The Scholastikia-Bath, also called Varius-Bath, was a public thermal spa. They were built at the end of the 1st and beginning of the 2nd century AD together with the public latrine and brothel. The spa, built by Publius Quintilius Valens Varius and originally named after him, is located on the Kuretenstreet, one of the most important boulevards of Ephesus, separated only by the temple of Hadrian.

Of the once three-storey building, one of the largest in Ephesus, only remains of the ground floor have survived. Access was through the main entrance on Kuretenstreet; to the east, a staircase led to Bathalley and the side entrance there. Both paths led to the Apodyterium, an L-shaped hall with ten niches and an apse, from which one could presumably look out onto the Kuretenstreet.
Inside this room there were numerous statues. Today, the headless statue of Scholastikia, a rich Christian citizen of Ephesus, who donated part of her fortune to the renovation of the thermal baths in the 4th century, can only be found in a niche to the left of the side entrance.
From the changing room one reached the public toilet via the originally covered Akademiealley. In the middle there was a square basin, at each of the four corners of which a column stood. The toilets themselves, under which a canal with running water disposed of the faeces, were covered. In front of the bench there was a circumferential channel in the floor with clear water that could be used for cleaning.
To the west of the Apodyterium lay the Frigidarium with its elliptical cold basin, and on the north side the Tepidarium for warming up. The clay tubes, which were installed in the ground and in the walls, provided the necessary hot air circulation.

In one corner of the room a small part of the original coloured marble flooring has been preserved, the rest of the flooring dates from around 400. A narrow door leads from the tepidarium to the caldarium. Here the walls are still preserved in their original height, but the wall panelling dates from different eras. Under the floor of this room was the boiler room, which supplied the whole installation with warm water and hot air. The associated hypocaust is well preserved.
