In every private tanning room at Sun Spot, a shelf and hangers ensconce clothes and satchels. Shoes flop to the floor next to comfortable seating, slipping from the feet of patrons adjusting the volume on personal AM/FM stereos-CD players before the UV bed coaxes out melanin. The UV beds range across six levels of tanning power and sport adjustable body fans so guests can stay cool or find an excuse to redesign the north wing of a house of cards. A parade of clients wanders from VersaSpa booths, which darken skin with a bronzing elixir infused with custom color and moisturizer designed to hide the effects of aging. Slipping out past swaying bamboo plants, visitors pass beneath infrared slimming machines and glass shelves that brim with a rainbow of sun-luring lotions from Norvell and Devoted Creations.
