1. Simple Trending Over The Toilet Storage Cabinet, Metal Bathroom Shelf Organizer with Paper Holder and Hooks, 3 Tier, Black — Largest listed footprint

Listed details: dimensions 24″ D × 13″ W × 64″ H; item weight 16 ounces; material Metal; color Black With Towel Rack.

The Simple Trending unit is a metal, three-shelf organizer with a towel rack and three hooks. Its listed dimensions are 24 inches deep by 13 inches wide by 64 inches high, and the listing says it uses the unused area above a toilet. The listing also describes thickened steel tubing, a waterproof coating and securing straps. It lists a weight of 16 ounces, but gives no shelf weight capacity or interior storage dimensions. The listed depth is notably greater than the other two options, so measure the available floor and toilet area rather than assuming it will tuck close to the wall.

Pros

• Three shelves, a towel rack and three hooks are listed.
• The listing states it has a waterproof coating and securing straps.
• The listing gives overall dimensions: 24 inches deep, 13 inches wide and 64 inches high.

Cons

• At 24 inches deep, its listed footprint is larger than the other two models.
• The listing does not state weight capacity or shelf dimensions.
• The 16-ounce listed item weight may need verification given the metal construction.

Who it is for / who should skip it: Choose it if you want a towel rack and hooks and have room for its listed depth. Skip it if your toilet area is shallow or you need a stated load limit.

2. 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) — Smallest 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 rack has four tiers: three open shelves and one storage basket, according to its listing. It is listed at 9.84 inches deep, 23.82 inches wide and 68.11 inches high, the tallest of these three products. Its metal frame and P2 particleboard panels are paired with an X-shaped crossbar and wall-fixing nails. The listing says three wooden shelves are adjustable and also mentions three removable hooks and a toilet-paper holder. It does not state shelf capacity or interior dimensions, and the listing’s phrase “max” does not provide a usable load figure here.

Pros

• Four tiers include three open shelves and one storage basket.
• The listing describes three adjustable shelves, three removable hooks and a toilet-paper holder.
• The listing specifies an X-shaped crossbar and wall-fixing nails for stability.

Cons

• At 68.11 inches tall, it is taller than the other two listed racks.
• The listing does not state the weight capacity or the basket’s interior dimensions.
• Its P2 particleboard shelves may not suit buyers seeking an all-metal shelf surface.

Who it is for / who should skip it: Pick it if you want a basket, adjustable shelves and the narrowest listed depth. Skip it if the room has limited vertical clearance or you need a published load limit.

3. samstar 4 Tier Over The Toilet Storage Rack, Bathroom Organizer Shelves Cabinet Above Toilet, with Adjustable Height Freestanding Shelf Space Saver, Black — Middle listed footprint

Listed details: dimensions 9.8″ D × 24.6″ W × 64.8″ H; material Metal; color 4 Tier Blackblack.

The samstar rack is a four-tier organizer with four removable hooks, a metal frame and two adjustable shelves, according to the listing. Its dimensions are 9.8 inches deep by 24.6 inches wide by 64.8 inches high. The listing says the bottom two tiers and the bottom support rod each have 2 inches of adjustment, and that four retaining straps are included. Unlike the Kalrin, its listing does not identify a basket or toilet-paper holder. It also provides no item weight, shelf load capacity or shelf dimensions, so verify those details if they affect your setup.

Pros

• Four tiers and four removable hooks are listed.
• The listing states that two shelves and the bottom support rod adjust by 2 inches.
• The listing says four retaining straps are included.

Cons

• The listing does not specify a shelf weight limit or item weight.
• No basket or toilet-paper holder is identified in the supplied listing details.
• Its 24.6-inch width is the widest of the three listed products.

Who it is for / who should skip it: Choose it if you want a four-tier metal rack with adjustable lower sections and retaining straps. Skip it if a basket or toilet-paper holder is essential, or if width is tight.

What to check before buying bathroom behind the toilet shelf

Start with the measured space. Compare the rack’s full width and depth with the clear floor area around the toilet, and check height against shelves, windows or other fixtures. The supplied dimensions make the Kalrin the shallowest at 9.84 inches, followed closely by the samstar at 9.8 inches; the Simple Trending listing gives a much greater 24-inch depth. The listed footprint values are 1.63, 1.67 and 2.17 square feet, respectively, but the Simple Trending dimensions and its footprint label merit checking before purchase. Do not treat footprint alone as a guarantee that a rack will fit around a toilet.

Next, decide what kind of storage you need. Kalrin lists three open shelves plus a basket, a toilet-paper holder and three removable hooks. Samstar lists four tiers and four removable hooks, but the supplied details do not identify a basket or paper holder. Simple Trending lists three shelves, a towel rack and three hooks. Choose based on the specific items you plan to store, not just the tier count.

Then check adjustability and stability. Kalrin says its three wooden shelves adjust; samstar specifies 2 inches of adjustment for two shelves and the bottom support rod. The listings describe wall-fixing nails and an X-shaped crossbar for Kalrin, and four retaining straps for samstar. Simple Trending mentions securing straps. Follow the product’s installation instructions and confirm that wall attachment works for your bathroom.

Finally, look for missing measurements before relying on the rack for heavy or bulky items. None of these supplied listings states a shelf weight capacity or shelf interior dimensions. Kalrin and samstar are both about 10 inches deep, while Simple Trending’s listed depth is 24 inches; if you need a shallow profile, compare that discrepancy with the manufacturer’s current dimensions. Ask the seller for load limits and clearances if they matter to your decision.

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.

• Simple Trending Over The Toilet Storage: 48 − 13 = 35 inches spare; centred, 17.5 inches on each side before trim, plugs or curtains.
• 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.
• samstar 4 Tier Over The Toilet: 48 − 24.6 = 23.4 inches spare; centred, 11.7 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:

• Simple Trending Over The Toilet Storage: 36 + 24 = 60 inches of total path width.
• Kalrin Over-The-Toilet Storage Rack: 36 + 9.84 = 45.84 inches of total path width.
• samstar 4 Tier Over The Toilet: 36 + 9.8 = 45.8 inches of total path width.

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

• Simple Trending Over The Toilet Storage: 24 × 13 = 312 sq in, or 2.17 sq ft.
• Kalrin Over-The-Toilet Storage Rack: 9.84 × 23.82 = 234.39 sq in, or 1.63 sq ft.
• samstar 4 Tier Over The Toilet: 9.8 × 24.6 = 241.08 sq in, or 1.67 sq ft.

Mistakes to avoid

• Choosing by shelf count alone. Kalrin and samstar each list four tiers, but Kalrin includes a basket and paper holder while samstar specifies four hooks. Match the accessories to what you store.
• Ignoring depth. Simple Trending is listed at 24 inches deep, compared with 9.84 inches for Kalrin and 9.8 inches for samstar. Measure the usable floor area and verify the dimension before ordering.
• Assuming adjustable means fully flexible. Kalrin says its three shelves adjust, while samstar specifies 2 inches of adjustment for two shelves and the bottom support rod. Check the stated adjustment against the heights of your supplies.
• Treating stability features as a load rating. Crossbars, wall-fixing nails and retaining straps are listed, but no product here gives a shelf weight capacity. Get a load limit from the seller before storing heavy items.

Frequently asked questions

Which shelf has the smallest listed footprint?

The supplied data labels Kalrin as the smallest at 1.63 square feet, followed by samstar at 1.67 square feet and Simple Trending at 2.17 square feet. Their listed depths are also very different: 9.84 inches, 9.8 inches and 24 inches, respectively. Measure your actual space and verify the Simple Trending dimensions before choosing by footprint.

Which option has adjustable shelves?

Kalrin’s listing says three wooden shelves are adjustable. Samstar’s listing says two shelves and the bottom support rod adjust by 2 inches. The supplied details do not identify adjustable shelves on the Simple Trending model. Check the product instructions for how adjustments work and whether the positions suit the items you plan to store.

Do these racks have a stated weight capacity?

No weight capacity is included in the supplied data for any of the three products. Stability details such as straps, a crossbar or wall-fixing nails are not a substitute for a stated load limit. If you plan to store heavy bottles or other weighty items, ask the seller for shelf and total capacity before buying.

Which model includes a toilet-paper holder?

The supplied listing details identify a toilet-paper holder on both Simple Trending and Kalrin. Kalrin also lists a storage basket and three removable hooks; Simple Trending lists a towel rack and three hooks. The samstar details mention four removable hooks but do not identify a paper holder, so confirm with the seller if that accessory is important.
