Lifetime 8 x 20 ft. Shed – 60120

146.4 Sq. Ft. of Storage in an 8×20 Storage Shed

This 8×20 storage shed gives you 869.5 cubic feet of enclosed space with 6 ft. 8 in. of headroom to walk around comfortably.

Picture your riding mower, bikes, patio furniture, and seasonal gear all under one roof, organized on height-adjustable shelving instead of piled in a corner of your garage. Natural light pours in through four skylights and two interchangeable windows, so you can actually see what you’re reaching for.

Built to Outlast the Weather as a Dual Wall Storage Shed

Steel-reinforced HDPE panels form a dual wall storage shed that resists dents, rust, and rot — no scraping, sanding, or repainting required.

- Lockable Steel-Reinforced Doors — worried about break-ins? An exterior padlock loop plus two interior deadbolts keep your gear secured (padlock not included).
- 4 Panel Skylights — tired of fumbling in the dark? Natural light floods the interior so you can find tools without running an extension cord.
- Height-Adjustable Shelf — need flexible storage? Reconfigure shelving as your stuff changes size and shape.
- UV Protected Exterior — afraid of fading and cracking in the sun? This HDPE storage shed stays weather-tight year after year.
- High-Pitched Roof with Steel Trusses — dread snow load damage? Rain and snow drain quickly while trusses add serious roof strength.
- Slip-Resistant HDPE Floor — worried about oil stains or cracking? The included floor resists solvents, stains, and impact.
