A new discovery for us, Agua Spa is located under the hypermodern Sea Containers hotel (formerly the Mondrian) and designed by Tom Dixon. It’s the antithesis of a normal spa. There are no hard corners, only undulating surfaces that curve into corridors and communal spaces, and the color scheme is white, grey, and silver. The whole vibe is more akin to a spaceship or a futuristic cocoon than the usual wood/cotton/natural-light mix. The manicures and pedicures are both indulgent and blessedly efficient, but of all the treatments, the Soveral Signature Facial is one we come back to again and again. If you’re into lymphatic massage, aromatherapy, and nontoxic beauty, you won’t be disappointed. We also found ourselves in the womblike relaxation area sipping herbal tea and reading newspapers (thoughtfully left by each bed) long after our appointment ended.
