Buying a Portable Generator Shed – Lifetime Horizontal Shed


I used to keep my Briggs and Stratton Storm Responder 5500 on my deck, tucked in a corner covered with a sliver of plywood. The cover “roof” did little to protector the generator from driving rain and snow and I think my generator did not appreciate it very much based on surface rust, hose degradation, etc.

I built a custom shed (you can read it here) but I realize that not everyone has the space or time to custom build one so I am reviewing 3 most popular tool sheds that can be re-purposed into a portable generator shed.

TLDR; Which one should I buy?

I am definitely biased towards Lifetime products based on my past personal experience (read about my Lifetime deck box review here).

It is built like a tank and little has changed in 6 years of use. And it is Made in USA to boot! I also like Suncast products, though they are not made in USA.

Lifetime Products Lifetime 60170 Horizontal Storage Box

Lifetime Heavy-Duty, Horizontal HDPE Storage Box (click to check model # 60170 or 60088) is a high quality beast. It is absolutely huge in comparison to others generator sheds, coming in at approximately 52″ height x 41″ depth x 74″ width, providing almost 75 cubic feet of storage space.

Weighing at almost 150 pounds, the rigid dual-wall high-density polyethylene (HDPE) construction makes the shed strong, durable, and sturdy and much like my Lifetime deck box, the horizontal storage shed is UV-protected construction and weather-resistant design to keep your content away from moisture and other elements.

Although it was originally designed to hold two large garbage cans, a large interior capacity allows you to conveniently store and operate your portable generator with ease.

Lifetime Horizontal Shed is durable and reliable choice (won’t rust, chip, crack or splinter) to store your generator and keep away from outdoor environment. With a lift-up top lid that is spring-hinged for easy, immediate access and lockable double front doors swing open nearly 180 degrees, you can have complete access to your portable generator.

** Just a quick note that two lid supports (spring design) will gradually wear out but the replacements can be purchased via Lifetime Products Customer Support (800.225.3865 or [email protected], 7am-5pm MT M-F and 9am-1pm MT Sat)

Lifetime Storage Box comes pre-finished with light-sand colored walls and doors, with complimentary dark-brown lid for both 60177 and 60088 models.

It is straightforward to assemble, though plan on taking your time when assembling by yourself (take special care when connecting he top lid hinges):

  • Tape measure;
  • Cordless drill (90 degree angle cordless drill will come handy);

It is worth noting that a portable generator should be rolled completely out of the shed before using. These generators need full access to open air to properly ventilate and dissipate CO and other exhaust. Also, the shed should be placed 25' or more from the house. or the generator will have to be rolled out that distance away to avoid CO from infiltrating the house interior. .
