What is the ruling on a husband and wife bathing together in the bathroom, with the possibility of engaging in sexual intercourse therein, and what is the ruling on one who has sexual intercourse with his wife in the bathroom?

There is no harm for a husband and wife to bathe together in the bathroom, as it is authentically reported that 'A'ishah, may Allah be pleased with her, and the Prophet, peace and blessings be upon him, used to bathe from a single vessel. There is no harm in a husband having intercourse with his wife in the bathroom, but this goes against proper etiquette, and it becomes difficult to recite the prescribed supplication for intercourse due to the impurity of the place.
