Which floor kit fits my shed?
Floor kits in this category are brand and size specific, mostly built for Arrow storage sheds. Match your shed's model line and footprint to the kit's stated fit before ordering; a kit sized for one Arrow line generally will not bolt onto another line's frame without modification.
| Kit | Fits | Price |
|---|---|---|
| Arrow Elite Floor Frame Kit | Arrow Elite, 4 ft deep sheds | $57.92 |
| Arrow Classic/Select Floor Frame Kit | Arrow Classic and Select, large sheds | $76.99 |
| Arrow General Floor Frame Kit | General Arrow shed and storage buildings | $110.58 |
| 10x12/10x14 Floor Frame Kit | Arrow sheds at 10x12 and 10x14 ft | $139.99 |
| 12x12/12x14/14x12 Floor Frame Kit | Arrow sheds at those three sizes | $169.99 |
| 12x16/14x14/14x16 Floor Frame Kit | Arrow's largest sheds at those three sizes | $199.99 |
Why does a shed need a floor frame at all?
A floor frame lifts a shed's floor panel a few inches off the ground, keeping wood or resin floor material away from standing water and letting air circulate underneath to reduce rot and rust. Without one, a shed floor sitting directly on gravel or dirt tends to wick moisture and wear faster, especially in wet climates.
Floor kit vs. foundation kit: what's the difference?
A foundation kit, like a gravel grid or paver system, prepares the ground the shed sits on. A floor kit is the framing that sits on top of that ground prep and holds the shed's actual floor panels. Most sheds need both: foundation prep underneath, floor frame on top. See our foundation kit picks for the ground-level half of the job.
What if my shed isn't an Arrow?
Every dedicated floor kit in this category is built for Arrow sheds specifically. If you own a different brand, check with that manufacturer for its own floor kit first; a mismatched frame risks gaps or a floor that doesn't sit flush with the shed's wall panels. Some owners build a simple pressure-treated frame instead, sized to their shed's exact footprint.
How we chose these
Nothing here was assembled or tested in person. These picks are researched from manufacturer fit specifications and recurring themes in verified owner reviews, checked line by line against each kit's stated shed compatibility so a "fits your shed" claim is never assumed, only stated when the listing says so.
Buying tips before you order
- Confirm your exact Arrow model line and footprint against the kit's stated fit before ordering; Arrow product lines are not interchangeable.
- Order a foundation kit or gravel pad to go underneath if you don't already have level ground prepared.
- Lift and assemble frame rails with two people; individual rails are long and awkward even when light.
- Check your local code before any permitted structure work, even floor-level additions to an existing shed.

Will an Arrow floor kit fit a different brand's shed?
Not reliably. These kits are engineered to Arrow's own frame dimensions and joist spacing for specific product lines. A different brand's wall panels and floor opening likely won't line up, so check with your shed's manufacturer for its own floor kit, or build a custom pressure-treated frame sized to your exact footprint instead.
Do I need a floor kit if my shed already includes a floor?
Many sheds ship with a floor panel but no elevating frame underneath it, meaning the panel sits close to or directly on the ground prep. A floor kit adds the joist structure that lifts the panel a few inches up, improving drainage and airflow. Check your shed's included parts list to see whether a frame is already part of the package.
Can I use a floor kit without a gravel or foundation base?
It's not recommended. A floor kit still needs a level, stable surface to rest on; without a gravel pad or paver base underneath, the frame can settle unevenly over time. Pair a floor kit with a foundation kit or a properly built gravel pad for the best long-term result.
How do I know which size floor kit I need?
Match your shed's exact model line and footprint, in feet, against the kit's stated fit. Manufacturers list compatible sizes directly in the product title and description, as shown in the comparison table above; guessing based on footprint alone can miss line-specific frame differences.
Is a bigger floor kit always better?
No. A floor kit sized larger than your shed won't fit the wall panels correctly and wastes money on unnecessary material. Match the kit to your shed's actual footprint rather than buying up; the largest kit here is only the right choice for the largest Arrow sheds it's built for.
