I used to just plug the drain when I took the shower and then let the water go down once it was close to room temperature. It added extra heat to the house, no question, but it added more moisture to the house than I was comfortable with(infiltration/exfiltration dew point concerns) so I stopped doing it outside of when the house was dry enough to consider it. I also didn't like cleaning all the soap scum out and now I've got my showers so short to where there's very little going to waste anyway.
