Question:
Is it permitted for men to shower during the nine days after relations instead of mikvah?
Answer:
Hello,
A man that is always makpid to go to the mikva after relations may do so after relations during the nine days. If he isn’t makpid on this all the time, then he can’t, similar to going to the mikva on erev Shabbos. If he can’t go to the mikva he can do 9 kavim in the shower. However it has to be done with cool water, (whatever he can handle) similar to the mikva, and it is without soap, shampoo etc. For more guidance regarding 9 kavin see the following links https://dinonline.org/2016/09/18/bath-for-9-kavim/ and https://dinonline.org/2016/09/18/bath-for-9-kavim/
Best wishes
