1. Mrosaa Storage Box Outdoor Caninet,Resin Indoor Storage Box Waterproof Outdoor Storage Cabinets for Patio/Garden/Backyard — Middle listed footprint

Listed details: dimensions 15.08″ D × 33.5″ W × 34.25″ H; item weight 32.7 pounds; material Resin; color Black-1 shelf.

The Mrosaa is a black resin storage cabinet with one shelf, titled as both an outdoor cabinet and an indoor storage box. The spec table lists 15.08 in D × 33.5 in W × 34.25 in H, or 3.51 sq ft, and 32.7 pounds. A bullet gives external dimensions of 34.3 × 15 × 36.2 inches and internal dimensions of 33.98 in H × 13.5 in D × 30.31 in W, so the height is listed two ways. The listing says it assembles with simple tools and rinses clean with water. It does not state a capacity in gallons or a weight limit.

Pros

• Internal dimensions are listed (33.98 in H × 13.5 in D × 30.31 in W), so you can check your items against them
• One shelf is included, and the smooth surface rinses clean with water per the listing
• Accessories are packaged with it and assembly needs only simple tools, per the listing

Cons

• External height is listed as 34.25 inches in the specs and 36.2 inches in a bullet, so confirm it before planning clearance
• The title mixes outdoor cabinet and indoor storage box, and the bullets suggest shoes and towels, so it is not clearly built for exposed outdoor use
• No gallon capacity and no weight limit are stated, and it needs assembly

Who it is for / who should skip it: Pick it if you want a cabinet with doors and one shelf and have items that fit the listed 13.5 inch interior depth. Skip it if you need a stated capacity or a confirmed height.

2. KINYING Outdoor Storage Cabinet Waterproof, 60 Gallon Resin Outdoor Storage Shed for Patio/Garden/Backyard, Outdoor Storage Box for Cushions,Garden Tools and Pool Supplies(White with 1 Shelving) — Largest listed footprint

Listed details: dimensions 34.3″ L × 15″ W × 33.5″ H; item weight 32.7 pounds; material High Density Polyethylene (HDPE); color White with 1 shelving.

The KINYING is a white HDPE cabinet listed at 60 gallons, with one shelf included and room for up to three. The listed size is 34.3 in L × 15 in W × 33.5 in H, or 3.57 sq ft, the largest listed footprint of the three, and the weight is 32.7 pounds. A bullet gives internal dimensions of 33.8 in W × 13.5 in D × 30.1 in H. The listing calls it weather-resistant, UV protected and waterproof, and says one person can assemble it in 30 minutes. A bullet also calls it a deck box.

Pros

• Largest stated capacity of the three at 60 gallons, with internal dimensions listed
• Comes with one shelf and fits up to three, with more shelves sold separately
• Listed as weather-resistant, UV protected and waterproof, with one-person assembly in 30 minutes

Cons

• Largest listed footprint at 3.57 sq ft (34.3 × 15 inches)
• Called a cabinet, a shed and a deck box in different places, and the material is HDPE in the specs but imported high density resin in a bullet
• No weight limit is stated, extra shelves cost extra, and its 32.7 pounds and near-identical exterior size make it close to the Mrosaa

Who it is for / who should skip it: Pick it if you want the largest stated capacity and shelving you can expand. Skip it if you have very little patio depth or need a stated load limit.

3. Keter Velo 30 Gallon Outdoor Storage Cabinet — Smallest listed footprint

Listed details: dimensions 24.5″ L × 18.5″ W × 24.8″ H; item weight 12.3 pounds; material Resin; color Graphite.

The Keter Velo is a 30 gallon graphite resin cabinet with steel reinforcement in the body and lid. The listing gives 24.5 in L × 18.5 in W × 24.8 in H, or 3.15 sq ft, the smallest listed footprint of the three, and 12.3 pounds, well under the 32.7 pounds of the other two. It describes protection against sun, rain and snow, built-in ventilation, integrated handles and a lockable latch, with the lock not included. The text we reviewed states no internal size, weight limit or assembly details, and describes all-weather protection rather than calling it waterproof.

Pros

• Lightest at 12.3 pounds, with integrated handles for repositioning
• Steel reinforcement in both the body and the lid, per the listing
• Smallest footprint at 3.15 sq ft and the shortest at 24.8 inches tall

Cons

• Half the stated capacity of the KINYING (30 gallons versus 60), and no shelf is mentioned
• The lockable latch needs a lock that is not included, and built-in ventilation means it is described as airflow-friendly rather than waterproof
• No internal dimensions, weight limit or assembly details appear in the text we reviewed

Who it is for / who should skip it: Pick it if you want a compact, light cabinet you can move and lock for cushions and tools. Skip it if you need a shelf, a stated internal size or a waterproof claim.

What to check before buying weatherproof outdoor storage cabinets

Start with the weather claims, because they differ. The Mrosaa title says waterproof and the KINYING listing says weather-resistant, UV protected and waterproof. The Keter Velo describes protection against sun, rain and snow, plus built-in ventilation. None of the three gives a waterproof rating or test.

Second, usable space. The KINYING states 60 gallons and the Keter Velo 30 gallons; the Mrosaa states no gallon figure. For fit, use the internal dimensions the Mrosaa and KINYING list: 13.5 inches deep for both, with 33.98 in H × 30.31 in W for the Mrosaa and 30.1 in H × 33.8 in W for the KINYING. The Keter Velo lists none.

Third, footprint: the Keter Velo is smallest at 3.15 sq ft, the Mrosaa is 3.51 sq ft and the KINYING is 3.57 sq ft. The gap from smallest to largest is 0.42 sq ft (3.57 − 3.15), so height matters more: the Keter Velo is 24.8 inches tall, while the other two are listed at 33.5 and 34.25 inches.

Fourth, weight and moving. The Keter Velo is listed at 12.3 pounds with integrated handles. The Mrosaa and KINYING both list 32.7 pounds. None of the listings states a load limit for shelves or lid.

Fifth, access and build. The Keter Velo adds steel reinforcement in the body and lid and a lockable latch, but the lock is not included. The KINYING comes with one shelf and fits up to three, and extra shelves are sold separately; the Mrosaa lists one shelf. The KINYING lists assembly in 30 minutes by one person.

Choose the Keter Velo for the smallest footprint, the lightest weight and a lockable latch, accepting 30 gallons and no stated internal size. Choose the Mrosaa only if its internal dimensions fit your items, and check its height, which the listing gives as both 34.25 and 36.2 inches.

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.

• Mrosaa Storage Box Outdoor Caninet: 48 − 33.5 = 14.5 inches spare; centred, 7.25 inches on each side before trim, plugs or curtains.
• KINYING Outdoor Storage Cabinet Waterproof: 48 − 15 = 33 inches spare; centred, 16.5 inches on each side before trim, plugs or curtains.
• Keter Velo 30 Gallon Outdoor Storage: 48 − 18.5 = 29.5 inches spare; centred, 14.75 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:

• Mrosaa Storage Box Outdoor Caninet: 36 + 15.08 = 51.08 inches of total path width.
• KINYING Outdoor Storage Cabinet Waterproof: 36 + 34.3 = 70.3 inches of total path width.
• Keter Velo 30 Gallon Outdoor Storage: 36 + 24.5 = 60.5 inches of total path width.

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

• Mrosaa Storage Box Outdoor Caninet: 15.08 × 33.5 = 505.18 sq in, or 3.51 sq ft.
• KINYING Outdoor Storage Cabinet Waterproof: 34.3 × 15 = 514.5 sq in, or 3.57 sq ft.
• Keter Velo 30 Gallon Outdoor Storage: 24.5 × 18.5 = 453.25 sq in, or 3.15 sq ft.

Mistakes to avoid

• Reading waterproof as a rating. The Mrosaa and KINYING say waterproof, the Keter Velo says all-weather protection with ventilation, and none gives a rating or test.
• Skipping the internal size. The Mrosaa and KINYING both list 13.5 inches of interior depth, and the Keter Velo lists none. Measure your items against the interior, not the outside.
• Trusting one height. The Mrosaa lists 34.25 inches in the specs but 36.2 inches in a bullet. Confirm it before placing the cabinet under a shelf or ledge.
• Assuming the lock is included.

Frequently asked questions

Are weatherproof outdoor storage cabinets really waterproof?

The listings make claims but give no tested rating. The Mrosaa title and the KINYING listing say waterproof, and the KINYING adds weather-resistant and UV protected. The Keter Velo text describes protection against sun, rain and snow with built-in ventilation. Treat all three as seller claims and check the listing before storing items that must stay completely dry.

How much can these cabinets hold?

The KINYING states 60 gallons and the Keter Velo states 30 gallons. The Mrosaa lists no gallon figure, but gives internal dimensions of 33.98 in H × 13.5 in D × 30.31 in W. None of the listing text we reviewed states a weight limit for the shelves or the lid.

Which cabinet is easiest to move?

The Keter Velo is listed at 12.3 pounds and has integrated handles. The Mrosaa and KINYING each list 32.7 pounds. The Keter Velo is also the smallest at 3.15 sq ft and 24.8 inches tall. Check the listing for how you would carry the other two, since neither mentions handles in the text we reviewed.

Can I lock these cabinets?

The Keter Velo has a lockable latch, but the listing says the lock is not included. The Mrosaa and KINYING listings we reviewed do not mention a lock or latch. If security matters, confirm the locking option with the seller before ordering.
