An opulent Art Deco home gym features bookmatched walnut wall panels edged in brass with emerald inlays and zebra-pattern accents. A circular stained-glass window set in a marble arch with a brass sunburst anchors the space, with chrome-framed mirrors bouncing light from a ribbed globe pendant and spots. A tufted cognac leather bench and wood water rower sit on teal-and-ivory chevron rubber coin flooring.
