Made with 18-carat gold, the tub took eight months to build, according to Kyodo News.

With a diameter of 130 centimeters (51.18 inches) and depth of 55 centimeters (21.65 inches), it can accommodate up to two adults.

The tub is located at the newly reopened natural hot springs complex at the Dutch-themed park, which happens to be a popular destination among Chinese and South Korean tourists, according to the South China Morning Post.
The resort, which features various-themed baths, is known for its salty, brown-colored spring water.

The tub, marketed as a provider of good luck, is currently valued at 800 million yen ($7.15 million).
Guests can book one of ten hour-long sessions available in the private bath for 5,400 yen ($48) an hour.

“This gold bathtub outclasses all others in the world, and we hope our customers enjoy it and increase their luck,” Huis Ten Bosch said on Monday.
While Guinness has recognized the tub, it will only bestow the certificate after confirming that it does not leak.
