The Best Costco Storage Shed Based On Reviews

If you're looking for outdoor storage, a shed could be the ideal solution. However, choosing the perfect storage shed can be difficult. You often have to decide between wood and resin materials, both of which have their pros and cons. But Costco has plenty of available options to choose from and, from looking at reviews, the best shed for purchase is the Suncast 6' x 5' Modern Shed. It has over 2,000 reviews, fits into a variety of budgets, and boasts enough space to store a good amount of outdoor items. It's also made of resin, so you'll rest easy knowing it's weather-resistant. 

When choosing between shed materials, consider what you're looking for. Resin sheds have numerous pros, from ease of assembly to fire resistance (to name a few). Wooden sheds, on the other hand, are incredibly durable and customizable. If you want a shed that aesthetically matches your home, then wood could be ideal. However, wooden sheds are more expensive than their resin counterparts, which can be an issue. 

But that cost can be worth it because wooden sheds can last for decades, while resin sheds last upward of only seven years, as plastic eventually cracks. If you want an environmentally friendly shed, then resin might be your best bet. If you're looking to build an affordable storage shed, Costco has an option in your price range. Here are the top contenders based on reviews.

Wood storage sheds

The Yardline Crestwood 14' x 8' Wood Storage Shed seems to be a great option. It boasts 647 reviews, with one customer explaining "It's great that everything comes pre-cut, which is a real time-saver. The instructions are clear and detailed." This shed costs $3,000 and is only purchasable online. The Yardline Crestwood offers 934 cubic feet and comes with a storage loft, two shelves, a floor kit, two windows, and pre-assembled doors. You just need to paint it and add shingles of your choosing. If you live in Florida, however, Costco can't ship this item to you.

Another option for anyone who loves a DIY project is the Yardline Aston 10' x 7.5' Wood Shed. It's smaller than the Crestwood, so it's ideal for smaller spaces or small- to medium-sized garden tools. It's 565 cubic feet, is also pre-cut, and comes with a floor kit and two doors. It has a window and two wall vents to prevent moisture from building up within it. As with the Crestwood, you need to purchase paint and shingles for this model. This shed has 409 reviews and one person said, "Overall this is a nice shed and it's pretty roomy inside." Even if you need more room in your shed, you can maximize the storage space with DIY projects.

Resin storage sheds

Resin is known for its resistance to fading, rusting, rotting, fire, bugs, and more. Even though it's small, the Suncast 6' x 5' Modern Shed is a crowd-pleaser. It has over 2,000 reviews and 4.5 stars. According to one customer, "We just bought this shed and assembled on the weekend. We put it together in an afternoon. It looks great, was easy to assemble, and has plenty of head room inside for someone over 6ft." Before you start shopping, however, familiarize yourself with tips on how to choose the right size storage shed for your backyard. If this 200 cubic-foot shed works for your space, you can purchase it online for $800. It's perfect for patio cushions, gardening equipment, bikes, toys, bins, and more. Since it's made from resin, it features all-weather construction. It just requires a strong foundation, which you need to provide. But resin is low-maintenance, so you don't need to paint this shed, unlike its wooden counterparts. 

Another great resin shed is the Keter Newton Large Premium Outdoor Storage Shed. It costs $1,400, is only available online, and requires assembly. This shed has 163 reviews, with one consumer saying "This is of good quality, looks great, and is not difficult to assemble." The great thing about this particular shed is that it's also weather-resistant, reinforced with steel for extra durability, constructed of maintenance-free polypropylene resin plastic, and has two windows, skylights, and vents. No matter what you choose, be prepared to assemble your shed.
