Epstein's temple was likely inspired after a Mamluk Public Bath
Looking at the architecture it has extremely close characteristics of Hammam Yalbugha in Syria. Either directly inspired by Yalbugha or just (Mamluk)public bath houses in general, people can't deny the similarities.
Hammam(Public Bath)
Epstein's temple also has other noticeable characteristics, such as the dome is similar to the Dome of the Rock mosque in Jerusalem. Which could give some type of religious significance.
The temple is also laced in bright blue and white stripes which could also resemble a traditional Turkish hammam towel.
Epstein's original design for the temple was actually more of an octagon (plans for 3,500 sq. ft building), which would be a perfect style to host a public bath pool, but this never surfaced as far as we can tell. It's quite possible that the octagon shaped room(that would be ideal for building a hammam) is underground. Something of this nature could be built to host dozens of naked girls in a public bath environment. Epstein's predatory process also revolved around massages going sexual which is something that can easily tie into public baths.
