15 Under-Sink Organizers for Bathrooms That Fit Around the Pipes
A bathroom vanity cabinet is a tight box with plumbing in the middle of it. The trap sits higher and closer to the door than in a kitchen cabinet, and supply lines run down the back wall.
The best under-sink organizers for bathrooms are the ones sized for that box. This list states the height, width and depth of every pick, so you can measure first and rule out the ones that cannot fit.
Three measurements decide almost every fit. Measure from the cabinet floor to the lowest point of the trap. Measure the clear width on each side of the trap. Then measure the door opening the organizer has to pass through.
The 15 picks cover sliding tiers, stackable drawers, a cabinet built for pedestal sinks, a turntable and two mats. For a wider kitchen base cabinet, our guide to pull-out under-sink organizers covers that space instead.
Two picks are mats, and they work as the base layer under the bins and drawers from the other picks.

1. Yamazaki Home Two-Tier Cabinet Storage Basket — Two narrow pull-out baskets for the strip beside the trap
Start with the height, because it decides this pick. At 18.11 inches tall, this is the tallest organizer in the article. It suits tall vanity cabinets and the space beside a high trap, and nothing lower.
The manufacturer lists the full size as 12.8 inches long, 6.3 inches wide and 18.11 inches high. The two pull-out baskets are ABS plastic, and each one measures 6 by 12.6 by 4.8 inches in the manufacturer’s data.
The listed load is 13.2 lb per tier, and the unit weighs 5.07 lb. It comes in White (5218) and Black (5219). Watch for that height: measure floor to trap before you consider it.
2. DEKAVA Under Sink Organizer, 2-Pack — Two sliding two-tier units, one for each side of the trap
This 2-pack comes from the brand’s Bath Collection, and the pair is the point. Each unit is 8 inches wide, so one sits on each side of a centered trap in a standard vanity.
Each organizer measures 15 inches deep, 8 inches wide and 13 inches high, model ORGER-2. The baskets are ABS plastic on steel tubes. The bottom drawer slides out, so the back row stays reachable.
The listing states the bottom area holds items up to 10.3 inches high, which is the bottle clearance to check against your shelves. Watch for the 13-inch total height: a low trap rules this pair out.
3. Petiza Under Sink Organizer, XL 2-Tier Adjustable Height — L-shaped drawers with seven height settings
The L shape is the pipe dodge here. The top basket is narrow at 14 by 6.3 inches, while the bottom basket is wider at 15.16 by 8.66 inches, so bottles sit low and the tier steps around the trap.
Assembled, the listing gives 14.95 by 9.65 by 15.75 inches. Both drawers slide on an industrial ball-slide design, and they can be installed on the left or the right side of the cabinet.
The bottom area holds bottles up to 10.8 inches high, and the drawer height adjusts through seven settings. Watch for the range: the listing does not publish the lowest setting, so check your trap clearance first.
4. Fabspace Pull-Out Home Organizer, 3-Pack 2-Tier Clear with Dividers — Three small clear units that split around the trap
Each unit in this 3-pack measures 11.8 by 7 by 10.6 inches, model MPNSH0001-P3. At 7 inches wide and 10.6 inches tall, one unit clears a bathroom trap that a taller kitchen organizer cannot.
The organizers are clear plastic, they pull out, and they come with dividers. The listing also describes them as stackable. The brand sells them for vanity counters and cabinets as well as under-sink use.
The 3-pack splits across both sides of the trap, with the third unit on a linen shelf or in a second vanity. Watch for the tier height: tall pump bottles will stand outside these units, not inside them.
5. STORi Audrey Stackable Organizer Drawers, 6.75-Inch Tall, Set of 2 — Clear drawers that stack or sit side by side
One drawer in this set measures 6 inches wide, 7.88 inches long and 6.75 inches high. The set holds two clear plastic drawers, and the listing states they are made in the USA.
The drawers can be used side by side or stacked, so the layout follows the space you actually have. Stacked, the pair takes one side of the trap and leaves the other side open for tall bottles.
The brand positions the Audrey collection for bathroom cabinets and vanities, and names hair accessories, cotton balls and medicine as under-sink uses. Watch for the depth: at 7.88 inches, long bottles lie down or stand elsewhere.
6. kleankin Pedestal Sink Storage Cabinet with U-Shape Cut-Out — A freestanding cabinet for a sink with no cabinet
This pick is furniture, not an in-cabinet organizer. It is a freestanding cabinet in MDF board, model 834-279WT, built for pedestal sinks. The U-shaped cut-out slots around the pedestal and the pipes behind it.
Overall it measures 23.5 inches wide, 11.75 inches deep and 23.5 inches high. The internal shelf adjusts, with an inner shelf size of 19.5 by 10.5 inches, 8.75 inches high above and 10.25 inches below.
That gives a pedestal sink the closed storage it never had, for toiletries and cleaning bottles. Watch for fit: the retailer states to measure before purchasing, because pedestal widths and pipe positions vary from sink to sink.
7. GEMWON Expandable Under Sink Organizer with Removable ABS Panels — A two-tier shelf you rebuild around your own pipe
The top surface of this shelf is built from 8 removable ABS panels, each 11 by 6.3 inches. Panels lift out where your drain pipe runs, so the shelf takes the shape of your plumbing instead of a fixed outline.
The length expands from 16.5 to 30.7 inches on telescopic rails. Height runs from about 13.19 inches to 16.73 inches, set by screw holes on the U-shaped support tubes. The frame is metal, model USS02.
The box holds 4 extension rails, 2 H-shaped and 2 U-shaped tubes, 12 locking screws and wrenches. Watch for the side width: it is fixed at about 11.2 inches, and that depth cannot shrink.
8. Yamazaki Home Three-Tier Cabinet Storage Rack, 14-Inch Steel — Three steel shelves with heights that adjust by the inch
Yamazaki Home names bathroom cabinets directly for this steel rack, model 2011 in White. The manufacturer lists it at 16.34 inches long, 12.99 inches wide and 13.58 inches high, just under its 14-inch name.
Shelf heights adjust at 1-inch increments, per the manufacturer’s data, so the levels can be set around a trap instead of arriving at one fixed spacing. The inner shelf dimension is 15.75 by 12.2 inches.
The stated capacity is 22 lb per shelf, with a small hook rated at 0.55 lb. Watch for the width: at 12.99 inches, this is a one-side-of-the-cabinet pick in most vanities, not a full-width one.
9. simplehuman 9-Inch Pull-Out Cabinet Organizer — A low steel frame that slides out under the trap
At 6 inches high, this frame works in the low, clear zone under a trap where a two-tier rack cannot go. The manufacturer’s drawing gives 20.0 inches deep, 9.0 inches wide and 6.0 inches high, model KT1118.
The frame is heavy-gauge steel and holds up to 20 lb, per the manufacturer. It runs on pre-aligned, commercial-grade ball-bearing tracks. A removable drip guard sits in the frame to catch spills from bottles.
At 9 inches wide it leaves the rest of the cabinet for bins. Watch for two things: the 20-inch depth is long for shallow vanities, and the tracks fix into the cabinet rather than dropping in.
10. Joseph Joseph CupboardStore Easy-Access Wheeled Storage Caddy — A long caddy on wheels for bottles beside the trap
This caddy rolls instead of sliding on rails. It measures 4.4 inches high, 18 inches long and 6.7 inches wide, in polypropylene. The narrow body parks beside the trap and pulls out on its wheels.
Inside, a large open compartment holds bottles and spray cleaners. A smaller front compartment holds sponges and cloths. A large front lip works as the handle, so the loaded caddy comes forward in one pull.
The body itself clears low plumbing at 4.4 inches high. Watch for the real fit figure: bottles ride above the rim, so add your tallest bottle’s height to the caddy before you judge the fit.
11. DecoBrothers Stackable Under Sink Organizer with Sliding Basket, Chrome — A chrome basket unit that stacks or stands alone
The live listing for this chrome model, BK-020-1, gives its size as 16.7 inches deep, 10.8 inches wide and 10.2 inches high. It is alloy steel with a polished chrome finish, and it stands freestanding.
The basket slides out for access, and units stack vertically to use cabinet height. Where height is short, the brand notes they can also sit side by side. The brand positions the line for bathroom essentials, on the counter or under the sink.
Watch for the footprint. At 10.8 inches wide and 16.7 inches deep, one unit takes a full side of a vanity. If you stack two, check the doubled height against the trap before you buy.
12. Copco Non-Skid Turntable, 12-Inch — A single-tier turntable for the corner beside the trap
A round footprint fits where a rectangle cannot. This single-tier turntable measures 12 inches across and about 1.5 inches high, so it sits on one side of the trap and turns the deep back corner into reachable storage.
The surface has a non-skid liner, and a raised rim of 3/8 inch keeps items from sliding off while it spins. The brand lists under-sink use for the line, and care is a wipe with a damp cloth.
It suits short bottles: skincare, nail polish, first-aid tubes and jars. Watch for the size line: Copco also sells 18-inch and two-tier versions, and those are kitchen-cabinet sizes. The 12-inch single tier is this pick.
13. Gorilla Grip Silicone Under Sink Mat, 15 x 22 — A leak-catching base layer for bins and drawers
A mat is a base layer, not a container, and this list uses it that way. This size measures 15 inches wide by 22 inches long, the brand’s bathroom-vanity size class, against its 34-inch kitchen sizes.
The mat is 100 percent waterproof silicone, BPA-free and stain-resistant, and it is dishwasher safe. A reinforced raised lip of 0.7 inch runs around the edge to hold liquid on the mat instead of the cabinet floor.
Raised dots on the top side keep bins and drawers from slipping, and the mat is non-adhesive, so it lifts out for cleaning. Watch for the brand’s care note: keep the area under the mat dry.
14. madesmart 2-Tier Organizer, Mini — The narrow Mini line for the strip beside a pedestal or trap
This is the Mini, a separate and much narrower madesmart line. The listing’s product data gives 13.66 inches deep, 5.08 inches wide and 6.81 inches high. That 5-inch width is the whole point of the pick.
It holds two removable slide-out baskets in plastic, and each basket has two adjustable dividers. The brand names under-bathroom-sink use for bath products, and the format also fits a medicine cabinet or a gap beside a pedestal base.
This is not the full-size madesmart organizer, which is about twice as wide. Watch for the width in use: the narrow baskets suit small bottles and tubes, and full-size bottles will not fit.
15. Xtreme Mats Bathroom Vanity Under Sink Mat, 25 x 19 — A rigid tray base sized for a 27-inch vanity
The second mat in this list is a rigid base, not a soft liner. It is flexible low-density polyethylene with raised, angled side walls and a textured surface, and the brand states it produces no toxic VOCs.
This size measures 25 1/4 inches wide by 19 1/4 inches deep, sized by the brand for a 27-inch bathroom vanity cabinet. The vanity line runs at a 19-inch depth class, against the brand’s 22-inch kitchen depth.
The brand states its mat line can hold up to 3.6 gallons in a leak, with channels that direct liquid toward a water sensor, sold separately. Watch for floor-fed plumbing: the brand says lines through the cabinet floor require the mat to be modified.
Measure first, then buy once. The floor-to-trap height rules out the tall racks, the width beside the trap rules out the wide ones, and what is left is a short list that truly fits your cabinet.
Picked that way, the best under-sink organizers for bathrooms turn a pipe-filled box into sorted storage for toiletries, hair tools and back-stock. The rest of the bathroom needs homes too.
