New technologies are developed everyday. Especially in 3D printing techniques. One of the latest developments is the printing in stone. Layer by layer the sand becomes a solid.

Due to the fact that with 3D printing there are a lot more possibilities, a single piece can have a lot of properties. Ad only the door and the pipe and you are ready to go.
