The answer depends on the brand: many 10×8 metal sheds like Arrow’s ship without a floor, so you buy a frame kit and deck material separately.
Most 10×8 storage shed buyers assume the floor comes in the box. With metal sheds such as Arrow’s Classic, Select, and Elite lines, that assumption costs you a trip back to the store. Lowe’s product data is blunt about it: these sheds list “Floor Included: No” right on the spec sheet. The shed itself arrives as walls, roof panels, and hardware — the floor is a separate purchase, and the kit only gets you halfway there.
This guide breaks down what each Arrow 10×8 model ships with, what the floor kit actually includes, and how to finish the job so your shed sits level and square for years.
Do Arrow 10×8 Sheds Come With A Floor?
No. Arrow’s Classic, Select, and Elite 10×8 galvanized steel sheds all list “Floor Included: No” and “Floor Frame Included: No” on their Lowe’s spec sheets. The foundation is also not included, so the shed sits on whatever base you prepare.
That’s not a defect — it’s a design choice. Metal sheds need a floor material rated for ground contact, and Arrow lets you pick what works for your site rather than forcing a generic deck. The trade-off is that you must budget for the floor separately before assembly.
Here’s what the three Arrow 10×8 models include per Lowe’s listings:
| Model | Peak Height | Storage Capacity | Door Opening |
|---|---|---|---|
| Classic Galvanized | 6 ft | 432 cu ft | 55.5 in wide |
| Select Galvanized | 8 ft | 496 cu ft | 59.25 in wide |
| Elite Galvanized | 8 ft | 521 cu ft | 63.44 in wide |
All three are rust-resistant galvanized steel, and none includes a floor frame, floor deck, or foundation. If you want a 10×8 storage shed with floor ready to walk on, you either buy the kit plus decking or look at brands that build the floor in.
Where The Floor Kit Gets Confusing
Arrow’s accessory floor kit is compatible with the Classic, Select, and Elite 10×8 models, but the kit is not a complete floor. Lowe’s kit listing says it plainly: “Includes frame only – flooring is not included.” You get the perimeter framing and supports — the wood deck surface is on you.
Before you buy, check which kit matches your model. Arrow’s compatibility notes show Classic 10×8 and Select 10×8 sheds accept the FKCS03 kit, and the Elite 10×8 uses its own compatible kit. Don’t assume one kit fits every Arrow shed — match the model number before checkout.

Leveling The Floor Frame First
Get the base wrong and the whole shed suffers. Arrow’s assembly instructions stress one sequence: level and square the floor framing before you attach any decking.
The manual’s guidance comes down to three checks:
- Check the diagonals — equal measurements mean the frame is square.
- Install one floor panel, then re-check the frame for squareness before continuing.
- Re-level the frame after panels go down, since the added weight can shift it.
Skipping these steps leads to gaps between wall panels and a roof that doesn’t line up. A level, square floor frame makes the rest of the assembly straightforward; a skewed one makes every subsequent panel fight you.
Set the frame on compacted gravel or concrete pavers so it doesn’t sit directly in damp soil. That extra hour of prep protects both the frame and whatever you store inside.
FAQs
What flooring material works best under a metal shed?
Pressure-treated plywood is the most common choice because it resists moisture and rot where the deck meets the ground. Some owners upgrade to composite or treated lumber planks for longer service life, though that raises the cost. Avoid untreated wood — it will wick moisture and deteriorate within a few seasons.
Can I set a 10×8 Arrow shed directly on grass?
No. The shed needs a level, firm base because the floor frame requires solid support across its full footprint. Grass settles unevenly and traps moisture under the metal panels. Compacted gravel or concrete pavers give you the stable, drainable surface the instructions assume.
Does the floor kit include fasteners for the deck boards?
The kit ships with the frame components and hardware to assemble that frame, but the decking material and its fasteners are separate purchases. You’ll need screws rated for exterior use to attach the plywood or planks to the frame. Budget for both before starting assembly.
