On a Royal Caribbean cruise in 2026, a single 500ml bottle of Evian or similar premium water typically costs around $3.25 to $4.00, plus an automatic 18% gratuity. However, most savvy cruisers buy a Water Package pre-cruise via the Cruise Planner app, which can bring the price down to about $2.00 per bottle when purchased in bulk (e.g., a 12-pack or 24-pack delivered to your stateroom). If you have the Deluxe Beverage Package or the Refreshment Package, unlimited bottled water is included in your daily rate. It is important to remember that the tap water on Royal Caribbean ships is highly filtered and perfectly safe to drink; many travelers in 2026 choose to bring a reusable insulated bottle and fill it at the Windjammer buffet or various water stations around the ship to save money and reduce plastic waste. Note that you are also generally allowed to bring up to 12 cans or bottles (non-alcoholic) per stateroom during embarkation.
