Les Bains Paris occupies a storied address in the Marais, where a nineteenth-century bathhouse later became one of the city’s best-known nightclubs before its transformation into a hotel. Tristan Auer designed the 39 rooms and suites with polished wood, velvet, white marble and bespoke furniture, balancing the building’s nightlife history with a more residential mood upstairs. Roxo anchors the dining programme, while the bar and revived nightclub retain the property’s social character after dark. The original bathhouse legacy reappears below ground through the swimming pool and hammam, giving the hotel an unusually direct connection between its past and present.
