Oddee has pictures of twelve unique bathtubs, such as the one pictured above, which was made out of 18-karat gold. Its estimated value was $1 million, which is probably why it was stolen out of a Japanese hotel in 2007.
Other bathtubs at the link include one that looks like a high-heeled shoe and one inspired by the works of Le Corbusier.
