The organized under-sink formula

The cabinet under the sink is one of the most awkward storage spaces in the whole house because of the plumbing running through the middle of it. Most people just push everything into one flat pile and shut the door, which is exactly why it turns into a mess again within a week.

The fix isn't more containers, it's a system: pull-out access so nothing hides in the back, stacked storage that uses the height of the cabinet, a turntable that works around the pipes instead of against them, door storage for daily items, labeled bins for anything small, and a protective liner underneath it all.

01 · Slide & Access

Pull-Out Sliding Drawer Organizer

The single upgrade that ends daily digging and searching.

Most of what's stored under the sink becomes invisible the moment it's pushed toward the back, because you have to crouch down and dig past bottles just to find one thing. A sliding drawer glides forward on tracks and brings everything to you instead.

  • Slides forward on tracks so back-of-cabinet items become visible instantly.
  • Fits most standard cabinet widths without tools or drilling.
  • Holds spray bottles, soap refills, or trash bags upright and steady.
Avery's styling note: If you only add one thing to this cabinet first, start here. Put your most-used bottle right at the front of the slide.

02 · Vertical Storage

Stackable Under-Sink Drawer Organizer

The stacking system that finally uses the cabinet's height.

Most under-sink cabinets waste vertical space because everything sits in one flat layer. Stackable drawers let you build upward around the pipes instead of piling items on top of each other.

  • Modular drawers stack and interlock so you can build the layout around your pipes.
  • Keeps sponges, gloves, and small bottles separated instead of jumbled together.
  • Pull-out drawers mean you never unstack the whole tower to grab one item.
Avery's styling note: Leave the top drawer open for whatever you grab daily — a junk drawer with a lid is still more organized than a loose pile.

Two tier expandable shelf riser for under sink cabinet
03 · Vertical Space

2-Tier Expandable Shelf Riser

The riser that turns one flat shelf into two usable levels.

A single flat shelf almost always wastes the empty air above it. An expandable two-tier riser adds a second level, so tall bottles and short items each get their own spot instead of getting stacked on top of one another.

  • Expands or contracts to fit narrow or wide cabinets around the pipes.
  • Adjustable legs help it clear plumbing on either side.
  • Doubles usable shelf space without adding any extra footprint.
Avery's styling note: Put taller bottles on the bottom tier and lighter, shorter items on top so the riser stays balanced.

04 · Corner & Pipe Storage

Lazy Susan Turntable Organizer

The turntable that works around pipes instead of fighting them.

The area directly around the plumbing is usually the most wasted part of the cabinet. A round turntable spins in place, so you can reach items stored behind the pipe without pulling everything else out first.

  • Rotates a full 360 degrees, so nothing gets pushed to the back and forgotten.
  • Round shape naturally works with the curved space around plumbing.
  • Ideal for oils, sprays, or anything you reach for in small amounts often.
Avery's styling note: Use one turntable on each side of the pipe rather than one large tray — it spins easier and actually holds more.

Hanging organizer caddy mounted on inside of cabinet door
05 · Door Storage

Over-the-Cabinet-Door Hanging Caddy

The storage layer that doesn't use any shelf space at all.

The inside of the cabinet door is almost always empty, even though it's some of the easiest space to reach. A hanging caddy adds pockets or racks there, so sponges, gloves, and small tools stay off the shelf entirely.

  • Hangs over a standard cabinet door with no drilling or hardware required.
  • Frees up shelf space for larger items like bottles and bins.
  • Keeps damp items like sponges and brushes away from stored paper goods.
Avery's styling note: Reserve the door caddy for whatever you touch every single day, like gloves or a scrub brush. It's your most convenient spot in the cabinet.

Clear stackable storage bins with labels for cabinet organization
06 · Small Item Organization

Clear Stackable Storage Bins with Labels

The bins that make everything visible at a glance.

Loose bottles and small items get lost the moment the cabinet door closes. Clear bins group similar items together and let you see what's inside without opening every bin, and labels remove any guesswork later.

  • Clear sides mean you can identify contents without lifting the lid.
  • Labels keep categories consistent: cleaning, refills, tools, extras.
  • Stackable design uses vertical space instead of spreading items across the cabinet floor.
Avery's styling note: Group by task, not by product type. A "weekly cleaning" bin is easier to grab in one motion than five separate spray bottles.

Waterproof non-slip shelf liner for under sink cabinet
07 · The Finishing Touch

Waterproof Non-Slip Shelf Liner

The protective layer that keeps the whole system looking new.

Under-sink cabinets deal with drips, spills, and moisture more than almost any other storage spot in the house. A waterproof liner protects the wood underneath and keeps bottles from sliding every time the door opens.

  • Waterproof surface protects wood or laminate from leaks and spills.
  • Non-slip texture keeps bottles upright even when the door swings open quickly.
  • Wipes clean in seconds, which is far easier than scrubbing a bare cabinet floor.
Avery's styling note: Line the cabinet before you add anything else. It's much easier to lay flat before bins and organizers are already in place.

How to organize the full cabinet without losing storage to the pipes

The secret is to build the system in layers instead of piling everything in at once. Let each zone do one job: the floor, the corners around the plumbing, the back wall, the shelf above, the door, and the small loose items.

  1. Start by lining the cabinet floor so everything added afterward sits on a clean, protected surface.
  2. Add a turntable on each side of the pipe so the awkward center space finally gets used.
  3. Place a pull-out or stackable drawer along the back wall for anything you don't need daily.
  4. Use an expandable shelf riser wherever there's flat, unused space above a shelf.
  5. Hang a caddy on the inside of the door for daily-use items like gloves and sponges.
  6. Group anything small and loose into labeled clear bins so nothing hides at the back.

Avery's final note: An organized cabinet doesn't need more containers. It needs a system that works around the pipes instead of against them.
