    Lifetime outdoor storage sheds are built to last! MADE IN THE USA. Through exhaustive consumer research and studies of the competition, Lifetime discovered that all vinyl sheds have a few great features, but significant weaknesses. We eliminated all of those weaknesses and combined the best features into one complete package.

    Lifetime outdoor storage sheds are double wall-steel reinforced and built with the finest polyethylene parts. All exposed steel parts and trusses are powder coated and they only use high impact polyethylene. Polyethylene has superior strength and durability and it won't degrade outdoors as well as they won't crack, dent or mildew. They make great Tool Sheds, Garden Storage Sheds, and just Great Outdoor Vinyl Storage Sheds. Backed by a 10 year warranty, Lifetime sheds are without a doubt, the BEST OUTDOOR VINYL STORAGE SHEDS made today.

    Consult local building codes before assembly. This shed must be built on a flat level foundation of wood or concrete (not included). Flooring must be anchored to the foundation. Anchoring hardware depends on the type of foundation you have and is therefore not included in the shed kit. Not including the installation of the foundation, you can expect assembly of the shed itself to take 2 adults up to 8 hours.
