You bought a 24-pack of water near the port and wheeled it to the terminal, feeling very organized.
Then security on a Carnival, Princess, Norwegian or Holland America ship took the lot.
Plastic water bottles are the one drink container most big cruise lines refuse at the gangway. The good news: you almost certainly don’t need them.
Can You Bring Water on a Cruise?
Usually yes, but rarely in plastic bottles. Carnival, Princess and Virgin Voyages allow 12 sealed cans or cartons per person and ban bottles. Holland America allows water only in cans or cartons, up to 6 liters per cabin. Royal Caribbean allows 12 bottles, cans or cartons per cabin, Celebrity and Disney allow what you can carry, and Norwegian and MSC allow none at all. On every line, the tap water on board is treated to CDC standards and safe to drink.

What Each Line Lets You Carry On
“Per person” and “per cabin” make a big difference for a family of four, so watch which one your line uses.

|---|---|---|---|
| Carnival | 12 sealed cans or cartons of 12 oz or less, per person | No, glass or plastic | Distilled CPAP water, hand-carried with the machine |
| Princess | 12 sealed cans or cartons of 12 oz or less, per person, embarkation day only | No | Not covered in the contract clause |
| Virgin Voyages | 12 sealed cans or cartons of 12 oz or less, per person, hand luggage only | No, glass or plastic | Not covered on the list |
| Royal Caribbean | 12 cans, bottles or cartons of 17 oz, per cabin, boarding day | Yes | Distilled water for infant, medical or dietary use |
| Celebrity | Anything each person can hand-carry, embarkation day only | Yes | No limit needed |
| Disney | Sealed water in your carry-on | Yes | No limit needed |
| Holland America | 6 liters per cabin: 12 cans or cartons of 500 ml, or 6 of 1 liter | No, “in any quantity” | Factory-sealed water in checked bags, packed with the device |
| Norwegian | None | No | Sealed purified or distilled water, approved in advance |
| MSC | None | No | Sealed purified or distilled water, per Cruise Mummy |
Two details catch people out. Holland America says “Plastic water bottles are not allowed in any quantity, including in ports of call,” so its 6 liters has to come in cans or cartons. And Norwegian’s FAQ says drinks bought ashore are thrown away before you board, with “no open containers, including water,” allowed back on during a port call.
Why Do Cruise Lines Ban Water Bottles?

Because a water bottle is the easiest place to hide vodka. Carnival banned bottled water and soda from July 9, 2015, and Cruise Fever reported at the time that the reason was passengers sneaking alcohol aboard. Carnival’s letter to guests, quoted by Fox News, said the line believed the change would “result in a safer environment while also improving the embarkation process.”
Is the Tap Water on a Cruise Ship Safe to Drink?
Yes, and the rulebook behind it is stricter than most people expect. Royal Caribbean’s FAQ says all its drinking water “is either distilled from seawater or loaded onboard while the ship is in port,” and that it follows the U.S. Public Health Service’s Vessel Sanitation Program (VSP). That program, run by the CDC, inspects every ship with 13 or more passengers on an international voyage calling at a U.S. port, twice a year and unannounced.
Here is what the CDC’s 2025 VSP Environmental Public Health Standards actually require. The same rules appear in the 2018 Operations Manual they replaced.
- No making water in port. The desalination plant “must only operate while the vessel is MAKING WAY. These processes must not operate in polluted areas, HARBORS, or at anchor.”
- No recycled water. “Air conditioning condensate, or wastewater of any kind (treated or untreated) are not allowed” for drinking water production.
- Port water gets checked first. Before loading water ashore, the ship needs the port’s lab report, no more than 30 days old and including an E. coli test, or must test the water itself.
- Chlorinated going in. Water must be dosed to at least 2.0 mg/L of free chlorine (or another halogen) within 30 minutes of starting to load or make it.
- Chlorinated all the way to your tap. Between 0.2 and 5.0 mg/L throughout the pipes, with recorders proving it for at least 16 hours in every 24.
- Tested every month. At least four samples a month for E. coli, taken from the forward, aft, upper and lower decks, with the sample points changed each month.
In short, the water in your cabin tap comes through a tested, chlorinated system. Islands reached the same conclusion, and Cruise Mummy quotes Norwegian and Royal Caribbean saying their onboard water is safe to drink. If you don’t like the taste, that’s a reason to buy bottled. Safety isn’t.
Where to Get Free Water on Board

All the big lines have free water somewhere on board. The question is how easy it is to fill a bottle.
- Virgin Voyages is the easiest. Its drinks FAQ lists “filtered still and sparkling water” as free, with Natura self-serve filtered water stations around the ship.
- Celebrity lists “non-bottled water” among its free drinks on its onboard FAQ.
- MSC is switching to AQUA by MSC, filtered seawater with added minerals. Cruise Industry News reports it should be fleetwide by the end of 2026. Plain water from the buffet dispensers stays free. AQUA costs €0.50 a glass, €1 per refill at the self-serve stations or €2 for a one-liter bottle in the main restaurants, and is unlimited with a drinks package.
- Carnival, Royal Caribbean and Holland America all have buffet water dispensers. Cruise Hive reported in 2024 that Carnival welcomes reusable bottles and tumblers, but that signs at the Lido drink stations ask guests not to refill large bottles there. Cruise Mummy gives the same tip for all three: fill a cup, then pour it into your bottle.
What Does Bottled Water Cost on a Cruise?
Carnival publishes its prices. Here’s what its FAQ charges, with the 20% delivery fee already included, and what that works out to per liter:
- 12 bottles of 500 ml (6 liters): $19.20, or $3.20 a liter
- One 1.5-liter bottle: $5.40, or $3.60 a liter
- 8 bottles of 1.5 liters (12 liters): $29.94, or about $2.50 a liter
Unopened bottles can go home with you. For Norwegian, Cruise Mummy lists 12 half-liter bottles for $19.95, 24 for $34.95 and 48 for $49.95, plus service charges. Carnival’s CHEERS! drinks package includes 500 ml bottled water and Bottomless Bubbles doesn’t.
CPAP Machines and Baby Formula

Even the strict lines bend here, if you do it their way:
- Norwegian allows factory-sealed purified or distilled water for medical devices or infant formula, and asks you to get approval first from [email protected].
- Holland America allows factory-sealed purified or distilled water, plastic containers included, in checked luggage, packed with the medical device. Formula water is allowed for cabins with an infant booked.
- Carnival sells distilled CPAP water before or during the cruise. If you bring your own, it must be hand-carried with the machine.
- Royal Caribbean says “Milk and distilled water brought on for infant, medical, or dietary use are permitted.”
What to Pack Instead of a Case of Water
Bring an empty reusable bottle. The rules above limit drinks, not empty containers, and Carnival says reusable bottles and tumblers are welcome. On Holland America, whose rule bans plastic water bottles “in any quantity,” a metal bottle avoids any argument at the scanner.
If you want sealed water, buy cans or cartons. Boxed or canned water passes on Carnival, Princess, Virgin and Holland America, within each line’s count. Put it in your carry-on, since Princess, Virgin and Disney require that.
Quick Answers
Can you bring water back on board from a port?
On Carnival, a small quantity in cans or cartons is allowed back aboard in port. Princess limits its allowance to embarkation day. Norwegian throws away drinks bought ashore, and Holland America bans plastic water bottles in ports too.
Can you bring sparkling water on a cruise?
On Carnival and Princess, yes, if it’s in cans or cartons. Both name “sparkling water” in their allowance of 12 cans or cartons of 12 ounces or less per person.
Can you order bottled water before your cruise?
Yes, on most big lines. Carnival delivers pre-ordered water to your cabin on embarkation day, and a planDisney answer says Disney sells packs of 6, 12 or 24 bottles that are waiting in the cabin when you arrive.
