Priced at a staggering US$50,000, the latest experience by US bath bomb company ME! Bath is the most expensive bath ever created.

Called the Eighth Continent, the ingredients for the experience - which can be custom-ordered for any spa or house in the US or the UK - are some of the rarest in the world.

The water, for example, is said to come from ancient glaciers in the polar ice caps, mixed with Hawaiian deep sea water sourced from 914m below the ocean surface.

Other ingredients include sidr honey from the Arabian peninsula, Peruvian pink salt crystallised in natural springs, creamy kokum butter from India, Israeli organic jojoba oil and - of course - 24 carat gold.

To top it off, it's delivered in a silver case hand-crafted in Israel. ME! Bath says a large portion of proceeds from each sale goes to charity.
