The Bracha on After using the Bathroom is Asher Yatzar.
Blessed are You, Lord our God, King of the universe, Who fashioned man with wisdom, and created within him many openings and many cavities. It is obvious and known before Your throne of glory, that if but one of them were to be ruptured, or but one of them were to be blocked, it would be impossible to survive and to stand before You. Blessed are You, God, Who heals all flesh and acts wondrously.
Baruch Atah Adonai, Eloheinu Melech Ha’olam, Asher Yatzar Es Ha’adam B’chachma, U’vara Voe N’kavim N’kavim Chalulim Chalulim. Galui V’yadu’ah Lifnei Chisei Ch’voe’decha, She’im Yipa’saye’ach Echad May’hem, Oe Yisa’same Echad May’hem, Ee Efshar L’his’kayaim V’la’amode L’fanecha. Baruch Atah Adonai, Rofay Chol Basar U’mafli La’asos.
