I think not.
We've been bathing in private for the past 200 or so years hereabouts. It is difficult, if not improbable, to reverse such a trend in society and culture so quickly.
While I may actually feel this is a thing that society might benefit from; I don't see this happening outside of nations with a lower societal taboo, and more robust cultural norms and practices on the subject of nudity. It works in Japan simply because that's how their entire society has been structured from the start, and their society largely agreed that communal bathhouses made much more sense logistically and economically; largely due to the fact that it is an island nation, and land space is more precious there.
Furthermore; I personally also prefer privacy. As a trans individual; that privacy is strongly necessary to me for many valid reasons concerning my own safety and health; and for ensuring others do not feel unsafe; regardless of their reasons for feeling that way.
Society is not ready for this kind of thing anymore and has mostly chosen to abandon the practice to antiquity.
