The size of Banyuniba Temple is relatively small, which is 11 m wide and about 15 m long. The body of the temple stands on a 2.5 m high 'batur' located in the middle of a neatly arranged andesite stone. The difference in the area of ??the batur and the body of the temple forms a corridor wide enough for 1 person to pass through. The walls and upper seams of the batur are filled with ornaments with tendril and leaf motifs that extend out from a container similar to a jar. At each corner of the foot of the temple there is a decoration resembling a Kala head called 'jala dwara". This decoration functions as a drainage channel for rainwater. The roof of the temple is a pyramid-like dome (dagoba) with a stupa at the top.

To climb to the hall on the surface of the 'batur' (the foot of the temple) there is a staircase about 1.2 m wide, located right in front of the entrance to the viewing room. The base of the ladder is decorated with the heads of a pair of dragons with wide gaping mouths.

The entrance is equipped with a 'viewing' booth with a curved roof that protrudes around 1 m outside the body of the temple. The front side of the roof of the viewing room is decorated with tendrils. Right above the doorway, there is a Kalamakara decoration without the lower jaw. On the inside of the wall, above the doorway, there is a sculpture depicting Hariti, the goddess of children, sitting cross-legged.

On the south wall of the viewing room there is a relief depicting Kuwera, the god of wealth, sitting with her right hand resting on her thigh. On the left, slightly to the back, a servant holds a bag of money.

On the walls on all four sides of the temple body there are fake windows, namely holes that look like windows, but in fact the holes do not penetrate into the interior of the temple body. Above the false window sill there is a Kalamakara decoration, while on the left and right there are niches containing carvings of figures of the inhabitants of heaven or paradise, such as kinara and kinari, hapsara and hapsari, and Hariti and Avataka. Between the kalamakara and the upper pleats of the window sill is hidden a carving of a man sitting as if looking down. This kind of decoration is called 'kudu'.

There are no statues in the interior of the temple body, but the walls are decorated with figures of children and men in various positions. There are carvings depicting a child hanging from a tree branch, a row of people sitting hugging, a man sitting cross-legged, and so on.

In the courtyard of the temple there is a pair of statues of cows in a sitting position. There is no information whether the statues are actually located in their original place or have been moved from their original place.
