It’s not “just” a pool, however. _Ilona’_s new water retreat measures 33 feet (10.5 meters) long by about 10 feet (3 meters) wide. Furthermore, it has a floor that can rise from its five-foot (1.5-meter) depth after the water is drained to meet the level of the deck. (The pool holds 10,567 gallons, or 40,000 liters, of filtrated and heated sea water, by the way.) This way, the area can handle a large party or other need.
