1. Delamu 2-Tier Multi-Purpose Bathroom Under Sink Organizers and Storage, Stackable Kitchen Pantry Organization, Pull Out Medicine Cabinet Organizer with Movable Dividers, White, 2 Pack — Middle listed footprint

Listed details: dimensions 13.19″ D × 8.27″ W × 10.63″ H; item weight 2.4 pounds; listed maximum weight 30.06 kg; material ‌PET; color White.

Delamu’s two-tier under-sink organizer is listed at 13.19 inches deep, 8.27 inches wide, and 10.63 inches high, with a smaller 9.06-inch-high size also described. The listing states that the set has four slide-out drawers and eight movable dividers, allowing bathroom supplies to be separated by type. Its white PET construction is paired with clear acrylic organizers and aluminum alloy support rods. The listing gives a 30.06-kilogram maximum weight recommendation, but its separate 500-milliliter capacity specification is unclear. Verify which size and configuration you will receive before ordering.

Pros

• Four slide-out drawers and eight movable dividers are listed.
• Two height options are described: 9.06 inches and 10.63 inches.
• The listing states a 30.06-kilogram maximum weight recommendation.

Cons

• The listing gives different heights for the smaller and larger sizes.
• The 500-milliliter capacity specification is difficult to interpret for bathroom storage.
• The listing does not state the interior drawer dimensions.

Who it is for / who should skip it: Pick it if you want multiple drawers and adjustable dividers in a white organizer. Skip it if you need one confirmed height or clearly stated interior dimensions; verify the selected size first.

2. PXRACK Under Sink Organizer, Adjustable Height, 2 Tier Pull Out Under Cabinet Organizer, Slide Out Thickened Metal Under Sink Storage for Kitchen Bathroom Laundry Pantry Cabinet, White, Large-2-Pack — Largest listed footprint

Listed details: dimensions 15.9″ D × 11.8″ W × 16.9″ H; item weight 4.05 kg; material Thickened Metal Frame, Wooden Drawer Handle; color White.

The PXRACK organizer is the largest listed option, measuring 15.9 inches deep, 11.8 inches wide, and 16.9 inches high. Its C-shaped design is intended to leave room for sink plumbing, while two sliding drawers provide access to items on both levels. The height adjusts through five levels from 13.6 to 16.9 inches, and the listing says the space below the upper basket can hold items up to 13 inches high. This white model uses a thickened metal frame and wooden drawer handle. The listing does not state a maximum weight recommendation.

Pros

• Height adjusts through five levels from 13.6 to 16.9 inches.
• Two sliding drawers and two shelves are listed.
• The C-shaped design is intended to work around plumbing.

Cons

• Its 1.3-square-foot listed footprint is the largest of these options.
• Its 15.9-inch depth and 16.9-inch maximum height may not suit smaller cabinets.

Who it is for / who should skip it: Pick it if your cabinet has room for the largest organizer and you need adjustable height around plumbing. Skip it when cabinet depth or height is limited, or when a stated weight limit is important.

3. Vtopmart 4 Pack Pull Out Bathroom Under Sink Organizer (S-Standard) — Smallest listed footprint

Listed details: dimensions 11.8″ D × 7.5″ W × 10″ H; item weight 2 pounds; listed maximum weight 15 pounds; material Plastic; color Transparent.

Vtopmart’s four-pack is the smallest listed option, with each organizer measuring 11.8 inches deep, 7.5 inches wide, and 10 inches high. Each two-tier unit has two pull-out drawers with tracks and built-in handles. The listing says no tools are required for assembly and describes transparent PET construction with four stainless steel support tubes. It also says the organizers can share limited space with sink pipes, although cabinet compatibility still depends on the available opening. The listed maximum weight recommendation and capacity are both 15 pounds. This product is sold as a four-pack.

Pros

• The four-pack supplies four organizers.
• Each unit has two pull-out drawers and built-in handles.
• No tools are required for assembly, according to the listing.

Cons

• The 7.5-inch width limits the space available in each organizer.
• The 15-pound maximum weight recommendation applies to the listed product but is not further explained.
• Four units may be unnecessary if you only need one under-sink organizer.

Who it is for / who should skip it: Pick it if you need several compact organizers or have a narrow cabinet opening. Skip it if you need wide shelves, a taller unit, or only one organizer rather than a four-pack.

What to check before buying shelves for under bathroom sink

Start with cabinet clearance. Measure the usable width, front-to-back depth, and height around the drain and supply lines, then compare those measurements with each organizer’s listed outside dimensions. A unit must fit the cabinet opening and leave enough room for drawers to slide. Among these products, Vtopmart is the smallest listed footprint at 0.61 square feet, calculated from its 11.8-inch depth and 7.5-inch width. Delamu is listed at 0.76 square feet, while PXRACK is largest at 1.3 square feet. These are listed footprints, not guarantees of plumbing clearance.

Next, check height and pipe placement. PXRACK adjusts from 13.6 to 16.9 inches through five levels and uses a C-shaped design intended to avoid plumbing. Delamu lists two height choices, 9.06 inches and 10.63 inches, so confirm the selected size. Vtopmart is 10 inches high and is described as suitable for limited space with pipes. If your cabinet is low, compare the actual opening rather than relying on the title.

Then choose access and organization. Delamu lists four slide-out drawers and eight movable dividers, making it the better fit for separating small bathroom items. PXRACK lists two tiers and two sliding drawers, with height adjustment for larger items. Vtopmart lists two pull-out drawers per organizer and comes as a four-pack, useful when several narrow storage spots are available.

Finally, consider load information and setup. Vtopmart lists a 15-pound maximum weight recommendation and no-tool assembly. Delamu lists a 30.06-kilogram maximum weight recommendation, but its 500-milliliter capacity field is unclear. PXRACK’s listing does not state a maximum weight recommendation. Choose the product whose stated dimensions, access, pack size, and available load information match your cabinet and supplies.

Worked example: fit math for these three options

This worked example is our own planning arithmetic from the listed dimensions, not test results. The wall length and walkway width are assumed example values; replace them with your measurements.

Wall example. Assume 24 inches of clear wall.

• Delamu 2-Tier Multi-Purpose Bathroom Under Sink: 24 − 8.27 = 15.73 inches spare; centred, 7.87 inches on each side before trim, plugs or curtains.
• PXRACK Under Sink Organizer: 24 − 11.8 = 12.2 inches spare; centred, 6.1 inches on each side before trim, plugs or curtains.
• Vtopmart 4 Pack Pull Out Bathroom: 24 − 7.5 = 16.5 inches spare; centred, 8.25 inches on each side before trim, plugs or curtains.

Walkway example. The US Access Board gives 36 inches as the minimum clear width for an accessible route. That figure is a yardstick, not a rule for private homes. To keep 36 inches clear beside each product, the walkway between it and the opposite obstacle must be at least 36 inches plus its depth:

• Delamu 2-Tier Multi-Purpose Bathroom Under Sink: 36 + 13.19 = 49.19 inches of total path width.
• PXRACK Under Sink Organizer: 36 + 15.9 = 51.9 inches of total path width.
• Vtopmart 4 Pack Pull Out Bathroom: 36 + 11.8 = 47.8 inches of total path width.

Footprint. Depth × width, converted at 144 square inches per square foot:

• Delamu 2-Tier Multi-Purpose Bathroom Under Sink: 13.19 × 8.27 = 109.08 sq in, or 0.76 sq ft.
• PXRACK Under Sink Organizer: 15.9 × 11.8 = 187.62 sq in, or 1.3 sq ft.
• Vtopmart 4 Pack Pull Out Bathroom: 11.8 × 7.5 = 88.5 sq in, or 0.61 sq ft.

Mistakes to avoid

• Ignoring the plumbing path. A shelf can fit the cabinet opening but still block the drain or supply lines. Compare the pipe location with the C-shaped PXRACK design or the pipe-clearance claims for the other organizers.
• Confusing height options. Delamu lists both a 9.06-inch smaller size and a 10.63-inch larger size. Confirm the selected size instead of assuming the displayed height applies to every variant.
• Treating a four-pack as one unit. Vtopmart is listed as a four-pack, with each organizer measuring 11.8 by 7.5 by 10 inches. Check whether you have room for multiple units before choosing it.
• Skipping the weight information. Vtopmart lists a 15-pound maximum and Delamu lists a 30.06-kilogram recommendation, while PXRACK does not state one. Match heavier bottles to a product with a clearly stated limit.

Frequently asked questions

Which organizer has the smallest listed footprint?

Vtopmart has the smallest listed footprint at 0.61 square feet, based on its 11.8-inch depth and 7.5-inch width. Its individual organizer is 10 inches high. The listing describes it as suitable for limited space with pipes, but you should still measure the cabinet opening and plumbing before ordering.

Which option is best for adjustable height?

PXRACK offers the clearest height adjustment. Its listing describes five levels from 13.6 to 16.9 inches and says the C-shaped design helps avoid sink plumbing. Measure the cabinet’s usable height first, because the 16.9-inch maximum may not fit every under-sink space.

Does Delamu have different size options?

Yes. The listing describes a smaller size measuring 8.27 by 13.19 by 9.06 inches and a larger size measuring 8.27 by 13.19 by 10.63 inches. Confirm which size is selected before purchase. The listing also describes four slide-out drawers and eight movable dividers.

Which product includes multiple organizers?

Vtopmart is listed as a four-pack. Each organizer measures 11.8 inches deep, 7.5 inches wide, and 10 inches high, with two pull-out drawers. This can suit several narrow storage areas, but four units may be more than you need if your cabinet has only one usable section.
