J-415 Hot Tub J-415 has 3 seats including a lounge: it’s very easy to get in and out of this model jam-packed full of features regardless of its compact size; it’s just perfect for any type of utilisation and for users of all ages. The original design that distinguishes J-415 is without the raised backrest that is typical of the collection. This makes entering the spa easier and facilitates installation in smaller spaces. The Water Colour™ waterfall provides additional excitement to the hydromassage experience provided by 21 adjustable Power Pro® jets. It is fitted with the Pro Clarity filtering system and provided with Clear Ray® technology and the SmartSeal™ coating that prevents heat dispersion and, consequently, reduces consumptions.
