Can you were a Tzitzit katan in the bathroom, can you wear it at all times, and can you tell me something it says in the Talmud? Thanks.
It is permitted to enter the bathroom with a tallis katan, and it can be worn at all times. Although there is no explicit source for this in the Talmud, and the Taz (21:3) is stringent when the strings are revealed, it is not customary to be stringent concerning this matter (Peri Megadim).
Moreover, the Talmud mentions that one must take off one’s tefillin before entering the bathroom (Berachos Chap. 3), but makes not such stipulation concerning tztitzis, thereby implying that there is no obligation to take off one’s tzitzis before entering the bathroom.
