Trone is a French company that has set itself the goal of reinventing the bathroom experience. While Printemps Haussmann wanted to offer a new dynamic to its sanitary spaces, it solicited the sign to give it carte blanche. And the result should seduce fans of unusual photos and other Instagrammers, with a first cabin that is an immersive chessboard with black and white tiles. There are also chess pieces playing on optical illusions. The second one has colored neon lights for a real trip in a futuristic time and the third one has a total pink look and plays with lights, transparencies and reflections. A must see during a shopping session in Paris. More information on Trone's Facebook page.
