Marquis Spas is an Oregon-based manufacturer, close enough to the Pacific Northwest that a lot of BC buyers end up comparing the two directly. It is a US-built acrylic spa with a solid dealer network and a wide range of cabinet styles and jet configurations. Given the geography, it deserves a fair, spec-based comparison rather than a quick dismissal.
The short version: Marquis builds a traditional acrylic spa with a foam-core cover and a broad catalogue of shapes and finishes. Eco Spa builds a single-piece HDPE shell with a rigid hard cover, aimed at the lowest lifetime cost and the least ongoing maintenance. Here is the honest, section-by-section breakdown.
Shell: Acrylic vs One-Piece HDPE
Marquis, like most premium acrylic manufacturers, forms an acrylic shell over a mould, bonds it to a backing, and mounts it in a supporting frame. That process can produce a genuinely handsome finish, with a good range of colours and cabinet options. The trade-off is structural: an acrylic shell is a layered assembly, and BC's freeze-thaw and heat cycling work on those bond lines over years of use. Acrylic's surface is also porous at a microscopic level, which can give bacteria a place to take hold over time.
Eco Spa forms the entire shell from a single piece of HDPE, a non-porous material with no bonded layers and no seams. The look is more industrial and offers fewer colour choices than acrylic, but there is nothing underneath it to delaminate, and the shell carries a lifetime warranty.
The Cover: Foam vs Rigid Hard Cover
Marquis ships a foam-core cover, standard across nearly the entire acrylic spa industry. In a rainy climate like BC's, foam-core covers gradually absorb moisture, get heavier, and lose R-value, which is why they typically get replaced every three to six years. That is where a lot of the real ten-year cost difference sits; see hard cover vs foam cover for the full math.
Eco Spa's hard cover is a rigid, R-40 lid with a 350 lb load rating. It cannot absorb water, and it is warrantied for life, so there is no cover replacement cost to plan for.
Insulation & Running Cost
Marquis insulates the cabinet in the way most acrylic spas in its class do, which is efficient while the spa and its cover are still new. Eco Spa combines an R-30 insulation wrap with the R-40 hard cover and an air-chambered base. Because roughly 70% of a hot tub's heat loss happens through the top, that hard cover does an outsized share of the work on the Eco Spa side.
In BC, that setup typically runs an Eco Spa at $10 to $40 a month in electricity, depending on the season and voltage. Both brands are efficient when new; the gap tends to open once a foam cover has spent a few winters in the Pacific Northwest's rain.
Water Care
Marquis's factory water care follows the routines common across the acrylic spa category, typically chlorine or bromine with manual or semi-automated dosing. 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 runs a few minutes a month, set up as a personal maintenance template at delivery.
Installation
Marquis's larger, multi-pump models generally need a hardwired 220V circuit and an electrician, along with a level 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 choose and no concrete pad, electrician or plumber required. Details are on the installation page.
Warranty & Price
Marquis backs its spas with the manufacturer's warranty typical of its lineup; the exact terms are best confirmed directly with a Marquis dealer. Eco Spa backs both 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 case for it is built around total ownership cost over a decade rather than the lowest number at delivery.
Which One Is Right for You?
If cabinet and shape variety, a wide range of jet configurations, an established dealer network close to home, and dealer financing matter most, Marquis is a legitimate, well-built option. If your priorities are the lowest lifetime cost, the least hands-on maintenance, and a shell and cover you won't need to replace, Eco Spa is built specifically around that. Both are good hot tubs, they are just built for different buyers.
The clearest way to decide is to see the HDPE shell and lift the hard cover yourself. Visit a BC showroom or request a quote.
Frequently Asked Questions
Is Marquis a good hot tub brand?
Marquis Spas is an Oregon-based acrylic spa manufacturer, close enough to BC that plenty of buyers cross-shop the two. It has a solid dealer network and a wide range of cabinet and jet configurations. It is a traditional acrylic spa, so it shares the trade-offs common to that style of construction, mainly a foam cover and a shell surface more prone to wear over many years.
What is the main difference between Eco Spa and Marquis?
Structure. Marquis builds a vacuum-formed acrylic shell on a supporting frame with a foam-core cover, the standard approach across most of the acrylic spa industry. Eco Spa builds a single-piece HDPE shell with a rigid, lifetime hard cover. The difference shows up in what a tub costs to own over ten years, not in the price on day one.
Does Eco Spa cost less than Marquis to own over time?
Eco Spa is designed around lifetime cost: no cover replacements, a BC running cost of roughly $10 to $40 a month, and minimal chemical use. Marquis runs efficiently when new, so the gap tends to widen over the years as a foam cover degrades 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, Marquis included, typically need a dedicated 220V circuit.
Is Ecozone included on every Eco Spa?
It is an upgrade on most Eco Spa models and standard on the Deluxe models. You still carry a small sanitizer residual either way; what changes is how much of the oxidizing work the ozone handles for you.
