“In general,” he explained, “most cruise ships still use free-flowing seawater in their pools (the water is passed through a sand filter before it reaches the pool).”

Cruise ship swimming pools do usually contain chlorine and have filters that clean the water but changing the water at night guarantees that the water is as clean as possible.
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.
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.
Do Cruise Ships Dump Sewage? Yes. To get into a few more specifics than above, the U.S. allows cruise ships to dump treated waste into the ocean if they are within three and a half miles from shore. Beyond that point, there are no restrictions for dumping untreated, raw sewage in U.S. ocean waters.

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.
Many cruise ships have self-service laundry facilities on each deck, including washing machines, dryers, ironing and detergent. Passengers can also use the ship's valet laundry services for a fee, which includes washing, pressing and dry cleaning. Alternatively, guests can hand wash and dry within their cabin.
Yes, all Royal Caribbean ships have a procedure in place to ensure that the swimming pools are drained, cleaned and sanitized. Where are the onboard swim vests located? Swim vests are located on the pool deck. Lifeguards and Pool Attendants can assist all guests to the nearest location.
The depth at which a ship sits in the water is known as the draft. Most cruise ships typically have a draft of between 5 metres (16ft 5in ) and 10 metres (32ft 10in). The actual draft depends on the size of the vessel and how much fuel and ballast water is on board. A typical cruise ship draft is 8.5m (25ft 6in).
Someone swimming near a cruise ship could be sucked under by the propulsion power. The power can also cause large sudden swells of water which is very strong. Not long ago the Carnival Vista destroyed a small marina in Italy as it got too close.
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.
Children who are not toilet trained (and those in diapers or swim diapers) are not allowed in any of the water facilities on board, as per United States Public Health Services. Toilet trained children should be taken on frequent bathroom breaks. Water sports include pools, spray parks, waterslides and whirlpools.
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.
It is winter in the northern hemisphere, ocean temperatures are cooler and since cruise ship pool water is drawn from the ocean, it reflects the same temperature. Pool water during the summer can be considerably warmer due to higher air temperatures and warmer ocean temperatures.
Saltwater pools can be just as sanitary, plus the water feels smoother and fresher. Many owners of swimming pools have chosen to switch from chlorine to saltwater for these reasons, and because saltwater can mean lower maintenance costs and easier upkeep.
