Is it normal to only shower in the morning?
Yep.Totally normal
Yes, it’s completely normal to shower only in the morning. When you shower is mostly a matter of preference, as long as you’re keeping clean in a way that works for you.
Lots of people shower in the morning because it helps them wake up or fit neatly into their routine. Other people prefer evenings, and some shower at different times depending on exercise, weather, or how sweaty they get.
You don’t need to shower twice a day just because someone else does. If you feel clean and comfortable, a morning-only shower is fine.
