You can bring water on a Carnival cruise, but only sealed, unopened bottles
Carnival allows passengers to board with bottled water, but the bottle must be factory-sealed and unopened. Once you open it, you cannot bring it into your cabin or onto the ship. This rule applies to all non-alcoholic beverages in sealed bottles — juice, soda, sports drinks, and flavored water all follow the same restriction.
The reason for this policy is straightforward: Carnival wants to prevent passengers from bringing their own alcohol disguised as other drinks, and they want to control what goes into the ship's water and waste systems. A sealed bottle proves the contents are what the label says they are.
If you open a bottle before boarding or during the security screening process, you will have to throw it away. Screeners at the gangway check bags and will confiscate any open beverages, even if they are just water.
Key Takeaways
- Sealed, unopened bottles of water and other non-alcoholic drinks are permitted in your carry-on bag when you board.
- Once a bottle is opened, you cannot bring it aboard, and screeners will throw it away if they find it.
- Carnival provides free tap water in your cabin and at water fountains throughout the ship, so you do not need to pack large quantities.
- If you want bottled water during the cruise, you can purchase it at the ship's shops, or bring sealed bottles and open them after you board.
- The policy is the same across all Carnival ships and does not change based on the length of your cruise.
What happens to water you bring through security
When you arrive at the port and go through the security checkpoint, a screener will look through your carry-on bag. If they see a sealed bottle of water, they will let it through. If the bottle is open or partially full, they will ask you to throw it away or will confiscate it themselves.
This happens quickly — you do not have a chance to drink it down or reseal it. The screener's job is to verify the seal is intact, not to test the contents. A bottle with a broken seal or a missing cap will be treated as open.
After you pass through security and board the ship, you can open your sealed bottles and use them in your cabin or carry them around the ship as you wish.
Free water sources on the ship
Carnival provides tap water at no charge in your cabin, in the dining room, at the buffet, and at water fountains scattered around the ship. You can ask for a glass of water at any bar or restaurant, and they will give it to you free of charge — this is one of the few things that does not cost extra on a cruise.
The tap water on Carnival ships is safe to drink. It comes from the ship's desalination system, which converts seawater to fresh water. If you are concerned about the taste or have a sensitive stomach, you can drink bottled water instead, but you do not have to bring it from home.
Many passengers bring a reusable water bottle and fill it from the tap or at water fountains. This saves money and reduces waste, and Carnival does not charge you for doing this.
Buying bottled water on the ship
If you did not bring sealed water bottles or you run out, you can buy bottled water at the ship's convenience stores and at some bars and restaurants. A single bottle typically costs between $2 and $4, depending on the size and where you buy it. Prices are higher than you would pay on land because everything on the ship has to be shipped and stored.
Some Carnival packages include a beverage plan that covers bottled water, so check your booking documents to see if you have one. If you do, you can get bottled water included without paying extra per bottle.
You can also order bottled water to be delivered to your cabin by calling room service, though this usually comes with a delivery charge in addition to the cost of the water itself.
Other drinks you can bring sealed
The same rule that applies to water applies to juice, sports drinks, flavored water, soda, and any other non-alcoholic beverage in a sealed bottle. You can bring one sealed bottle of each type if you want variety. Alcohol is not permitted in carry-on bags under any circumstances — Carnival has a strict no-outside-alcohol policy.
If you have a medical condition that requires a specific drink — such as a particular brand of electrolyte replacement or a prescription beverage — bring it sealed in your carry-on. Screeners understand medical needs and will not confiscate something that is clearly labeled as a medical product.
Powdered drink mixes and individual drink packets are allowed, because they are not liquids. You can bring as many as you want and mix them with tap water in your cabin.
What to do if you forget to bring water
If you board without any bottled water, you have several options. The simplest is to use the free tap water available throughout the ship. If you prefer bottled water, you can buy it at the ship's shops or order it to your cabin.
Some passengers ask their cabin steward (the crew member assigned to clean your room) if they can provide bottled water. Stewards sometimes have access to complimentary bottles and may be willing to help, though this is not may provide and may depend on availability.
If you are staying in a suite or have a premium cabin, your package may include complimentary bottled water delivered to your room daily. Check your booking confirmation or ask at the front desk when you board.
Bringing water for children and special diets
If you are traveling with young children, you can bring sealed bottles of water, juice, or formula. The same rule applies — the bottle must be unopened when you go through security. Once you board, you can open bottles and use them freely in your cabin or around the ship.
If your child needs a specific type of drink for medical reasons, bring it sealed and explain the situation to the screener if asked. Screeners are trained to accommodate medical needs and will not hold up the boarding process for a legitimate health requirement.
For passengers on special diets, tap water is always available. If you need a specific beverage, bring it sealed or purchase it on the ship.
Frequently Asked Questions
Can I bring a water bottle and fill it at the airport before boarding?
No. If you fill a water bottle at the airport and bring it to the ship, it will be treated as an open bottle and confiscated at security. You must bring factory-sealed bottles only. You can fill a reusable bottle after you board the ship.
What if I have a sealed bottle but the seal looks damaged?
A screener will not let it through. If the seal is broken, torn, or appears tampered with, they will treat it as an open bottle and ask you to throw it away. Bring bottles in good condition, and inspect them before you pack them.
Can I bring a large case of water bottles?
Yes, as long as each bottle is sealed and unopened. There is no limit on the number of sealed bottles you can bring in your carry-on or checked luggage. However, checked luggage has weight limits, so a full case may not fit. Many passengers bring a few sealed bottles in their carry-on and leave it at that.
Do I have to pay extra if I bring my own water?
No. Bringing sealed bottled water does not cost anything extra, and using tap water in your cabin is free. You only pay if you buy water from the ship's shops or order it through room service.
Can I bring water in a hydration pack or water bladder?
No. Hydration packs and water bladders are considered open containers because they are designed to be filled and used. They will be confiscated at security. Stick to sealed bottles only.
