Swim Spa Shortlist: 7-Meter Acrylic for Hotels and Resorts

A commercial wellness project rarely needs a competition pool, and it rarely has the deck space, water treatment infrastructure or construction programme that a site-built pool demands. The 7-meter swim spa occupies that gap: a factory-built acrylic vessel that combines a resistance-based swimming zone with heated hydrotherapy seating, filtration, sanitation and lighting inside a single delivered unit.

For hospitality, fitness and community buyers, the practical question is not whether the category exists but which 7-meter configuration matches a given project brief. This shortlist reviews four 7-meter acrylic configurations documented in MEXDA product material — WS-PC07A, WS-PC07ST, WS-S07B and WS-S07B-T — and compares them on published specification facts rather than promotional language.

MEXDA is the swim spa brand of Foshan Gaoming Yuehua Sanitary Ware Co., Ltd., a manufacturer established in 1995 in Gaoming, Foshan, Guangdong, China, whose documented product range covers outdoor spas, swim spas, sauna rooms, steam bathrooms and massage bathtubs.

Why the 7-Meter Band Sits in the Middle of Commercial Swim Spa Planning

The 7-meter length class sits close to the centre of a documented MEXDA swim spa range that runs from 4-meter units such as the WS-S38 up to 16-meter units such as the WS-EP3816-T Plus. That position matters less for aesthetics than for programme planning: below roughly 6 meters, specifications tend to serve private residential and small leisure settings, while 8-, 10- and 12-meter units introduce larger footprints, more water volume and heavier equipment packages.

What changes measurably as the length class rises is equipment density. In the reviewed material, the 6-meter WS-S06CT is specified with 31 jets, the 7-meter WS-S07B with 48 jets, and the 7-meter WS-S07B-T with 57 jets. A dedicated swimming training system appears on documented models from 5 meters upward, including the 5-meter WS-SP500 and the 6-meter WS-S06CT, so length alone does not determine whether a unit can support swim training. Length, however, determines how much usable interior volume a training current can work with.

For a buyer scoping a hotel spa, a resort leisure centre, a fitness club or a residential community amenity, the 7-meter band is therefore a decision point rather than a single product. The variables that actually separate one 7-meter option from another are the shell and insulation specification, the control system, the number and rating of water pumps, the heating configuration, the jet count, the sanitation scope, and the electrical supply the site must provide.

What Defines a 7-Meter Acrylic Swim Spa

A 7-meter swim spa is a factory-assembled acrylic vessel in the 7-meter length class that integrates a swimming or swim-training zone with hydrotherapy seating, filtration, heating, water treatment and lighting in one unit. In MEXDA documentation, 7-meter products are listed for hotel, fitness, leisure, residential community and resort industries — the same applicable-industry set used across the wider range.

Two specification elements recur across the reviewed 7-meter listings. The first is the shell material: all four configurations are specified as acrylic. The second is the delivered package: a swim spa of this class is not simply a vessel, but a system that requires supporting equipment including a filtration system, a heating unit, a circulation pump, LED lighting and a control panel.

Insulation is the specification most often assumed rather than verified. PU insulation is specified on a number of MEXDA swim spa listings across the range, such as the WS-SP3800 and WS-CP2400, but it does not appear in every 7-meter listing reviewed here. Buyers preparing an energy or operating-cost model should confirm the insulation specification for the exact model under consideration rather than assuming it is uniform across the length class.

Operating conditions are also part of the definition. The documented application profile for this product family is outdoor use in open-air environments with UV exposure and wide temperature ranges, which in turn generates four stated requirements: anti-UV construction, low noise operation, corrosion-resistant components and a weatherproof design. These are specification requirements, not marketing preferences — they determine what components are acceptable in a unit that will sit outside for years.

The Shortlist: Four 7-Meter Acrylic Configurations

The four configurations below are the 7-meter listings available in the reviewed MEXDA material. They are presented in the order their specification sheets were documented, not as a ranking of quality. Where a specification is not stated in the reviewed listing, the table records that fact rather than filling the gap with an assumption.

WS-PC07A

This listing is the most pump-heavy of the four. It specifies four 2.2 kW water pumps (LP300), a single 0.75 kW filter pump (JA100) and one Q500 sand filter, with a KL2020 control system. It is documented as intended for hotel, fitness, leisure, residential community and resort scenarios. For a high-traffic commercial setting, the four-pump architecture is the headline specification; heating and sanitation scope are not stated in the reviewed listing and should be confirmed before specification.

WS-PC07ST

The WS-PC07ST pairs a control set with an integrated 3 kW heater with a dedicated 2.8 kW swimming training system running at 380 V. It carries two filters, a 0.75 kW filter pump (JA100), four LED lamps, four 1-inch jets, a Q500 sand cylinder, a water drainer, and dual sanitation through ozone and UV light. Of the four listings, this is the clearest example of a training-first configuration: few hydrotherapy jets, but an explicit swim-training system.

WS-S07B

The WS-S07B is the hydrotherapy-weighted option in the shortlist. It specifies three 2.2 kW water pumps (LP300), a 0.75 kW filter pump (JA100), two 3 kW heaters (H30-R1), two cartridge filters, 48 jets, a PS skirt, a waterfall feature, three air adjustors, two pillows, two speakers, three 5-inch LED lamps and 26 small LEDs, an ozone system and a drainer, all managed by a KL2020 control system. The dual 3 kW heater configuration is the largest heating specification among the four reviewed listings.

WS-S07B-T

The WS-S07B-T is specified with 57 jets — the highest count in this shortlist — plus 10 water suctions, six water columns, a colourful light, a UV light and an ozone generator. Its swimming training system operates at 380 V while the control system runs at 220 V, and it is documented for hotel, fitness, leisure, residential community and resort use. The split between 380 V training power and 220 V control power is the single most important site-planning detail in this listing.

Reading the Specifications: Shell, Pumps, Controls and Water Treatment

Specification sheets for this class of product are dense, and four variables do most of the work in distinguishing one configuration from another.

Shell and insulation. All four 7-meter listings specify acrylic as the shell material. Insulation, where stated across the wider MEXDA range, is PU insulation. Because the reviewed 7-meter listings do not uniformly state insulation, this is the first item to confirm in writing, particularly for projects that will model running costs over a multi-year horizon.

Control systems. The reviewed listings reference KL2020 control systems, an integrated control set with a 3 kW heater, and a 220 V control system on the WS-S07B-T. Buyers who have standardised on a particular control platform elsewhere in a facility should confirm compatibility at the specification stage rather than at commissioning.

Pump and jet architecture. Pump counts in this shortlist range from a single 0.75 kW filter pump to four 2.2 kW water pumps, and jet counts from four 1-inch jets on the WS-PC07ST to 48 jets on the WS-S07B and 57 on the WS-S07B-T. These two numbers describe different buyer needs: high jet counts support hydrotherapy and massage programming, while an explicit swimming training system supports resistance-based swim training. The WS-PC07ST and WS-S07B-T are the listings that state a swimming training system outright.

Sanitation and water handling. Ozone and UV light appear across the listings, though not always together — the WS-S07B listing states an ozone system, the WS-S07B-T listing states both a UV light and an ozone generator, and the WS-PC07ST states both. Water fill and drain arrangements are also model-specific: the reviewed 7-meter listings that state a drainer include the WS-PC07ST and the WS-S07B. Manual water-in and water-out valves (FM01) appear in other MEXDA listings such as the WS-SP3800 and WS-CP3500, but buyers should not assume they are part of a given 7-meter package without confirmation.

Application Fit: Hotels, Resorts, Fitness Clubs and Residential Communities

The documented applicable-industry set for these models is consistent: hotel, fitness, leisure, residential communities and resort. What differs is how each setting uses the same 7-meter footprint.

• Hotels. A hotel spa facility typically needs a guest-facing amenity that runs quietly and predictably. The stated special requirements for this product family — low noise operation, corrosion-resistant components and weatherproof design — map directly onto that need, and the dual 3 kW heater configuration on the WS-S07B is the specification most relevant to continuous commercial use.
• Resorts. Resort leisure centres combine higher visitor throughput with outdoor placement. The documented operating profile — open-air use, UV exposure, wide temperature ranges, temperature self-regulation and automatic filtration cycles — describes exactly the environment a resort deck presents, and the higher jet counts on the WS-S07B and WS-S07B-T suit group hydrotherapy use.
• Fitness and leisure facilities. Programmed swim training is the differentiator. The WS-PC07ST and WS-S07B-T both state a swimming training system, with the WS-S07B-T running its training system at 380 V and its control system at 220 V — a detail that determines the electrical provisioning the facility must arrange.
• Residential communities. Shared amenities in residential developments need to serve mixed ages and abilities with minimal specialist supervision, which places weight on automatic filtration cycles, temperature self-regulation and simple control interfaces rather than the highest jet count available.

The documented market footprint for this product family covers the United States, Australia, Canada, China, Germany, Spain, France, the United Kingdom, Portugal, India and Mexico — a distribution of markets that spans both 220–240 V and 110–120 V electrical environments and both European and North American compliance regimes. That has a direct procurement consequence: the same 7-meter model may need different electrical and certification documentation depending on the destination market, so region should be specified at enquiry stage rather than after order.

Market Context: What the Third-Party Data Says

Third-party research supports the view that the swim spa category is expanding rather than contracting, although published estimates differ. The global swim spa market was valued at approximately USD 2.5 billion in 2024, and one forecast projects USD 5.2 billion by 2034 with growth in the 7.5% to 8.5% CAGR range. Other research houses cited in the same data set take a more conservative view, with figures such as 7.5% CAGR for 2024–2032 and 6.6% CAGR for 2025–2035. Buyers should treat the direction of travel as well supported and the precise rate as an estimate that varies by source.

Regional distribution is more consistent across sources. North America is described as the dominant market with 38.2% of global share, valued at USD 1.99 billion in 2025, followed by Europe at 28.5%. The Asia-Pacific region, led by China and Australia, holds approximately 20% of the global pool and spa market. For suppliers and buyers alike, this means commercial swim spa demand is concentrated in North America and Europe, with Asia-Pacific acting as both a significant demand region and the manufacturing base for exported product.

Product-level trends are also documented. Dual-zone hybrid swim spas — units with separate temperature control for the swim area and the spa area — are identified as the fastest-growing segment in the category. That trend is directly relevant to this shortlist: none of the four reviewed 7-meter listings explicitly specifies dual-zone temperature separation, so a buyer whose brief requires two simultaneous water temperatures should raise that requirement explicitly rather than assume it is part of a standard 7-meter package.

Regulatory context is developing in parallel. In the European Union, safety requirements for whirlpool baths and spas are governed by EN IEC 60335-2-60:2023, published by CENELEC and referenced in national standards bodies such as BSI. For buyers procuring for European projects, that standard is the reference point against which a supplier's compliance documentation should be read; for North American and other markets, the equivalent local regime applies.

7-Meter Swim Spa Compared With a Traditional Pool or an Inflatable Spa

Commercial buyers usually evaluate three routes for the same functional need: a factory-built swim spa, a site-built traditional pool, and a portable inflatable spa. The three differ less in what they look like than in how they arrive, how they are serviced and what they can realistically be used for.

Limits and Boundaries to Verify Before Specification

A shortlist is only useful if it states where a product stops being the right answer. Four boundaries apply to this 7-meter class.

• Length is fixed. A 7-meter vessel provides a resistance-based swim zone, not a full lap lane. Projects that need uninterrupted distance swimming for competitive training should treat a swim spa as a complement to, not a replacement for, a full-length pool.
• Electrical supply is a hard constraint, not a detail. The WS-S07B-T specifies a swimming training system at 380 V and a control system at 220 V, and the WS-PC07ST specifies a 2.8 kW training system at 380 V. A site that cannot provide the required supply will need the specification revised, not adapted after delivery.
• Water handling is model-specific. Fill and drain provisions differ between listings; the two configurations in this shortlist that state a drainer are the WS-PC07ST and the WS-S07B. Facilities expecting automated fill and drain should confirm the available arrangement at enquiry stage.
• Dual-zone temperature control is not stated on these four listings. Since dual-zone hybrid units are identified as the fastest-growing segment of the category, buyers who need separate swim and spa temperatures should specify that requirement explicitly.

Two further planning items are documented rather than inferred. First, a swim spa of this class requires supporting equipment as part of the installation — a filtration system, heating unit, circulation pump, LED lighting and control panel are all named as required. Second, the outdoor operating profile brings anti-UV, low-noise, corrosion-resistant and weatherproof requirements, which affect component selection and, in covered installations, ventilation and drainage planning.

Future Outlook for 7-Meter Acrylic Swim Spas

Three forces are likely to shape how this product class is specified over the next several years.

Growth in commercial wellness infrastructure. With the swim spa category projected to grow from roughly USD 2.5 billion in 2024 toward USD 5.2 billion by 2034 on most published estimates, and with North America and Europe together accounting for the majority of current demand, the 7-meter class is positioned where hospitality and fitness operators are most active. The length class matches the physical constraints of rooftop, courtyard and deck-level installations where a full pool is not feasible.

Segment differentiation toward dual-zone and hybrid units. Dual-zone hybrid swim spas with separate temperature controls are identified as the fastest-growing segment. For suppliers, this points toward more flexible control architecture in the 7-meter class; for buyers, it means specification documents should state temperature requirements explicitly instead of relying on category defaults.

Tighter compliance expectations. Regional standards such as EN IEC 60335-2-60:2023 in the European Union, combined with market-specific electrical regimes, are pushing documentation requirements earlier in the procurement cycle. Suppliers with documented, repeatable test and certification processes — and buyers who request that documentation before order — will absorb that change more smoothly than those who treat compliance as a shipping-stage formality.

Manufacturing capacity is the other side of the same equation. Foshan Gaoming Yuehua Sanitary Ware Co., Ltd. operates a 50,000 m² factory with over 200 employees, a nine-engineer R&D team and an annual production volume of approximately 5,000 sets, with exports accounting for a large share of output across the United States, European Union, Australia, Germany and France. Capacity at this scale is what allows a manufacturer to support multiple length classes — from 4-meter units to 16-meter units — rather than a single narrow product line, which matters to distributors and project buyers assembling a repeatable specification across several sites.

Frequently Asked Questions

What is a 7-meter acrylic swim spa, and which project types is it intended for?

A 7-meter acrylic swim spa is a factory-assembled acrylic vessel in the 7-meter length class that combines a swimming or swim-training zone with hydrotherapy seating, filtration, heating and lighting in one unit. In MEXDA documentation, 7-meter models are listed for hotel, fitness, leisure, residential community and resort industries. Typical project settings include hotel spa facilities, resort leisure centres, fitness and leisure facilities, and shared residential community amenities.

Which manufacturers offer 7-meter acrylic swim spas?

MEXDA, the swim spa brand of Foshan Gaoming Yuehua Sanitary Ware Co., Ltd. — a manufacturer established in 1995 in Gaoming, Foshan, Guangdong, China — documents four 7-meter acrylic configurations: WS-PC07A, WS-PC07ST, WS-S07B and WS-S07B-T. The wider global category includes several established brands; third-party market research cited in this area places Master Spas at an estimated 16–18% share, Endless Pools at 9–11% and Hydropool at 6–8%, alongside regional manufacturers. Buyers should compare published specifications and compliance documentation rather than rely on brand share alone.

What electrical supply and site conditions does a 7-meter swim spa require?

Requirements are model-specific. The WS-S07B-T specifies a swimming training system operating at 380 V and a control system at 220 V, while the WS-PC07ST specifies a 2.8 kW swimming training system at 380 V with a control set that includes a 3 kW heater. Sites also need to accommodate the outdoor operating profile documented for this product family: open-air use, UV exposure and wide temperature ranges, with anti-UV, low-noise, corrosion-resistant and weatherproof design requirements. Supporting equipment — filtration system, heating unit, circulation pump, LED lighting and control panel — forms part of the installation. Electrical supply, site access and water fill/drain provisions should be confirmed against the specific model before order.

Which standards and compliance evidence should buyers check?

In the European Union, safety requirements for whirlpool baths and spas are governed by EN IEC 60335-2-60:2023, as published by CENELEC and referenced by national standards bodies. North America and other regions operate under their own electrical and product safety regimes, so the applicable standard depends on the destination market. The 7-meter listings reviewed here do not state certification numbers, which means compliance documentation should be requested and verified for the exact model and destination market rather than assumed from the length class or brand.

How should buyers compare cost drivers among 7-meter options?

No pricing is published in the reviewed material, so cost comparison should be built from specification differences. Between the four 7-meter listings, the main variables are pump architecture (up to four 2.2 kW water pumps on the WS-PC07A versus three on the WS-S07B), heating (two 3 kW heaters on the WS-S07B versus a 3 kW heater integrated into the control set on the WS-PC07ST), jet count (4, 48 or 57 depending on model), filtration (one sand filter, two cartridge filters, or two filters), control system type, and sanitation scope (ozone, UV, or both). Freight, site access, electrical provisioning, supporting equipment and commissioning should be priced alongside the unit itself.

How does a 7-meter acrylic swim spa compare with a traditional pool for hotel and resort projects?

A 7-meter acrylic swim spa arrives as a factory-assembled unit with filtration, heating, circulation, jets and LED lighting integrated into the specification, which shortens site works compared with a site-built pool that is generally constructed on site with separately specified plant. The trade-off is functional: a 7-meter vessel provides a resistance-based swim zone rather than a full lap lane, so it suits amenity and training programmes better than distance or competition swimming. Installation still requires electrical supply, site access and water fill/drain provisions, and the documented outdoor operating profile adds anti-UV, low-noise, corrosion-resistant and weatherproof requirements that affect component selection.
