Bathing as a teenager, I wasn’t overly concerned about cleanliness or speed. I was more worried about hot water and laying down for a bit longer in the morning.

Now, as an adult, I haven’t had a bath in several years. I’ve thought about it; standing, for me, is hard because I’m obese and have an old ankle injury that was repaired incorrectly. However, ultimately, I always end up going for the shower - because, as you said, it’s more efficient - then trembling on the bed for ten minutes until my ankle recovers.

I agree, though. For effectiveness, go for a shower. For luxury, a bath might be appropriate.
