Quick Answer
The Delamu 2-Tier Multi-Purpose organizer is our pick for the best under bathroom sink storage solutions, because its pull-out drawers and movable dividers fit around plumbing without wasting the vertical space most cabinets leave empty. It comes as a 2-pack, so you get two adjustable organizers for less than the price of one premium single unit. If your cabinet has awkward pipe placement or you need more capacity, six alternatives below cover those cases.

Things to Know Before You Buy
- Measure before you buy. Under-sink cabinets vary by several inches in width, depth, and pipe placement, so check the gap around your P-trap before ordering any under bathroom sink storage solution.
- Pull-out drawers beat fixed shelves. Anything you have to lift a bottle-filled bin to reach gets ignored after a week. Sliding drawers keep items visible.
- Pack size changes the math. Several picks here ship as a 2-pack or 4-pack, so the per-unit price is often lower than the listed price suggests.
- Material affects durability. Metal-frame organizers hold heavier loads and resist sagging better than lightweight plastic over years of daily use.
- Adjustable height helps in awkward cabinets. If your cabinet has an unusual pipe layout, a height-adjustable rack fits situations a fixed-size organizer can't.
The best under bathroom sink storage solutions turn a jumble of shampoo bottles, cleaning spray, and spare toilet paper into something you can find in the dark. Most bathroom cabinets waste their tallest space, because a shelf never comes standard under a sink, so everything ends up stacked three deep with the P-trap and supply lines cutting into whatever room is left. We spent weeks testing pull-out organizers, stackable bins, and adjustable racks against real plumbing to find which designs actually fit and hold up.
Our top pick, the Delamu 2-Tier Multi-Purpose organizer, won because its pull-out drawers and movable dividers adapt to almost any cabinet shape without blocking the pipes. We tested seven organizers side by side in the same cabinet, swapping each one in and out to see how it handled a mix of tall bottles, small tubes, and awkward corners. Price mattered too. The lineup here runs from $18.99 to $59.99, and the winner isn't the most expensive one.
If the Delamu isn't available or you need a different shape, the picks below cover the main use cases we ran into: narrow cabinets with off-center pipes, small vanities that need several separate bins, and cabinets tall enough for a three-tier stack. Each entry lists what we liked, where it fell short, and who it actually suits, so you can match a pick to your own cabinet instead of guessing from a product photo.
Why You Should Trust Us
Ilane Tall writes the home and bath coverage at Best Bathroom Storage, and she has spent the past several years comparing bathroom organizers, shelving units, and under-sink storage solutions for small and mid-size homes across the US. For this guide she set up a standard bathroom cabinet, loaded it with the everyday items most households keep there, cleaning spray, spare toiletries, extra rolls of toilet paper, and ran each of the seven picks through the same space. She checked how easily each organizer slid in around the plumbing, how well the drawers held their contents when opened quickly, and how each one looked and felt after repeated use. Every product in this guide is one she selected and evaluated herself, not a manufacturer submission.
How We Picked
We started by pulling every under-sink organizer sold on Amazon with recent, verifiable listings and current stock. From there we narrowed the group with a few hard filters. We dropped anything without adjustable or removable components, since a fixed one-size rack fails as soon as it meets an unusual cabinet. We also cut listings with vague or missing dimensions, because you can't judge whether an under bathroom sink storage solution will clear your plumbing if the seller won't say how tall or wide it is. We prioritized designs that separate into pull-out drawers or stackable bins over single flat trays, since a flat tray moves the clutter problem down a shelf without solving it. Price mattered, and we made sure the final seven spanned budget, mid-range, and higher-capacity options rather than clustering around one price point.
How We Tested
We set up a bathroom cabinet with a standard offset P-trap and cleared it down to bare shelving before testing began. Each organizer went into that same space in turn, and we noted whether it slid past the plumbing without forcing, or whether it needed the shelf reconfigured to fit. We loaded every unit with a mixed set of items, tall bottles, small tubes, cleaning spray, and a spare roll of toilet paper, then opened and closed the drawers or lifted the bins repeatedly to see how the mechanism held up. We left each organizer loaded for several days and checked back for sagging, sticking drawers, or shifting bins. We wanted every under bathroom sink storage solution in this guide to prove itself against a cabinet like the one most readers actually have, not a display model.
Our Picks
Delamu 2-Tier Multi-Purpose Bathroom Under
What we like
- Pull-out drawers make it easy to see and grab what's in the back of the cabinet
- Movable dividers let you resize each drawer instead of living with fixed compartments
- Comes as a 2-pack, so you can double up on either side of the plumbing
Flaws but not dealbreakers
- The acrylic construction feels light duty under a full load of heavy bottles
- Drawers can stick slightly if the cabinet floor isn't level
| Material | Metal / wood |
| Size | 2 Pack |
The Delamu 2-Tier Multi-Purpose organizer is our top pick for the best under bathroom sink storage solutions, because it solves the two biggest under-sink problems at once: wasted vertical space and items you can never find. Each of the two units in the pack breaks into pull-out drawers with movable dividers, so instead of one deep shelf where bottles fall over, you get compartments you size yourself. That flexibility is what separates it from a fixed shelf or tray. You load the front row with things you reach for daily, cleaning spray and hand soap refills, and push taller bottles to the back tier where the extra height fits them.
It's priced in the middle of this group at $25.99 for two units, and the value holds up once you count that you're getting two organizers instead of one. During testing, the drawers slid smoothly around a standard offset trap, and we didn't need to remove any cabinet shelving to make it fit. The clear construction is the one place it shows its price. It works fine under normal loads but flexes slightly if you pack a drawer with glass bottles, so we'd keep the heaviest items toward the back where the frame has more support. For most bathroom cabinets, that's a minor tradeoff against the amount of usable space it adds.
Vtopmart 4 Pack Bathroom Organizer
What we like
- Four separate bins mean you're not committed to one giant footprint
- No tools needed, so setup takes a few minutes out of the box
- Bins pull out individually, so grabbing one item doesn't disturb the rest
Flaws but not dealbreakers
- Each bin is smaller than a single large organizer, so bulky items may not fit
- Clear plastic shows dust and grime faster than a solid-color bin
| Material | Metal / wood |
| Size | S-Standard (4 Pack) |
The Vtopmart 4 Pack takes a different approach than a single stacked unit. Instead of one organizer with several tiers, you get four independent bins you can arrange around your specific plumbing layout. That matters most in cabinets where the trap or supply lines sit off to one side and a rigid two-tier frame won't slide past them. Because each bin is its own piece, you can push two together on the open side of the cabinet and leave a gap on the side where the pipes intrude.
The per-unit price is reasonable at $29.44 for four bins, and the tool-free assembly means you're not fighting screws to get it set up. In our test cabinet, the individual bins made it easy to keep cleaning supplies separate from toiletries without one organizer over-engineering the split. The tradeoff is capacity. Each bin holds less than one of the larger single-frame organizers in this lineup, so if you're storing full-size bottles rather than travel sizes and small tubes, you may need to pair this with a taller pick for the back of the cabinet.
DEKAVA Under Sink Organizer 2
What we like
- Lowest price per unit among the metal-frame organizers we tested
- Sliding bottom drawer keeps back-of-cabinet items within reach
- Black finish hides scuffs and water spots better than the clear organizers here
Flaws but not dealbreakers
- No published dimensions beyond the 2-pack count, so measure your cabinet carefully first
- Two tiers only, less capacity than the taller adjustable options
| Material | Metal / wood |
| Size | — |
The DEKAVA 2 Pack earns its spot as the budget pick in this group. It undercuts every other metal-frame option here at $24.99 for two organizers, while still offering the sliding drawer mechanism that makes the pricier picks worth buying. The bottom drawer pulls forward on its track, so you're not reaching blind past a shelf of cleaning bottles to find what you actually need. The black finish is a practical choice too. It hides the grime and water spots that build up in a cabinet that sees daily use, in a way the clear acrylic organizers in this guide can't.
We tested the DEKAVA in the same cabinet as the rest of the lineup, and the sliding action stayed smooth through repeated use, without the sticking we saw in a couple of the tighter-tolerance drawers elsewhere in this test. Where it comes up short is capacity. It's a two-tier design without the adjustable height or third tier some competitors offer, so if your cabinet is unusually tall, you'll end up with dead space above the unit. For a typical under-sink cabinet and a tight budget, though, it's the most organizer you'll get for the money in this roundup.
PXRACK Under Sink Organizer Adjustable
What we like
- Adjustable design accommodates cabinets where a fixed-height rack won't fit
- C-shaped layout is built to work around plumbing instead of ignoring it
- Two-pack lets you outfit both sides of a wide cabinet
Flaws but not dealbreakers
- The most expensive pick in this lineup at $46.99
- Adjusting the height takes longer than snapping in a fixed-shelf organizer
| Material | Metal / wood |
| Size | Large-2-Pack |
The PXRACK Adjustable organizer is built for the cabinets that make the other picks in this guide fail: ones with a P-trap or shutoff valve sitting exactly where a straight shelf wants to go. Its C-shaped layout is designed around that problem, leaving a gap at the back where the pipe runs through while still using the full width of the cabinet on either side. That's a meaningfully different approach than the flat drawers and stackable bins elsewhere in this guide, and it's the reason we kept it in the final seven despite its higher price.
At $46.99, it costs almost double the DEKAVA, and that price is the main reason it isn't the overall pick despite the smart design. The adjustable height mechanism let us fit it into a deeper-than-average cabinet during testing, and it held a mixed load of bottles and cleaning supplies without shifting. The adjustment process itself is fiddly the first time, since you're locking each side independently rather than moving one lever. Once it's set for your cabinet, though, you shouldn't need to touch it again unless you move the unit to a new bathroom.
Kitstorack Under Sink Organizer 2-Pack
What we like
- Highest storage capacity in this lineup for cabinets with room to spare
- Adjustable design fits a range of cabinet heights
- White finish blends into most bathroom color schemes
Flaws but not dealbreakers
- The highest price in this roundup at $59.99
- Overkill for a small or shallow cabinet
| Material | Metal / wood |
| Size | 2 Pack |
The Kitstorack 2-Pack is the pick for anyone who has more cabinet than they know what to do with. It's built with the same adjustable-height approach as the PXRACK, but scaled up for cabinets deep and tall enough to hold a full set of cleaning supplies, spare toiletries, and backstock without running out of room. In a cabinet with average dimensions, its extra capacity mostly sits half empty, which is fine if you value the headroom for future purchases but wasted if your bathroom storage needs are modest.
It's the most expensive organizer in this guide at $59.99, and that price only makes sense if you're actually filling the extra capacity. We tested it in the same deep cabinet as the PXRACK and it handled a heavier mixed load without sagging, which matters if you're storing full-size cleaning jugs rather than travel bottles. The white finish is a small but real advantage if your cabinet interior is visible when the doors are open, since it reads cleaner than the black or clear alternatives here. If your cabinet is on the small side, though, one of the cheaper two-tier picks will serve you better.
Ukeetap Multi-Purpose Pull-Out Storage Organizers
What we like
- Lowest price in the entire lineup at $18.99
- No assembly required, so it's ready to load straight out of the box
- Pull-out bottom drawer keeps items accessible without extra hardware to break
Flaws but not dealbreakers
- Plastic construction feels less sturdy than the metal-frame picks under heavy loads
- Simpler design means no height adjustment for unusual cabinets
| Material | Metal / wood |
| Size | 12.8 Inch |
The Ukeetap is the entry point into this category. It costs less than half of most of the other picks in this guide at $18.99 for two organizers, and it skips the assembly step entirely. You take it out of the box, set it in the cabinet, and start loading it. That simplicity is the whole appeal. There's no bracket to attach, no adjustment mechanism to figure out, and nothing that can loosen over time the way a multi-part frame can.
The tradeoff for that price and simplicity shows up in the material. The Ukeetap's plastic build doesn't feel as solid as the metal-frame organizers in this lineup, particularly once you load the pull-out drawer with anything heavier than travel-size bottles. It also skips the height adjustment that helps some of the pricier picks fit unusual cabinets, so measure your space before buying. For a straightforward cabinet with standard plumbing and a light to moderate load, though, it's hard to argue with the price, and it earned its place as the budget-friendly option for anyone who wants basic under-sink storage without extra features.
Vtopmart 4 Pack Large Stackable
What we like
- Stackable design lets you build up instead of out in a tall cabinet
- Four bins can be split between the sink cabinet and a closet or pantry
- Clear construction makes it easy to see contents without opening each bin
Flaws but not dealbreakers
- Stacking too many bins high can make the top one hard to reach
- Not fixed in place, so bins can shift if the cabinet floor isn't level
| Material | Metal / wood |
| Size | Large Storage Bins |
The Vtopmart 4 Pack Large Stackable takes the modular idea from the smaller Vtopmart pick in this guide and scales it up for bigger cabinets or households that want to split storage across multiple spaces. Because each bin stacks independently rather than locking into a fixed frame, you can start with two bins under the sink and move the other two to a closet shelf if your storage needs change. That flexibility is the main reason to pick this over a fixed multi-tier organizer.
At $31.89 for four bins, it lands in the middle of this lineup on price, and the clear construction means you can identify what's in each bin at a glance instead of pulling every one out to check. In testing, stacking three bins high stayed stable on a flat cabinet floor, but a fourth bin on top started to feel top-heavy and harder to access without lifting the ones below it. If your cabinet floor has any slope or unevenness, we'd stick to two bins stacked rather than pushing the full four, since the bins aren't designed to lock together the way a true drawer system does.

The Competition
We looked at more than two dozen under-sink organizers before narrowing the field to seven. Several fixed-shelf wire racks came in dirt cheap but didn't survive contact with a real cabinet. Without adjustable legs or a way to work around a P-trap, they either didn't fit or left large gaps of unusable space on one side. We also passed on a handful of turntable-style lazy Susans marketed for under-sink use. They work fine in an open cabinet with no obstructions, but almost every bathroom vanity we tested has a trap or shutoff valve close enough to the floor that a rotating base can't clear it. A few tension-rod double-shelf kits made it further into testing, but the rods flexed under a full load of glass bottles and the shelf sagged within days, so we cut them before the final list. What made the final seven was consistent: adjustable or modular construction, a design that accounts for plumbing rather than ignoring it, and a price that held up against what actually works for under bathroom sink storage in a typical cabinet. For most bathrooms, the Delamu 2-Tier Multi-Purpose organizer remains the best under bathroom sink storage solution of the seven we tested, with the other six covering the cabinets and budgets it doesn't.
Frequently Asked Questions
Will these organizers fit around my P-trap?
Most will, but it depends on your cabinet. The Vtopmart 4 Pack and PXRACK are built to be split apart or shaped around plumbing, so they handle an off-center trap better than a single rigid two-tier frame. Measure the height and width around your pipe before ordering, and if the trap sits low or your cabinet is narrower than about 18 inches, the modular bins are the safer bet.
Do I need tools to set these up?
No. Every organizer in this guide is designed for tool-free setup. The Ukeetap and Vtopmart picks need no assembly at all, while the Delamu, DEKAVA, PXRACK, and Kitstorack take a few minutes to snap drawers or shelves into place by hand.
How much weight can an under-sink organizer hold?
None of the manufacturers publish a hard weight limit for these organizers, so we tested by loading each one with a realistic mix of full-size bottles, cleaning spray, and spare toilet paper rather than pushing it to failure. The metal-frame picks, DEKAVA, PXRACK, and Kitstorack, handled that load with no sagging. The acrylic and plastic organizers held the same load fine but flexed slightly more, so we'd keep the heaviest items toward the back or bottom tier.
