Q. When exiting a regular W.C. (beis hakkiseh) there is no need to wash hands three times. However, when you exit a bathroom where one takes a bath you should wash hands three times. On Yom Kippur when you have to be careful not to wash unnecessarily, if one exits one of our common home bathrooms that contain also a bathtub and shower, do you have to wash three times, or maybe that applies only to a public bathroom like a mikva?

A. Horav Shlomo Miller´s Shlit´a opinion is that due to the existence of various different traditions and opinions in regards to when to wash hands after exiting the different types of available facilities, or if to wash with a keli and how many times you wash, one may on Yom Kippur maintain the minhag of how he usually washes the rest of the year. He recommends to wash only once. However, one must be careful to wash only up to “kishrei etzboisov” or the upper knuckles.
