Obviously the world’s largest bathtub isn’t meant for a single person or small dens. Sized at 25 feet (height) x 12 feet (width) x 72 feet (length), this colossal bathtub is backed by Guinness World Record (UK) for being the world’s largest. Estimated at $118,000, this bathtub has room for lots more than just a shower. It is befitted with steam rooms, perfumed sauna boxes, LCD screens, telephone service, Jacuzzi pool, high-tech shower panels along with a large water pool and a four feet deep tub. But environmentalists will frown at the fact that it needs about 24,000 liters of water to be at your service. Currently this mobile Bathtub is on display in Mumbai, India. With this much space and so many splish-splash options, it is ideal to throw a bathtub party as pool parties are passé.
