Stackable Clear Bins
Cozyla Digital Calendar+ 15.6'' Touch Wall Planner
Check PriceStackable clear bins are absolute game-changers for under-sink storage because they let you see exactly what you have at a glance. No more digging through mystery piles looking for that one specific cleaner! Choose bins in different sizes to accommodate everything from tall spray bottles to small sponges. The stackable design means you’re using vertical space efficiently, which is crucial in those awkward cabinet depths. Look for bins with handles on the sides so you can easily pull them out when you need something from the back. Label each bin by category—cleaning supplies, trash bags, extra toiletries—and you’ll never waste time searching again. The clear plastic also makes it easy to know when you’re running low on supplies, which is perfect for keeping your shopping list updated without having to do a full cabinet inventory every week.
I love that these stack securely so you can actually maximize all that vertical space under your sink.
Lazy Susan Turntable
A lazy Susan under your sink is like having a personal assistant who hands you exactly what you need without the awkward reaching and stretching. These rotating platforms are perfect for corralling all those bottles and containers that usually end up pushed to the back corner, never to be seen again. Just give it a spin and everything comes right to you! They work brilliantly for cleaning supplies, hair products, or even extra dish soap and hand soap refills. Choose a lazy Susan with raised edges to prevent bottles from sliding off during rotation. For maximum efficiency, group similar items together on the turntable so you always know which section to spin to. This hack is especially useful if you have deep cabinets or corner sinks where reaching the back feels like an archaeological expedition. Plus, it keeps everything visible and accessible, which means you’ll actually use what you have instead of buying duplicates.
I love that this turntable makes the most of that awkward under-sink space we all struggle with.
2-Tier Sliding Rack
Two-tier sliding racks are the ultimate solution for making use of that awkward vertical space while keeping everything within easy reach. These ingenious organizers pull out like a drawer, bringing the back items forward effortlessly. The two-tier design doubles your storage capacity without requiring any installation or permanent changes to your cabinet. Perfect for storing cleaning products on the bottom tier and sponges, scrubbers, and gloves on top. The sliding mechanism means you never have to get on your hands and knees to find what rolled to the back three months ago. Look for racks with sturdy construction that can handle the weight of multiple bottles without wobbling. Many models fit around standard sink pipes, which is essential for maximizing usable space. This setup is particularly fantastic for busy moms who need quick access to cleaning supplies during those inevitable spills and messes that happen throughout the day.
I love that this one slides out so you can actually reach everything hiding in the back.
Triangular Corner Shelves
Corner spaces under the sink are notoriously difficult to utilize, but triangular corner shelves are specifically designed to conquer that wasted real estate. These wedge-shaped organizers fit snugly into corners, transforming dead space into functional storage. They’re perfect for storing smaller items like sponges, scrub brushes, and travel-sized products that tend to get lost in larger bins. The angled design allows you to stack multiple shelves vertically, creating layers of storage without blocking access to the main cabinet area. Installation is typically simple—most models either stack freely or attach with adhesive strips, meaning no tools required. The open design makes it easy to see and grab what you need quickly. If you have a corner sink or an L-shaped cabinet configuration, these shelves become even more valuable. They’re also great for bathrooms where you need to store extra toiletries, makeup, or first-aid supplies in an organized, accessible way.
I love that this fits taller bottles easily, so you're not constantly rearranging your counter.
Tension Rod Dividers
Tension rods aren’t just for shower curtains—they’re secret weapons for creating vertical dividers under your sink! Install one or two tension rods horizontally near the front of the cabinet to create slots for storing flat items like cutting boards, baking sheets, or cleaning cloths. You can also mount them vertically to create compartments that keep spray bottles upright and separated. The beauty of tension rods is that they require zero drilling or permanent installation; they simply twist to expand and grip the cabinet walls. This means you can adjust their position anytime your storage needs change. For an extra clever hack, hang spray bottles from a horizontal tension rod by their triggers, freeing up floor space below for bins or other organizers. Use multiple rods at different heights to create a custom organization system that perfectly fits your collection of supplies. They’re incredibly affordable and can be found at any home goods store.
I love that this one adjusts to fit whatever space you need without any drilling required.
Adhesive Door Baskets
The inside of your cabinet door is prime real estate that usually goes completely unused, but adhesive door baskets change that immediately. These wire or plastic baskets attach to the inside of cabinet doors with strong adhesive strips, creating instant storage without any drilling. They’re perfect for storing items you reach for frequently—dish sponges, scrubbers, gloves, or small cleaning supplies. In bathroom cabinets, use them for hair tools, makeup, or extra toiletries. The over-door placement keeps these items visible and accessible while freeing up valuable floor space inside the cabinet for larger items. Make sure to measure your cabinet depth before purchasing to ensure the door can still close properly with the baskets attached. Choose baskets with open-front designs for easy grabbing. Some models come with adjustable hooks or multiple basket tiers for even more storage capacity. This simple hack maximizes every inch of available space and keeps your most-used items at your fingertips.
I love that this comes with everything you need to install it right away—no hunting for extra supplies.
Clear Plastic Drawers
Clear plastic drawer units bring order to chaos by giving every item its own designated home. These drawer systems typically come in three to five stackable tiers, each with a pull-out drawer that glides smoothly. The transparent plastic lets you instantly see what’s inside each drawer without opening them, saving precious time during busy mornings or frantic cleaning sessions. Dedicate different drawers to specific categories—one for trash bags, one for dish soap refills, one for sponges and scrubbers, and another for miscellaneous supplies. The drawer format prevents items from toppling over or getting jumbled together like they do in open bins. Look for units sized to fit your specific under-sink dimensions, as they come in various widths and heights. Some models have removable dividers inside each drawer for even more customization. This system is especially helpful if you have kids who help with chores, as they can easily find and return items to the correct drawer without creating a mess.
I love that these clear drawers work in literally every room—bathroom, kitchen, pantry, you name it.
Hanging Spray Bottle Rack
Spray bottles are notorious for taking up way too much floor space and constantly falling over, but a hanging spray bottle rack solves both problems brilliantly. These racks typically feature individual loops or slots that hold each bottle by its neck, suspending them from a mounted bar or rod. This vertical storage method frees up tons of cabinet floor space for other organizers or larger items. The bottles hang neatly in a row, making it easy to see your entire collection and grab exactly what you need. Installation usually involves mounting a simple rail or bar to the cabinet wall or utilizing a tension rod. Some versions hook over existing shelves or cabinet doors for tool-free setup. The hanging position also prevents leaks from pooling under bottles and creating sticky messes on cabinet floors. This hack is perfect for moms who have multiple cleaning solutions for different surfaces and want quick access to the right product without digging through clutter.
I love that this comes with four hooks, so you can finally clear out that cluttered cabinet!
Expandable Pipe Organizers
Those pesky pipes under the sink don’t have to steal all your storage space—expandable pipe organizers work around them beautifully. These clever shelves are specifically designed with cutouts or adjustable panels that accommodate the plumbing, maximizing the usable area on either side and above the pipes. Most models expand horizontally to fit various cabinet widths, making them versatile for different sink configurations. The elevated platform creates storage on two levels: above the organizer shelf and below it on the cabinet floor. This is perfect for storing cleaning supplies, extra paper towels, trash bags, and other essentials while working with your existing plumbing setup. Look for sturdy metal or thick plastic construction that can support the weight of your supplies without sagging. Some versions include small drawers or baskets for additional organization. Installation is typically tool-free—just adjust to size and slide into place. This hack transforms previously wasted space into functional storage real estate.
I love that this one adjusts to fit whatever awkward under-sink space you're working with.

Over-Door Hanging Pouches
Over-door hanging pouches bring organizational magic typically reserved for closets straight to your under-sink cabinets. These fabric or clear plastic organizers hang from the top of the cabinet door and feature multiple pockets in various sizes. They’re fantastic for storing smaller items that tend to get lost in bins—think sponges, steel wool pads, cleaning gloves, small scrub brushes, or travel-size products. In bathroom cabinets, they’re perfect for makeup, hair accessories, or skincare samples. The clear pocket versions let you see everything at a glance, while fabric options can match your decor. Installation couldn’t be easier—just hook over the door edge, no tools required. This hack is especially valuable for renters who can’t make permanent modifications. Make sure to measure the clearance between your door and the items stored in the main cabinet to ensure the door closes properly. Use the top pockets for lightweight items and bottom pockets for heavier supplies to prevent sagging.
I love that the padded hooks won't scratch your cabinet doors while holding all your stuff.
Narrow Pull-Out Basket
Those slim gaps beside your pipes or along cabinet edges are perfect for narrow pull-out baskets. These slender organizers are typically only three to six inches wide but can hold a surprising amount of supplies. They slide out smoothly on rails or glides, bringing hidden items into view without any awkward reaching. Use them for storing dish brushes, sponges, cleaning cloths, or tall skinny bottles that don’t fit well in wider organizers. The pull-out feature means you can utilize the full depth of your cabinet without losing track of what’s in back. Some models come with multiple tiers or compartments for additional organization. Installation varies from simple drop-in styles to mounted rail systems—choose based on your DIY comfort level. These baskets are especially brilliant for maximizing every inch in smaller cabinets where space is at a premium. The narrow profile means they can fit in spots you never thought were usable, turning wasted gaps into functional storage.
I love that the perforated plastic won't trap moisture, so it's perfect for steamy bathrooms.
Suction Cup Hooks
Suction cup hooks are the unsung heroes of under-sink organization, providing instant hanging storage without any damage to surfaces. Attach them to the inside walls or back of your cabinet to hang spray bottles, dish gloves, small brushes, or even measuring cups. The key is using heavy-duty suction hooks designed for textured surfaces, as standard ones may not grip well on all cabinet materials. Clean the surface thoroughly before applying for maximum hold. These hooks are perfect for items you use daily and want within immediate reach. In bathroom cabinets, hang hair tools, loofahs, or small towels. The removable nature means you can reposition them as your needs change without leaving holes or marks. Use multiple hooks at different heights to create a customized hanging system. This hack is especially valuable for keeping the cabinet floor clear and preventing that jumbled pile effect that happens when everything’s tossed in together. Just remember to check the weight limits and occasionally reposition hooks to maintain strong suction.
I love that these stick right to your sink or backsplash—no drilling holes in your walls!
Stacking Cleaning Caddy
Stacking cleaning caddies take portable organization to the next level by letting you store supplies vertically when not in use. These tiered caddies feature compartments for different products and stack securely on top of each other in the cabinet. When it’s cleaning time, simply unstack them and carry what you need from room to room. This system keeps related supplies together—bathroom cleaners in one caddy, kitchen supplies in another. The portability means you’re not making multiple trips back to restock your arms with bottles. Look for caddies with comfortable handles and divided sections to prevent bottles from tipping during transport. The stacking feature maximizes vertical cabinet space while keeping everything organized by category. Some models nest together when empty, saving even more space. This hack is perfect for busy moms who need to clean efficiently and can’t waste time gathering supplies. The caddy system also makes it easy for kids or partners to help with cleaning since everything they need is already grouped together and ready to go.
Roll-Out Tray Insert
Roll-out tray inserts transform your entire under-sink cabinet into a giant drawer that glides out smoothly for complete visibility and access. These custom-fit trays install on sliding rails mounted to the cabinet floor and sides, allowing the entire platform to pull forward. No more crouching down and blindly reaching into dark corners—everything comes right to you. The tray surface keeps bottles and containers stable and organized, preventing that domino effect when you grab one item. Most models feature raised edges to contain spills and keep items from sliding off during movement. Installation requires some basic tools and measuring, but the convenience is absolutely worth the effort. Choose trays with weight ratings appropriate for your typical storage load. Some versions include built-in dividers or removable bins for additional organization. This professional-grade solution is ideal if you’re ready to invest in a permanent organizational system. It’s especially valuable for deep cabinets where reaching the back is nearly impossible without this type of mechanism.
I love that this comes in a two-pack so you can organize both sink cabinet doors at once.
Magnetic Strip Holder
Magnetic strips aren’t just for knives in the kitchen—they’re surprisingly useful for under-sink organization too! Mount a magnetic strip to the inside of your cabinet door or wall to hold metal items like scissors, tweezers, nail clippers, bobby pins, or small metal grooming tools in bathrooms. In kitchen cabinets, use them for holding steel wool pads, metal scouring pads, or even small metal measuring spoons. The magnetic hold keeps items securely in place but easily removable when needed. This hack is brilliant for those tiny items that always seem to disappear into the black hole of cabinet clutter. Installation is simple with adhesive-backed magnetic strips or screw-mounted versions for heavier items. Make sure the items you plan to store are actually magnetic—stainless steel sometimes isn’t. This organizational method keeps small essentials visible and accessible while freeing up drawer and bin space for larger supplies. It’s one of those clever solutions that makes you wonder why you didn’t think of it sooner.
I love that this one sticks magnetically to your fridge—no drilling holes or dealing with sticky adhesive!
Collapsible Fabric Bins
Collapsible fabric bins offer flexible storage that adapts to your changing needs throughout the year. These soft-sided organizers come in various sizes and colors, making them perfect for corralling everything from cleaning supplies to extra toiletries. The fabric construction is gentler on cabinet finishes than hard plastic, and many feature reinforced handles for easy lifting. When you need extra space or want to reorganize, simply collapse them flat for storage elsewhere. Look for bins with sturdy cardboard or plastic panel inserts that help them maintain shape when filled. Some versions have clear vinyl windows so you can see contents without opening them. Use different colors to designate different categories—blue for bathroom supplies, gray for kitchen items. The soft sides make them ideal for storing awkwardly shaped items that don’t fit neatly in rigid containers. Fabric bins are also machine washable, which is fantastic when spills happen. This hack combines functionality with a softer aesthetic that feels less industrial than plastic alternatives.
I love that this four-pack gives you enough bins to finally tackle multiple closets at once.
Adjustable Wire Shelves
Adjustable wire shelving systems create custom vertical storage that perfectly fits your under-sink space and supplies. These expandable shelves typically feature legs that adjust in height and width, allowing you to work around pipes and create multiple storage levels. The wire construction allows air circulation, which helps prevent moisture buildup and keeps supplies fresh. The open design also makes it easy to see everything at a glance. Most systems can be configured in various ways—single tier, double tier, or even triple tier depending on your cabinet height. The adjustable nature means you can create taller spaces for oversized bottles and shorter spaces for compact items. Look for models with coated wire that won’t rust in humid bathroom environments. Some versions include removable baskets or hooks for additional organization options. Installation is typically tool-free and can be adjusted as your storage needs evolve. This versatile hack works equally well in kitchen and bathroom cabinets, providing professional-level organization on a budget.
I love that this one expands to fit whatever awkward under-sink space you're working with.
Lidded Sorting Boxes
Lidded sorting boxes bring a clean, contained look to under-sink storage while protecting supplies from moisture and dust. These stackable containers come in various sizes and keep similar items grouped together—one for dishwasher pods, one for trash bags, another for cleaning cloths. The lids prevent spills and keep everything fresh, which is especially important for items like sponges or powder cleaners. Clear lidded boxes let you see contents immediately, while opaque versions create a uniform, streamlined appearance. The stackable design maximizes vertical space, allowing you to build upward instead of outward. Look for boxes with easy-open lids that you can operate with one hand during busy moments. Some models feature snap closures while others use hinged lids—choose based on your preference. Label each box clearly so family members can find and return items correctly. This system works beautifully for both kitchen and bathroom cabinets, creating zones for different supply categories. The contained nature also makes it easier to remove everything for periodic cabinet cleaning.
