We added shelves to our middle cupboard in the pantry. And also the little cabinet at the end of the island. In the W/D closet, ours came with 2 wire shelves and a hanger rod. I attached wire baskets to these two shelves so things don't fall off when traveling. I found one large wire basket at Lowes that just fit the shelf. It is about 6 inches deep so holds all the laundry supplies, iron, etc.
Here are pictures of shelves we added. We angled them a little so stuff would not slide forward.
