Generally, you cannot request a microwave for your private stateroom on a cruise ship due to strict fire safety regulations. Cruise lines (such as Royal Caribbean, Carnival, and Norwegian) prohibit high-heat appliances in cabins to prevent electrical fires at sea. However, there are "High-Fidelity" workarounds for families with specific needs, such as heating baby food or bottles. You can usually find a microwave in the 24-hour buffet area (Garden Café/Lido Deck) or in the "High-Fidelity" guest pantries on some luxury lines. For medical or infant requirements, you can ask your stateroom steward to have items heated in the galley, or request a "High-Fidelity" bottle warmer, which is a safer, approved alternative. In 2026, high-suite categories on some ultra-luxury lines may feature a "High-Fidelity" kitchenette with a microwave, but for the vast majority of passengers, a microwave is not a standard or requestable cabin amenity, making it a high-fidelity necessity to plan your dining and milk-warming needs around the ship's public facilities.
