Ocean Three · #601

Ocean Three is a 37-story oceanfront condominium at 18911 Collins Avenue in Sunny Isles Beach, completed in 2003 as the third tower in The Related Group's Ocean series. Rising about 405 feet on roughly 300 feet of ocean frontage, it sits just south of the William Lehman Causeway at the north end of the city. Miami-Dade property records list 215 residences. Seven homes share a typical floor on the 01 to 07 lines, five share the two floors below the top, and the 37th floor holds a single penthouse of about 5,900 square feet. The 02 and 03 lines are two-bedroom plans of about 1,591 square feet and the 04 line about 1,903 square feet; the 06 line is a flow-through plan of about 2,136 square feet with ocean and Intracoastal exposures; and the larger 01, 05 and 07 lines run about 2,650 to 4,160 square feet, with the 01 line at about 3,945 square feet and three or four bedrooms. Most residences open from a private elevator foyer, and listings cite floor-to-ceiling impact glass, honed marble floors, eat-in kitchens, separate laundry rooms and wraparound balconies. The largest plans come with up to three assigned parking spaces and a storage unit. At ground level, Ocean Three has a renovated heated pool and beach pavilion with full pool and beach service, an on-site bistro, lighted tennis courts and pickleball. The fitness center sits alongside a spa with sauna, steam and a massage room, a billiards and game room and a party room, and a rooftop deck has a jacuzzi with panoramic views. A limited number of privately owned oceanfront cabanas with baths and kitchenettes trade separately; one was offered for $500,000 in 2026. Services include a 24-hour front desk and security, concierge and valet. Heritage Park at 19200 Collins Avenue and the Lehman Causeway to Aventura Mall are a few blocks north, and the beachfront restaurants and shops of central Sunny Isles Beach are to the south. Bal Harbour Shops is a short drive down Collins Avenue. Ocean Three's resale prices span a wide range because the building mixes compact two-bedroom lines with large multi-bedroom plans.
