שולחן ערוך אורח חיים · סימן קס״ה

English

One who defecates and subsequently wants to eat should wash his hands twice, and say Asher Yatzar on the first washing and Al Netilat Yadayim on the second washing. And if one only wants to wash his hands once, after he washes he should say the blessing of Asher Yatzar, and afterward at the time he dries [his hands] he should say the blessing of Al Netilat Yadayim.

English

If many people are at a meal, the most important one should wash first. And the Rosh was careful to wash last in order that he should not have a pause, and he should not speak [between washing and eating bread].
