I would like to see the ash pan a little deeper. However I don't see the need for a second ash pan. I carry mine out to the garage and dump it in a large wash pan. Then I bring the ash pan back in and slide it back in the stove. The open end of the pan is nice because it scoops up any ash that lays in the bottom. With my wood stove I had to shovel spilled ash out of the stove bottom and put it in the pan. One advantage of the pan not being too big is that I can carry it with one hand and use the other hand to close the ash door and open the house and garage door as I carry out.
One person and one pan are all that is needed. Works well. I empty every day to day and a half.
