Sundance® Spas ⋅ 780 Series ⋅ Chelsee ⋅ 6–7 Person Hot Tub

Chelsee

The Chelsee from the Sundance® 780 Series is crafted for those who want generous seating and diverse hydrotherapy in a welcoming, social layout. With room for up to seven adults, it offers the series’ widest range of specialized seats, each designed to ease tension and restore comfort. Adjustable Fluidix® jets deliver both high- and low-impact relief, while the series-exclusive SMT Seat mimics the feel of a hands-on massage across the neck and back. The deep-tissue Accu-Pressure™ Seat targets fatigued muscles, and a low-profile foot dome brings soothing balance from head to toe — creating a spa experience where stress naturally fades away.
