Clear Stackable Under-Sink Bathroom Organizer | Stackable Bins for Grooming Tools, Tall Shampoo & Conditioner Bottles, and Cleaning Supplies

Stack. Separate. See Everything. Finally Have an Under-Sink Bathroom Cabinet That Makes Sense.

The trimmer tangled with the razor. Shampoo and conditioner bottles tipped over on the cabinet floor. Cotton swabs loose next to the toilet cleaner. Cleaning gloves mixed in with the toothbrush heads. Mouthwash rolling around behind the spray bottle. The bathroom under-sink cabinet handles more categories of items than any other storage space in the home — grooming tools, personal care, skincare refills, and cleaning supplies — and without a system, everything ends up in one undifferentiated pile. The KairoHubs Clear Stackable Under-Sink Bathroom Organizer gives you a simple, no-drill solution: stack two clear bins on top of each other to double your vertical storage, separate each category into its own bin, and see every item at a glance through clear walls on all four sides. The built-in side handles let you slide any bin out like a drawer for full access without moving the stack above it. No shelves to install. No permanent hardware. Just a system that works around the drain pipe and uses the space you already have.

Before & After — Real Bathroom Under-Sink Transformation

Before: hair trimmer and Gillette razor loose on the cabinet floor, razor blade refills mixed in with cotton swabs, shampoo and conditioner bottles tipped sideways, blue mouthwash rolling next to the toilet bowl cleaner spray, yellow sponges and teal rubber gloves piled in the corner, microfiber cloths unfolded under everything else — three different categories of items in one unnavigable heap. After: trimmer, razor, and blade cartridges in the bottom grooming bin; tall shampoo, conditioner, body wash, mouthwash, and face wash bottles standing upright in the top bottle bin; spray bottles, sponges, gloves, microfiber cloths, and scrub brush in their own stacked cleaning bin — every category separated, every item visible, every bin accessible by sliding it out. Grooming tools below, tall bottles above. Cleaning supplies on their own stack. Full product measurement details available in images.

3 Stacks That Cover Every Bathroom Under-Sink Category

Stack 1 — Grooming Tools (Top) + Grooming Accessories (Bottom)
Upper bin holds tall grooming items — electric trimmer, corded shaver, beard brush — upright and visible. Lower bin holds the smaller grooming accessories: Gillette razor, blade cartridge refills, nail clippers, cuticle scissors, cotton swab jar, cotton pad container, shaving cream tube, and spare toothbrush heads. Every grooming tool separated from every personal care product. No more digging for a razor buried under a shampoo bottle.

Stack 2 — Tall Bottles (Top) + Skincare & Personal Care Refills (Bottom)
Upper bin stands up every tall bottle: shampoo, conditioner, body wash, mouthwash, face wash, toner, and hair serum. Wide enough for pump bottles and squeeze tubes side by side. Lower bin holds everything shorter: travel-size skincare products, spare soap bars, sunscreen tubes, deodorant refills, dry shampoo cans, and backup personal care items bought in bulk. Stack them in the same footprint and you’ve doubled the usable height of that side of the cabinet.

Stack 3 — Cleaning Supplies (Top) + Scrubbing Tools & Rags (Bottom)
Upper bin holds the tall cleaning bottles: toilet bowl cleaner spray, blue glass cleaner, bathroom surface spray, and refill bottles. Lower bin holds the scrubbing and wiping tools: yellow sponges, teal and blue rubber gloves, microfiber cloths, scrub brush, toilet brush refills, and drain cleaning tabs. Every cleaning supply visible, nothing mixed in with the grooming or personal care bins.

Key Features

• Stackable Design — Double Your Vertical Storage — bins stack directly on top of each other with a stable flat base; two bins in the same footprint use the vertical cabinet space above the drain pipe that would otherwise go to waste; fits the natural height of a standard bathroom under-sink cabinet
• Clear Walls on All Four Sides — see the trimmer, the razor, the shampoo level, and the remaining sponge supply without opening the cabinet or pulling anything out; no guessing what’s in the back of the bin
• Built-In Side Handles — slide any bin out independently for full access; pull the bottom grooming bin without disturbing the tall bottle bin stacked above it; works like a drawer without requiring any installation
• Tall Enough for Full-Size Bottles — upper bin height accommodates full-size shampoo, conditioner, body wash, and mouthwash bottles standing upright; no laying bottles on their side and hoping the cap holds
• Compact Footprint — Fits Beside the Drain Pipe — rectangular base fits on either side of the drain pipe in standard bathroom under-sink cabinets; line two stacks side by side for a complete four-bin organization system
• Flat Ridged Base — ribbed interior base keeps bottles and tools from sliding during access; elevated feet keep the bin level on cabinet floors and allow air circulation underneath
• Open Top Design — no lid to unlatch; drop items in and grab them out one-handed during a morning grooming routine or mid-clean
• Smoke-Tinted Clear Finish — semi-transparent look that keeps contents visible while giving the cabinet a cleaner, more intentional aesthetic than opaque bins
• No Drill, No Hardware — no mounting, no shelf installation, no tools required; stack the bins, place them in the cabinet, and the system is set up

Frequently Asked Questions

Q: Will full-size shampoo and conditioner bottles fit upright?
A: Yes — the upper bin is tall enough to hold full-size shampoo, conditioner, body wash, and mouthwash bottles standing upright. Full dimensions are in the product images.

Q: Can I pull the bottom bin out without moving the top one?
A: Yes — the built-in side handles let you slide each bin out independently. Pull the lower grooming bin without disturbing the tall bottle bin stacked on top.

Q: Will it fit beside the drain pipe?
A: The rectangular footprint is designed to fit on either side of the drain pipe in a standard bathroom under-sink cabinet. Measure your available cabinet width and compare to the product dimensions in the images before purchasing.

Q: Do I need to install anything?
A: No — no drilling, no mounting hardware, no tools required. Stack the bins, place them in the cabinet, and the system is ready.

Q: Is the tint opaque or can I still see what’s inside?
A: The bins are semi-transparent with a light smoke tint — contents are clearly visible from the front and sides at a glance.

Q: Can these also be used in the kitchen under-sink or pantry?
A: Yes — the same stackable system works equally well for kitchen cleaning supplies, pantry dry goods, and under-sink kitchen organization. Designed for multi-room use.
