Stackable Under Sink Bins
Stackable bins are the fallback that fits everything: no rails, no legs, no mounting. Size each bin to its lane minus 0.5 in, stack no higher than bend height minus 1 in of lift-out room, and prefer open-front designs so the bottom bin stays reachable without unstacking.
Every other class on this site comes with a failure mode: rails cross pipes, legs stand under bends, cutouts miss traps. Bins have none. Their cost is access, digging, which is why the design details matter: open fronts, low lips, and stacks of two, never three.
Bins also modularize awkward space. A 5-in lane, a 9-in-tall gap under a low bend, the shallow strip in front of a trap: there is a bin dimension for each, and they reconfigure when the plumbing or the apartment changes.
Recommended layout
One footprint size per zone, mixed heights within it, everything liftable in one motion.
Start here: Split the cabinet into left and right lanes of about 7.1 in each. Use organizers that stop short of the trap bend, plus a low bin in the front strip.
Use this page's approach if
low bends, unknown plumbing, rentals, and as the second purchase that fills whatever lanes the main organizer left over.
Skip or adjust it if
you have one big clear lane you open daily; a slide-out will serve that lane better than digging through bins.
| Storage zone | Max width | Max depth | Max height | Best use |
|---|---|---|---|---|
| Left zone | 7.1 in | 17.5 in | 10 in | Narrow slide-outs, bin stacks, side baskets |
| Right zone | 7.1 in | 17.5 in | 10 in | Narrow slide-outs, bin stacks, side baskets |
| Front strip | 20.5 in | 8.4 in | 6 in | Low trays and one-motion daily bins |
| Back strip | 20.5 in | 14.5 in | 10 in | Only if every joint stays visible and reachable |

| Size class | Shop at or under | Fit | Where it goes | Notes | Link |
|---|---|---|---|---|---|
| Slim side basketvery narrow, 5-6 in lanes | 5.5 in W × 14 in D × 10 in H | Exact fit | Left zone | Rescues the sliver of space beside offset plumbing. Small capacity: best for brushes and refill packs stored upright. | Search this size |
| Stackable binnarrow, 5-7 in lanes | 6 in W × 14 in D × 7 in H | Exact fit | Left zone | Fits the tight lane every other class gives up on; rental-safe. Buy open-front: the lower bin must stay reachable without unstacking. | Search this size |
| Shallow vanity binsmall-format, low vanities | 8 in W × 10 in D × 5 in H | Exact fit | Front strip | Sized for low-bend vanities and 13-15 in door openings. Made for vanities; wastes space in a full-depth kitchen base. | Search this size |
| Stackable binstandard, 8-11 in lanes | 9 in W × 13 in D × 8 in H | Exact fit | Largest clear zone | The zero-risk default for any plumbing layout. Stack two high at most; the top bin needs 1 in of lift-out room. | Search this size |
| Cleaning caddycarry kit, handle included | 10 in W × 13 in D × 11 in H | Exact fit | Largest clear zone | The grab-and-go zone: parks front-center of the widest lane. Height listed with handle: the handle must clear the bend on lift-out. | Search this size |
| Low turntableflat, spins under the bend | 10 in W × 10 in D × 3.5 in H | Exact fit | Front strip | Puts small bottles a spin away in heights nothing else uses. Keep it off the trap ring: the spin needs a flat clear footprint. | Search this size |
| Low open trayfront strip, under the bend | 15 in W × 12 in D × 4 in H | Exact fit | Front strip | Lives under the trap where nothing else fits; doubles as a leak spotter. Must lift straight out in one motion without threading around the trap. | Search this size |
| U-shaped cutout shelffixed cutout, centered traps | 16 in W × 11 in D × 12 in H | Exact fit | Largest clear zone | Spans the trap when the cutout truly matches its position and width. Cutout must exceed the trap assembly's widest point by 1 in. | Search this size |
What not to buy here
Lidded stacks for daily items (the lid tax adds up), and bins so tall the top one cannot lift out under the bend.
Mistakes this page exists to prevent
- Buying one giant bin instead of two zone-sized ones, then wrestling it around the trap at every cleaning.
- Stacking three high and using the bottom bin as a graveyard.
- Choosing tapered bins for a tight lane; the top-out dimension is the real width.
Common questions
What bin sizes cover most cabinets?
Three footprints handle nearly everything: about 6 by 14 in for narrow lanes, 9 by 12 for standard lanes, and a low 14 by 10 tray for the front strip. Heights of 5 to 8 in stack under most bends.
Open-front or lidded?
Open-front for anything used weekly. Lidded only for chemicals around kids or for true backstock you touch quarterly.
Do bins need a mat underneath?
A waterproof tray under the whole arrangement is cheap insurance: it shows a drip before the cabinet floor drinks it.
