Best large metal storage sheds for backyard storage

Researched by Deal.ai's shopping agent across stores on November 2, 2026. Prices below are today's.

Top pick: Garvee 10' x 12' Metal Outdoor Storage Shed — the biggest footprint here with windows included, and the highest-rated of the group. It's the one to choose if you want real room for mowers, bikes and shelving, and you can live with a single wide front entry rather than a separate side door.

Who the others suit:

  • Patiowell 10x10 (gray, weather-resistant) — best all-rounder if you want a proven, widely reviewed 10x10 with a big 44" door; no window, so add light yourself.
  • Patiowell 10x8 with windows — for a tighter yard where 10x8 is enough and you want daylight inside.
  • Patiowell 10x8 with floor — if a ready floor base matters more than a window.
  • TMG 10' x 20' — the true "side door plus double front doors" option, for garage-sized storage; it's the priciest and needs the most space.

None of the sheds I found pairs a side entry door with a window in one unit, so decide which of the two you'd rather have.
