Northern extent of wall was cut for the construction of Su 5842 and wall 5789. This cutting removed its northern extent and a drain was constructed beneath wall 5615 between rooms 21 and 13.

W wall of room 13. At least three points to underline: the presence in this room of signinum floor laying on suspensurae in phase with the wall, the physical connection with a small basin (5817) paved in signinum (5818), and the proximity to room 7 (N side), whose function of latrina are even more plausible after a first cleaning. Due to these elements, it seems quite reasonable to connect this room with bath functions.
