Some storage shed styles available at Costco are the side entry shed, horizontal shed and the wood storage shed. The most well-represented storage shed manufacturers at Costco are Lifetime and Yardline, as of 2015.
The storage sheds range in size between 75.2 inches long by 42.2 inches wide by 52 inches tall for a Lifetime horizontal shed, to 11 feet wide by 21 feet long by 9 feet tall for a Lifetime garage shed. The Lifetime horizontal shed is the highest reviewed shed on Costco.com and is rated four out of five stars. Reviewers refer to the shed's large storage capacity and appearance as its best qualities, while also stating that the shed's included assembly instruction manual could be clearer.
The Lifetime garage shed is constructed from high-density polyethylene plastic and steel, and comes equipped with tri-fold doors that allow owners to open the entire front of the shed. The garage shed has favorable reviews on Costco.com, where it is ranked three and a half stars out of five. Many reviewers point to the shed's poor quality and difficulty to assemble as the reasons for low ratings.
Most of the sheds sold by Costco are of the standard front swing door design. However, the Lifetime Brighton side entry shed is one of the few storage shed options that boasts two entryways. In addition to the standard front entryway, the shed also has a side door to further facilitate easy access.
