Does an Arrow Resin Series shed come with a floor?

Yes. Every Resin Series shed ships with its floor included — the box holds the panels, the frame, the floor, the roof, the hardware and the instructions. The walk-in sizes have a reinforced floor and the vertical sheds a built-in floor. That is the difference from Arrow's steel Classic and Select sheds, which take a separate floor frame kit. Set the shed on level, well-drained ground all the same: a gravel pad, patio slabs or a concrete pad keep the floor flat and the doors in line, and anchoring is worth doing on an exposed site.
