Lux Spa & Fitness, San Francisco

Whatever spa treatment you're in the mood for—a facial, a hot-stone massage, a body wrap, a waxing, a mani-pedi—it's advisable to budget an entire afternoon for Balance Spa and Fitness. Since the spa offers complimentary access to its lavish amenities, the extra time can be spent simmering in the jacuzzi, taking a leisurely dip in the pristine indoor lap pool, or working up a sweat in the fitness center. When treatment time arrives, the staff leads its robe-clad clients to one of the four private treatment rooms. The specialists favor advanced Naturopathica products made from age-defying ingredients such as soothing aloe, refreshing lavender, and Helen Mirren's DNA.
