Inspiration: The Modern Bel

RELAXATION ROOM This unisex space opens out onto a patio. Inside, walls are covered floor to ceiling by a wide oak paneling that has cerusing (a technique in which an artisan paints the wood and then wipes it off so only suggestions of color remain). “We wanted this room to shift in feeling from the rest of the spa and feel simple and luxurious,” says Kastl.

Made-to-order side tables (by Argent Custom Furniture) reference tree stumps, sconces (by Laura Spector Design) are shaped like topiary and chaises are covered in layers of natural fiber textures. A striking gold-plated chandelier hangs at an atypical length, casting unusual patterns of light onto the ceiling. “We wanted something quirkier for this room,” says Kastl, “Something fun and luxe that reminds you of how special this spa is. It’s a rich detail that communicates that life is good.”
