Benefits of this Spa Pool: The Galaxy Ceres is the perfect couple’s spa pool. Relax together in the dual loungers while its 30 jets provide therapeutic massage and work away the knots and stresses of the day. More compact in size, it’s also a great solution for smaller outdoor spaces or if fewer people will be using the spa. For a step up in hydrotherapy features and to keep your long term running costs down even further, check out the Venus or Capella models.
