Will BISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 " fit in a Renault Kangoo 2023?

The Kangoo's cargo area is a small van's load bay wearing a passenger badge. The mouth is 47¼″ wide × 43¾″ tall, the floor runs 40⅛″ with the bench up and 69¼″ folded (a +29⅛″ gain), and the width holds 46⅞″ clear between the wheel arches. The floor meets the sill at 22⅞″ with a 0″ drop, so a heavy box slides straight in with no lift-and-lower step. Tall boxes, wide boxes, stacked multi-box orders: this space takes them all without complaint. The one thing that beats it is sheer length, boxes well past the folded floor. Load flat and push; that flush sill is the best feature here.

BISSA ships as a single flat box, 54¼″ × 16¾″ × 3″, and it weighs 45 lb 15 oz. At 3″ thick it slides into gaps a built cabinet never would, so the thickness is not your problem. The length is. At 54¼″ you need a trunk that measures long enough on the floor, or one rear seat folded so the box can run forward between the seats. Most hatchbacks take it with the seats down, and any wagon or SUV swallows it flat. Lift it on edge with two hands, and rest it on a long edge rather than a corner, because 45 lb 15 oz of flat pack lands hard and the corners split first.
