13 Under Kitchen Sink Organization Ideas for Cleaning Supplies

That cabinet under the sink often becomes a black hole for sponges, spray bottles, and mystery rags. But with a little planning, it can be one of the most functional spots in your kitchen.

These 13 ideas focus on modern, clean storage that makes grabbing what you need a breeze.

No more digging through a pile of bottles—just smart, stylish solutions that keep everything in its place.

1. Pull-Out Tiered Baskets for Instant Access

Under-sink cabinets are notorious for becoming a dark abyss of mismatched bottles and forgotten sponges. A pull-out tiered basket system changes that completely. With everything sliding out smoothly, you can see every spray cleaner and scrub brush at a glance.

The layered design keeps tall bottles on one level and smaller items on another, so nothing gets buried. It feels like giving your cleaning supplies their own organized little home.

Why It Works

• The sliding mechanism eliminates the need to crouch and dig through the back of the cabinet. You pull the entire rack forward and everything is right there. It saves time and frustration, especially during a quick clean-up.
• The tiered setup also maximizes vertical space, making use of every inch under the sink.

Best For

This idea is ideal for households with a large collection of spray bottles, cleaning cloths, and brushes. It works well in both small and standard under-sink cabinets. If you often buy cleaning products in bulk or have multiple surface-specific sprays, this system keeps them sorted and accessible.

Styling Tip

Stick with a matching set of neutral-colored spray bottles for a cohesive look. Decant your all-purpose cleaner, glass cleaner, and disinfectant into sleek amber or white glass bottles with black pumps. The uniform containers make the pull-out baskets look intentional and polished, even when the cabinet door is open.

2. Tension Rods for Spray Bottle Storage

That jumble of spray bottles under the sink—glass cleaner, all-purpose spray, disinfectant—always seems to tip over the moment you reach for one. A simple tension rod changes everything. Hang it horizontally near the front of the cabinet, and hook each bottle by its trigger.

They stay upright, visible, and easy to grab. It’s one of those small tweaks that makes a big difference in how clean and orderly the space feels.

Why It Works

• Tension rods require no drilling or adhesive, so they won’t damage your cabinet. They’re fully adjustable to fit different widths, and you can install or remove them in seconds. By keeping bottles off the floor, you free up shelf space for larger items like refills or scrub brushes.
• The upright position also prevents leaks from pooling under caps.

Best For

This idea shines in small kitchens or rental homes where you can’t make permanent changes. It’s also great for deep cabinets where bottles tend to get lost in the back. If you have a collection of spray bottles in similar sizes, this method keeps them neatly lined up like a mini cleaning caddy.

Styling Tip

Choose a tension rod with a matte black or brushed nickel finish to match modern hardware. For a cohesive look, group bottles with matching labels or pour cleaning solutions into uniform glass spray bottles. Keep the rod close to the cabinet opening so you can see every bottle at a glance.

3. Slim Drawer Organizers for Flat Items

Sponges, scrub pads, and gloves often end up in a wet pile under the sink. Slim drawer organizers—shallow plastic bins that slide in side by side—give each item its own spot. The result is a clean, modern look that keeps everything dry and easy to grab.

Why It Works

These organizers maximize vertical space without adding bulk. By separating flat items, you prevent mildew and clutter, and the clear or neutral bins maintain a streamlined appearance.

Best For

This works best for cabinets with limited depth or awkward plumbing. It's ideal for households that use multiple cleaning tools daily and want quick access without digging.

Styling Tip

Choose bins in a single color—white, gray, or clear—to keep the look cohesive. Label each bin with a simple tag for extra polish, and stack two shallow bins if you have extra height.

4. Clear Acrylic Caddies for Categorizing

Say goodbye to the under-sink black hole. Clear acrylic caddies bring instant order by grouping like items together—all-purpose cleaners in one, glass sprays in another, dish soap and scrub brushes in a third. The transparency means you can grab exactly what you need without pulling everything out.

It’s a simple system that makes your cabinet feel airy and intentional, not cluttered.

Why It Works

Acrylic caddies are lightweight, easy to wipe clean, and let you see supplies at a glance. They prevent bottles from toppling over and keep different categories from mixing, so you never accidentally grab the wrong spray. Plus, the uniform look creates a cohesive, organized appearance that feels modern and calm.

Best For

This setup is ideal for anyone with a standard under-sink cabinet who wants a no-fuss, budget-friendly solution. It works especially well if you have a mix of spray bottles, refills, and small tools that tend to get jumbled. Great for renters too, since it’s totally non-permanent.

Styling Tip

Stick with all-clear caddies for a seamless look, or choose ones with a subtle frosted finish for a softer aesthetic. If your cabinet has a dark interior, add a small LED strip or a battery-operated puck light so the acrylic really pops. Keep the caddies shallow enough to slide out easily, and label each one with a small tag for extra clarity.

5. Over-the-Door Rack for Extra Storage

The inside of your under-sink cabinet door is prime real estate that often goes unused. By attaching a slim over-the-door rack, you can instantly create a dedicated spot for sponges, brushes, and small bottles that would otherwise clutter the counter or get lost in the cabinet's dark corners. It’s a simple upgrade that makes your cleaning routine feel more streamlined and intentional.

Why It Works

This rack keeps frequently used items within easy reach while maximizing vertical space. The door-mounted design means nothing gets buried at the back of the cabinet, and the open wire or mesh construction allows air to circulate, preventing mildew on damp sponges and brushes.

Best For

Perfect for small kitchens where every inch of storage counts, or for anyone who wants to keep their most-used cleaning tools visible and accessible without taking up shelf space.

Styling Tip

Choose a rack with a clean, modern finish like matte black or brushed nickel to complement your cabinet hardware. Stick to a neutral color palette for the items you store—white, gray, or clear containers keep the look cohesive and uncluttered.

6. Stackable Bins for Vertical Space

Under the sink, every inch counts. Stackable plastic bins turn that awkward vertical gap between plumbing and cabinet top into usable storage. Think clear bins for sponges and rags, or opaque ones for refill bottles—each layer adds a new shelf without any installation.

It’s a simple swap that makes the space feel twice as large and infinitely more organized.

Why It Works

Stackable bins create multiple levels of storage in a single footprint, so you can separate items by category without mixing. Clear bins let you see everything at a glance, while opaque ones hide clutter for a cleaner look. The modular design means you can adjust the stack height to fit around pipes or odd angles.

Best For

This idea shines in small kitchens or rental cabinets where you can’t add permanent shelving. It’s also perfect for households with lots of cleaning supplies—sponges, scrub brushes, spray bottles—that need to be corralled but still accessible.

Styling Tip

Stick to all-white or clear bins for a modern, streamlined look. Add small labels on the front (like “rags” or “sponges”) using a label maker or chalk labels for a polished touch. Keep the most-used items in the top bin for easy grab-and-go.

7. Lazy Susan for Corner Access

That deep corner under the sink often becomes a black hole for sponges and scrub brushes. A lazy Susan spins everything into reach with a simple twist, turning wasted space into a functional hub. It’s one of those small tweaks that makes daily cleaning feel effortless.

Why It Works

By rotating items forward, a lazy Susan eliminates the need to dig around in the back. You can see every bottle and brush at a glance, which means less time searching and more time actually cleaning. Plus, it keeps the cabinet tidy by grouping like items together.

Best For

This idea shines in deep or L-shaped cabinets where back corners are hard to access. It’s also perfect for renters who want a non-permanent solution—no drilling or adhesive required.

Styling Tip

Choose a sleek, clear acrylic lazy Susan for a modern look that blends in. Or go with a bamboo one for warmth. Keep the spin surface clean by wiping it down monthly to prevent grime buildup.

8. Magnetic Strips for Metal Tools

Under the sink, small metal tools like scrub brushes and tweezers often end up scattered or lost. A magnetic strip mounted on the cabinet wall turns that chaos into an organized display. It’s a sleek, modern solution that keeps everything visible and within reach, without taking up any floor space.

Why It Works

Magnetic strips use vertical space that’s otherwise wasted. They hold metal items securely, so you can grab what you need without digging through a bin. Plus, they make it easy to see at a glance if something’s missing or needs cleaning.

Best For

This idea is perfect for anyone who uses metal scrubbers, small tongs, or stainless steel bottles under the sink. It’s also great for renters since magnetic strips are easy to install and remove without damaging cabinets.

Styling Tip

Choose a slim, white or brushed nickel strip to blend with modern hardware. Group similar tools together—like all scrub brushes on one strip and measuring spoons on another—for a clean, intentional look.

9. Under-Sink Shelf for Layering

Adding a simple wire shelf under the sink instantly doubles your storage without any major renovation. The open design keeps everything visible and easy to grab, so you're not digging through a dark cabinet for that spray bottle. It's a small change that makes a big difference in how organized and airy the space feels.

Why It Works

A wire shelf creates two distinct levels, making use of vertical space that often goes wasted. Tall bottles like all-purpose cleaner or floor soap sit comfortably on the bottom, while smaller items like scrub brushes and dish soap line up neatly on top. The open grid also allows air to circulate, preventing musty odors and making spills easy to spot and wipe up.

Best For

This setup is ideal for standard under-sink cabinets that have a single open space with no built-in dividers. It works especially well if you have a mix of tall and short cleaning products and want quick access to everyday items without piling everything in a bin.

Styling Tip

Choose a shelf with a rust-resistant finish, like coated steel or chrome, to hold up against moisture. Keep the top layer for daily-use items and group them by function—for example, dish soap and sponge on one side, surface spray and microfiber cloth on the other. Add a small plastic tray on the bottom to catch drips from bottles.

10. Hanging Buckets for Small Supplies

Small metal buckets clipped onto a rail or hook system bring a playful, industrial touch to the under-sink cabinet. They keep sponges, gloves, and scrub brushes within easy reach while freeing up floor space. The look is clean and intentional—like a tiny hardware store display, but for your cleaning kit.

Why It Works

Hanging buckets eliminate the need to dig through a bin or shelf for small items. Each bucket holds one category, so you can grab a sponge or a pair of gloves without rummaging. The open design also lets air circulate, helping sponges dry faster and preventing musty odors.

Best For

This idea works well in small to medium kitchens where every inch of cabinet space counts. It's especially useful if you have a deep cabinet that makes it hard to reach items in the back. The buckets can also be used under a bathroom sink for organizing toiletries or cleaning supplies.

Styling Tip

Choose buckets in a matte black or brushed nickel finish to match modern hardware. For a cohesive look, stick to one metal tone throughout the cabinet. If your cabinet interior is dark, line the back with a peel-and-stick wallpaper in a subtle pattern to add contrast and make the buckets pop.

11. Drawer Inserts in a Pull-Out Drawer

A pull-out drawer under the sink is a game-changer for cleaning supplies, but without proper organization, bottles still topple and clutter takes over. Adding adjustable dividers or drawer inserts transforms that deep drawer into a neatly segmented space where every spray bottle and scrub brush has its own spot. The result is a clean, modern look that feels intentional and keeps your daily cleaning routine smooth.

Why It Works

Adjustable dividers prevent bottles from tipping over when the drawer opens or closes, saving you from spills and frustration. They also make it easy to categorize supplies—all-purpose cleaners on one side, glass sprays on another—so you can grab what you need without rummaging.

Best For

This idea is perfect for kitchens with a pull-out drawer base cabinet, especially if you have a collection of spray bottles, sponges, and small cleaning tools. It works well in both standard and deep drawers, and the dividers can be customized to fit different bottle sizes.

Styling Tip

Choose clear or neutral-toned drawer inserts to keep the look streamlined and modern. For a cohesive aesthetic, match the inserts to your cabinet’s interior finish—white or light gray works with most kitchens. Add a small tray for sponges or scrub brushes to keep them from rolling around.

12. Labeled Baskets for a Clean Look

Bringing order under the sink doesn't have to mean boring plastic bins. Woven or plastic baskets with simple labels like 'All-Purpose' or 'Glass Cleaner' create a tidy, uniform look that makes grabbing supplies effortless. The combination of natural texture and clean labeling feels both modern and approachable, turning a forgotten cabinet into a space that actually sparks joy.

Why It Works

Labels eliminate the guesswork when you're in a hurry, so everything has a home and stays that way. Baskets corral bottles and sponges, preventing them from toppling over, and the cohesive look makes the cabinet feel intentional rather than chaotic.

Best For

This idea shines in kitchens where multiple people use the cleaning supplies, like busy family homes or shared apartments. It's also perfect for anyone who loves a minimalist, organized aesthetic but wants to keep it practical.

Styling Tip

Choose baskets in a neutral tone—like seagrass or matte white—to keep the look calm. Use a label maker or chalk labels for a crisp finish, and group items by use: all-purpose cleaners in one, glass and surface sprays in another, and sponges or scrub brushes in a third.

13. DIY Pegboard for Custom Layout

A pegboard under the sink turns wasted vertical space into a flexible storage wall. Instead of digging through a pile of bottles and brushes, you can hang everything within easy reach. The look is clean and intentional, especially when you choose a pegboard that matches your cabinet interior or paint it a soft neutral tone.

Why It Works

Pegboards let you rearrange hooks and baskets whenever your cleaning supplies change. No more sticky shelves or overcrowded bins—each item gets its own spot, and you can see everything at a glance. The open layout also makes it easy to wipe down spills and keep the area truly clean.

Best For

This idea is perfect for under-sink cabinets with a single door or a wide double-door setup. It works especially well if you have a mix of spray bottles, brushes, and small dustpans that usually end up in a tangled heap.

Styling Tip

Paint the pegboard the same color as your cabinet interior (white or light gray) so it blends in. Use a mix of small hooks for bottles, larger hooks for dustpans, and a small basket for sponges. Keep the layout balanced—leave some empty pegs for future additions.
