Bath guy, sorry.

Morning.

On my birthday, whether I need it or not.

Usually within about half an hour after waking up. I take another shower early evening as well but much shorter. If it's summer and very hot, there may be a third shower sometime in between.

When does it ever get hot in Canada? Wouldn't your igloos melt?

Any time that feels right.

Morning.

Morning, but also as needed if it is a sweaty day!

When you're use to -40 in the winter, those -10 summer days are sweltering.

Evening. Lets me sleep for an extra half-hour. (I'm not a morning person.)

If it matters, I tend to take my bath in the evenings.
I find them reflexing, especially after hard days.
They help me go to sleep, and I like to go to bed clean.

I tend to find that showers revive me if I feel sleepy.

Thursdays

Usually Saturday Mornings - I shower off, then take a bath, shave in the tub, then shower again.

And during the week, whenever I get done doing something filthy, like yard work, plumbing, etc. and/or broke a decent sweat, a quick shower usually does it - or a longer bath with a beer and a couple of Excedrin if my muscles ache.

And probably before any appointment, like a doctor or dentist, etc. If I'm planning on being close to somebody, I'd rather not smell bad.

Every morning within 30 minutes of getting up.
In the hot summer, I will take refreshers.
