A square surround conceals the interior, only revealing the circular opening to the eye. The ergonomic interior offers arm or footrests for the tall and supports for the not-so-tall. With a generous depth of 53 cm, the user floats in the warm water and almost feels weightless. Blue Moon features plenty of practical details such as a shaped insert, neck supports, and a bench. The round tub literally becomes a Blue Moon with the colored lighting module. The installation options include free-standing, corner, or back-to-wall choices. There is a choice of simple white acrylic paneling or furniture paneling for all tub models.
