Overview: What Is the Sundance Dover Hot Tub?
The Dover hot tub represents Sundance Spa’s answer to a common challenge: how do you bring genuine hydrotherapy into a tight outdoor space without sacrificing the features that make soaking worthwhile? As part of the 780 series, this 2–3 seat compact spa was designed specifically for couples and small households who refuse to compromise on quality just because their patio or small space can’t accommodate a seven-person behemoth.
With its low profile design measuring approximately 31 inches in height, the Dover offers easy entry and exit that larger, deeper tubs simply can’t match. The compact footprint—roughly 69 inches wide by 82 inches long—tucks neatly into narrow side yards, rooftop decks, and townhome patios where a full-size spa would overwhelm the area.
While Sundance officially rates the Dover for three adults, everyday reality tells a different story. This is a spacious, luxury experience for two, with that third seat available when guests visit or children want to join. Think of it as a couples’ retreat that can accommodate company when needed.
Quick Spec Snapshot:
The Sundance 780 Series hot tub seats 2 to 3 adults and measures 69 inches wide by 82 inches long and 31 inches high. It features 23 Fluidix jets and holds between 230 and 315 gallons of water. The dry weight is 620 pounds. Power options include a plug-and-play 120V at 15A or a hard-wired 240V at 30A or 40A. It is equipped with a single 2-speed 1.5 HP pump plus a circulation pump for efficient operation.
Design & Comfort: Compact Size Without Feeling Cramped
The Dover proves that a smaller footprint doesn’t mean feeling squeezed. Its thoughtful layout works remarkably well for townhomes, rooftop decks, and those narrow side yards that seem to exist in every urban property. The low profile shell sits close to the ground, creating visual balance with surrounding landscaping while making the step-in process feel natural rather than athletic.
Seating Layout
The play model features seats arranged to maximize comfort without the awkward knee-bumping that plagues some compact designs:
- SMT Therapy Seat: The series exclusive seat designed for full-body relaxation with spiral action jets targeting shoulders, mid-back, and lumbar regions
- Accu-Pressure Seat: The series exclusive Accu Pressure seat delivers focused deep tissue pressure for targeting stubborn tension points
- Open Third Seat: A more versatile position with rectangle seat jets, practical for guests or children
Ergonomic Touches
Sundance paid attention to the details that matter during a 30-minute soak:
- Three contoured pillows provide head and neck support
- Varied seat depths accommodate users from 5’3” to 6’1” comfortably
- Molded drink holders keep beverages within reach
- LED-lighted footwells add visibility and ambiance
The easy entry and exit the Dover spa provides comes from more than just height. The wide step-in area and textured interior footing benefit older users, those with limited mobility, or anyone who’s ever felt uncertain climbing over a tall spa wall after dark.
Styling remains clean and modern, with cabinet color options that complement both modern hardwood decks and rock walls alike. Once filled and lit at night, this compact shell looks every bit as substantial as larger models—the perfect size for creating a genuine backyard retreat.
Hydrotherapy Performance: Fluidix®, SMT™ & Accu-Pressure™ Seats
Jet counts matter less than how those jets actually feel during daily use. The Dover’s 23 Fluidix jets deliver five distinct massage varieties without the bearings or wearable parts that clog and degrade over time. This means reliable performance year after year, with adjustable flow patterns that mimic kneading, pulsing, and swirling techniques.
The SMT Seat Experience
The series exclusive SMT seat serves as your relaxation lounge. Spiral action jets create a swirling massage melts away fatigue sensation that works systematically across shoulders, mid-back, and lumbar areas. This isn’t aggressive or jarring—it’s the kind of hands on massage sensation that helps you relieve tension accumulated from desk work, yard projects, or simply the weight of daily responsibilities.
The SMT seat feels like skilled hands working across your back in smooth, circular patterns. Many owners settle into this seat first, letting the bold swirling massage melts tension before moving to more targeted therapy.
The Accu-Pressure Seat Experience
When you need to address specific problem areas, the exclusive Accu Pressure seat you’ll find focused deep tissue pressure waiting. This seat targets trigger points in the neck, shoulder blades, and along the spine with pressure to dissolve pain and rejuvenate tired muscles.
After long workdays or physical activity, this seat helps dissolve pain and works through those stubborn knots that resist stretching alone. The find focused deep tissue approach tackles what a general massage cannot, delivering tissue pressure to dissolve pain at its source.
Foot and Calf Relief
The footwell massage deserves special mention. Jets positioned for your feet a bold swirling massage melts fatigue in aching arches and tired calves. Many owners rotate between seats during a 20–30 minute soak, spending time letting the massage melts away muscle fatigue before switching positions to achieve maximum relaxation throughout the entire body.
Practical Use Cases:
- Recovery after running or hiking
- Easing office-related back and neck tension
- Addressing mild stiffness from gardening or home projects
- General muscle pain relief after active weekends
Water Care: CLEARRAY Active Oxygen™ & MicroClean® Filtration
Clean water with minimal fuss ranks among the top priorities for any new hot tub owner, and the Dover delivers with systems designed to reduce chemical dependency while maintaining crystal clarity.
CLEARRAY Active Oxygen System
The CLEARRAY Active Oxygen system uses UV-C light technology to neutralize waterborne pathogens naturally. Think of it as having a secondary sanitation layer working constantly, reducing the amount of chlorine or bromine needed to keep water safe and inviting. This open water management system means less chemical smell, gentler water on skin and hair, and fewer trips to the store for sanitizers.
MicroClean Filtration
The MicroClean system features a 125 square foot cartridge filter with horizontal placement for efficient particle capture. A floating weir helps skim surface debris, while one diverter valve allows you to customize flow direction between seats for personalized massage intensity.
Practical Maintenance Schedule:
For practical maintenance, test strip water checks should be done weekly, and the filter rinsed monthly. Water changes are recommended every 3 to 4 months. The CLEARRAY bulb and filter should both be inspected and replaced annually to keep the hot tub running smoothly.
CLEARRAY On-Demand
After heavy use—weekend guests, a party, or after rain and debris exposure—the push-button CLEARRAY On-Demand cycle provides extra sanitation power. This super-treats your water when circumstances call for it, returning to normal clarity without dramatic chemical intervention.
First-time spa owners can feel confident that the Dover is manageable without a pool-service contract. Visual cues and the auto filter programs help you know when water needs attention, taking the guesswork out of maintenance.
Lighting, Waterfalls & Overall Ambiance
The Dover transforms your outdoor space into a proper retreat, especially after sunset. This isn’t just about soaking—it’s about creating moments of genuine peace in your own backyard.
Exterior Lighting
Stainless steel exterior lights and cabinet corner accents provide subtle, modern illumination that aids visibility on dark patios without feeling like stadium lighting. The exterior indicator light also shows spa status at a glance—helpful when walking past in the evening.
Interior LED Experience
Inside the spa interior, multicolor SunRay LED lighting lets you choose the mood. Switch between steady white for bright visibility, gentle color cycling for relaxation, or settle on a single favorite hue. The illuminated footwells add both safety and atmosphere.
The AquaSheer Waterfall
The AquaSheer waterfall provides gentle sound and visual interest, with backlit LED lighting behind the falling water. On quiet evenings, this feature alone transforms an ordinary soak into something more meditative.
Picture a typical evening: steam rising into cool air, soft LED colors reflecting off the water’s surface, the gentle sound of the waterfall masking neighborhood noise. This is what the Dover offers—maximum relaxation without requiring a resort-sized budget or footprint.
Controls, SmartTub® Connectivity & Daily Use
The Dover was designed for owners who want relaxation without a steep learning curve. Spa functions remain intuitive from day one.
Topside Control Panel
The efficient control panel sits at water level with backlit, weather-resistant buttons for:
- Temperature adjustment
- Jet activation and speed control
- Lighting modes
- CLEARRAY On-Demand cycles
The controls efficient control panel design means you won’t fumble in the dark during early-morning or late-night soaks. Illuminated buttons allow operation without turning on bright house lights, preserving the peaceful atmosphere.
SmartTub System Integration
The optional SmartTub system connects your spa to your mobile device, enabling:
- Temperature control from anywhere
- Scheduling for pre-heating before you arrive home
- Maintenance reminders and alerts
- Energy usage monitoring
- Error notifications (low water, heating issues)
Practical scenarios make this worthwhile: start heating from work so the water’s ready when you pull into the driveway. Lower temperature during vacation to save energy. Receive a notification if something needs attention before a minor issue becomes a major problem.
Most owners get comfortable with basic panel operation within their first two or three soaks. The SmartTub app adds convenience for those who appreciate connected home technology, though it remains optional—the Dover works perfectly without it.
Cabinetry, Exterior Access & Durability
Whether you’re facing harsh summer sun or frigid winter temperatures, the Dover’s exterior holds up to real-world conditions.
UV-Resistant Synthetic Cabinetry
The cabinet panels offer a wood-look aesthetic without the maintenance headaches of actual wood. No staining, no sealing, no worrying about rot or warping. A simple wash with mild soap and water keeps the exterior looking fresh season after season. The UV resistant synthetic cabinetry resists fading even in direct sunlight, maintaining curb appeal for years.
Tool-Free EZ Access
The cabinetry access design allows panel removal without power tools. This matters when servicing pumps, heater, or electronics—you or a technician can get inside quickly without hunting for screwdrivers or risking stripped screws.
Insulation Quality
The shell and cabinet work together to retain heat efficiently. High-density foam insulation throughout the cabinet area reduces heat loss, particularly important for cold-weather operation. This directly impacts your energy bills—less heat escaping means less energy needed to maintain temperature.
Installation, Power Options & Space Requirements
Understanding installation requirements before purchase prevents surprises and delays.
Power Configuration
The Dover is available as a north america convertible model, offering flexibility based on your situation and local electrical regulations:
120V Operation (Plug-and-Play):
- Connects to a dedicated 15-amp household outlet
- Requires GFCI protection (cord supplied)
- Heater limited to 1.0 kW—slower heat recovery
- Simpler installation, no electrician required for basic setup
- Best for mild climates or patient owners
240V Operation (Hardwired):
- Requires licensed electrician for installation
- 4.0 kW heater—significantly faster heating
- Runs jets and heater simultaneously at full power
- Better performance in cold climates
- Higher upfront installation cost
Unlike larger models that require dual power inputs, the Dover keeps electrical needs straightforward with no secondary pump to worry about.
Base Requirements
Your spa needs a solid, level foundation:
- Concrete pad (recommended)
- Reinforced pavers
- Properly engineered deck rated for the filled weight (approximately 3,247 lbs with water)
Plan for at least 18 inches of clearance on the service side for maintenance access, plus enough room around all sides for safe cover lifting.

Access Considerations
Measure your delivery route carefully:
- Gate width (the spa is 69 inches wide)
- Tight corners or stairs
- Obstacles that might require removal
In rare cases—narrow urban lots, rooftop installations—a crane may be needed, which adds to delivery cost.
Typical Timeline:
The typical timeline starts with site preparation for the pad or deck, which takes 1 to 2 days. Electrical work for 240V service usually takes 1 day. Delivery and placement happen on the same day, followed by filling and initial heating that takes 12 to 24 hours. The first soak can usually happen the evening of delivery or the next day.
Energy Use, Operating Costs & Noise
For owners planning nightly or near-daily soaks, energy efficiency directly impacts the long-term value equation.
Monthly Operating Costs
The Dover’s smaller water volume (average fill of 230–315 gallons) requires less energy to heat and maintain than 6–7 person models. Actual costs depend on:
- Local electricity rates
- Climate and outdoor temperatures
- Usage frequency
- Cover quality and fit
- 120V vs. 240V operation
In moderate climates, expect modest monthly costs. Winter operation in cold regions increases consumption, but the Dover’s insulation and compact size keep bills manageable compared to larger spas.
Energy-Saving Features
Several design elements work together to reduce operating costs:
- High-density insulation throughout
- Well-fitted spa cover (essential—always purchase quality)
- Smaller water volume heats faster, loses less
- SmartTub energy monitoring helps identify optimization opportunities
- Single pump design uses less power than multi-pump systems
Noise Levels
The circulation pump runs quietly during filtration cycles—barely noticeable from inside your home. Jets at high speed produce moderate noise typical of any spa, but nothing excessive. Tips for minimizing perceived sound:
- Keep the cover closed during heating cycles
- Position the spa away from bedroom windows
- Consider landscaping or fencing as sound buffers
How the Dover Compares to Other Sundance Models
Sundance shoppers often weigh the Dover against the Montclair and other dover 780 series options before deciding.
Dover vs. Montclair Comparison
The Dover seats 2 to 3 adults with compact dimensions of 69 by 82 by 31 inches and features 23 jets, making it ideal for couples or small spaces. In contrast, the Montclair is mid-size, seating 4 to 5 adults in a larger footprint of 75 by 91 by 33.5 inches, equipped with over 30 jets, and designed for families or entertaining guests.
When to Choose Dover
The Dover fits best when:
- Your patio or small space can’t accommodate larger models
- Primary use is couple-focused relaxation
- Easy entry matters (lower profile)
- You want premium features without the larger footprint
- Budget-conscious on operating costs
When to Consider Montclair
The Montclair makes more sense when:
- You regularly host 4+ guests

FAQ
Does the Sundance Dover really fit three adults comfortably?
The Dover is rated for up to three adults, but in everyday use, it feels most luxurious for two. That third seat works well for occasional guests, children joining parents for a soak, or rotating positions during longer sessions. Three large adults every night would feel snug—this spa truly shines as a couples’ retreat with flexibility for company.
Can I run the Dover on a standard household outlet, or do I need 240V power?
Many Dover units are configured for 120V plug and play model operation, which simplifies installation significantly. However, the 1.0 kW heater at 120V heats water slowly, especially in cold weather. Converting to 240V with a licensed electrician provides a 4.0 kW heater, dramatically improving heating speed and cold-weather performance. For mild climates and patient owners, 120V works fine. For cold regions or those wanting quick heat recovery, 240V proves worthwhile.
How often will I need to change the water and filters in a Dover hot tub?
Most owners change water every 3–4 months with normal use (two people soaking several times weekly). Rinse filters monthly to remove accumulated debris, and replace filter cartridges roughly once a year. Usage patterns, bather load, and local water quality can shift this schedule—heavy use or hard water may require more frequent attention.
Is the Sundance Dover a good choice for cold-weather climates?
Yes, with proper setup. The Dover’s insulation, quality spa cover, and smaller water volume make it suitable for cold-weather use. Key requirements include installation on a proper level base, correct electrical wiring (240V recommended for faster heating), and keeping the cover securely in place when not soaking. Many owners in northern climates use their Dover year-round without issues.
What accessories should I budget for when buying a Dover?
Common add-ons to consider include matching steps for entry, a cover lifter for easy cover removal, spare filters, a water care starter kit, and the optional SmartTub module for app connectivity. Ask your dealer which accessories come bundled versus priced separately—negotiating a package deal often saves money compared to purchasing items individually later.
