Sauna entities are more Stream transducers rather than actors - they do not have a state, their communications is inherently unidirectional, they're pretty high-level. Therefore I think it would be reasonable to start to rewrite them in akka-streams.
Current plan
Implement few more responders/observer to get broader picture
Swap Play WS with akka-http as it has streams as basis
