On a Royal Caribbean ship in 2026, you can safely drink tap water in your cabin bathroom, as it is produced via high-tech desalination (reverse osmosis) and regulated by the CDC's Vessel Sanitation Program. For more convenient access, there are free water stations located in the Windjammer Marketplace (buffet area) and near the fitness center or pool decks. For hygiene reasons, you are usually asked to fill a clean glass first and then pour it into your personal reusable bottle rather than filling the bottle directly from the dispenser. If you prefer bottled water, the "Water Bottle Package" (12 or 24 bottles) can be pre-purchased and delivered to your stateroom. While premium bottled water in the mini-bar is a charged item, many high-tier loyalty members receive complimentary bottles daily. Using a refillable bottle at the buffet stations or your cabin sink is the most sustainable and cost-effective way to stay hydrated.
