The water was clean and freezing; it felt colder than the time I did a pure ice bath last year with a Wim Hof group. The circulation jets on this cold plunge prevent warm water from accumulating near your skin automatically, so it will be as always be as cold as you want it to be. Installation was a breeze with two people and fit through a small patio door and it was easy to navigate up two flights of narrow L and U shaped staircases.
