The Naga are carved into the stone surrounding the bath before rising up in the center. They are there to protect it. The detail shown on them along with the bath itself is some of the best proportional work in Nepal.
If you walk down into the bath take a close look at the well crafted stone water spout which was added in 1688. It used to be fully gilded but time has taken its toll here.
Above the spout are small replicas of original statues of various deities that have been stolen over the years.
From Bhaktapur Durbar Square locate the Golden Gate along the main old Royal Palace wall. Pass through it into the inner Royal courtyards to the Taleju temple. Simply enter the compound to the Royal bath from the small gate to upper left-hand side of the Taleju Temple entrance if it is directly behind you.
