Water Tub
An Water Tub is a usually seen in stables or dungeons. It serves no real use other than decoration, with the exception that if emptied it will turn into an Empty Tub which can be picked up and used as a Container.
By draining the water tub with an Empty Pitcher, the tub will become an empty tub and can be picked up. Water tubs can be found in the stables just west of Britain, among other locations.
While not commonly seen, many players falsely assume that empty tubs are Rares, even to the extent that some unscrupulous players offer them for sales as such.
