Freeflow Cascina: The Cascina spa was designed to bring you maximum comfort at a minimum price. The smallest spa in the Freeflow line up sits much deeper than other spas of comparable size. It has a built-in cascading waterfall and is fully foamed to keep electricity costs low. A four person hot tub with 17 jets, the Cascina is also a 110V Plug-N-Play hot tub! This Cascina hot tub only comes in the Espresso color, and comes with a hot tub cover and delivery of the hot tub.
