Most cruise lines prohibit bringing your own bottled water onboard
You cannot bring bottled water in your carry-on or checked luggage on most cruise ships. Major lines including Carnival, Royal Caribbean, Disney Cruise Line, and Norwegian Cruise Line all ban outside beverages as part of their standard policies. The rule applies whether the bottles are sealed or opened, and whether you bought them at the airport or packed them at home.
The restriction exists because cruise lines generate significant revenue from onboard beverage sales, and they enforce the policy consistently at the gangway. Security staff will confiscate water bottles during the boarding process, and you will not get them back. Some lines allow you to bring an empty reusable bottle that you can fill at water fountains once onboard, but policies vary by cruise line and sometimes by ship within the same line.
Key Takeaways
- Sealed and unsealed bottled water are prohibited in carry-on and checked bags on virtually all major cruise ships.
- You can bring an empty reusable water bottle and refill it at drinking fountains and water stations throughout the ship.
- Tap water on cruise ships is safe to drink and meets or exceeds U.S. Environmental Protection Agency standards.
- Some cruise packages include beverage packages that cover bottled water, soft drinks, and alcoholic drinks at no additional cost per drink.
- If you have specific medical or dietary needs for bottled water, contact your cruise line before boarding to request an exception.
Why cruise lines enforce the bottled water ban
Cruise lines ban outside beverages to protect their beverage revenue model. A seven-day cruise with bottled water purchases can cost $50 to $100 per person if you buy multiple bottles daily. When multiplied across thousands of passengers, this becomes a substantial income stream. The policy also simplifies security screening at embarkation and reduces waste management on the ship.
The ban is not about safety—tap water on cruise ships is regularly tested and is safe. It is purely a commercial decision. Cruise lines explore the same logic to other outside food and beverages: you cannot bring your own soda, juice, beer, or wine either. The only common exception is medication in liquid form, which security will allow if you can show a prescription or medical documentation.
What to do instead: reusable bottles and water stations
Bring an empty reusable water bottle—stainless steel, plastic, or collapsible—and fill it at the water fountains and beverage stations scattered throughout the ship. Most cruise ships have drinking fountains on multiple decks, in the buffet area, near the pool deck, and in cabin hallways. The tap water is potable and safe, drawn from the ship's desalination systems or stored freshwater tanks that meet international maritime standards.
If you prefer not to drink tap water, you have two paid options. You can purchase individual bottled waters at the ship's convenience store or bar, typically priced between $2 and $5 per bottle depending on the cruise line and bottle size. Alternatively, you can purchase a beverage package before or during your cruise that includes bottled water, soft drinks, specialty coffees, and sometimes alcoholic beverages. These packages range from $15 to $80 per person per day depending on what is included and which cruise line you are sailing with.
Beverage packages and what they cover
Most major cruise lines offer tiered beverage packages. A basic package typically covers non-alcoholic drinks: bottled water, sodas, juices, coffee, and tea. A premium package adds alcoholic beverages like beer, wine, and cocktails. Some lines also offer specialty packages focused on wine or craft beer. Prices and inclusions vary significantly by cruise line, ship, and sailing date.
Beverage packages are usually cheaper per drink than buying individually over a week-long cruise, especially if you plan to drink multiple beverages daily. However, they require an upfront commitment and you pay whether you use the full value or not. If you drink sparingly, buying individual bottles or sticking with tap water is more economical. Check your cruise line's website or call their customer service to see current package pricing and what each tier includes before you book or board.
Medical or dietary exceptions to the bottled water rule
If you have a documented medical condition that requires specific bottled water—such as a prescription for distilled water or water from a particular source—contact your cruise line's guest services or medical department at least two weeks before your sailing date. Provide a letter from your physician explaining the medical necessity. Some cruise lines will make exceptions for legitimate medical needs, though approval is not may provide and varies by line.
Similarly, if you have severe gastrointestinal sensitivity to tap water or desalinated water, document this with your doctor and contact the cruise line in advance. The ship's medical staff can sometimes provide alternatives or work with you on solutions. Do not assume an exception will be granted, and do not attempt to sneak bottled water through security—confiscation is certain and you will have no recourse.
What happens if you try to bring bottled water onboard
Security staff at the gangway will inspect your luggage during the boarding process. Any bottled water they find will be removed and discarded. You will not receive a refund, and the cruise line will not hold the bottles for you to retrieve at the end of the cruise. This applies to sealed bottles you purchased at the airport, bottles you packed at home, and any other outside beverages.
The confiscation is not punitive—it is standard procedure. Cruise lines do not make exceptions based on how much you paid for the water or how far you traveled. The policy is applied uniformly to all passengers. If you forget about a water bottle in your bag and it is discovered, straightforward accept the loss and move forward with your cruise.
