The large mirror perfectly matches the 12th-century stone vault. Just behind the mirror, a swimming pool lets you swim against the current. The white mosaic echoes the vaulted ceiling, and the indirect lighting is subtly scattered throughout. And let's not forget Paris in the light, always present through tiles printed in panoramic format of the Alexandre III bridge. The water is at the perfect temperature, and the bubbling jets gently massage you... the promise of a moment of pure bliss.
