5 Bulky Costco Products That Are Driving The Company's Success

Although Costco may be best known for low prices on rotisserie chicken, bulk toilet paper, and food court hot dogs, the store's offerings are much broader. Costco expanded its money-making practices by offering membership upgrades, showing targeted third-party website advertising, and even selling millions of dollars in gold bars — and that's still not everything that the discount brand is doing to increase revenues and profits. The store has also gone big and bulky, a term the chain reserves for oversized items like recliners, stoves, and exercise bikes. Many of these products are being bought by customers online thanks to the convenience offered by the company's delivery service, Costco Logistics, which can hand deliver larger products and even take away the older items they're replacing. Meanwhile, shoppers used to the traditional practice of making a trip to their local Costco may also notice larger items taking up more of the floor space in stores as well. In short: Costco is making efforts to sell bigger pieces, and it's easy to see why. 

A key benefit to larger items is that they come with bigger margins. However, with such a wide-ranging inventory, the big box store must perform something of a balancing act to prevent customers who appreciate buying groceries, cleaning supplies, and hygiene products from changing their perception of the value Costco provides when they start seeing larger items in stores. Luckily, there's a wide selection of big and bulky products that are already contributing to Costco's coffers in a positive way.

As of December 2025, Costco offers furniture for living rooms, bedrooms, kitchens, dining rooms, home offices, and children's rooms with a wide range of prices. As examples, shoppers could buy a Thomasville Miles Fabric Sectional with Power Footrest for $1,199 or a Malibu Four-Piece Leather Power Reclining Sectional with Power Headrests for $5,799. Those furnishing bedrooms could opt for a Marina Del Rey Bed for $999, or an entire Wales King Bedroom Collection for $7,399.

Because it's typically more practical to have furniture shipped rather than taking it home yourself, buying these items can mean shifting to Costco's online store. Although this is becoming more common across age demographics, YouGov dubbed Gen Z as the online shopping generation. An internal survey found that 39% of Gen Z shoppers buy products digitally. This dovetails well with membership evolutions at Costco, as CEO Gary Millerchip told CNBC the average age of members has dropped: Almost 50% of new signups come from people under the age of 40 as of summer 2025. As more and more Gen Z shoppers enter the workforce and move into their own places, they could theoretically furnish them completely through Costco without ever going to a store — although some of them may find reasons not to buy or renew their Costco membership because non-members can purchase many online deals at a slight upcharge. Even so, if Costco continues making essentials like beds conveniently accessible and affordable, it will almost guarantee itself a customer base in this sector.

Whether you're looking for washing machines, dryers, dishwashers, microwaves, ovens, freezers, or wine coolers, Costco has your appliance needs covered. Although items online are often available to both members and non-members, the brunt of Costco's appliance section was labeled "Members Only" as of December 2025, requiring shoppers to enter membership data to see pricing and make purchases. This included a Frigidaire Professional 28-cubic-foot Standard-Depth French Door Refrigerator for $2,049, and a GE 30-inch 5.0 Cubic-Foot Gas Free-Standing Range With Central Oval Burner for $979.

Bulkier appliances aren't the easiest thing to move on your own, which may incentivize shoppers to buy their next fridge or dishwasher online. Costco also offers free installation of these items in many areas, saving customers the time and hassle of setting them up themselves. Of course, many locations do display these items in the store as well, so you could still conveniently stock up on groceries, jewelry, or electronics the same day you decide to scope out your next oven. Customer loyalty is a key reason why Costco sales keep growing, and this versatility is as appealing to many Costco members as the bulk pricing. Whether or not this has played a role in an increased share of big and bulky items purchased from Costco's online marketplace, CNBC's report on the company's fiscal Q4 earnings call revealed online sales increased by over 13%. Meanwhile, the previous quarter saw a 31% boost in Costco Logistics use, suggesting significant engagement with large item deliveries.

For the aspiring musician in your life, Costco offers a range of instruments at a wide array of price points. Its piano and keyboard selection is particularly robust, with items like the Artesia Pro A100 High Gloss Ebony Digital Piano going for less than $1,000, while higher-end alternatives like the Roland CG-1 Mini Grand Digital Piano Bundle run for as much as $5,499. The store also sells drum gear, karaoke equipment, and even amplifiers, some of which list at very entry-level price points. Aspiring drummers might find the Roland V-Drum Kit — TD-07KX a solid deal at $1,499, while more experienced players might gravitate toward the more versatile Roland TD-513 Electronic Drum Kit priced at $2,699. When it comes to outdoor recreation items, CNBC reports Costco CEO Ron Vachris said that $1,200 swing set sales were "blowing out expectations" in 2024, and the company also sells luxury items with higher price points like the Whisper W5XL Six-Seat Off-Road Recreational Golf Cart for $10,299.

Selling items that appeal to shoppers with such different budgets — as well as those at different stages in their lives — ensures that a Costco membership could be a sound investment for all kinds of people. Whether you're a master of your craft, interested in a new hobby, or simply a parent trying to get your kids outside, Costco could be a viable stop for your next big purchase.

As of December 2025, Costco offered 17 sauna models with prices ranging from a couple hundred dollars to well into the thousands. More casual steamers on a budget could access the Homedics Saunazen Portable Steam Sauna for just $239, while the Dynamic Saunas Monaco Six-Person Ultra Low EMF FAR Infrared Sauna could make a luxurious addition to your home for $8,999. Saunas serve as an excellent example of big and bulky items almost exclusively sold online. At the time of research, only one model was available in some stores: the Homedics Portable Premium Steam Sauna model available for $299.

Because of limited warehouse availability, this product line strongly contributed to the over $19.6 billion worth of e-commerce sales over Costco's 2025 fiscal year, as reported in the Q4 earnings call. This serves as a 15% year-over-year increase with online purchases accounting for more than 7% percent of total sales, per CNBC. Big and bulky items likely also contributed to the global increase in transaction size of 2.6%. Much like with other recreational equipment, Costco's sauna selection lowers the barrier for entry on an experience that would otherwise be reserved for the select few who could afford it. This approach to its inventory invites all kinds of people to experience the full range of what Costco has to offer its members, as its increased sales reflect.

Big and bulky items are helping to get Costco in even better shape, and the company sells plenty of products that can help its customers do the same: Some highlights in this sector include the Xterra Fitness TR85 Folding Smart Treadmill for $1,299 and the Kingsmith Tri-fold Water Rower for $579, though fans of exercise bikes, Pilates machines, ellipticals, home gym systems, workout recovery items, dumbbells, weight sets, and gym flooring could all find their needs met at Costco. Besides earning revenue and profit from them, this provides Costco with an excellent opportunity to cross-sell men's and women's activewear, wearable technology, headphones, earbuds, sports nutritional supplements, whey protein, and healthy foods.

With recent enhancements to its targeted advertising and online marketplace, Costco has ample opportunity to present customers with other products that could be relevant or outright beneficial to their bulkier purchases. These efforts can entice customers to make more purchases online to a similar effect that displaying related products near each other on store shelves might entice visitors to pick up more items as they walk through aisles. According to marketing company Wiser Notify, cross-selling and upselling to new and existing customers can create a 42% boost in revenue. Although that can make a significant difference in businesses of any size, it's exponentially more important with a company as large as Costco. It's strategies such as these that inform why Costco has already reported its sales hit $65.98 billion in the first quarter of its 2026 fiscal year.
