The most expensive bathtub is £530,000 ($845,000) which was cut from a 10 ton (20,000 lbs) Amazonian crystal stone and is on sale at Harrods store in London, UK. It is 2 m (6 ft 6 in) long and weighs more than 2 ton (4,000 lbs) when full.
The bath was designed by Luca Bojola for Italian interiors company Baldi. The bath is sculpted with diamond cuts and left partially rough to expose the natural beauty of the crystal.
