No, you cannot bring an iron—even a "travel-sized" or "small" one—on a cruise ship in 2026. This is a universal policy across all major cruise lines, including Royal Caribbean, Carnival, and Norwegian, due to the extreme fire hazard they pose in the high-density environment of a ship. Irons are among the most common items confiscated during the security X-ray process at the embarkation terminal. If an iron is found in your luggage, it will be removed and held at the "Naughty Table" until the end of the cruise. Instead of bringing your own, most 2026 cruise ships provide self-service laundry rooms on several decks that contain irons and ironing boards for public use, which are equipped with automatic shut-off timers. Alternatively, you can pay for professional pressing services through the ship's laundry department. Many travelers in 2026 also utilize wrinkle-release sprays or "steaming" clothes in the bathroom while taking a hot shower, as both are safe and permitted alternatives to traditional irons.
