I don't shower every day.
I shower every day I have to go into the office (Tue/Wed/Thur) an after I work out (usually Tue/Thur night and one day on the weekend usually in the afternoon). But I only rarely shower on Fri/Mon mornings when I don't have to go in. I also shower on any days where I do yard work or anything that makes me sweaty/grimey/feel dirty
I used to shower 7 days a week, and frequently showered multiple times on those 7 days, on average I probably showered ~12 times a week. Biggest changes ... I had kids and remote/hybrid work. I'm default parent usually, and I just don't have time to shower every day anymore on the weekends, unless it's at 12PM when my wife gets up or something, but at that point I've already been up for 6 hours and I'm dressed. If we're going out with friends or something then I'll take a quick shower and dress properly, but if I'm with 5 year old kids all day, then I don't care.
