No words in a Restroom

B"H

Jews are not allowed to speak in a restroom. It happens many times that someone is busy in a restroom while a second person is looking for him. In this case, the first person knocks on the inside door of the restroom so that the second person is able to hear him and thus knows where he is.

Furthermore, the Talmud teaches us that no one should use the word SHALOM in a restroom, as SHALOM is one of G - d's names.
