How to Effectively Organize the Space Under Your Kitchen Sink

The area under your kitchen sink is one of the most overlooked, and overstuffed, spaces in the entire home. It's where cleaning supplies go to disappear, sponges multiply mysteriously, and plastic bags seem to form an unofficial colony. 

But what if this notoriously chaotic space could actually work for you?

Whether you're living in a cozy apartment or managing a bustling household, organizing your under-sink cabinet can transform your kitchen experience. With the right strategy (and a few space-saving helpers), it’s totally possible to turn clutter into calm.

Let’s walk through smart, sustainable under sink organization ideas to make your kitchen cleaner, greener, and easier to navigate.

Clearing and Categorizing

The first step toward under-sink organization is a complete reset. It’s easy for this area to become a black hole of half-used sprays, random sponges, and forgotten cleaning supplies. Before you can make meaningful improvements, you need to see what you’re working with. Literally.

Start by removing every single item from beneath your sink. Set everything out on a towel or large surface nearby so you can evaluate what’s actually been taking up space. 

This alone might reveal expired products, duplicates, or things that simply don’t belong there (looking at you, lost sock or broken scrub brush).

Once everything’s out, sort items into clear categories. 

A few common ones include:

• Everyday cleaning: all-purpose sprays, disinfecting wipes, glass cleaner, microfiber cloths, surface sanitizing spray
• Specialty items: stainless steel polish, oven cleaner, grout brush, hard water stain remover, stovetop scraper
• Dishwashing essentials: HeySunday dishwasher sheets, dish soap, scrub sponges, dishwasher rinse aid, bottle brush
• Tools and accessories: rubber gloves, sink stoppers, drain brush, reusable cleaning gloves, collapsible bucket

This is also a great time to identify what you use most and what you could eliminate. Anything expired, crusted over, or unused in the last six months? It’s time to responsibly toss or recycle it.

Deep Cleaning the Area

Now that the space is clear, take advantage of the moment to give your under-sink cabinet a proper refresh. 

Use a vacuum or handheld duster to clear out any debris that’s built up in the corners. Then wipe down all surfaces with a disinfectant spray or your favorite natural cleaner (a vinegar and water solution works great for this).

Don't forget to pay attention to the edges, corners, and especially the base of the cabinet. These areas often collect spills or mold from leaking bottles and wet sponges. If there’s been a past spill or lingering smell, you might even consider lightly sanding the base panel (if it’s wood) and resealing it with a protective liner.

To make future upkeep easier, add a washable or waterproof shelf liner. This creates a barrier between the cabinet and your products, helping prevent water damage and making cleanup much faster next time.

Tip: Choose a liner with a non-slip grip or one that’s textured to prevent items from sliding around each time you open the doors.

With your space clean, cleared, and categorized, you’ve laid the groundwork for a beautifully organized and functional under-sink setup. 

Planning Your Under Sink Layout

Before buying bins or stuffing anything back under the sink, it’s essential to take a step back and actually assess the space you’re working with. 

The area beneath your kitchen sink is notorious for being awkward. There are usually pipes, water lines, garbage disposal units, or oddly placed supports that can limit your kitchen cleaning storage options. 

But with a little planning, you can make even the most cramped cabinet feel surprisingly functional.

Measure First, Always

Start by grabbing a measuring tape and taking down the full width, depth, and height of your under-sink space. Then, measure around key obstacles like the plumbing, garbage disposal, or water filter system so you can plan storage around them. 

Don’t forget to note how far your cabinet doors open and if there’s a center divider or lip that could get in the way of drawer-style bins.

Pro tip: Use painter’s tape to map out where organizers or bins will sit. It’s a great way to visualize spacing before making a single purchase.

Choose the Right Storage Style

Once you have the measurements, it’s time to think strategically about your layout. The most effective under-sink systems work up rather than out, meaning stackable solutions are your best friend. 

Look for adjustable or tiered shelving units that leave space for plumbing underneath while giving you usable surface area above.

Here are a few smart shelving and layout ideas:

• Stackable drawers are ideal for smaller items and various odds & ends.
• Tiered organizers create levels for bottles and sprays, so you don’t lose anything behind taller items.
• Tension rods can be installed to hang spray bottles from their nozzles, making the most of vertical space.
• Slide-out baskets or bins work well if you want easier access to items in the back of the cabinet.
• Expandable shelving adjusts to fit around tricky pipe configurations while still offering solid storage above and below.

This step might feel a little technical, but trust us. A well-planned layout is what transforms your under-sink space from a chaotic mess into a smart, usable storage zone. And once the right structure is in place, the rest of the organization process becomes a whole lot easier.

Essential Under Sink Organization Tips

Once your layout is mapped and your shelves are in place, the real organizing can begin. This is where strategy meets functionality because it’s not just about where things go, but how easy it is to access them in the chaos of a weekday clean-up or a post-dinner dish blitz. 

The goal? A setup that works with your routine, not against it.

Keep Frequently Used Items Within Easy Reach

Think about what you grab for daily. Maybe it’s your all-purpose spray, a clean sponge, or your trusty pack of HeySunday dishwasher sheets. These should be front and center, not buried behind a gallon of floor cleaner you only use once a month.

Create a “daily use” zone near the front of your cabinet. This might be a narrow bin that holds a few go-tos or a small lazy Susan that lets you spin and grab quickly. 

Label it if it helps other household members stay consistent (because let’s be real, no one wants to answer “where’s the dish soap?” three times a week).

Use Tiered Shelves and Clear Bins for Quick Access

If you’ve ever knocked over three bottles just to get to one, you know the value of visibility. Tiered shelves let you elevate items like sprays and cleaners so nothing is hidden in the back. 

Opt for clear or translucent bins and drawers, which help you spot what you need without rummaging.

Even better? Group like items together. 

For example:

• One bin for dishwashing essentials
• Another for surface sprays 
• A separate one for specialty cleaners

Not only does this streamline your process, but it also makes restocking super simple. You’ll instantly see when something’s running low.

Choose Waterproof or Rust-Proof Shelves

Under-sink cabinets are prone to leaks, spills, and general humidity. That means your storage solutions need to be tough enough to withstand it all. Choose materials like plastic, coated metal, or bamboo that are resistant to moisture and rust.

Avoid anything with fabric liners or untreated wood. They’ll absorb spills and warp over time. Some of the best under-sink organizers are made from durable, non-porous materials that you can simply wipe clean if there’s a mess.

Bonus tip: Add a waterproof shelf liner or a shallow tray beneath your bins to catch any drips. It’s a small step that can prevent mold, damage, or nasty surprises down the line.

Incorporate Space-Saving Solutions

When it comes to organizing under the kitchen sink, space is often your biggest challenge. Between the garbage disposal, water pipes, and oddly shaped cabinetry, it’s rare to find a tidy rectangular space that plays nicely with standard storage tools. 

That’s where smart, space-saving solutions come in. These are the small changes that make a big difference in both function and aesthetics.

Use Narrow Caddies to Store Sponges and Brushes

Forget bulky bins that eat up your limited shelf space. Instead, invest in slim, narrow caddies or vertical organizers designed specifically for tight spots. These fit snugly along the cabinet walls or inside the door, making the most of those overlooked corners.

Use one narrow caddy for:

• Dish brushes and bottle scrubbers
• A few microfiber cloths rolled tightly
• Magic erasers or sponge refills
• A travel-sized stain remover or counter spray

Wall-mounted or adhesive-backed caddies can free up even more shelf space. Stick them to the inside of your cabinet door or on the cabinet wall for fast access and clutter-free counters. 

Bonus: If you have kids or pets, it’s a great way to store sharp scrubbers or chemical-based cleaners out of reach.

Switch to HeySunday Dishwasher Sheets for Compact Storage

One of the easiest ways to free up under-sink space? Rethink the size and shape of your cleaning products. Traditional dishwasher detergents take up valuable real estate and leave behind bulky packaging waste.

That’s why HeySunday dishwasher sheets are a game-changer. These ultra-thin, pre-measured sheets pack powerful cleaning into a lightweight envelope you can tuck into the smallest drawer, bin, or caddy. No more half-empty jugs toppling over every time you reach for something in the back.

Sustainable Storage

Organize under your kitchen sink for more than convenience. It’s also an opportunity to make more eco-conscious choices. Choosing sustainable storage solutions helps reduce your home’s environmental impact while still looking stylish and functioning beautifully.

Choose Eco-Friendly Bins or Baskets

Look for containers made from recycled plastic, bamboo, or sustainably sourced wood. These materials are durable, low-waste, and resistant to moisture, making them ideal for the under-sink zone. 

Long-Term Kitchen Sink Organization Strategies

Once your under-sink area is neat and functional, the goal is keeping it that way. Regular maintenance prevents clutter from creeping back in and helps your system adapt to your family’s changing needs.

Schedule Regular Decluttering

Start by scheduling quick monthly cleanouts. Toss empty bottles, dried sponges, or products you no longer use. 

Prevent the mess from returning by scheduling quick cleanouts:

• Monthly sweep: Set a reminder to pull out your bins and take stock of what’s inside. Toss empty containers, expired products, and items you no longer use.
• Seasonal refresh: At the start of each season, do a slightly deeper declutter. Wipe down surfaces, check for leaks, and reassess whether your current setup still fits your needs. You might have stocked up on extra cleaning products during flu season or added new tools over the holidays — now’s the time to reset.
• One-in, one-out rule: Any time you buy a new product for this area, get rid of one that’s used up, broken, or no longer relevant. This simple habit keeps overflow at bay.

Decluttering doesn’t need to be an all-day project. In most homes, five to ten minutes per month is all it takes to maintain the peace under your sink.

Maintain Labeled Zones

To keep things orderly, stick to labeled zones. Group items like dishwashing supplies, multipurpose cleaners, and backups in clearly marked bins. This makes it easy for everyone in your household to return things to their place. If your needs shift, don’t be afraid to update labels or rearrange bins to match.

Final Thoughts: Create a Clutter-Free Kitchen You’ll Actually Enjoy

The space under your sink doesn’t have to be chaotic. With thoughtful planning and a few small upgrades, it can become a functional, streamlined part of your daily routine.

From clear bins and tiered shelving to compact products like HeySunday dishwasher sheets, it’s never been easier to make your kitchen work smarter, not harder.
