It's funny how these MC's brain doesn't seem to work at all. He says 'yay, free bath privileges' while in reality, the owner is just going to make him clean the entire bathhouse for free every day, and in exchange, he can take a bath? That's it? How is that equivalent exchange at all? Dumb idiot. Also, with that kind of OP magic and such an open world, he doesn't specifically need to go to a bathhouse (which doesn't seem to have any decent facilities either).
