Do cruise ships provide distilled water? Yes, many cruise lines will provide a gallon of distilled water in your stateroom provided you notify them in advance that you will be bringing a CPAP. You can do this by going to the cruise line's website and submitting a guest special needs form.

Yes, cruise ships provide distilled water, but it is generally intended for guests who need it for medical devices like CPAP machines or for preparing infant formula. In 2026, major lines like Carnival, Royal Caribbean, and Norwegian (NCL) allow you to pre-order a gallon of distilled water through their online "In-Room Gifts" or "Medical Needs" portals for a small fee (usually between $3 and $5). If you wait until you are on board, you can request it through your stateroom steward or guest services. While most ships technically produce their own "evaporated" water that is safe, pure distilled water is kept in stock for medical compliance. A "pro-tip" for 2026 cruisers is to pack a long extension cord along with your distilled water request, as older ships often have limited power outlets near the bed, and cruise lines require you to use their approved cords for safety to avoid fire hazards from uncertified personal power strips.
