1. Kalrin Over-The-Toilet Storage Rack, 4-Tier Bathroom Organizer Shelf Over Toilet with Adjustable Shelf and Basket, Freestanding Space Saver Bathroom Shelves Above Toilet for Room (Vintage Brown) — Largest listed footprint

Listed details: dimensions 9.84″ D × 23.82″ W × 68.11″ H; item weight 7.9 kg; material Metal; color Brown.

The Kalrin Over-The-Toilet Storage Rack is a 4-tier metal and P2 particleboard organizer in a brown vintage style. Its listed dimensions are 9.84 inches deep by 23.82 inches wide by 68.11 inches high, making it the largest listed footprint at 1.63 square feet. The listing describes three open shelves, one storage basket, three removable hooks, and a toilet paper holder. Three wooden shelves are adjustable, while an X-shaped frame crossbar and wall-fixing nails are intended to improve stability. The listing states a weight of 7.9 kilograms, but it does not state shelf weight capacity.

Pros

• Includes open shelves, a storage basket, removable hooks, and a toilet paper holder.
• Three wooden shelves are listed as adjustable for different item heights.
• Metal X-shaped crossbar and wall-fixing nails are included for stability.

Cons

• At 1.63 square feet, it has the largest listed footprint of these three products.
• The listing describes three open shelves plus a basket while the specifications list four shelves; verify the configuration.
• The listing does not state the shelf weight capacity.

Who it is for / who should skip it: Pick this if you want the most listed bathroom organization features, including hooks, a basket, and toilet paper storage, and have room for its taller frame. Skip it if you need a smaller footprint or clearly documented shelf capacity.

2. 4-Tier Over The Toilet Storage Rack, Bathroom Organizer with One-Piece Metal Mesh Shelves, Over Toilet Shelf with Adjustable Feet & Anti-Tip Kit, Space-Saving Bathroom Storage, Black — Middle listed footprint

Listed details: dimensions 9.4″ D × 24.4″ W × 68.5″ H; material Metal; color Black.

This black 4-tier over-the-toilet storage rack has a modern style and a listed size of 9.4 inches deep by 24.4 inches wide by 68.5 inches high. Its 1.59-square-foot listed footprint is slightly smaller than the Kalrin rack, but its listed width and height are greater. The rack uses metal mesh shelves and includes adjustable leveling feet plus an anti-tip kit. The listing also says it has a simplified structure, included hardware, and clear instructions for assembly. It is described for bathroom storage and other spaces, but the listing does not provide an item weight or shelf weight capacity.

Pros

• Provides four listed storage tiers with one-piece metal mesh shelves.
• Adjustable leveling feet and an anti-tip kit are included.
• The listing says hardware and clear assembly instructions are included.

Cons

• Its 68.5-inch height may not suit every bathroom or toilet location.
• The listing does not state the product’s item weight.
• The listing does not state the weight capacity for its shelves.

Who it is for / who should skip it: Pick this if you want a modern black metal rack with four tiers, leveling feet, and an anti-tip kit. Skip it if you need documented load limits or are unsure that a 68.5-inch rack will fit your bathroom.

3. Bamboo Bathroom Shelf, Multifunctional Storage Shelf, 3-Tier — Smallest listed footprint

Listed details: dimensions 10″ D × 21.6″ W × 26″ H; item weight 7.4 pounds; material Bamboo; color Bamboo.

The Bamboo Bathroom Shelf is a 3-tier shelf made from bamboo with a safe lacquer finish, according to the listing. One dimension set gives 10 inches deep by 21.6 inches wide by 26 inches high, while the product bullet gives 23.6 inches long by 10.2 inches wide by 25.9 inches high. Because those measurements conflict, verify the actual size before choosing it for a specific spot. The listing also states a 7.4-pound item weight and a capacity of 22 pounds per shelf. Tools and accessories are included for assembly, and the shelf is described for bathrooms and other rooms.

Pros

• The listing states a 22-pound weight capacity per shelf.
• Bamboo construction and a lacquer finish are listed.
• Tools and accessories are included for assembly.

Cons

• The listing contradicts itself on dimensions, so verify the actual footprint before buying.
• It has three shelves rather than the four tiers listed for the other two products.
• The listing does not describe over-the-toilet storage, hooks, or a toilet paper holder.

Who it is for / who should skip it: Pick this if you want a shorter, freestanding bamboo shelf with a stated per-shelf capacity. Skip it if you need an over-the-toilet rack or cannot verify which of the conflicting dimension sets is correct.

What to check before buying bathroom shelf

Start with the available floor and wall space. For the two over-the-toilet racks, compare the listed footprints: Kalrin is 1.63 square feet, calculated from its listed 9.84-inch depth and 23.82-inch width, while the black rack is 1.59 square feet, calculated from 9.4 inches by 24.4 inches. These are listing-based footprint figures; also check the vertical clearance because Kalrin is listed at 68.11 inches high and the black rack at 68.5 inches. The bamboo shelf has conflicting dimensions, so do not rank it by footprint until the actual measurements are verified.

Next, match the storage format to your routine. Kalrin lists three open shelves, one storage basket, three removable hooks, and a toilet paper holder, although its specifications say four shelves. Verify that configuration before purchase. The black rack lists four metal mesh tiers, adjustable leveling feet, and an anti-tip kit. Choose it when balance on an uneven floor and a modern metal appearance matter more than added basket and hook storage. The bamboo model lists three tiers and does not list over-the-toilet hardware, so it is better suited to a shorter shelf location rather than a rack spanning the toilet.

Capacity documentation is another useful separator. The bamboo listing states 22 pounds per shelf, or 66 pounds across three shelves if each shelf reaches that stated limit (22 × 3 = 66), though actual loading should follow the listing’s instructions. Neither over-the-toilet rack has a stated shelf weight capacity. Kalrin lists an item weight of 7.9 kilograms, and the bamboo shelf lists 7.4 pounds; the black rack’s item weight is not stated. Finally, compare assembly and safety details: all three listings mention assembly-related information, while only the over-toilet racks list anti-tip or wall-fixing hardware.

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 48 inches of clear wall.

• Kalrin Over-The-Toilet Storage Rack: 48 − 23.82 = 24.18 inches spare; centred, 12.09 inches on each side before trim, plugs or curtains.
• 4-Tier Over The Toilet Storage Rack: 48 − 24.4 = 23.6 inches spare; centred, 11.8 inches on each side before trim, plugs or curtains.
• Bamboo Bathroom Shelf: 48 − 21.6 = 26.4 inches spare; centred, 13.2 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:

• Kalrin Over-The-Toilet Storage Rack: 36 + 9.84 = 45.84 inches of total path width.
• 4-Tier Over The Toilet Storage Rack: 36 + 9.4 = 45.4 inches of total path width.
• Bamboo Bathroom Shelf: 36 + 10 = 46 inches of total path width.

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

• Kalrin Over-The-Toilet Storage Rack: 9.84 × 23.82 = 234.39 sq in, or 1.63 sq ft.
• 4-Tier Over The Toilet Storage Rack: 9.4 × 24.4 = 229.36 sq in, or 1.59 sq ft.
• Bamboo Bathroom Shelf: 10 × 21.6 = 216 sq in, or 1.5 sq ft.

Mistakes to avoid

• Ignoring height above the toilet. The Kalrin rack is listed at 68.11 inches high and the black rack at 68.5 inches. Measure the available vertical space before choosing either over-the-toilet model.
• Treating conflicting bamboo dimensions as settled. The bamboo listing gives two different dimension sets. Verify the shelf’s actual length, width, and height before relying on its listed footprint.
• Assuming four tiers means four identical shelves. Kalrin’s listing describes three open shelves plus a storage basket while its specifications say four shelves. Confirm what is included and how it is arranged.
• Loading shelves without a stated limit. The bamboo shelf lists 22 pounds per shelf, but neither over-the-toilet rack states shelf capacity. Do not assume their shelves support the same load.

Frequently asked questions

Which bathroom shelf has the smallest listed footprint?

The black 4-tier over-the-toilet rack has the smallest listed footprint at 1.59 square feet. Kalrin is listed at 1.63 square feet. The bamboo shelf cannot be reliably compared because its listing gives conflicting dimensions: 10 by 21.6 by 26 inches in one place and 23.6 by 10.2 by 25.9 inches in another.

Which product states a shelf weight capacity?

The bamboo bathroom shelf is the only product whose listing states a shelf capacity: 22 pounds per shelf. Neither Kalrin nor the black 4-tier over-the-toilet rack has a stated shelf weight capacity in the provided information. Avoid assuming their shelves can hold the same amount as the bamboo model.

Are these all over-the-toilet bathroom shelves?

The Kalrin rack and the black 4-tier rack are explicitly described as over-the-toilet storage products. The bamboo model is described as a multifunctional 3-tier shelf for rooms including bathrooms, but the listing does not say it is designed to fit over a toilet. Check its height and placement needs before buying.

Which shelf includes the most listed accessories?

Kalrin lists the broadest group of accessories and storage elements: one storage basket, three removable hooks, and a toilet paper holder, along with open shelves. The black rack lists leveling feet and an anti-tip kit. The bamboo shelf listing mentions tools and accessories for assembly but does not list bathroom-specific accessories.
