In-Ground Hot Tub Prices. Prefabricated hot tubs are the less expensive of the two options. Acrylic shells range in price from about $3,000-$10,000. Installation adds about another $3,000-$5,000 to the total purchase price.
Portable spas average between $2,000 and $12,000, depending on size and features. In-ground spas average between $15,000 and $20,000.
