Stacked Laundry Setup Short on Space? 12 Costco Organizers Under $80

A closet-sized stacked washer and dryer leaves little room for a storage fantasy, especially when the usable side bay is only about 14.5 inches wide. Costco’s best options are compact open-front bins, a shallow steel rack, or a rolling cart that can actually clear the door.

We measured these choices by footprint, access, and the kind of laundry supplies they can hold. The right organizer should make the next load easier without turning the appliance closet into another obstacle.

Measure the Side Bay Before Shopping

Start with the usable opening beside the stacked washer and dryer, then measure from the floor to the lowest obstruction. The Oceanstar cart is about 14.5 inches wide, while the TRINITY unit is about 23 inches wide, so neither belongs in a five-inch appliance gap.

Include door trim, baseboards, hinges, and the cart’s rolling path in the measurement. A narrow closet rewards accurate planning because one extra inch can decide whether a product is useful or permanently stuck.

Fill an Existing Shelf with Clearly Bins

The Clearly Open Front Closet Storage Bin, Costco item 1958115, is the best choice when floor space has already disappeared. Costco lists each clear storage bin at 10 by 16 by 6 inches, making it practical for an existing shelf beside the appliance stack.

Use one bin for cleaning cloths and dryer balls, then keep garment bags and small accessories in another. The open front earns its place because you can grab supplies without removing a lid or pulling down a heavy container.

Pair Two Bins Across One Shelf

Two Clearly bins create a footprint of about 20 inches wide by 16 inches deep, so check the shelf before ordering the two-pack. That arrangement gives each category a defined home without consuming the closet floor.

At about $22 for a two-pack, the Clearly bins are the most approachable Costco benchmark in this group. They are worth choosing over decorative baskets when visibility and quick access matter more than hiding every label.

Keep Open Fronts at Reach Height

Place the bin opening between waist and shoulder height whenever possible, especially for detergent accessories used every week. A shelf that requires a step stool turns a simple storage idea into an irritating chore.

The rigid construction of the Clearly open-front design also keeps soft items from collapsing into a messy pile. Store lightweight supplies there, and leave bulky detergent containers on a lower, sturdier surface.

Build Up with a TRINITY Rack

For a genuinely wider laundry closet, the TRINITY 3-tier Modular Wire Shelving Rack provides vertical storage without wrapping around the appliance stack. Each unit is about 23 inches wide by 13 inches deep by 30 inches high, with steel wire shelves and a chrome, black, or bronze finish.

The TRINITY steel rack can also be combined into a configuration about 60 inches high, according to the manufacturer-approved setup. Its shallow depth is useful, but the 23-inch width makes it a side-bay solution rather than a skinny gap filler.

Reserve the TRINITY for a Side Bay

Place the TRINITY rack in a separate side bay where its full width can remain accessible. Keep the lowest shelf for heavier bottles, the middle shelf for fabric-care supplies, and the upper shelf for backup items used less often.

Budget roughly $50 to $65 for the two-pack, depending on the Costco selling price. This wire shelving rack is the strongest choice when you need capacity and can spare real floor width.

Roll an Oceanstar Cart into Position

The Oceanstar 3-tier Storage Cart works when the side bay is wider than 14.5 inches and has a clear route to the closet door. Its overall footprint is about 14.5 by 18.5 by 31.5 inches, so measure both the parking space and the path in front of it.

With removable bamboo trays in a black metal frame, the Oceanstar cart makes supplies easier to bring forward. It is listed as online-only at Costco, and about $80 is a reasonable shopping benchmark rather than a guaranteed local checkout price.

Assign Each Bamboo Tray a Job

Use the Oceanstar’s three removable trays by task: stain treatment on one, garment-care accessories on another, and spare cloths on the third. This keeps the cart functional when it is rolled beside the stack instead of forcing every item into one crowded basket.

The bamboo trays add warmth to a utility space, but the cart still needs a clear floor. Choose this setup for convenience and mobility, not for a narrow gap that barely accepts its frame.

Store Fabric-Care Tools Together

Group dryer balls, mesh bags, stain brushes, and small cloths in one accessible zone rather than scattering them around the closet. A Clearly bin or one Oceanstar tray can hold these lightweight items without competing with detergent bottles.

The dryer balls should stay easy to see because they disappear quickly when buried behind larger supplies. This category is small enough for open-front storage and does not need a deep cabinet.

Give Garment Bags Their Own Bin

Garment bags bend and snag when they share a crowded shelf with bottles, so give them a dedicated Clearly bin. The six-inch height of the rigid clear bin keeps folded bags contained while leaving the front open for quick retrieval.

Place the bin on an existing shelf beside the stack, not on top of the appliances. The goal is a visible accessory station that stays within reach and does not interfere with ventilation, doors, or controls.

Keep Heavy Bottles on Steel

Use the lower level of the TRINITY rack for detergent, softener, and other heavy containers. Steel wire shelving is a better match for that load than a lightweight decorative basket or a shallow plastic organizer.

Leave enough room to lift each bottle straight up without scraping the shelf above. The black steel shelving also makes a clear visual boundary between heavy backup products and the small items stored in bins.

Leave the Appliance Stack Uncrowded

Storage should sit beside the washer and dryer, on an existing shelf, or in a separate side bay with access around the doors and controls. Avoid leaning a cart against the appliances or placing bins where they can vibrate into hoses and cords.

A closet-sized setup works best when the stacked washer and dryer remains the visual and functional anchor. Costco’s bins, rack, and cart solve different space problems, so choose one layout instead of forcing all three into the same tight footprint.
