Maximize your backyard organization potential, protect your valuable lawn equipment, and clear out garage clutter with the high-performance Duramax 15 x 8 Apex Pro w/ Foundation (SKU: 40216). Engineered with the structural characteristics of a residential building rather than a standard utility shack, this heavy-duty vinyl storage building delivers massive interior walk-in capacity. Featuring a unique dual-access door layout, it stands as the ultimate, zero-maintenance alternative to traditional wood or rusting metal backyard sheds.
Unlike cheap polyethylene plastic storage structures that warp, crack, and fade over time, the Duramax Apex Pro 15x8 yard shed is constructed using thick, fire-retardant premium vinyl resin panels. These thick cladding sections are structurally anchored by a hot-dipped galvanized steel interior grid consisting of heavy-duty columns, beams, and roof trusses. This hybrid engineering guarantees that your storage building will never rust, dent, rot, warp, peel, fade, or support mildew growth, while providing a completely safe space to store flammable items like lawnmowers and fuel canisters.
Premium Structural Engineering & Design Benefits
-
Zero-Maintenance Architectural Build: High-quality vinyl resin panels require absolutely zero painting, staining, sanding, or seasonal weather stripping. Simply spray down with a garden hose to preserve its clean exterior appearance.
-
Dual-Side Double Door Accessibility: Built with an advanced multi-door layout featuring both extra-wide front double entry doors and double side pedestrian doors. This allows you to easily load, organize, and retrieve lawn equipment, bicycles, or patio furniture from either side of the structure.
-
Abundant Natural Sunlight & Cross-Airflow: Outfitted with 2 creatively designed integrated roof skylight panels and 2 clear front windows for optimal natural light control, paired with 4 slotted ventilation grids that maximize air circulation to reduce heat and moisture.
-
Heavy-Duty Galvanized Foundation Framing: Comes standard with a structural steel floor grid kit, ensuring a perfectly stable, level foundation base when completed with your choice of exterior-grade plywood or a solid concrete pad.
-
Integrated Tool & Shelf Mounting Columns: The heavy-duty interior steel columns are engineered with integrated mounting points, allowing you to easily hook up garden tool racks, hang extension cords, or bolt-on heavy shelving kits to maximize vertical space.

No floor included.
This model incudes a foundation kit similar to the floor joists that a house is built on. After the shed is assembled then most people lay down sheets of plywood on top of the foundation kit to use as a floor. -
When do you think this shed will be back in stock?
At this time we have no information as to when it will be back in stock. If there is no date listed on the product page then we cannot even accept back orders. I suggest checking back on the website every week or so and when you see a back in stock date go ahead and place an order even if it is a back order. Sometimes when these sheds come back in stock the supplies are limited and they sell out again quickly.
-
Can the foundation be used on an existing concrete slab?
Yes, and it should be.
-
What does the foundation kit include?
Steel tube framework similar to floor joists in ahouse on a crawl space. It is shown in one of the pictures on the product page where the doors are open.
-
Can a floor be installed or do you sell a floor for the Apex Pro?
We do not sell a floor, however in the assembly instructions it gives you two options. Either a pattern to cut sheets of plywood for a wooden floor or a concrete floor.
