Question:
Greetings,
Surely one should make an Asher Yatzar immediatly after using the bathroom, but if he didn’t, up to how much time does he have to make the brocho? Thank you
Answer:
Thank you for your question.
A person can say asher yotzar until there is a feeling of needing to use the bathroom again. After that time, the benefit of using the bathroom the first time has already dissipated.
Best wishes
