780 Series - Hamilton

The Hamilton is the largest model in the Sundance Spas 780 Series — a proper family-sized hot tub that seats 5–6 adults comfortably. If you're looking for a spa that works equally well for a solo hydrotherapy session as it does for an evening with friends, this is the one to consider.

What sets the Hamilton apart within the 780 Series is the combination of a therapy lounge and a dedicated Accu-Ssage therapy seat. The therapy lounge lets you stretch out fully and receive a head-to-toe massage — jets work along your back, calves and feet in one continuous sequence. The Accu-Ssage seat delivers a deeply targeted massage to the back and shoulders, using precisely positioned jets that focus on the areas where most people carry tension. Between these two positions, you've got two very different but equally effective massage experiences in the same spa.

Five jet types are placed strategically across every seat — SMT Fluidix, SMT Micro Adjustable, Accu-Pressure, Vortex and Mini Vortex. The SMT Micro Adjustable jets are a standout feature of the 780 Series. They let you fine-tune the direction and intensity of the massage from each individual jet, so everyone can customise their experience without affecting anyone else's. The SMT Fluidix jets are bearingless with no moving parts — maintenance-free and consistent over time.

The side-by-side seating is designed for two people to sit next to each other comfortably, with wrist jets built into the armrests and calf jets in the half lounge. It's a sociable layout that makes conversation easy and adds extra massage points that most hot tubs don't include.

Four sets of neck jets are spread across four seats — two jets per seat targeting the tension-prone neck area. These are adjustable, so each person can direct the massage exactly where they need it. Combined with the pillow headrests for support, it makes longer sessions noticeably more comfortable.

The illuminated AquaSheer variable waterfall adds a visual and audible element to the experience — a smooth, sheet-like flow of water with integrated lighting. Combined with the multicolour SunRay LED lighting in the footwell and around the water feature, it creates a genuinely atmospheric setting for evening use. The lighting can be set to transition through colours or hold on a single shade.

Water care is handled by the two-stage MicroClean filtration system with a 20-inch Slipstream skimmer, paired with ClearRay Active Oxygen UV-C technology. This keeps the water clean and clear with less chemical use — straightforward day-to-day maintenance.

A practical advantage of the Hamilton is the flexible electrical requirement. It can run on either a 20 Amp or 32 Amp supply, which gives you options depending on your existing electrical setup. Running on 32 Amp will give you faster heating and full pump power simultaneously, but 20 Amp is a viable option if upgrading your supply isn't straightforward.

Power comes from two TheraFlo 2.0 hp jet pumps. The BLUEWAVE spa stereo adds Bluetooth audio, FM radio, JBL speakers. There's also a 780 Series-specific speaker option with waterproof micro-speakers built into the spa near the headrests, an in-spa remote, auxiliary MP3 jack and AM/FM radio.

Shell colours include Platinum, Porcelain, Monaco, Celestite and Midnight. Cabinet options are Modern Hardwood, Brushed Grey and Vintage Oak — a different palette to the 880 Series, with a more natural, textured look.
