In 2026, the vast majority of modern cruise ship cabins (especially on major lines like Royal Caribbean, Carnival, and Norwegian) are equipped with a mini-fridge or a "cooling box." However, it is important to manage expectations: these are often not "true" refrigerators and are designed to keep drinks "cool" rather than ice-cold. On many ships, the fridge comes pre-stocked as a mini-bar with sodas, alcohol, and snacks that incur a high per-item charge. You can usually ask your stateroom steward to remove these items so you can store your own water, sodas, or temperature-sensitive medication. If you require a medical-grade refrigerator for insulin or other life-critical supplies, you should notify the cruise line's "Special Needs" department at least 30 days before sailing; they will often provide a dedicated, high-performance unit for your room at no extra cost. In the most basic "interior" cabins on much older vessels, a fridge might not be a standard feature, so always verify your specific "stateroom category" details before booking your cruise.
