I hate this refrigerator. There is no space and the water dispenser does not accommodate anything but a regular glass. None of our water bottles fit under the dispenser so we have to fill a glass with ice, then water to fill our cups! There is no space inside and the bottom drawers in both of the refrigerator and freezer are only partial. I would be shocked if the inside is the 21’, I think it is impossible! I have only had it a few days and am just sick over the purchase! No space and poor design!
