My only concern is that because we've built an open shower steam can

If you do, you're throwing heated air out, like pointing a small fan
heater outside. A crossflow exchanger would mean you retain the
majority of the heat while still changing the wet air for dry.

I didn't know such a beast existed....ta! I'll have a google around.
