May I take room temperature showers during these three weeks leading up to Tisha B'av? Thank you.
AskTheRabbi.org answered:
There is no problem with showering using hot water up to the beginning of the Nine Days (the Nine Days begin on the first day of the month of Av — Rosh Chodesh Av). After the Nine Days you should endeavor not to use water that is more than lukewarm.
