Hadith.239 - Imam Jafar ibn Muhammad Al-Sadiq عليه السلام said:
'The bathhouse is an undesirable place; it removes coverings (privacy) and exposes the private parts. However, it is a good place as it reminds one of the heats of the Fire (Hellfire).'.
Among the etiquettes: a man should not enter the bathhouse with his child if it would lead to the child seeing his private parts.
