Outdoor swim spas rarely arrive at a project as a single standard box. The same shell can be specified for a resort terrace, a private villa garden or a wellness floor, and the difference sits in the equipment list around the cabinet. If you are sourcing the Outdoor Swim Spa WS-S07B for a villa, hotel or landscape project, the conversation with the factory should cover far more than the shell size. Below is the shortlist of customisation decisions that shape price, site preparation and daily running cost, written for procurement teams, contractors and interior designers who need a specification they can sign off.
Start from the published base specification
The catalogue record for the WS-S07B lists a cabinet of 7000 × 2200 × 1335 mm, one control system, three water pumps, one filter pump, 48 jets in total, three LED lights with 26 small LED lights, and a total power figure of 13.35 kW. The features shown on the product page are water jets, LED lighting, ozone and a waterfall. Two points matter before any customisation talk begins. First, a swim training system is not listed in the captured specification for this model; the sister variant, the Outdoor Swim Spa WS-S07B-T, lists 7000 × 2200 × 1365 mm, one swim training system set, one water pump, 44 jets and 8.75 kW total power. If lane swimming is a project requirement, confirm whether the specification should follow the WS-S07B or the -T variant, because the jet count, pump count and power load move with that choice. Second, treat every number above as the catalogue baseline for the selected configuration, not as a guarantee of what arrives on site. Ask for the final equipment schedule in writing, matched to the model code on the quotation.
Equipment and performance options to settle early
- Pump and jet layout. The split between massage jets and circulation pumps drives both the purchase price and the electrical supply. Agree the number and position of jets against how the spa will actually be used — daily exercise, guest hydrotherapy, or children's play — and ask which pumps are dedicated to the jet circuit and which to filtration.
- Swim training unit. A current-based swim unit changes the hydraulic design and the depth of the swim channel. Where continuous swimming is the primary brief, confirm the unit type, its flow direction and whether the cabinet height has been adjusted to suit it.
- Water features and lighting. The waterfall and LED circuits are options to itemise rather than assume. Specify the number of fixtures, the colour mode and whether the lighting is zoned so that feature lights can run without the main pool lights.
- Sanitisation route. The base model shows ozone. Catalogue options include UV sterilisation and sand filtration. Decide the sanitation package at quotation stage, since it affects the plant space beside the cabinet, the spare-parts list and the maintenance routine handed to the facilities team.
Heating, insulation and the running-cost conversation
The total power figure on the specification sheet is the number buyers quote internally, but the heat source is a decision, not a given. Heat pumps are listed among the catalogue options, and the same option list includes insulation and steps. For a spa used year-round in a cool climate, specify the heating method, the insulation package for the shell and base, and the cover type together, because the three determine steady-state energy demand far more than the pump rating does. Ask the factory for the expected heating load under your target water temperature and ambient conditions for the project location, and put that figure in the same document as the equipment schedule. For hotel and resort installations, request the standby and circulation settings as well; a spa that filters on a timer overnight behaves very differently on the meter from one that runs continuously.
Finishes, access and site integration
Cladding and cabinet finish are customisation items that architects should not leave to the default. Match the exterior panels to the terrace, deck or landscape material, and confirm which finishes are available for the model line you are specifying before the design intent is frozen. Access is the second decision: steps are listed as an option, and the choice between integrated steps, a deck-level entry or a raised platform changes the substructure, drainage and waterproofing detail around the spa. Send the factory the finished level, the plant room or equipment access route, and the service clearance requirement, so the cabinet arrives with access built into the design rather than retrofitted on site.
Where a project needs a non-standard footprint, SANTERSON also publishes a customizable shape outdoor spa built on an acrylic shell with structural reinforcement, offered in square, round, oval and curved configurations for gardens, terraces and leisure areas. For a WS-S07B enquiry, ask directly which of those shape and shell options apply to the model and which do not, rather than assuming a bespoke geometry carries over between product lines.
Electrical, delivery and handover details
Electrical requirements are the most common source of delay on swim spa projects. Supply the factory with the available supply at the cabinet position, the phase and voltage at site, and the local wiring rules your contractor will work to, then confirm the required circuit rating, protection device and isolator position against the final specification. The same applies to delivery: SANTERSON describes custom and OEM service, door-to-door logistics and installation and after-sales support among its services, so agree the container configuration, the offload method, the crane or forklift requirement and who performs commissioning before the unit ships.
A short written checklist before order confirmation covers the ground: the exact model code and its dimension set; the pump, jet and swim-unit configuration; the sanitation and lighting package; the heating and insulation specification; the cabinet finish and access design; the electrical schedule; and the delivery, installation and commissioning responsibilities. Buyers who settle those items with the manufacturer at the quotation stage avoid the change orders that arrive once the cabinet is already on the crane. For a project enquiry on the WS-S07B or a comparison across the wider swim spa and swimming pool range, send the drawings and site conditions with the enquiry so the returned specification reflects the project rather than a catalogue page.
