Many of us covet Costco for bulk deals on food, but neglect to explore the other half of the store. Over there, the aisles are packed with home-improvement supplies, tools and other items which make Costco great for DIYers.
“There are few retailers out there who can sell smart, allow you to stock up, and still let you save real money,” says roofer and remodeler Aaron Jakel. “Costco is one of those stores.”
Also, given the retailer’s lenient return policy and seasonal deals, “Costco offers robust value to both DIY-ers in need of occasional use items or professionals that need to stock up their garages,” adds real estate investor Zack Moorin.
But, while the combo of food and home improvement supplies makes for an easy one-stop shop, there are also a few DIY items to avoid. We asked 10 home-improvement experts to share their favorite items at Costco for DIYers, as well as which ones to avoid. Here’s what they said.
Tools and Hardware
Costco excels with tools like drills, screwdrivers, wrenches and socket sets. Look for Costco, DeWalt and Craftsman brands, says Jakel. “They carry durable steel, offer sufficient torque and come in complete sets without an excessive markup on the name brand.”
Home remodeler Danny Niemela also likes Costco’s bundled tool kits. “It’s a no-brainer for a garage setup,” he says. “You get a lot of tools, all with good-enough quality. It’s exactly what the average homeowner needs for weekend projects.”
Stick to tool brands you’ve heard of, says contractor Lewis Johnson, and keep receipts in case you need a warranty. Also, look for deep discounts on periodic overstock items, like shop vacs and snow blowers, says homebuilder and renovator Tyson Parker.
Workshop Essentials
Our experts recommend Costco for toolboxes, rolling tool carts, workbenches, folding tables, heavy-duty shelving, storage cabinets, air compressors, shop vacs and ladders. “Their LED shop lights are some of the most bang-for-your-buck,” says Niemela. “For about $25, you get a bank of shop lights that will illuminate a two-car garage without a single flicker.”
Costco also excels with essentials like extension cords, tape measures, utility knives, levels and batteries. Cleaner Andriy Neborak chooses Costco for Shark and Dyson vacuum cleaners, plus Rubbermaid mop and wringer systems, while landscaper Steve Corcoran appreciates their spades, rakes, pruners and lawn aerators.
Home Improvement Supplies in Bulk

Especially if you’re undertaking a big project, deals from Costco for DIYers include disposables like sanding disks, shop towels, tape, caulk, sponges, adhesives, wood filler, fertilizer, grass seed and WD-40. “We burn through items like this quickly, so buying reputable brands at a low cost per unit is ideal,” says contractor Lewis Johnson.
Jakel estimates that bulk buying drops his costs by 25 to 30 percent. “It also allows you to complete projects without running out halfway through, which really does save money and time in the long run.”
Plumber and HVAC specialist Megan Doser also likes Costco for basic bulk items. “Even if they are not of perfect quality, it rarely turns into a real problem.” But, she recommends buying from specialty suppliers for complex, precision and heavy-duty items.
Niemela also warns against buying paint, patching compounds and fasteners at Costco. “Chances are, you will end up sacrificing quality or mismatching, costing you double in remedial work,” he says.
Safety and Maintenance Items
Costco offers an excellent selection of safety gear, says Niemela. “They absolutely crush it on N95 masks, hearing protection, nitrile gloves and even disposable coveralls.”
Jakel agrees, adding fire extinguishers and first-aid kits to the list. “Safety gear only works if you have it on hand, so having spares does make a difference.”
Other deals from Costco for DIYers include smoke and CO detectors, work gloves and disinfectants and cleaners, like Simple Green and Clorox.
But “if you need boots or safety glasses, call it a hard pass,” says Niemela. “If comfort and OSHA-grade dependability matter to you, buy these from a professional supply house.”
FAQ
Are Costco tools the same quality as those sold at home improvement stores?
Sometimes. Costco sells many reliable brands, including DeWalt, Craftsman, Bosch and Milwaukee. But just because they’re the same name brand doesn’t always mean they’re the same quality, says Niemela. “Costco often works with brands to create an exclusive or private label that hits their price point,” he says. “You may not get as much steel in the chassis, fewer features, or a pared-down warranty. But it is a good value for the average DIYer, just not the full-time pro.”
Are Costco’s prices on hardware and tools always cheaper?
Nope. “Their pricing is strong, but it’s not always cheaper than Lowe’s or Home Depot, plus Costco rotates its stock, so tools might not always be available year-round,” says Tucker. “Still, the return policy alone makes Costco worth it on the big ticket items.”
Also, keep in mind that buying in bulk does have pitfalls, says Niemela. “Sure, you think you are saving big bucks, but unless you are renovating five bathrooms or rewiring an entire basement, you don’t need 200 feet of PEX tubing or six gallons of floor epoxy.”
