This is not fictional, Japan has come out with a valuable crystal lavatory studded with more than 72,000 pieces of Swarovski.

The Japanese always believed that a deity rules the lavatories and followed the truism ‘cleanliness is next to Godliness’. No wonder, the Japanese always keep their lavatories exceptionally clean.
This crystal lavatory was perhaps created to propitiate the "God of Lavatories."
