Best Indoor Storage Units
As an Amazon Associate we earn from qualifying purchases.
The best indoor storage units match your room, the weight of what you plan to store and how much you want to hide. An open wire or metal rack suits a utility room or a garage corner, a plastic shelving unit suits a laundry room or pantry, and a cabinet with doors and a lock suits tools or chemicals you want out of reach. Before you buy, measure the wall and the floor, then check the listed weight rating and shelf count. The six units below are compared using only the figures each listing states, so where a number is missing, we say so.
Quick answer
- Hidden storage with a lock: a resin cabinet with two shelves and lockable doors, rated to 336 pounds.
- Four solid plastic shelves in a utility room: a four-shelf plastic unit rated to 50 pounds per shelf.
- A cube display for bedrooms or offices: a 16-cube unit with a listed 11-pound limit per cube.
- A heavy open rack for bins or tools: a five-tier metal unit rated to 264 pounds or a five-wire rack rated to 500 pounds.
Start with the room and the load
Indoor storage works best when you match the unit to the room. A laundry room or pantry usually needs open shelves that are easy to wipe clean. A bedroom or living room needs a unit that looks finished, and an office needs a unit that holds binders without taking much floor space. A garage or basement can take heavier units with more load capacity. The listings below include units for each of these settings, and each one states the room types it suits.
Load is the second test. Weight ratings in this group range from 11 pounds per cube to 500 pounds for a full rack. A unit rated for 50 pounds per shelf is not the same as one rated for 500 pounds total, so compare the figure to the heaviest item you plan to store. If the listing gives a minimum or a maximum, use the lower number when you plan a load.
Compared at a glance
| Unit | Material | Shelves or cubes | Listed size (D x W x H) | Weight rating stated |
|---|---|---|---|---|
| Rubbermaid Freestanding Storage Cabinet | Resin, polyethylene | 2 shelves with doors | 18 in x 36 in x 37 in | 336 lb maximum |
| Sterilite 4-Shelf Utility Unit | Plastic with tubular frame | 4 shelves | 14.38 in x 34.5 in x 57 in | 200 lb maximum; 50 lb per shelf |
| C&AHOME 16-Cube Storage Organizer, White | Plastic with metal frame | 16 cubes | 12.4 in x 48.4 in x 48.4 in | 11 lb per cube listed |
| Whitmor 2-Wire Shelving Unit with Basket | Metal, silver | 1 shelf with basket | 14 in x 15 in x 15 in | 250 lb per shelf |
| REGILLER 5-Wire Shelving Rack, Silver | Steel and plastic | 5 adjustable shelves | 11.8 in x 16.6 in x 53.5 in | 500 lb maximum |
| HOMEDANT 5-Tier Metal Shelving Unit | Metal, white finish | 5 adjustable tiers | 16.5 in x 24.4 in x 59.5 in | 264 lb maximum |
The listings differ on what a weight figure refers to. The Sterilite unit lists both a 200-pound maximum and 50 pounds per shelf, and the C&AHOME figure applies to each cube. Read the bullets for the exact wording before you load a unit.
Cabinets with doors and locks
A cabinet hides what you store and keeps children and pets away from some items. The Rubbermaid Freestanding Storage Cabinet is the most enclosed unit here. It measures 18 inches deep, 36 inches wide and 37 inches high, and it weighs 28.3 pounds. The bullets describe a resin body that will not rot, rust, dent or peel, and a snap-together design with no tools. The unit holds a maximum of 336 pounds and has 13.5 cubic feet of storage. It has one ventilated shelf and one solid shelf, and the shelves cannot be adjusted or removed. The doors lock, but the listing says the lock is not included, so buy one separately if you need it. The listing lists tools as the recommended use, and says it fits a garage, basement or shed. It works best for lawn care items, garden tools and cleaning supplies that you want out of sight.
Plastic shelving for utility rooms
Plastic shelving suits a space that gets damp or messy. The Sterilite four-shelf unit is a heavy-duty plastic rack with a tubular frame and solid plastic shelves. Its listed size is 14.38 inches deep, 34.5 inches wide and 57 inches high, and the item weighs 17.1 pounds. The listing gives 16.08 inches of clearance between shelves and a 50-pound limit for each of the four shelves, with a maximum of 200 pounds for the whole unit. The bullets say it snaps together in minutes without tools. The listing describes the brand as made in the USA and states that its plastic is BPA-free and phthalate-free. It works for bins, totes, tools and seasonal supplies in a workshop, a pantry or a laundry area.
Cube units for bedrooms and offices
Cube units are useful when you want shelves that can hold baskets, books and bins in a neat grid. The C&AHOME 16-cube unit in white measures 12.4 inches deep, 48.4 inches wide and 48.4 inches high. Each cube is listed at 11.8 inches on each side. The bullets describe a plastic body with a metal frame and ABS connectors, and say it can be assembled with a wooden mallet and the included manual. The listing says you can use one set as a storage cabinet or join several sets. The specs list a weight capacity of 11 pounds, so use the cubes for light items such as folded clothes, books and boxes. Its room types are a bedroom, a living room and an office.
Open metal racks
Open metal racks give the most flexible shelf space and carry the heaviest loads in this group. The Whitmor unit is a small stacking shelf with a basket, measuring 14 inches deep, 15 inches wide and 15 inches high. Its listing gives 250 pounds per shelf and says it assembles without specialized tools. It suits a garage, a kitchen, a laundry room or an office corner.
The REGILLER five-wire rack is taller, at 53.5 inches high, with five adjustable shelves in a 16.6-inch width and an 11.8-inch depth. The listing gives a total static maximum load of 500 pounds, and the bullets say the adjustable feet level the rack on uneven floors. It does not include hooks or shelf liners. The listing says the rack can go in a bathroom, closet, garage, kitchen, laundry room or office, and that the powder-coated finish protects it from water and rust.
The HOMEDANT five-tier unit is the widest of the metal racks, measuring 16.5 inches deep and 24.4 inches wide and 59.5 inches high. It weighs 40.8 pounds and has a listed maximum of 264 pounds. The bullets describe a snap-together, boltless build and say each tier can be repositioned. The listing says it is made in Korea and suits a garage, basement, pantry, closet or home office.
Review: Sterilite 4-Shelf Utility Unit
The Sterilite unit is the most practical indoor pick for a room that needs plastic shelves, so we describe it in depth. The listing presents a flat-grey plastic unit with four solid shelves. Its overall size is 57 inches high, 34.5 inches wide and 14.38 inches deep, and the specs give a weight of 17.1 pounds. The clearance between shelves is 16.08 inches, which is enough for a standard storage tote or a row of paint cans on the shelf below. The bullets say each shelf supports up to 50 pounds, and the specs give a maximum of 200 pounds for the whole unit, so spread heavy items across the shelves rather than loading one.
Assembly is listed as tool-free. The bullets describe a tubular frame that snaps together in minutes, and solid shelves that the listing says resist denting. Plastic shelves suit a laundry room or a pantry, where spills and dust are common. The listing says the plastic is BPA-free and phthalate-free, and that the products have been made in the USA since 1939. The room types in the specs include a garage, a playroom, a laundry room and a basement.
The unit does not have doors, so it is not the right choice for items you want hidden or locked. It also has no stated fixing method for a wall, so keep it on a level floor and load the heaviest tote on the lowest shelf. For a close alternative with a metal frame and a higher total rating, look at the REGILLER rack. For a cabinet with doors, the Rubbermaid unit is the right choice.
Mistakes to avoid
The first mistake is confusing a total rating with a per-shelf rating. The Sterilite unit lists 200 pounds for the whole unit and 50 pounds for each shelf, while the REGILLER rack lists 500 pounds as a total static load. Check which figure a listing gives and plan within it.
The second mistake is buying a cabinet without measuring its door swing. The Rubbermaid doors need room to open, and the cabinet’s depth of 18 inches needs clear floor in front. Measure the opening and the floor before you order.
The third mistake is putting a lightweight cube unit where heavy items will sit. The C&AHOME listing gives 11 pounds per cube, so keep tools, paint and bottled liquids on a sturdier unit.
The fourth mistake is ignoring the lock. The Rubbermaid listing says the lock is not included, so a lockable cabinet is only as useful as the lock you add. For chemicals and tools, buy the lock before you load the cabinet.
FAQ
What is the best indoor storage unit for a laundry room?
A plastic shelving unit suits a laundry room. The Sterilite four-shelf unit is listed at 34.5 inches wide with four solid shelves, and it snaps together without tools.
Can I store chemicals in an indoor storage unit?
The Rubbermaid listing says its doors lock to keep chemicals away from children, but it says the lock is not included. Store chemicals in a locked cabinet, keep them in their original containers and check the label on each product.
How much weight can an indoor shelving unit hold?
The figures differ. The REGILLER rack lists 500 pounds total, the HOMEDANT unit lists 264 pounds, the Rubbermaid cabinet lists 336 pounds, and the Sterilite unit lists 200 pounds total with 50 pounds per shelf. The C&AHOME cube unit lists 11 pounds per cube.
Do these units need tools to assemble?
Most are tool-free or boltless. The Rubbermaid, Sterilite and HOMEDANT listings describe snap-together assembly, and the REGILLER listing says no tools are needed. The C&AHOME cube unit uses a wooden mallet and the included connectors.
Are plastic units safe for food storage?
The Sterilite listing says its plastic is BPA-free and phthalate-free, and it describes the unit for household storage. It does not describe the unit as food-safe, so do not place food packaging directly on a shelf unless the seller states that use.
Which indoor unit fits a small room?
A narrow metal rack such as the REGILLER unit, with a footprint of 11.8 by 16.6 inches, suits a small room or the corner of a room. The Whitmor unit, at 14 by 15 inches, also fits a small footprint.
Bottom line
Choose an indoor storage unit by its room and load. For hidden or locked storage, use a cabinet with doors. For a plastic utility shelf, use a four-shelf unit. For bedroom or office cubes, use a light unit and keep heavy items off it. For heavy bins and tools, use a metal rack with a stated total rating above your load. If a figure you need, such as a lock or a per-shelf limit, is not included or not stated, check the listing before you buy.
