Le Meurice, Paris
All the bathrooms at this palatial Louis XVI-style hotel are distinctive, featuring the same rare Pyrenean red and ochre marble that was used in the Château de Versailles. Still, it’s the 270-square-foot washroom in the top-floor Belle Etoile Royal Suite that really stands out. There's a round Jacuzzi tub in its own alcove, toiletries from luxury British brand Penhaligon (and special Le Petit Prince products for children), and a spectacular 360-degree view of Paris—enough to encourage guests to linger much longer than intended. Not to be outdone, the hotel’s sixth-floor Marco Polo Suite also has its own unique appeal, with a triangular shaped ceiling inspired by a tent from the Napoleonic period. Here, beyond an entrance framed by soft blue draperies, you'll find an antique-style bathtub and stone marquetry floor made from Portuguese rose marble and boxwood.
