A seven-metre swim spa is a serious line item in a villa or resort landscape package, and the difference between a good purchase and an expensive regret usually comes down to what was confirmed before the order was placed. This guide walks through the decisions that matter for Outdoor Swim Spa WS-S07B, using the catalogue data published on our product page as the reference point and showing how the same checks apply across the wider range.
Start with the footprint, not the finish
The catalogue lists WS-S07B at 7000 × 2200 × 1335 mm. Before anything else, put those numbers onto your site drawing. A 7 m shell needs clear access for delivery and lifting, a slab or plinth designed for the loaded weight of a full basin, and room around the perimeter for the plant and for maintenance access. The 1335 mm shell height also sets the relationship between the waterline and the surrounding deck level — a decision that affects steps, seating edges and how children and older guests enter the water.
Two practical checks at this stage: confirm the plant location relative to the shell, and confirm who is responsible for the base, the power feed and the waterproofing interface. On project work these three items are where swim spa budgets quietly grow.
Read the specification as a configuration, not a fixed list
The published specification for WS-S07B records one control system, three water pumps, one filter pump, a jet total of 48 pieces, LED lighting (three main lights plus 26 small LED lights), and a listed total power of 13.35 kW. The features shown on the page are water jets, LED lighting, ozone and a waterfall.
Treat those figures as the starting configuration for this model rather than a universal constant. Options recorded in the catalogue for the range include control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps — and availability and compatibility vary by model. When you request a quotation, ask for the equipment schedule to be restated line by line against your order, so what you approve is what ships.
Compare within the same length class before you commit
The most common mistake is comparing a swim spa against nothing. Two close relatives in the catalogue make the trade-offs visible:
- Outdoor Swim Spa WS-S07B-T — listed at 7000 × 2200 × 1365 mm, with one water pump, a jet total of 44 pieces and a listed total power of 8.75 kW, and a swim training system recorded in its specification instead of a waterfall.
- Outdoor Swim Spa WS-S07M — listed at 7000 × 2200 × 1480 mm, with three water pumps, a jet total of 40 pieces and a listed total power of 10.75 kW, plus waterfall and four water columns.
Same length, same width, different purpose. If the brief is daily lap swimming and lower connected load, the -T variant's recorded swim training system is the relevant feature to price. If the brief is hydrotherapy and a visual water feature for a resort or villa pool terrace, the waterfall and water column arrangements on the other variants do more for the experience. Decide which job the water has to do before you decide which shell to buy.
Confirm the electrical and thermal reality early
A listed total power figure is a planning number, not an installation drawing. Before production starts, confirm with your engineer: the supply capacity available at the property, the circuit protection and isolation arrangement, the routing of the power feed, and whether a heat pump and insulation are included in your configuration or quoted separately. Insulation and heat pump choices change both the running profile and the comfort of the spa outside the warm season, so they belong in the budget conversation from the first quotation rather than at handover.
Electrical codes differ by country and by municipality. Anything we can confirm is what the equipment delivers; local compliance sign-off belongs to your licensed installer and local authority, and should be arranged in parallel with production, not after delivery.
Treat water treatment as an operating decision
Ozone is shown for WS-S07B, and UV sterilisation appears among the catalogue options. Both reduce — but do not remove — the need for routine sanitiser management. The practical questions to settle before ordering are how the filter pump and filtration type are specified (the range lists a filter pump as standard and sand filtration as an option), where chemicals will be stored, and who maintains the unit once it is handed over. For hotels and clubs, this determines whether housekeeping can run the spa or whether a contractor is required.
Buy it as part of the outdoor package
A swim spa rarely sits alone. Deck levels, loungers, shading structures and storage all have to agree with the shell dimensions and the traffic flow around wet feet. Sourcing these together reduces conflicting trades on site: the same swimming pool range covers different lengths and feature sets, and the outdoor collections — pergolas, loungers, dining and sofa sets — can be coordinated with the spa layout in one specification. Our Custom & OEM Service covers bespoke sizes, finishes and material choices where a project needs something beyond the published models.
For buyers coordinating more than the spa itself, our Logistics & Door-to-Door Delivery service handles freight and documentation, and Installation & After-sales Support covers commissioning, inspection and spare parts. Freight terms, duties and site-readiness requirements are confirmed project by project.
A pre-order checklist
- Site: slab or plinth design, clear delivery route, lifting plan, drainage around the shell.
- Specification: equipment schedule restated line by line — pumps, jets, lighting, control system, options included or excluded.
- Power: supply capacity, circuit protection, feed routing, and whether heat pump and insulation are in scope.
- Water: filtration type, sanitiser regime, ozone or UV option, chemical storage, access for filter servicing.
- Accessories: steps, cover, seating edges, deck interface details.
- Commercial: Incoterms and delivery point, packaging and container loading, inspection points before shipment, spare-parts list.
Work through those six items and the quotation stops being a price and becomes a plan. That is the informed decision worth making.
