Luxury and convenience are primary bath design goals. These are intimate spaces where, as in the bedroom, our focus is caring for ourselves. Spas are often an influence as they translate into soaking tubs and, if there’s room, separate showers. Kitchens and baths respond eagerly to technology, so, in addition to fine traditional elements you can pick from a dazzling array of innovative materials and new marvels of function. As for powder rooms, if you wish, they can be the equivalent of jewelry: concentrations of color and style for a dramatic impact.
