1. Bathroom Wall Cabinet, Bathroom Cabinet Wall Mount with 2 Doors and Open Shelf, Over The Toilet Wall Storage, Wooden Medicine Cabinets — Smallest listed footprint
Listed details: dimensions 7.8″ D × 21.5″ W × 23.6″ H; item weight 7.94 kg; material Engineered Wood; color Bathroom Cabinet-black.
The listing gives this black wall cabinet as 7.8 inches deep, 21.5 inches wide and 23.6 inches tall, which works out to 1.16 sq ft of wall footprint, the smallest of the three. It has two doors plus an open shelf, and the specs list five shelves in engineered wood with a modern style. One bullet describes the inner adjustable shelf as having five different heights. The listing calls the material waterproof MDF and lists an item weight of 7.94 kg. It says the cabinet suits bathrooms, laundry rooms and kitchens. The listing does not state a weight capacity, the interior depth, or the mounting hardware included.
Pros
- Smallest listed footprint of the three, 1.16 sq ft, and the shortest at 23.6 inches tall
- Two doors plus an open shelf, so closed and open storage in one unit
- Lists an item weight (7.94 kg), which the second cabinet does not
Cons
- The specs list five shelves, but a bullet describes one inner adjustable shelf with five heights, so the real shelf count needs confirming
- At 7.8 inches deep the listing gives no interior depth, so tall bottles or bulky items may not fit
- Only the seller calls the MDF waterproof; the listing gives no moisture rating, weight capacity or wall hardware
Who it is for / who should skip it: Pick it if wall space is tight and you want the smallest footprint with a mix of open and closed storage. Skip it if you need a confirmed shelf count or a stated load limit.
2. ChooChoo Bathroom Wall Cabinet with 2 Doors, Over The Toilet — Middle listed footprint
Listed details: dimensions 8.8″ D × 21.1″ W × 24″ H; material Engineered Wood, Wood; color White.
This white cabinet is listed at 8.8 inches deep, 21.1 inches wide and 24 inches tall, a footprint of 1.29 sq ft, the middle of the three. It has two doors and two adjustable inside shelves with three height settings per the listing. The material is given as engineered wood and wood, with low-emission P2 grade MDF and water-based paint named in a bullet. The listing says the parts and accessories are numbered and that the instructions guide assembly step by step. It does not state an item weight, a weight capacity or how the cabinet attaches to the wall.
Pros
- Narrowest of the three at 21.1 inches wide
- Clearly stated shelf setup: two adjustable shelves with three height settings
- Listing says parts and accessories are numbered and instructions are step by step
Cons
- Deepest of the three at 8.8 inches, 1 inch more than the first cabinet (8.8 minus 7.8)
- Only two shelves are listed, fewer than the five the first cabinet’s specs claim
- No item weight, weight capacity or wall mounting details are stated
Who it is for / who should skip it: Pick it if you want the narrowest cabinet and a plainly stated two-shelf layout. Skip it if the extra depth would crowd the space above your toilet.

The third cabinet comes in natural oak and is listed at 8 inches deep, 23.5 inches wide and 24.5 inches tall, a footprint of 1.31 sq ft, the largest of the three. The listing names PB and MDF as materials and says PB has good load-bearing and moisture-proof properties. The title mentions an adjustable wood shelf and doors, and the specs give an item weight of 22.3 pounds. The listing says it suits small apartments and comes with a step-by-step instruction manual. It does not state a shelf count, a weight capacity or the included wall hardware.
Pros
- Tallest of the three at 24.5 inches, with a natural oak finish
- Lists PB and MDF construction and an item weight of 22.3 pounds
- Listing includes a step-by-step instruction manual
Cons
- Largest listed footprint, 1.31 sq ft, and the widest at 23.5 inches, 2 inches wider than the first cabinet (23.5 minus 21.5)
- The listing does not state how many shelves it has
- The moisture-proof wording is the seller’s claim; no rating, weight capacity or hardware list is given
Who it is for / who should skip it: Pick it if you have at least 23.5 inches of clear wall width and want the most height. Skip it if your wall is narrow or you need a stated shelf count.
What to check before buying bathroom cabinet over toilet wall mount
Start with the wall. Measure the clear width and height above your tank. Listed widths are 21.5, 21.1 and 23.5 inches; heights are 23.6, 24 and 24.5 inches. If your clear width is under 23.5 inches, rule out the third cabinet.
Next, check depth. The listings give 7.8, 8.8 and 8 inches, so the deepest sticks out 1 inch more than the shallowest (8.8 minus 7.8). Compare that with the space between the wall and where you stand or sit. The listings do not state interior depth, so a shallow outer size may mean shallow shelves.
Third, count the shelves. The second cabinet lists two adjustable shelves with three height settings. The first lists five shelves in its specs, but a bullet describes one inner adjustable shelf with five heights, so confirm the count with the seller. The third lists an adjustable wood shelf and no count.
Fourth, read the materials and weights. All three are engineered wood: MDF in each listing, and the third also names PB. Only the first (7.94 kg) and third (22.3 pounds) list an item weight, in different units, so do not compare them directly.
Last, check mounting. The listing text we have does not state a weight capacity or the wall hardware included for any of the three. A cabinet fixed above a toilet needs anchors suited to your wall type, so confirm both points before you load it.
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 36 inches of clear wall.
- Bathroom Wall Cabinet: 36 − 21.5 = 14.5 inches spare; centred, 7.25 inches on each side before trim, plugs or curtains.
- ChooChoo Bathroom Wall Cabinet with 2: 36 − 21.1 = 14.9 inches spare; centred, 7.45 inches on each side before trim, plugs or curtains.
- Bathroom Wall Storage Cabinet: 36 − 23.5 = 12.5 inches spare; centred, 6.25 inches on each side before trim, plugs or curtains.
Footprint. Depth × width, converted at 144 square inches per square foot:
- Bathroom Wall Cabinet: 7.8 × 21.5 = 167.7 sq in, or 1.16 sq ft.
- ChooChoo Bathroom Wall Cabinet with 2: 8.8 × 21.1 = 185.68 sq in, or 1.29 sq ft.
- Bathroom Wall Storage Cabinet: 8 × 23.5 = 188 sq in, or 1.31 sq ft.
Mistakes to avoid
- Measuring only the tank. Measure the clear wall width and height above it too. The listed widths run from 21.1 to 23.5 inches and the heights from 23.6 to 24.5 inches.
- Ignoring depth. The listed depths run from 7.8 to 8.8 inches, a 1-inch spread. That difference matters when the cabinet sits right above where you sit or stand.
- Trusting the shelf count without checking. The first cabinet’s specs list five shelves, while a bullet describes one inner adjustable shelf with five heights. Ask the seller before you plan your storage around it.
- Assuming a weight rating exists. None of the three listings states a weight capacity or the wall hardware included. Do not load heavy items until you have confirmed both and picked anchors that suit your wall.

Frequently asked questions
Which of these cabinets is narrowest?
The ChooChoo cabinet is listed at 21.1 inches wide, the narrowest of the three. The first is listed at 21.5 inches and the third at 23.5 inches. Measure the clear wall space above your tank first, then pick a cabinet narrower than that space. The listings do not state how much side clearance each one needs.
Do these listings state a weight capacity?
No. The listing text we have for all three cabinets does not state how much weight the shelves or the cabinet can hold. Only two list an item weight: 7.94 kg for the first and 22.3 pounds for the third. Ask the seller about capacity and included wall hardware before you store heavy items.
How deep are these over-the-toilet cabinets?
The listings give 7.8 inches for the first cabinet, 8.8 inches for the ChooChoo and 8 inches for the third. The gap between the deepest and the shallowest is 1 inch (8.8 minus 7.8). The listings do not state interior depth, so check with the seller if you want to store tall bottles.
Are these cabinets waterproof?
The first listing calls its MDF waterproof, the second names low-emission P2 grade MDF with water-based paint, and the third says its PB is moisture-proof and suited to humid environments. These are the sellers’ own claims, and none of the listings gives a moisture rating or test result, so treat them as unverified.
