-trap, the disposal body, or the back wall. That number is your clear depth, and it picks the size for you:
| Clear depth behind the shut door | Small hanger (7.5 in deep) | Large hanger (9.8 in deep) |
|---|---|---|
| Under 7.5 in | No | No |
| 7.5 to 9.8 in | Yes | No |
| 9.8 in and up | Yes | Yes |
If you come in under 7.5 in, door storage is out — put the floor-standing pot organizer in instead and leave the door empty. One honest note: we publish no load rating on the hanger, so keep it to light things (sprays, brushes, cloths). The 110 lb rating belongs to the pot organizer’s steel base, not to a hook on a cabinet door.
How many bottles actually fit on one tier
Storage photos are styled. The bottles in them were chosen because they fit. Here is the same math run on the bottles people actually keep under a sink, using the sizes printed on the packaging, against a 14.2 in wide tier.
| What you own | Real size | Across a 14.2 in tier | Fits a 12.2 in two-tier door frame |
|---|---|---|---|
| Quart trigger sprayer, 32 oz | 9.5 in tall, 3.25 to 3.5 in across | 4 | No. Bottle plus trigger is about 11 in, and two of them need 22 in of frame. |
| Refill jug, 64 oz | About 10.5 in tall, 4.5 in across | 3 | No. Taller than half the frame. |
| Gallon jug, bleach or floor cleaner | 11.5 to 11.8 in tall, 5.5 to 6.25 in across | 2 | No. Taller than a tier and heavier than a door wants. |
| Dish soap, 18 oz | About 8 in tall, 2.6 in across | 5 | Only if the basket clears 8 in. Measure it, do not assume. |
| Scouring powder canister, 12 oz | About 4 in tall, 3.3 in across | 4 | Yes |
| Dishwasher pod tub | About 9 in tall, 7 in across | 2 | No, unless the basket is a deep one. |
The counts are the width divided by the bottle width, with no gap left for fingers. If you want to pull a bottle out without scraping a knuckle, take one off every row.
The three numbers that decide door or floor
The door hanger is 14.2 in wide, 12.2 in tall and 7.5 in deep in the small size, 9.8 in in the large. Those three numbers answer most of the question before you look at a single product photo.
- Width. 14.2 in divided by a 3.5 in bottle is four across, whether the bottle is a sprayer or a canister. Two gallon jugs and nothing else.
- Depth. 7.5 in is two bottles deep. The 9.8 in version is also two deep, with a little air behind them. Neither takes a third row, however generous the number looks.
- Height. This is the one that rules things out. The 12.2 in has to cover two baskets, so each one gets roughly half. A sprayer with the trigger screwed on is about 11 in. It is not going on the door.
Which is the rule worth starting with: if most of what you own is taller than about 8 in, the door is not your storage. Put the money into floor height, and let the door hold pods, sponges and the one canister you reach for daily.
Floor height is capped by your plumbing, not by the product. The 1-tier unit is 15 in tall and the 2-tier is 19.1 in, and a gallon jug is already 11.8 in before you add a pump. Lifting one onto a shelf under a pipe is how a cabinet stops closing. If your clearance is the number you are unsure about, the size-first walkthrough measures it in the order that rules units out fastest.
Quick answers
How do I organize under the sink with pipes in the way?
Use an expandable organizer with height-adjustable shelves. Set the shelves to the sides of the P-trap and raise or lower them to clear the pipes and tall bottles.
What's the best under sink organizer for a small kitchen?
One that expands to fit your cabinet width and has pull-out baskets. Fixed shelves waste the deep space a small kitchen can't afford to lose.
Can I use a lazy Susan under the sink?
Only if your cabinet is wide and the P-trap is centered high. For most, a tiered pull-out organizer uses the space better.
How do I keep it from getting messy again?
Group by task (cleaning, dishes, spares), label the baskets, and do a 2-minute reset weekly so clutter doesn't rebuild.
Not sure what fits your cabinet? Read the complete under sink organization guide or shop the full range. Storing around a disposal is its own puzzle — fitting an under sink organizer around a garbage disposal is the page for that.
If your cabinet is on the narrow side, the order to fit things in changes — a 15 in cabinet with a pipe through it can't hold the stack a 30 in one can. Under sink organization ideas for small kitchens works from the cabinet you actually have instead of from a full-size base cabinet.
