Will BISSA Shoe cabinet with 3 compartments, white, 19 1/4x11x53 1/8 " fit in a Skoda Octavia Combi 2025?

A wagon body means one thing here: length. The opening measures 40½″ wide by 30¾″ tall, the load floor runs 42⅞″ with the seats up, and folding the bench takes it to 73¼″, a gain of 30⅜″. Between the wheel arches you still get 39⅜″ of width, so long flat boxes lie flat on the floor instead of angling across it. The catch is the 30¾″ opening height: tall cartons go in on their side or not at all. The lip sits 25¼″ off the ground with a 3⅞″ step down to the floor, so slide heavy boxes across the sill instead of lifting them over it, and load the longest box first.

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.
