The Giant Bath Tub for Tsar Alexander I in Babolovsky Palace, St. Petersburg, Russia.
In 1818, a chunk of granite weighing more than 160 metric tons was delivered to Babolovo village from one of the Finnish islands. The only thing that craftsmen had to do was to cut off all of the excess rock. The work took 10 years to finish and this unusual project resulted in a polished granite bath 196 cm (6.5 ft) high, 152 cm (5 ft) deep, and 533 cm (17 ft) in diameter with a mass of 48 metric tons. The volume data indicates that 8000 buckets of water could fit inside it.
