Choose the size or layout
Use the widest outside footprint to plan paths. For a soil order, measure between the inside walls after assembly and choose your filled depth; advertised dimensions can be rounded. Rectangular sizes below read length × width × height.
Epic Gardening doesn’t publish inside measurements or an outside size for these beds, so the soil figure below is the maker’s own stated capacity. If you’ll fill it less deep, measure between the inside walls once it’s built.
| Size or layout | Advertised size | Listed capacity | Bags of 1.5 ft³ for that capacity | Plan |
|---|---|---|---|---|
| 38 in round, 15 in tall | 38 in diameter × 15 in tall | 9.85 ft³ | 7 bags | Plan this size: 38 in round, 15 in tall |
| 38 in round, 29 in tall | 38 in diameter × 29 in tall | 19.7 ft³ | 14 bags | Plan this size: 38 in round, 29 in tall |
Where the maker’s figures disagree
- The 29-inch page repeats 9.85 cu ft, the 15-inch figure; its own manual gives 19.7 cu ft.
- Both round pages say up to 20 sq ft of gardening space; a 38-inch circle is about 7.9 sq ft.
Measure the inside of the assembled bed before ordering soil.
What comes in the box
Parts

Before and while you build
- Wear gloves and closed-toed shoes to unpack and build it: Epic warns that the panel corners are sharp until the safety edge is on.
- Peel the protective film back to an inch past the bolt holes before you start, and take the rest off once the bed is built.
- Tighten every nut and bolt as far as it will go. Epic warns that a bed left loose could collapse.
- Epic says the finished size can vary by 2 inches either way: measure it before ordering soil.

Questions about this bed
Can it stand on concrete or a patio?
Yes, with a liner: on pavers, concrete, tiles or a porch, Epic Gardening says to lay a bed liner or geotextile fabric inside the bed and up its sides, which lets water drain but keeps the soil off the floor. To protect the surface more, it suggests thick builder’s plastic under the bed. Before you fill it on a patio or deck.
Can it be joined to another round bed?
No. Its panels are modular, Epic Gardening says, but a round bed can’t be combined with another to make a larger one.
Is it exactly 38 inches across?
Not always: Epic Gardening says the size can vary by 2 inches either way, from the way the beds are made. At 36 to 40 inches across, the 15-inch bed holds about 8.8 to 10.9 cubic feet, 6 to 8 bags instead of 7, and the 29-inch bed 17.7 to 21.8 cubic feet, 12 to 15 bags instead of 14. Measure across the inside once it’s built before you buy the last bags.

Prepare and assemble this bed
Compare the material, bottom and care choices if you are still deciding between families. Follow the site preparation and liner checklist for the supporting surface.
- Choose the exact configuration and lay out its parts. Check the required tools in the selected kit instructions.
- Prepare a stable, level position and confirm the outside footprint with working paths.
- Check corners, fasteners, protective edging and any layout-specific braces against the kit instructions before adding fill.
- Measure the finished inside and outside separately, then update your plan. Preserve the maker’s fill restrictions.
Mark the outside footprint on the ground before assembly, including any legs or protruding corners. Leave a route for carrying bags, reaching the plants and maintaining nearby beds.
This bed stands on the ground; its maker does not say whether it has a bottom, so look at the parts before you fill it. Check the soil and drainage where it will sit before adding fill. Its wall height is not a prescription for how deep the growing mix should be.
