A luxurious bath complex is situated in the south-east corner of the edifice. The bath, which is composed of many rooms, was built on a plan characteristic of private thermal establishments intended for a limited number of users. Unlike the big Imperial baths, which usually had a one-way circuit for the bathers, here the users of the bath had to retrace their steps through the various parts of the establishment. A large frigidarium (cold room), decorated with a fine geometric mosaic, occupies the centre. Two big basins for cold ablutions were located on its north side: originally they were revetted with marble slabs and decorated with marble sculptures. On the east side of the cold room another basin for foot-washing was added at a later period. The heated part was placed on the south side. Hot air distributed from the nearby oven heated the hypocaust floors of the tepidarium (moderately heated room), sudatorium (steam bath), and caldarium (warm bath). The bath had two apodyteria (dressing rooms), a cella unctuaria for anointments, a latrine for 12—14 people at a time and an elevated water tank. All rooms were embellished with floor mosaics, murals and marble revetment for walls and basins. The bath was provided with a complicated system of drains and pipes. Used water from the cold basins was directed though channels to flush the latrine. During their long existence the baths underwent numerous alterations and in their final years became accessible also to people from outside the villa.
