Q. Rov, I heard about a very interesting ruling of the Mishna Berura that on can enter a bathroom without taking off his kitel (white robe used by men during Yom Kippur). Could that be correct?
A. Indeed, Mishna Berura (610: 18) rules that one may enter a bathroom just to urinate while wearing his kitel.
However, Horav Shlomo Miller’s Shlit’a opinion is that although bathrooms are cleaner in our days than the way they were in the days of the Mishna Berura, yet they are used now for the relief of both bodily needs and therefore one should remove his kitel before entering the facilities.
That seems to be the common custom in our times.
