Answered by Shaykh Faraz Rabbani
Are women allowed to have a shower, standing up. As I have heard many people say that a women should sit down and have a bath.
It is permitted to shower standing up, and there is nothing wrong with it.
However, if one showers sitting down out of modesty, or to follow the general way the Prophet (Allah bless him & give him peace) used to shower, there is reward in it, as the scholars have mentioned.
