Sundance Spas is a Jacuzzi Brands company, part of one of the larger ownership groups in the hot tub industry. It is a US-built acrylic spa with decades behind it, a sizeable dealer network, and a broad range of seating layouts and jet configurations to choose from. It is a common cross-shop for BC buyers, so it is worth an honest, spec-based look rather than a quick dismissal on price.
The short version: Sundance builds a well-established acrylic spa with a foam-core cover and the seating and financing options that come from a large manufacturer. Eco Spa takes a different structural route, a one-piece HDPE shell and a rigid hard cover, built around the lowest cost of ownership rather than the widest catalogue. Here is how the two actually compare.
Shell: Acrylic vs One-Piece HDPE
Sundance builds its shells the way most premium acrylic manufacturers do: acrylic sheet formed over a mould, bonded to a backing, and set into a supporting frame. That process is capable of a genuinely attractive finish, with a wide choice of colours and a polished cabinet fit. The trade-off is structural: an acrylic shell is an assembly of different materials, and years of BC's heat cycling work on the seams between them. Acrylic's surface is also porous at a microscopic level, which gives bacteria somewhere to take hold over time.
Eco Spa forms the whole shell from one piece of HDPE, a non-porous material with no bonded layers and no frame to separate from the shell. The look is more industrial, with fewer colour options than acrylic offers, but there is nothing to delaminate, and the shell is backed by a lifetime warranty.
The Cover: Foam vs Rigid Hard Cover
Sundance ships a foam-core cover, standard across nearly the whole acrylic spa industry. In BC's wet climate, foam-core covers gradually take on moisture, get heavier, and lose insulating value, which is why they typically get replaced every three to six years. That single line item is where a lot of the ten-year cost gap actually lives; see hard cover vs foam cover for the numbers.
Eco Spa's hard cover is a rigid, R-40 lid rated to hold 350 lbs. It cannot absorb water, and it is warrantied for life, so there is no replacement cost to plan for down the road.
Insulation & Running Cost
Sundance insulates the cabinet the way most premium acrylic spas do, which is genuinely effective while the spa and its cover are new. Eco Spa layers an R-30 insulation wrap with the R-40 hard cover on top and an air-chambered base underneath. About 70% of a hot tub's heat loss happens through the top, so the hard cover is doing a disproportionate amount of the work on the Eco Spa side.
In BC, that combination typically runs an Eco Spa at $10 to $40 a month in electricity, depending on the season and whether it is wired 110V or 220V. Both brands run efficiently when new; the difference compounds once a foam cover has been through a few wet Island winters.
Water Care
Sundance's factory water care follows the routines common to the acrylic spa category, generally chlorine or bromine with manual or semi-automated dosing, and ozone or salt-based add-ons on some configurations. Eco Spa uses the Ecozone ozone system, which oxidizes contaminants roughly 3,000 times faster than chlorine. It is an upgrade on most Eco Spa models and standard on the Deluxe models. Both approaches still rely on a small sanitizer residual; the Ecozone routine typically takes a few minutes a month, built around a personal maintenance template set up at delivery.
Installation
Sundance's larger, multi-pump models generally need a hardwired 220V circuit and an electrician, along with a solid concrete pad or reinforced deck. Every Eco Spa is convertible on every model: plug into a standard 110V outlet, or hardwire 220V for faster heating, with no separate configuration to pick and no concrete pad, electrician or plumber required. More detail is on the installation page.
Warranty & Price
Sundance's warranties follow the terms typical of a Jacuzzi Brands spa; the specifics are best confirmed with a Sundance dealer directly. Eco Spa backs the shell and the hard cover with a lifetime warranty, not prorated, plus two years of coverage on mechanical components. Pricing starts at $11,999 CAD, and the value argument is built on total ownership cost across a decade rather than the sticker on delivery day.
Which One Is Right for You?
If a large dealer network, deep seating and jet variety, brand recognition, and dealer financing matter most to you, Sundance is a strong, established option. If your priority is the lowest lifetime cost, the least hands-on maintenance, and a shell and cover that won't need replacing, Eco Spa is built specifically for that. Both brands are solid, they are just optimized for different buyers.
The clearest way to compare them is in person: touch the shell, lift the cover. Visit a BC showroom or request a quote.
Frequently Asked Questions
Is Sundance a good hot tub brand?
Sundance Spas, a Jacuzzi Brands company, is a US-built acrylic spa manufacturer with a long history, a large dealer network and a wide range of seating and jet configurations. It is a traditional acrylic spa, so it carries the trade-offs common to that construction, mainly a foam cover and a shell that is more sensitive to years of heat cycling.
What is the main difference between Eco Spa and Sundance?
Structure. Sundance builds an acrylic shell on a supporting frame with a foam-core cover, the layout most of the industry uses. Eco Spa builds the entire shell from a single piece of HDPE with a rigid, lifetime hard cover. The gap shows up in what a tub costs to own over ten years rather than on the price tag at delivery.
Does Eco Spa cost less than Sundance to own over time?
Eco Spa is built around lifetime cost: no cover replacements, a BC running cost of roughly $10 to $40 a month, and minimal chemical use. Sundance's efficiency is solid when the spa is new, so the difference tends to grow in later years as a foam cover waterlogs and consumable parts cycle through.
Can an Eco Spa run on a regular household outlet?
Yes. Every Eco Spa is convertible: it runs on a standard 110V outlet with no electrician, or you can hardwire 220V for faster heating. Larger, multi-pump acrylic spas from most brands, Sundance included, typically need a dedicated 220V circuit and an electrician.
Does Eco Spa use ozone water care like some Sundance models?
Eco Spa's Ecozone ozone system is an upgrade on most models and standard on the Deluxe models. Ozone and salt-based add-ons show up across the acrylic spa category too, including some Sundance configurations. Either way, a small sanitizer residual is still part of the routine.
