Item #1432238 | Suncast 6′ x 4′ Vertical Storage Shed | 106 Cu Ft | $399.99 (no longer available in-store — see alternatives below)
The Suncast Vertical Shed was one of Costco’s most popular seasonal outdoor products. It hit the shelves every late winter and early spring, and it sold out every time. Costco priced it at $399.99 — significantly cheaper than the $500-550 you’d find at Home Depot or Lowe’s for the same shed.
I own 2 Suncast products and they’ve been sitting outside in Bay Area sun, wind, and rain for years. Still look almost brand new. No fading, no warping, no maintenance. If you’re looking for a vertical storage shed and missed it at Costco, here’s everything you need to know — plus where to buy one now.

What Made This Shed Popular at Costco
The Suncast Vertical Shed solved a simple problem: outdoor storage without the commitment of a full-size walk-in shed. It’s a tall, slim, double-door resin cabinet that fits against a house wall, fence, or garage side — storing everything from shovels and rakes to pool gear and seasonal decorations without eating up your entire yard.
At Costco’s $399.99 price tag, it was $100-150 cheaper than the same product at any big-box hardware store. Pair that with Costco’s return policy and it was an easy decision. That’s why it sold out every season.

The resin construction is what sets Suncast apart. It doesn’t rust like metal sheds, doesn’t rot like wood, and doesn’t require painting, staining, or sealing. Ever. You assemble it, anchor it to a flat surface, and forget about it.
Assembly
Assembly takes 2-4 hours and is significantly easier with 2 people. No specialty tools needed — a Phillips screwdriver and a rubber mallet are all you need. The panels snap and screw together following the included instructions.
The most important step: get the base level. A crooked base means crooked walls and doors that won’t close properly. Take your time on the foundation — concrete, pavers, or compacted gravel all work. Bare dirt or grass will settle unevenly over time and cause problems.
Other assembly tips: lay out all panels and hardware before you start so you’re not hunting for pieces mid-build. Don’t skip the anchoring step — the shed is lightweight relative to its size, and wind can tip an unanchored unit. Suncast includes anchoring hardware but the surface underneath needs to be solid.
Long-Term Durability
I’ve had Suncast products outside in the elements for years. Sun, rain, wind — they’ve handled everything without fading, cracking, or warping. The resin panels are genuinely maintenance-free. I’ve never treated them with anything — just an occasional hose-down to clean off dirt.
Other long-term owners report similar results. The shed holds up well for 5-10+ years with zero maintenance. The most common issue is door latches loosening over time — a 5-minute fix with a screwdriver.
The resin is UV-resistant but not UV-proof. After several years in direct sunlight, some minor color fading can occur. It’s cosmetic only and doesn’t affect structural integrity. Position it where it gets some afternoon shade and it’ll look newer longer.
Who This Shed Is For
Homeowners with limited yard space. The 44-inch depth fits against a wall without protruding into your yard. Perfect for narrow side yards, patios, and garage-adjacent spaces.
Anyone replacing a rusted metal shed. No rust, no leaks, no sharp edges, no painting. Solves every problem metal sheds have.
DIYers and gardeners. The vertical design is built for long-handled tools — shovels, rakes, brooms, trimmers, and hedge clippers all fit standing upright.
Anyone who doesn’t need walk-in access. At 44 inches deep, you’re reaching in, not walking in. If you need to store a riding mower or large power tools, look at a full-size walk-in shed instead.
Costco Availability
This shed is no longer available at Costco as of 2026. Costco carried it seasonally for several years at $399.99 (Item #1432238) and it was occasionally marked down to $299.97 on clearance. Costco currently carries updated Suncast models on their website starting around $499.99, but the original 6′ x 4′ vertical shed at $399.99 was the best value version.
