11 Space-Saving Storage Shelves Costco Shoppers Recommend

There are many unique and functional shelving ideas that can help you to organize your home. But if you invest your hard-earned money in a poor-quality set of shelves, you can easily set yourself up for failure before you even remove them from the box. Over at Costco, there's no shortage of shelving solutions. And if you look online, you'll notice that there's no shortage of customer feedback, either.

To help you make sense of it all, we've combed Costco's online shelving section to see which products are the most highly recommended by buyers. Some are designed for heavy-duty garage storage, others make excellent partners in the pantry. Some are designed for portability, while others yield thousands of pounds of storage capacity, which is sure to help declutter even the most disorganized garage. You'll find out more about our methodology at the end, but for now, just know that all are rated at least 4.6 stars overall, with at least 130 real user reviews.

Whether it's in your kitchen, bedroom, dining room, or garage, one of the best ways to maximize open-shelving storage space is to incorporate baskets. These keep more unwieldy items contained, while retaining a clean, clutter-free look on your shelves. In the case of Trinity's EcoStorage 5-tier Shelving with Baskets & Dividers, those baskets are built into the unit. Priced at $249.99, it's especially useful for keeping pantries organized, with customizable dividers enabling you to further tailor your storage.

This set is also NSF-certified. That means that the materials conform to food equipment safety and sanitization standards. It's also rated 4.9 stars overall, with 96% of more than 170 reviews awarding it top marks. And while some have used it for their pantry as suggested — including one who said that it's helping them to live their MasterChef fantasy — that's not the only way it's proven useful. "I'm using this for clothes," said another user. "I can see everything and reach it. So organized. I got rid of 3 large dressers, I can now walk around my California king bed with room to spare."

If you're trying to choose the best shelving set for a kitchen or walk-in pantry, then form and function are both important. So, too, is the material. Like the brand's shelving set with built-in baskets, Trinity's 5-tier Wire Shelving Rack is NSF-certified, meaning it's made from food-safe materials. Priced at $129.99, it features five shelves, each of which can bear up to 160 pounds of weight. The shelves are also height-adjustable in 1-inch increments.

This set is a quality choice for buyers who already have baskets to load it with. The unit comes supplied with four caster wheels, which is useful for moving it around and maintaining a more versatile workspace. However, if you decide to remove them and instead mount the unit on the four supplied leveler feet, its total weight capacity shoots up from 800 to 2,500 pounds. This product is also very highly recommended. In fact, of more than 220 reviews to-date, 92% have awarded it full marks. It's rated 4.8 stars overall, with buyers having praised its utility for storing various items, from 3D printers to pots and pans. "Very happy with these shelves," said one. "They were super easy to put together, and seem to be able to hold a ton. Totally worth it to get organized."

Garage organization doesn't have to cost a fortune, especially if you have the skills and tools to DIY your own storage. But is it really cheaper to build your own garage storage shelves? That depends on how sturdy you need them to be, the materials you want them to be built from, and the level of craftsmanship you're able to bring to the project. At Costco, Gorilla Rack's Industrial Shelving is currently priced at $279.99, which may be pricier than a DIY job. However, it comes with the added benefit of Gorilla's limited lifetime warranty. The price tag also buys strong, welded frames, which between them can carry up to 2,000 pounds of tools and equipment. A powder-coated finish resists scrapes, scuffs, and dents. And if you buy multiple racks, they can be installed together to organize a larger garage.

So far, the set has been reviewed by more than 3,630 users, and of those, more than 91% have awarded it 5 stars. It's rated 4.8 stars overall, with several customers explaining that the product is easy to assemble, strong, and worth every penny. As one user put it, "No, they are not cheap. But if you want quality and confidence in your shelving holding up for the long haul, these are the ones to buy!"

One nifty way to declutter your kitchen countertops is with the addition of a storage cart. These storage contraptions provide the extra space you need to store your go-to cooking utensils and appliances without soaking up too much counter space. And since they're mobile, you can wheel them out of the way when you need more room, like when you have guests. They're similarly useful in the garage, providing a mobile caddy for tools and allowing you to wheel your most unwieldy equipment to wherever you need it. Trinity's EcoStorage 3-tier Cart is designed with such uses in mind. Like the other Trinity products featured so far, it's made from food-safe materials. As for capacity, each shelf holds up to 266 pounds, lending to an overall capacity of approximately 800 pounds.

The cart currently fetches $79.99, and as for reviews, it earns a 4.8 star rating overall. More than 690 users have reviewed the cart to-date, with 90% awarding it top marks. As for why, most agreed that it's both heavy-duty and easy to wheel around. Some even explained that they use it to help unload their regular Costco grocery shopping from the car. "I am very happy with this versatile cart that I bought for extra storage in my garage," said one buyer, who added, "It's solidly built — no wobbling." Another, who bought the cart for their bakery, said, "We have four of these carts. They are heavy duty and move easily even when fully loaded. We're always moving heavy items around the bakery and these work perfectly. They also happen to be the exact height of our work tables, so if we need a "table extension," we just pull a cart next to the table."

There's a reason why wire shelves show up in almost every organized garage. Their simplicity is what makes them so useful. You can loosely place items on the shelves, or you can use them to house your toolboxes, baskets, and totes. Of course, depending on what you need to store, you need to ensure your shelving of choice is capable of carrying the correct amount of weight. This 5-tier Heavy-Duty Wire Shelving Rack is the strongest shelving set from Trinity in this guide. It can bear up to 4,000 total pounds of belongings, making it useful for tools, hardware, and other heavy items that might otherwise clutter up your garage floor. It features five shelves in total, with height-adjustable tiers that can be tailored to hold items of various heights. You can mount it on either levelers or on casters, just note that the overall weight capacity reduces if you opt for casters.

It's rated 4.8 stars overall, which is solid. It's even more impressive given that more than 2,230 users have reviewed it. 89% of those have awarded it top marks, with plenty enjoying how the set has helped them give their garage an organizational makeover. As one user said, "This was such a good purchase that I have ordered and assembled a second one! My garage floor has been transformed from a messy pile into an organized, easily accessible storage system."

Similar to Trinity's rolling cart, this 5-Tier Rolling Bin Organizer from Gorilla Rack can be wheeled to wherever you need it. It's mounted on four heavy-duty casters, two of which can be locked to ensure it stays where you left it. Per Gorilla, it's ideal for substantial storage needs in small spaces, holding up to five 27-gallon totes, or ten 12-gallon boxes. A powder-coated finish protects the frame from corrosion, while heavy-duty welded-end frames lend it both strength and durability. For added reassurance, the product comes with a limited lifetime warranty.

To-date, more than 350 buyers have tried and tested the shelving unit, and out of those, 88% have given it 5 stars. Overall, it's rated 4.8 stars, with easy assembly, mobility, and durability all earning it points in the reviews. It's also popular with buyers who appreciate the benefits of plastic bin storage, including one who liked the set's compatibility with the storage bins sold by other brands at Costco. "This sturdy rack is exactly what we need," said one happy buyer. "It fits in a fairly small space, but has lots of storage ... And the option to use either the larger or smaller bins works great for us."

Another storage solution from Trinity, this 5-tier NSF Rack with Pull-Out Baskets is tall, not wide, making it ideal for storage in otherwise-unused corners around your home. It makes items easier to access with pull-out baskets, which, being baskets, also help to store awkward items without the risk of them spilling out. It also features a hook rack, which you can use for hanging your trusty hand tools. Alternatively, you could use it for hanging pots, pans, and other kitchen utensils. The material is NSF-certified, meaning it's safe for use in food preparation environments.

Rated 4.8 stars overall, the rack has been reviewed by more than 1,180 users to-date, 87% of whom have awarded it 5 stars. Buyers have cited various reasons for their feedback, including its utility in small spaces, especially in corners, as well as its adjustability (its shelves can be height-adjusted in 1-inch increments). "After researching different racks for our needs, we picked this one because of the width and the pull out storage baskets," said one. "It's a perfect fit for our pantry."

Storage shelves aren't limited to the pantry and garage. In fact, free-standing shelving units can be an excellent way to organize your bedroom without a closet. Trinity's Bronze Rolling Garment Rack features two bottom shelves, for stowing away shoes, clothes, and baskets. It also includes a hanging rail, which you can use to keep your Sunday best crinkle-free. Above the rail is a third shelf, which would be useful for storing occasional items out of the way. Like Trinity's 5-tier EcoStorage rack, it also includes a built-in hook rack, ideal for hanging coats and bags. It's easy to move around thanks to four sturdy casters, two of which can be locked to keep the unit in place.

A 4.8-star overall rating means that it's strongly recommended by buyers. More than 560 have tried and tested the rack to-date, with 87% awarding it 5 full stars. As for why, some users said they were pleased to find that it lived up to Trinity's description of the materials as "industry quality." Others said how useful it is in smaller homes where closet space comes at a premium. As one user said, "I needed more closet space when my mother moved in with me for a few months. This was perfect. It was easy to put together, sturdy, easy to move about, and the shelves give a lot of extra space."

Most of the shelving sets we have featured so far are made from metal, many of which are food safe. Some are also powder-coated, protecting them from scrapes and thus warding off issues with corrosion. Greenmade's 5-tier Utility Rack is also durable, however, because it's made from heavy-duty plastic, no amount of abuse will result in rust. Its weight-bearing capacity is a little lower than others. It totals at 750 pounds, which breaks down to 150 pounds per shelf. It's not as mobile as others, either, as it doesn't include casters. However, it's still fairly robust, and depending on where you plan to put it, you may not actually need to move it once it's in situ. It's also compatible with Greenmade's 27-gallon Storage Bins, which are also available at Costco.

More than 1,060 users have reviewed this Greenmade set so far, and out of those, 86% gave it 5 stars, lending to an overall rating of 4.8. Users have said how sturdy the shelves are despite their lightweight build. The set's easy assembly is also widely noted. One buyer, who purchased three of the sets, said, "I had all of them completely assembled in less than 30 minutes." Another, who said they were hesitant to buy a plastic shelving unit, said, "I bought this to tidy up my garage. I had a bunch of paint cans and various tools that needed a sturdy resting place ... To test it, I stood on the bottom shelf, rated at 150 pounds, and it held my weight of 225 pounds with no problem."

One of the main drawbacks of buying large shelving units is that, while they offer lots of storage, they often soak up lots of floor space. In smaller, more awkward spaces, modular shelving is sometimes preferable to a large, single unit. Trinity's 3-tier Modular Wire Shelving Rack comes with two smaller units, each of a size that's unavailable elsewhere in the range. Each rack is 30 inches tall, 23 inches wide, and 13 inches deep. You can use them individually, place them side by side, or stack them vertically. The sturdy wire construction allows up to 450 pounds load-bearing capacity per unit, which equates to 150 pounds per shelf. Stacked together, the set provides a total of six individual shelves. You can also adjust the shelves in 1-inch increments, depending on the items you need to store.

This combined versatility has earned the set a respectable overall rating of 4.8 stars. Over 130 users have tried the shelves, with 86% awarding it top marks. Buyers have found a variety of uses for the set, too. Some have put it to work in tight spaces, where its ability to stack or provide multiple shelving units makes it extra useful. One buyer bought it to help declutter the counters in their small kitchen, and another used it to add shelving to their space-starved utility closet. In most cases, the reason for their feedback remains the same. As one user rather succinctly put it, "It's a decent quality shelving unit that's reasonably easy to assemble. It does what it's supposed to do."

Similar to Gorilla's 5-tier Rolling Bin, this Storage Bin Rack from SafeRacks is designed for slide-out tote storage. It works with Greenmade's 27-gallon storage bins (also available at Costco), and because they fit onto sliders, you don't have to unstack the entire unit to access the bin you need. It comes with either a zinc-plated or black-powder-coated finish, both of which protect against rust and corrosion. Overall, it can store 250 pounds, and since it's NSF-certified, it's safe for use with food equipment.

To-date, more than 3,380 users have rated the rack, with more than 79% awarding it 5 stars. It's rated 4.6 overall, largely thanks to the set's easy assembly and the ease with which buyers can access their totes thanks to its drawer-style design. One user also explained how the sliders will comfortably fit two half-sized totes, instead of a single 27-gallon bin. "I love this storage system," said another happy user. "They are strong and a good size for our garage. We have four racks ... lined up on one side. Perfect fit."
