Bathhouse Etiquette

[Heartnet24]

Hello! I'm not sure if this is the right forum to be asking about this, i also couldn't find a thread relating to this (but maybe I missed it). But I appreciate anyone's feedback.

I'll be going on a vacation next month, and I want to visit the local bathhouse, but I have never been to one before. I was wondering what the etiquette is for wandering around the bathhouse, and if I should do anything leading up to going (besides getting myself ready)?
