I believe Disney and Princess are the only cruiseline's that use fresh water in their pools. They use salt water because they can pipe it directly from the ocean without having to run it through the plant.

Most cruise ship water is desalinated sea water. The process usually involves steam evaporation -- essentially turning saltwater into distilled water. That water is then mineralized for flavor and chlorinated for extra safety. Other ships are fitted with a reverse-osmosis system for filtering and/or desalination.
Shipboard potable water (drinking, bathing, whirlpools, etc.) either comes from a shoreside water treatment plant or is generated on board from seawater via Reverse Osmosis systems or Evaporators. Swimming pool water is typically seawater.
Cruise lines drain their swimming pools at night to discourage guests from trying to enter the pool when it is closed. Draining the swimming pools each night also allows the cruise lines to replace the water with clean water and a drained swimming pool is safer if the weather is rough.
When do The Swimming Pools Close? On most cruise lines, the swimming pools are open from early morning until the evening. On some cruise lines, you'll find the pools and hot tubs open late into the evening which I particularly enjoy. There's not a lot better than an evening swim beneath the stars!
The pools are small due to Free Surface Effect. The more room water has to slosh back and forth, the more unstable the ship becomes. The fact that the pools are typically on the highest deck only furthers the need for them to be small.
While, yes, underwater cruise ship rooms do exist, they aren't staterooms or suites that passengers can stay in. Instead, the rooms below the waterline are meant for crew members.
In general, you'll find at least one pool, flanked by one or more hot tubs, plus showers for rinsing off and rows of lounge chairs for sunbathing. Pools are typically small and no deeper than 5 or 6 feet.
When a toilet is flushed on a cruise ship, the sewage travels to the onboard treatment plant. Here the waste is filtered before it enters an aeration chamber. The aeration chamber cleans the waste. It is then sterilized using UV light and released into the ocean when clean enough to do so.
Doctors say these symptoms likely come from the vestibular system, the mechanism in our inner ears that help control balance and equilibrium. If resetting that system takes a while post-cruise, you could end up with sea legs.
Cruise ship pools are usually filled with saltwater which has been chemically treated. On some cruise ships, you will find freshwater pools but these are less common. It is possible to have a cruise ship where some pools are fresh and some saltwater, this is very common on Royal Caribbean cruise ships.
Shorts, jeans, flip-flops, hats and T-shirts are prohibited throughout the ship during the evening. As with other lines, cruises in tropical waters tend to make dressing down more acceptable, as do voyages on the line's sailing vessels.
There are no rules that say that passengers on cruise ships can't sleep on their balconies. That said, cruise lines do generally advise against it. Many people enjoy sleeping on their balconies, and you won't have any problem if you want to do so too.
In general, cruise ships provide all of the towels you need. This means that you don't only get bath, hand, and face towels for your cabin, but you'll also be provided with beach towels for both swimming in the pool and swimming on your beach day excursions offshore.
Do Cruise Ships Travel Faster at Night? It's a common misconception that cruise ships travel faster at night than during the day. This is probably because cruise ships slow down as they enter and leave ports. Since most cruise ships only enter or leave ports during the day, it can seem like they travel faster at night.
Usually, this involves your cabin steward cleaning and sanitizing the bathroom, emptying trash bins, replacing towels, making the bed/beds, vacuuming as needed, refilling ice bins, washing and replacing glassware and a general tidying of the room.
Most ships can store 500,000 gallons of fresh water in massive tanks located in the hold area. After guests have used the water for showering, toilet water, laundry, etc., the crew treats it before releasing it into the ocean. A cruise ship will bring fresh water onboard when they visit ports.
Guests may also bring non-alcoholic beverages as carry-on items on boarding day. Non-alcoholic beverages may not exceed 12 standard (17 oz.) cans, bottles or cartons per stateroom. Milk and distilled water brought on for infant, medical, or dietary use are permitted.
Carnival Cruise Line: Carnival has one of the loosest beverage policies of all cruise lines, allowing each guest to carry on a maximum of 12 sealed 12 oz.cans or cartons of a non-alcoholic beverage (e.g., sodas, juices, milk, or sparkling water) – a policy that most cruise lines have eliminated.
Cruise ship tap water is safe to drink unless you are told otherwise by the ship's authorities. The water throughout the ship has been treated, filtered and frequently tested to meet the standards of the World Health Organization and the U.S. Public Health Service on ships sailing into and out of U.S. ports of call.
