Best Under Kitchen Sink Organizers for Small Kitchens
Last updated: October 18, 2026
The cabinet under a kitchen sink is where cleaning sprays, dish soap refills, trash bags and sponges end up in a pile. In a small kitchen it's also prime storage space — if you can work around the drain pipe and, often, a garbage disposal. We compared five organizers by their listed size and layout so you can pick ones that fit on either side of the plumbing.

Our picks
madesmart 2-Tier Organizer with Dividers
Size: 14.5 inches long, 9 inches wide, 10.6 inches tall.
Build: two sliding baskets with adjustable dividers and easy-grip handles.
Pros
- 9 inches wide — fits beside most drain pipes
- Both baskets slide out, so you can reach the back without emptying the cabinet
- Dividers keep spray bottles upright and sponges separate
Cons
- Plastic, not metal
- 10.6 inches tall; check the height under a garbage disposal
- One organizer per pack
REALINN 2-Tier Slide-Out Organizer (2-Pack)
Size: 14.2 inches wide, 10.6 inches deep, 11 inches tall. Top basket about 14.2 x 4.8 inches, bottom basket about 14.2 x 8.9 inches.
Build: white painted steel, two tiers that slide out; two organizers per pack.
Pros
- Steel build handles heavy cleaning bottles
- Two in a pack — one for each side of the pipe
- Bottom basket is deep enough for tall spray bottles
Cons
- 14.2 inches wide each; two side by side need about 29 inches plus room for the pipe
- Painted steel can chip and rust if water sits on it
- Shallow top basket suits only small items
Kitstorack 3-Tier Height-Adjustable Organizer (2-Pack)
Build: thickened metal pull-out organizer with three tiers and adjustable height; two per pack.
Pros
- Three tiers — the most levels in this guide
- Height adjusts to fit around pipes and a garbage disposal
- Two in a pack for both sides of the cabinet
Cons
- The listing title doesn't state exact dimensions; measure your cabinet against the listing details
- Three tiers need more height than two
- Metal can rust if leaks aren't wiped up
PXRACK Adjustable Under-Sink Organizer (2-Pack)
Build: two 2-tier pull-out organizers in thickened metal, with adjustable height so the upper tier can sit around pipes.
Pros
- Adjustable height helps it fit under a drain trap or disposal
- Metal frame for heavy bottles
- Two in a pack
Cons
- The listing title doesn't state exact dimensions
- Two tiers only
- Wipe up leaks to avoid rust
Vtopmart Clear Stackable Storage Drawers (4-Pack)
Size: 7.5 x 6 x 4.4 inches per drawer.
Build: clear acrylic (BPA-free) stackable drawers.
Pros
- Only 4.4 inches tall, so they fit under low pipes
- Stack where you have height, spread out where you don't
- Clear fronts show sponges, dishwasher pods and bags at a glance
Cons
- Small — not for full-size spray bottles
- No pull-out frame
- Plastic can crack if overloaded
How to measure under your kitchen sink
- Measure each side of the plumbing, not the whole cabinet. The pull-outs here are 9 to 14.2 inches wide.
- Check for a garbage disposal: it hangs lower than a plain drain and takes the middle of the cabinet. Adjustable-height organizers like the Kitstorack and PXRACK help here.
- Measure the height to the lowest pipe on each side.
- Measure the depth from the back wall to the door, and check the door opening — the center stile can be narrower than the inside.
- Leave space for pull-outs to slide fully forward.
Pull-out shelves vs. stackable drawers
Pull-out shelves like the madesmart, REALINN, Kitstorack and PXRACK let you reach the back of a deep cabinet without emptying it. Stackable drawers like the Vtopmart are smaller and fit odd gaps, including the low space under a pipe, but hold less. Many kitchens use both: pull-outs on each side, small drawers in the gaps.
Final recommendation
For most small kitchens, the madesmart 2-tier is the best balance: 9 inches wide, both baskets slide out, and the dividers keep bottles upright. For a deep cabinet and heavy bottles, the steel REALINN pair works well. If you have a garbage disposal, the adjustable Kitstorack (3 tiers) or PXRACK (2 tiers) fit around it, and the small Vtopmart drawers fill the gaps under the pipes.

Frequently asked questions
- How do I organize under the kitchen sink with a garbage disposal?
- Use two organizers, one on each side of the disposal, and choose adjustable-height models like the Kitstorack or PXRACK so the upper tier clears the pipes.
- What size under-sink organizer do I need?
- Measure the width beside the plumbing, the depth to the door and the height to the lowest pipe. The madesmart is 9 inches wide; the REALINN is 14.2 inches.
- Metal or plastic under-sink organizers?
- Metal is stronger for heavy bottles but can rust if leaks aren't wiped up. Plastic doesn't rust but is less rigid.
- Are pull-out under-sink organizers worth it?
- Yes, in a deep cabinet. They bring items at the back to the front so nothing gets lost.
- What should I keep under the kitchen sink?
- Dish soap refills, cleaning sprays, sponges, dishwasher pods and trash bags. Keep chemicals away from food and out of reach of children.
