The Ruling on Mixed Bathing Establishments and Entering Them

Question:
Indeed, some of the women’s bathing places are entirely for women, where women gather and attend.

Answer:
Regarding bathing establishments intended for bathing and washing, which are not the bathrooms we know today that are places for relieving oneself, but rather the known baths used only for washing, which have perfumed hot water and a specific system: if there are separate baths for women, there is nothing wrong with it. However, if they mix with men in one bath, this is not permissible because of the exposure and uncovering of the awrah (parts of the body that must be covered) and the free mixing of men and women. This is not permissible. It is also not permissible for a person to enter a mixed bath and say, "I am just washing and cleaning." No, a mixed bath is an abomination (munkar) and he is not allowed to enter it. Yes.
