Minecraft wiki entry for Making_nice_floors, associated text: For a storage room, a lot of the floor design is up to you, similar to a bedroom. If you have an above-ground storage room and you want it to look nice, try using wood, wood planks, or stone bricks. If your storage room is in the basement, and you want the floor to not look quite as nice for a realistic basement look, use cobblestone, or for an even more worn down look, the eroding floor design, with andesite and diorite. Additionally, many players make their storage room part of their bedroom.
