"Na'im the freed slave of Umm Salamah narrated to me that Umm Salamah was asked: 'Can a woman perform Ghusl with a man?' She said: 'Yes, if she is well-mannered.[1] I remember the Messenger of Allah ﷺ and I performing Ghusl from a single wash tub. We would pour water on our hands until they were clean then pour water over them.'" Al-A'raj said: "Not mentioning the private area not paying attention to it." [1] Kaiysah:" Well-mannered when using the water with the man" (An-Nihayah) And the comments by Al-A'raj after the narration refer to its meaning.  

حَدَّثَنِي نَاعِمٌ مَوْلَى أُمِّ سَلَمَةَ ؓ أَنَّ أُمَّ سَلَمَةَ سُئِلَتْ أَتَغْتَسِلُ الْمَرْأَةُ مَعَ الرَّجُلِ قَالَتْ نَعَمْ إِذَا كَانَتْ كَيِّسَةً رَأَيْتُنِي وَرَسُولَ اللَّهِ ﷺ نَغْتَسِلُ مِنْ مِرْكَنٍ وَاحِدٍ نُفِيضُ عَلَى أَيْدِينَا حَتَّى نُنْقِيَهُمَا ثُمَّ نُفِيضَ عَلَيْهَا الْمَاءَ قَالَ الأَعْرَجُ لاَ تَذْكُرُ فَرْجًا وَلاَ تَبَالَهُ  

[Machine] Yes, "If it was a small container, you would see me and the Messenger of Allah ﷺ washing ourselves from a single vessel, pouring water onto our hands to cleanse them, and then pouring water onto ourselves." Al-A'raj said: "You don't mention the private parts and you don't care about them."  

نَعَمْ «إِذَا كَانَتْ كَيِّسَةً رَأَيْتُنِي وَرَسُولُ اللهِ ﷺ نَغْتَسِلُ مِنْ مِرْكَنٍ وَاحِدٍ نُفِيضُ عَلَى أَيْدِينَا حَتَّى نُنَقِّيهَا ثُمَّ نُفِيضُ عَلَيْنَا الْمَاءَ» قَالَ الْأَعْرَجُ لَا تَذْكُرُ فَرْجًا وَلَا تُبَالِيهِ
