As of March 2026, the Icon of the Seas (and its sister ship, the Star of the Seas) holds the record for the biggest pool at sea, known as Royal Bay. Located in the "Chill Island" neighborhood, Royal Bay spans over 5,800 square feet and contains over 40,000 gallons of water. It is part of a massive aquatic complex that features seven different pools, including the first suspended infinity pool at sea (The Hideaway). Royal Caribbean designed Royal Bay to be the centerpiece of the ship’s outdoor experience, featuring integrated loungers and "water's edge" seating to accommodate thousands of guests simultaneously. For context, this single pool is nearly twice the size of the main pools found on many mid-sized luxury liners. The ship also features the largest water park at sea, "Category 6," which includes six record-breaking slides, further cementing its status as a floating water-world.
