This is one of the four bathrooms in the penthouse, which is located in Guadalajara, Mexico. 15-storey building was built in the 1970s. The initial plan envisaged the construction of a second elevator. But he has not been established, although itself an elevator shaft built. The penthouse on the top floor and one of the bathrooms is located just above the elevator shaft. Designer Hernandez Silva found it a glass floor through which the shaft is visible, passing through all 15 floors. This must be the most frightening bathroom in the world.
