One of the popular amenities on cruises are the Jacuzzis that are typically found on the exterior next to the pools, although some ships also have them in their thermal areas or spas, becoming increasingly common and with greater capacity for passengers to enjoy a relaxing bath with bubbles or hydro massage.
Jacuzzis on almost all cruise lines are usually filled with hot water and maintained with strict safety measures to keep the water clean and disinfected at all times, making it a plus. In addition, they are completely free unless they are in exclusive areas for the most select categories on the ship or are located inside the thermal area.
Furthermore, on more recent cruises, private jacuzzis can be found on the balcony of the cabin itself, with the Suite category being where they are available, but not all of them have this feature. So if you want to enjoy your own jacuzzi, you need to book in advance as they tend to sell out quickly.
