The ruling on speaking in the washroom حكم الكلام في الخلاء

Praise be to Allah, and may Allah’s peace and blessings be upon the Messenger of Allah, his family and his companions.

As to what follows:

In response to your question, we say, and with Allah Almighty lies all success:

Yes, a group of scholars based their dislike of speaking in the washroom on a hadith narrated by Dahhak bin `Uthman, from Nafi`, from Ibn `Umar, “A man passing by the Messenger of Allah (peace be upon him) while he was urinating, greeted him and he did not reply.” [Muslim (370)] 

The majority of scholars are of this opinion, while a group of scholars are of the opinion that speaking is permissible.

And Allah knows best.

Your brother,
