Outside this new downtown luxury high-rise hotel, the equatorial heat rarely abates. But inside Remède's first Asian spa, seven low-lit treatment rooms have been designed to suggest cool grottoes, albeit ones stocked with champagne and cardamom, rose, and saffron chocolates. A column of water drops from the ceiling to fill the 40-jet indoor Jacuzzi; in the spa garden, a path of wet, smooth river stones proves a challenging and soothing reflexology session. Relax on the outdoor daybeds (where Thai massage can be arranged), inside the cedar-scented Finnish sauna, or on heated marble benches, cooling down with a handful from an ice fountain. In the Warm Jade Stone Massage ($202), experienced therapists nestle semiprecious stones into achy joints and muscles, accompanied by oils including Himalayan cedar, white grapefruit, naroli, and cypress. A final swoosh with cold stones is applied to rebalance (massages, $130).
