At first glance, that skinny vertical pull-out cabinet next to your dishwasher might seem completely pointless—like a weird leftover space that serves no real function. You might even think it’s a design flaw or just a waste of valuable kitchen real estate. But hold that thought, because what seems like a useless gap is actually one of the smartest, most underrated tools in a modern kitchen.

That narrow sliding drawer is called a cabinet filler pull-out, and it’s designed to transform even the smallest sliver of space into efficient, practical storage. Typically measuring between three to six inches wide, these pull-outs are built to slide open smoothly and store all kinds of kitchen essentials that usually end up getting lost in larger drawers or cluttered cabinets. They’re often found tucked between appliances or squeezed into spots that wouldn’t accommodate a regular-sized cabinet. Instead of letting that small gap between your dishwasher and the wall go to waste, this little pull-out turns it into high-function storage that’s both accessible and space-saving. It’s a game-changer, especially in kitchens where every inch counts.

Think about how frustrating it is to dig through a packed drawer looking for a spice bottle, or how annoying it is when your cutting boards keep tipping over in a cabinet. A filler pull-out solves those problems effortlessly. When located beside the dishwasher, the options get even better. You can use it to store dishwashing pods, rinse aid, sponges, or rolled towels—all right next to where you need them. You can even hang cleaning cloths or rags if you install a simple bar or hook inside. If you’re constantly reaching for certain seasonings while cooking, this spot makes the perfect spice rack. Line up salt, pepper, garlic powder, or anything you use frequently. It’s quick, tidy, and always at arm’s reach. For utensils that are too long or oddly shaped for traditional drawers—think ladles, tongs, or spatulas—you can set up a vertical caddy inside the pull-out to hold them upright and organized.

Got reusable water bottles or travel mugs? Stand them up in this space for easy access and quick drying. You can also turn it into a station for plastic wrap, foil, or parchment paper, keeping them stored upright so they’re easy to grab without creating clutter. Another creative use is storing small cleaning tools like brushes, scrubbers, and extra sponges—perfectly hidden but close to the sink. If you’re a pet owner, use it to stash food bowls or mats that you wash regularly. Or, slide in a mini recycling or compost bin for scraps and wrappers to make clean-up more efficient. What’s surprising is how many people assume these pull-outs are luxury add-ons found only in high-end kitchens. In reality, they’re available in a wide range of price points and many even come pre-assembled for easy installation.

You don’t need a full kitchen remodel to enjoy their benefits—just a few inches of unused space and the willingness to make it work harder for you. The beauty of these pull-outs is in their customizability. You can tailor the interior with adjustable shelves, dividers, hooks, and bins depending on what you want to store. Instead of tossing in random items and calling it a day, take a minute to organize with intention. Place taller items on the bottom, smaller containers up top, and use slide-in trays or racks to keep everything upright and tidy. Today’s kitchens are expected to do more than ever—they’re not just places to cook, but often serve as family hangouts, makeshift offices, or homework stations. That means we need to make them smarter, not necessarily bigger. Optimizing space helps keep things organized, reduces stress during meal prep, and improves the overall flow of your daily routine. That unassuming skinny drawer you once dismissed might end up being the most functional cabinet in your entire kitchen. So the next time you see one and wonder, “What’s the point?”—just remember, it’s not a waste. It’s a small-space superhero in disguise.
