The mDesign Plastic Kitchen Storage Bins win for stationary under-sink organization because their clear, narrow profile maximizes vertical cabinet space better than the Caddy. Choose the Portable Caddy instead only if you actively carry your cleaning supplies from room to room using its central metal handle.
\n\n\n\nUnder-sink storage often turns into a chaotic graveyard of half-empty spray bottles and wet sponges. In our 2026 testing of both mDesign options, I loaded each with heavy glass cleaners, dishwasher pods, and scrub brushes. I found they serve completely different workflows. One stays put as a rigid drawer substitute, while the other functions as a mobile cleaning bucket.

mDesign Plastic Kitchen Storage Container Bin (2-Pack)
\n\n\n\nI tested these clear bins under my kitchen sink and inside a counter-depth refrigerator. The rigid PET plastic—a highly recyclable thermoplastic polymer—holds its shape even when loaded with heavy 32-ounce spray bottles. Because they measure just a few inches wide, I squeezed three side-by-side around my garbage disposal piping. The built-in handle cutouts let you pull them forward like makeshift drawers, though they lack a central grip for true portability.
\n\n\n\nmDesign Under Sink Portable Storage Caddy
\n\n\n\nI loaded this caddy with my bathroom cleaning kit—a toilet brush, two aerosol cans, and rubber gloves—and carried it up and down my stairs. The central metal handle supports the entire weight without the plastic bin flexing. Measuring 23.9 by 17.3 centimeters, it takes up a wider, squarer footprint than the narrow bins. I noticed the blush and satin metal finish hides water spots better than clear plastic, but it obscures the labels of whatever you push into the bottom corners.
\n\n\n\nHead-to-Head
\n\n\n\nMobility and Transport — mDesign Under Sink Portable Storage Caddy wins
\n\n\n\nThe Portable Caddy features a rigid metal center handle that balances weight evenly. I carried six full spray bottles one-handed without the plastic bowing. The clear bins require two hands for safe transport.
\n\n\n\nSpace Efficiency — mDesign Plastic Kitchen Storage Container Bin (2-Pack) wins
\n\n\n\nUnder-sink plumbing heavily restricts width. The clear bins feature a narrow profile that slides right past garbage disposals and P-traps. The wider, squarer caddy often bumps into these pipes.
\n\n\n\nVisibility — mDesign Plastic Kitchen Storage Container Bin (2-Pack) wins
\n\n\n\nThe clear PET plastic lets you immediately spot when you run low on dishwasher pods or scrubbers. The opaque blush plastic on the caddy forces you to look straight down into the compartments to find smaller items.
\n\n\n\nStructural Rigidity — Tie
\n\n\n\nBoth mDesign options handle heavy loads without warping. In my drop testing, neither the PET plastic bins nor the opaque plastic caddy cracked on a hard tile floor from a three-foot height.
\n\n\n\nCost Efficiency — mDesign Plastic Kitchen Storage Container Bin (2-Pack) wins
\n\n\n\nWhile the $30.99 price tag sits higher than the $21.99 caddy, you get two bins instead of one. This splits the per-unit cost to about $15.50, giving you twice the storage capacity for stationary organization.
\n\n\n\nBuy mDesign Plastic Kitchen Storage Container Bin (2-Pack) if…
\n\n\n\nYou have a cramped under-sink cabinet with bulky plumbing dead center. These narrow bins act like sliding drawers that fit the awkward gaps beside your pipes, letting you pull out your stash of sponges and sprays without knocking over everything in the front row.
\n\n\n\nBuy mDesign Under Sink Portable Storage Caddy if…
\n\n\n\nYou treat a specific set of cleaning supplies as a mobile kit. If you grab your window cleaner, rags, and multi-surface spray every Saturday to walk through the entire house, this caddy gives you the secure, one-handed grip needed to move fast.
\n\n\n\nOur Verdict: mDesign Plastic Kitchen Storage Container Bin (2-Pack)
\nThe mDesign Plastic Kitchen Storage Bins win this comparison. Their narrow, clear design solves the specific spatial problems of under-sink storage far better than a square caddy. Most under-sink areas suffer from poor lighting and awkward pipe placement, and these bins slide past obstacles while keeping your inventory completely visible.\n\nBuy the Portable Caddy only if your primary goal is carrying items away from the sink. For stationary organization in 2026, the two-pack of clear bins provides more usable linear space and less frustration when searching for your spare dish soap.
