One Sauna is a gay sauna and hammam in central Montpellier, a short walk from Place de la Comédie and the Saint-Roch station. It describes itself as one hundred per cent gay and runs over three levels.
The centrepiece is a double hammam of around fifty square metres. There is also a dry sauna, a video room, a labyrinth, glory holes and a sling. A small shop inside sells lubricant and poppers.
