A new, and final, oceanfront estate-style penthouse is up for grabs for $75 million at Rivage Bal Harbour, a 25-story, 56-residence tower developed by Related Group, Rockpoint, and Two Roads Development. A standout feature is its dedicated "Longevity Suite"— an in-home wellness wing anchored by an “Ammortal Chamber” and hyperbaric chamber, alongside a sauna, steam room, circadian lighting throughout the residence, advanced air and water purification systems, sleep-optimized bedrooms and more.
