Wait?

Wouldn't that mean that you bathe in 20L of water? I know it's only the eyeball test, but most of the bath tubs I've seen seem to be filled with more than 20L when in use. Particularly if people are soaking, which would be a fair comparison to a long shower.

I think maybe we need some kind of way to recycle water for more than one night, and reheat it efficiently. Then baths start being better for the environment.

I have no idea how to do that? (Or even if you can do that?) But it seems a good way forward if some company made tubs like that.

Sorry if I wasn't clear, I meant that most people I know seem to shower for >>2 minutes, so I doubted the credibility of the comparison.

Clearly, if you are fairly consistently sticking to 2-minutes showers, that's going to be more economical than baths -- even with some degree of sharing.
