Activities That Require Netilat Yadayim

Netilat Yadayim is a ritual washing of one's hands. It is requires at certain points during the day including waking up, before a meal, and before davening. For those halachot, see the following pages: Netilat Yadayim upon Waking Up, Netilat Yadayim for a meal, Netilat Yadayim in preparation for Davening. For any other washing, see the details below.

After Leaving the Bathroom

1. The Shulchan Aruch (4:18) quotes from several rishonim that there is an obligation for one to wash netilas yadayim upon leaving a bathroom even if one did not relieve themselves. Many poskim hold no kli is necessary and neither is 3 times.
2. The Gemara (Brachos 26a) describes a beis hakisei diParsai, which was a particularly clean bathroom because the waste would roll down to a pit a distance from the actual toilet, and therefore did not have some of the dinim of regular bathrooms. Modern poskim query whether our bathrooms should be treated like a beis hakisei diParai, and thus one would not require netilas yadayim upon exiting them, or not. The Chazon Ish (17:4) leaves this question in doubt, since unlike the bathrooms of the Parsai, in which the waste was removed immediately, our toilets hold the waste for a period of time until it is flushed away. Rav Shlomo Zalman Auerbach (Halichos Shlomo Tefilla 20:24), however, is lenient about this, and the Minchas Yitzchok (teshuva 1:60) concludes that in cases of need (bishas hadchak) one may be lenient not to wash upon leaving our bathrooms.
