It was only earlier this year that Aqua Technics released more shapes to choose from. Here are 3 more! The Piazza Series new Palazzo 7m x 3.5m (always waterline measurements), which sits in between the very popular Empire and Valentina models. The Villa Series Paradiso 5.5m x 2.15m and Sentosa 6.m x 2.15m with generous deep-ends and giant entry steps for that off the deck or alfresco living environment.
