An outdoor swim spa is one of the more demanding line items in a villa or resort package. It arrives as a shell, a pump room, an electrical load and a set of site conditions that all have to agree before the first litre is filled. The Outdoor Swim Spa WS-130CⅢ sits at the long end of our configurable range, and buyers comparing it against other models or other suppliers usually find that the interesting differences are not in the brochure photos but in how the specification is documented. The comparison below follows the order we recommend for any swim spa enquiry: footprint first, then equipment, then what sits outside the standard scope.

Start with the footprint, because it decides everything else

Catalog dimensions for this model are 11830 × 3000 × 1430 mm (length × width × height). That length is what puts the unit in a different planning conversation from a compact spa. A swim channel of that scale needs a deck or slab run long enough to carry it, clear access for delivery and crane or forklift placement, and a visual relationship with the rest of the outdoor area rather than a corner position.

Before comparing prices, ask each supplier for three drawings: overall dimensions including any external steps or cabinet cladding, a plan view showing where the control system and pumps sit, and an access route from the delivery vehicle to the final position. Two units listed at the same length can differ by several hundred millimetres once steps, plant recesses and cladding are included, and that difference is what turns a site preparation budget into a variation order.

Read the equipment list as a set of line items, not a feature paragraph

The WS-130CⅢ product page lists its specification item by item. That format is worth insisting on from any supplier, because "with jets and lighting" means nothing when you are trying to establish whether two quotations describe the same machine.

Three of those lines deserve more attention than they usually get. The swim training system is what distinguishes a swim spa from an oversized spa; it generates the current you swim against, and its output determines whether the unit is realistic for daily lap training or only for short sessions. Confirm the type of current generation and request a video of the system running in the finished shell. The total power figure of 10.85 kW is an electrical planning input, not a marketing number: it drives cable sizing, protection devices and whether your electrician needs to upgrade a distribution board before installation. And the split between water pump and filter pump matters because jet performance and filtration runtime are controlled separately; a single combined pump lowers cost but limits how you run the machine day to day.

Compare what is excluded as carefully as what is included

Most price gaps between swim spa quotations come from scope boundaries rather than hardware quality. For a project of this size, put the following in writing with every supplier you are evaluating:

• Heating. A heat pump is an option on many configurations, not an automatic inclusion. Without it stated on your quotation, compare prices on a cold-shell basis and add the heating solution separately.
• Water treatment. Ozone is shown as a feature on this model; UV sterilisation and sand filtration are listed as options elsewhere in the range. Decide which combination your site conditions call for, then price that combination consistently across suppliers.
• Insulation and cladding. Insulation level changes running cost in cooler climates, and cabinet cladding is what makes the unit read as a finished outdoor element rather than a tank. Specify both.
• Steps, access and foundations. Steps are an option on this range; the slab, deck or plinth underneath the unit is normally local work. Confirm which party supplies each.
• Electrical supply and controls location. Where the control system sits relative to the cabinet affects both installation cost and how usable the panel is in wet weather.

Check the model variant before you compare two quotations

Our catalogue lists closely related variants side by side, and a single letter changes what arrives on site. The Outdoor Swim Spa WS-130CⅢ-U carries the same catalog dimensions of 11830 × 3000 × 1430 mm but is listed with water jets, LED lighting and ozone — without the swim training system shown on the WS-130CⅢ. Shorter options in the same family, such as the Outdoor Swim Spa WS-130AⅢ at 8000 × 3000 × 1400 mm and the Outdoor Swim Spa WS-130BⅢ at 9950 × 3000 × 1430 mm, cover the same width and height with a shorter swim channel, which is often the right answer when the terrace run is limited. If two quotations differ sharply in price, check the model code character by character before assuming one supplier is cheaper.

Where customisation genuinely helps

Standard sizes work well when the outdoor area can be designed around them. They stop working when a spa has to fit an existing terrace edge, a curved pool surround or a set-back boundary. For those cases we produce customizable shape outdoor spas in square, round, oval and curved layouts, with an acrylic shell and structural reinforcement built to the space rather than to a catalogue length. The whole swim spa family is listed under Swimming Pools and Swim Spas, so you can see how a standard model relates to the rest of the range before deciding whether customisation is needed at all.

The questions worth putting in your enquiry

Which items are in the quoted price and which are options?

Ask for the quotation as a bill of quantities: shell, control system, pumps, jets, lighting, ozone, swim training system, heat pump, insulation, steps, cladding. Anything not itemised is either included somewhere you have not seen or extra later.

What do I need to prepare on site?

Request the dimensioned plan, the electrical load figure and the delivery access notes early enough that your civil and electrical trades can price from them. For an 11830 mm unit, access and craneage are usually the first constraint you hit.

Can the specification be changed after order?

Changes to jet count, lighting or treatment options are straightforward before production starts and expensive afterwards. Lock the configuration at the detail-confirmation stage, which is also when drawings and material finishes should be signed off.

How does the swim spa fit into a wider project package?

A swim spa rarely arrives alone in a villa or resort project — it usually travels with outdoor furniture, pergolas, bathroom ceramics and wall or ceiling finishes. Consolidating those lines with one logistics and door-to-door delivery arrangement reduces the number of consignments to clear and coordinate; our project services cover design coordination, production follow-up and installation support across that package. Start a conversation through our contact page with your site drawings, and we will confirm the configuration, included equipment and electrical requirements for the exact unit you are specifying.
