Start with the shell footprint, not the model number

The catalogue entry for this model shows a shell of 5000 × 3000 × 900 mm. Treat those figures as the starting point for two separate drawings: the excavation or plinth outline, and the access route from the shipping container to that outline. A 5-metre shell rarely travels through a built-up side gate without a lift, so confirm the delivery path before the slab is poured, not after.

Depth matters more than length for daily use. At 900 mm the seating and jet positions sit shallower than deeper configurations in the same range, which changes where adults can sit comfortably and where children can stand. Ask us for the internal seat and step layout drawings and check them against how the spa will actually be used — lap swimming, hydrotherapy sessions, or children's play.

Confirm what is included in your configuration

This model belongs to a configurable outdoor swim and hydrotherapy range, so two orders under the same model code can arrive with different equipment. The catalogue sheet for this unit lists one control system, one water pump, one filter pump, 30 jets and one LED light, with water jets, LED lighting and ozone shown as fitted features.

Options such as UV sterilisation, a heat pump, sand filtration, additional insulation and steps are listed separately in the catalogue, and availability varies by model. Get them itemised on your quotation rather than assumed: an unlisted heat pump or insulation pack changes both the delivered price and the running cost you will quote to your client.

Figures above are transcribed from the catalogue page for this model. A swim training system is not listed for this configuration, so if lap or counter-current swimming is part of the brief, raise it at specification stage rather than expecting it in the base unit.

Put the electrical load in writing with your local contractor

The catalogue states a total power figure of 2.45 kW for this configuration. Use it as a sizing input, and then have your Australian electrical contractor confirm supply capacity, protection and wiring against the conditions at site before any cable is ordered. Heater options, a heat pump or added lighting change that load, so the number you hand to the electrician must be the number for the exact specification you signed.

We do not certify the installation to local requirements — your contractor and certifier handle that. What we do supply is the equipment schedule, wiring entry points and control-system details they need to design around. Send us their questions early; a mismatch discovered on site costs far more than an email exchange.

Match drainage, substrate and access to the site conditions

• Confirm whether the unit sits on a prepared plinth, a deck frame or below finished level, and who supplies that substructure.
• Confirm overflow and drain connections, plus where first-fill and maintenance water discharges to.
• Confirm clear opening dimensions for the shell on delivery day, including gates, overhead wires and any covered walkway.
• Confirm how the unit will be lifted or set into position, and which party provides that equipment.

These are the four items most often left out of a purchase enquiry, and they are also the four that cause the most expensive delays once the container is booked.

Decide maintenance access before handover

Filter pumps, control systems and jet lines all need reaching. Ask where the service panel faces, how much clearance the manufacturer allows around the shell, and whether plant components can be removed without pulling the spa out of its housing. On resort projects this decides whether a technician can work outside guest hours.

Water treatment is the other half of upkeep. Ozone is shown as a fitted feature on this configuration; UV sterilisation appears as an option in the range. Decide at quotation stage which one your client will run, because it determines the consumables they buy and the routine their maintenance contractor follows.

Compare configurations across the range, not just one model code

Santerson publishes a configurable swim spa range rather than a single fixed product. The related Outdoor Swim Spa WS-PC05, for example, is catalogued at 5000 × 3000 × 1100 mm with a different jet count and lighting arrangement. Same plan area, greater depth — exactly the kind of difference that decides whether a spa suits a seated hydrotherapy programme or a more active one.

If your project also needs poolside lounging and shaded seating in the same outdoor zone, our Furniture Series covers aluminium frames, rope weave, wicker and teak-look tops, so the spa and the surrounding furniture can be coordinated through one specification process instead of several.
