About 504 55 Th Avenue

This exceptional waterfront estate in coveted Brightwater Beach Estates offers a rare combination that is nearly impossible to replicate: deep-water boating, panoramic Boca Ciega Bay views, and the beautiful sands of the Gulf of America just across Gulf Boulevard. Set within an intimate waterfront neighborhood of approximately 100 homes, Brightwater Beach Estates is one of St. Pete Beach’s most desirable coastal enclaves. From here, you can walk across the street to the Gulf beaches, enjoy nearby restaurants, cafés, shopping, and entertainment, and be in vibrant Downtown St. Petersburg in approximately 10 minutes. Positioned on deep, open water with sweeping views of Boca Ciega Bay and the iconic Don CeSar, the residence has been thoughtfully designed for both sophisticated entertaining and relaxed coastal living. Soaring ceilings, expansive windows, and abundant natural light frame the water views throughout the home. The gourmet kitchen features Sub-Zero, Wolf, and Bosch appliances, a gas cooktop, custom cabinetry, and elegant stone finishes. The main-level primary suite offers private waterfront views, a spa-inspired bath, and a custom walk-in dressing room. Upstairs, a spacious media and game lounge with a wet bar creates an exceptional entertaining space, complemented by a guest suite and private balcony overlooking the bay. Outside, the property becomes a private waterfront resort with a heated PebbleTec saltwater pool and spa, multiple areas for lounging and dining, tropical landscaping, and a newer composite dock equipped with water and electricity. A 20,000-pound boat lift and deep-water access make it effortless to enjoy Tampa Bay and the Gulf beyond. Additional features include hurricane-impact windows and doors, smart-home automation, travertine flooring, plantation shutters, custom lighting, a newer roof with hurricane clips, and an impressive four-car garage with ceiling height suitable for vehicle lifts—an outstanding amenity for the car collector. Priced below a recent appraisal, this beautifully refinished, turn-key estate represents an extraordinary opportunity to own the complete St. Pete Beach lifestyle: boating from your backyard, Gulf beaches across the street, dining and shopping moments away, and Downtown St. Petersburg just minutes from home. Luxury. Waterfront. Beach. Boating. Location. This is Brightwater Beach Estates. This is luxury living in Tampa Bay.
