Bests & Worsts Reviews from Amazon

This is hardly a "large" litter box; do better than I did, and pay attention to the actual measurements (18.5 x 15 x 8.3 inches) ... and realise that the largest of the three, is the HEIGHT from the floor, including the white rim. That's right, the actual size of the pan is only 15 inches by eight-and-a-third. I was expecting eighteen-by-fifteen, with an eight-inch depth. Joke's on me, it seems. Bah.
