The cabinet under your kitchen sink is where organization goes to die. Cleaning sprays fall over, trash bags unravel, sponges multiply, and somehow a flashlight from 2019 ends up behind the pipes. It is the most universally chaotic space in every kitchen, and it does not have to be.
The good news: organizing under the kitchen sink is a 30-minute project that requires zero tools, no drilling, and usually under $40 in products. This guide walks you through the entire process, from emptying the cabinet to installing a system that actually stays organized.
Before You Start: Measure and Assess
Before buying anything, take these three measurements:
- Width of the cabinet opening (not the inside, the door opening, since that is what products need to fit through)
- Height from cabinet floor to the bottom of the sink basin (this determines what fits vertically)
- Depth from front to back (most standard cabinets are 22-24 inches deep)
Also note where your pipes, garbage disposal, and water lines are. This determines whether you need an L-shaped organizer (pipes on one side), a U-shaped expandable shelf (pipes in the center), or a pull-out drawer organizers system (pipes high and out of the way).
Pro tip: Take a photo of your empty under-sink space with a tape measure visible. This is your reference when shopping.
Step 1: Empty Everything and Declutter
Pull everything out. Every bottle, sponge, trash bag roll, and mystery container. Put it all on the counter or floor.
Now sort into three piles:
Keep: Products you actively use at least once a month. This is your dish soap, surface cleaners, sponges, trash bags, and dishwasher pods.
Relocate: Items that do not belong under the kitchen sink. Extra light bulbs, batteries, tools, and pet supplies should live elsewhere. Duplicate products (three half-used bottles of the same cleaner) get consolidated.
Toss: Anything expired, rusty, leaking, or unidentifiable. Old sponges, dried-out cleaning wipes, and products you cannot identify should go.
Most people eliminate 30-40% of what was under their sink during this step alone.
Step 2: Protect the Cabinet Floor
Before putting anything back, protect the cabinet floor from leaks. Even a small drip from the pipes or a leaky bottle can cause water damage, mold, and warping over time.
Our recommendation: A waterproof silicone under-sink mat is the best investment you can make for this space. The GORILLA GRIP Waterproof Silicone Under Sink Mat is the most popular option on Amazon for good reason: it has raised edges to contain drips, it is dishwasher safe, and it trims to fit any cabinet size.
At around $20, it protects against damage that would cost hundreds to repair. This is the single product we recommend for every under-sink setup, regardless of budget.
Step 3: Create Zones
The key to lasting under-sink organization is zones. Each area of the cabinet has a job:
Zone 1: Daily essentials (front and center) – Dish soap, sponges, scrub brushes, and anything you reach for multiple times a day.
Zone 2: Cleaning supplies (main shelf area) – Surface sprays, glass cleaner, disinfectant wipes, and multi-purpose cleaner.
Zone 3: Refills and backstock (back and sides) – Extra trash bags, refill bottles, dishwasher pod refills, and bulk supplies.
Zone 4: Cabinet door (inside) – Mount a towel bar, adhesive hooks, or a door-mounted pocket organizer for dish towels, rubber gloves, or trash bag rolls.
Step 4: Install Your Organizer System
Option A: Pull-Out Sliding Organizer (Best for Most Kitchens)
Our pick: REALINN Under Sink Organizer, 2-Pack
This is the current #1 best-seller in the category. The L-shaped design fits around pipes, both tiers slide out, it holds up to 50 lbs per unit, and it requires zero tools to assemble.
Option B: Expandable Shelf Rack (Best for Pipes in the Center)
Our pick: SimpleHouseware Under Sink 2-Tier Expandable Shelf
This metal rack expands from 15 to 25 inches wide and has removable panels so you can customize around your specific pipe layout.
Option C: Portable Cleaning Caddy (Best Budget Option)
Our pick: madesmart Portable Cleaning Caddy
Adjustable dividers fit bottles of all sizes, the handle is comfortable for carrying, and it fits under standard sinks. Best option for renters.
Step 5: Maximize the Cabinet Door
Adhesive towel bar: Mount a Command adhesive towel bar on the inside of the door. Hang dish towels, rubber gloves, or loop spray bottle triggers over it. No drilling, no damage.
Door-mounted trash bag dispenser: A clear acrylic dispenser keeps trash bag rolls neat, visible, and easy to tear off.
Step 6: Label Everything (Optional but Powerful)
Labels are not just for Pinterest-perfect pantries. Under the sink, a simple label on each zone or bin prevents the slow creep back to chaos. Label your zones: “Daily,” “Cleaning,” “Refills.” When someone in your household puts something back, they know where it goes.
Maintenance: The 2-Minute Weekly Reset
- Slide out each organizer or bin
- Toss any expired or empty products
- Wipe down the silicone mat if needed
- Reset anything that migrated to the wrong zone
That is it. Two minutes, once a week, and your under-sink cabinet stays organized permanently.

Frequently Asked Questions
How do I organize under the kitchen sink with a garbage disposal?
Garbage disposals take up space on one side of the cabinet. Use an L-shaped organizer (like the REALINN) on the opposite side, and mount a towel bar or hooks on the cabinet door above the disposal for smaller items.
What is the best way to prevent leaks from damaging under-sink cabinets?
A silicone under-sink mat with raised edges is the most effective protection. It catches drips from pipes and bottles and can be removed and cleaned in the dishwasher. Check it monthly for pooled water.
How often should I reorganize under the kitchen sink?
A full reorganization is rarely needed if you do the 2-minute weekly reset. Most people find that a seasonal declutter (every 3-4 months) is enough to keep the system working well.
Can I organize under the sink without buying any products?
Yes. Repurpose items you already have: a magazine holder can store spray bottles upright, a small tension rod can hold spray triggers, and a plastic bin from another room can serve as a portable caddy.
The Bottom Line
Organizing under the kitchen sink is one of the fastest, cheapest, and most satisfying home projects you can do. Start by measuring your space, declutter ruthlessly, protect the floor with a silicone mat, and install a system with clear zones. The whole project takes 30 minutes and under $60.
