In 2026, the strict rule for almost every cruise line (including Carnival, Royal Caribbean, and Disney) is that you cannot bring any clothes iron or steamer on board. These are classified as major fire hazards because they feature unshielded heating elements that can easily be left on in a small cabin. If a security scan detects an iron or steamer in your luggage, it will be confiscated and held until the end of the cruise. Instead of bringing your own, you have three options in 2026: use the self-service laundry rooms found on many ships (which provide free-to-use irons and boards), pay for the ship's professional pressing service, or bring wrinkle-release spray. Some lines like Virgin Voyages have broken the mold by providing high-quality steamers in certain suites, but for the general passenger in 2026, "personal heating appliances" remain on the prohibited items list to ensure the safety of the thousands of people on the vessel.
