A compact square swim spa looks simple on a spec sheet: three metres by three metres, one shell, done. In practice the model that fits one villa terrace can be the wrong choice for the next project, because the surrounding conditions decide what the unit needs to carry. The questions below are the ones we work through with architects, builders and procurement teams before Outdoor Swim Spa WS-PC03 is quoted, and they apply to most of our configurable outdoor swim and hydrotherapy range.

1. What the site actually gives you to work with

WS-PC03 sits in a family of configurations rather than a single fixed product, so treat the published numbers as a starting point and confirm the exact build for your project:

ModelWS-PC03
Catalogue dimensions3000 × 3000 × 1000 mm
Jet total50 pcs, including 4 water columns
Water pump / filter pump1 pc each
Control system1 set
LED lights1 pc
Total power2.75 kW
Features shownWater jets, LED lighting, Ozone
Swim training systemNot listed for this configuration

The square 3000 × 3000 mm footprint is the defining detail. It buys an even, usable interior instead of a long lane, which suits hydrotherapy, soaking and short swim drills around a jet wall. It is not the model to choose if the client's brief calls for continuous lap swimming against a current. For that, look at longer configurations in the same range, such as Outdoor Swim Spa WS-PC05 or Outdoor Swim Spa WS-PC08T.

2. Site access, structure and the slab

A three-metre square module has to reach its position. Ground-floor garden pads are straightforward; rooftop terraces, podium decks and sunken courtyards are not, and the crane route, lift capacity and finished floor loading all have to be settled before the shell is manufactured.

Confirm with the structural engineer: the bearing area under the full shell, whether a perimeter upstand or recessed surround is required, drainage falls around the unit, and access panels for the pump, filter and control set. We build to the dimensions you approve, so if a recess or plinth changes the seat height, tell us at drawing stage rather than at handover.

3. Power supply and electrical zoning

The catalogue figure for this configuration is 2.75 kW total power. That number covers the standard equipment listed above; it does not cover options, and it is not a substitute for the local electrical design. Before ordering, confirm with your electrician:

  • Supply capacity, circuit rating and protection at the intended distribution point
  • Cable routing and containment from the supply to the unit's control position
  • Which circuits serve the jets, filtration cycle and lighting, and how they are switched
  • Local requirements for bonding, isolation and equipment in wet zones on your site

Adding a heat pump or extra pumps changes the load. Decide the option list first, then let the electrical design follow it - not the other way round.

4. How the spa will actually be used

Usage drives the jet layout, seating and water features far more than aesthetics does:

  • Resort and hospitality poolsides: bather load, supervision, maintenance routine and hours of use. The 50-jet layout with 4 water columns reads well as a feature element, but the plant room and dosing arrangement need to support daily turnover.
  • Private villas: who uses it and when. Evening soaking and low-season use push the conversation towards insulation and heating options; daytime family use pushes it towards depth, steps and safe entry.
  • Wellness and rehabilitation use: jet positions relative to seating ledges, and whether water columns or targeted jets matter more for the programme.

Send us the room data sheet or a simple usage note. It changes what we recommend far more than a brochure reference image does.

5. Options that are not in the base list

Catalogue-listed options for this range include control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps. Availability and compatibility vary by model, so each line is confirmed against the specific configuration rather than assumed:

  • Heat pump - extends shoulder-season use; adds an electrical and plant consideration.
  • Insulation - relevant wherever the spa runs outside warm months or sits exposed on a deck.
  • UV sterilisation / sand filtration - alternative or additional water treatment where ozone alone does not meet the maintenance plan.
  • Steps and access - entry height depends on the finished surround, so fix this with the landscape detail.

Water treatment choice also affects the maintenance schedule handed to the operator. We would rather agree that schedule at quotation stage than discover it during commissioning.

6. Surrounds, finishes and coordination with other trades

A swim spa rarely arrives as an isolated item on a project schedule. It sits inside decking, cladding, paving, lighting and sometimes outdoor furniture around the poolside. Because we supply furniture and building materials alongside water features, one purchase order can cover the spa shell, the deck-adjacent seating and the finishes that frame it - which removes the usual argument between suppliers about who owns the interface detail.

Share the landscape or architectural drawing early. We need the finished levels, the surround material build-up, and where inspection access is expected to be maintained after handover.

7. Delivery, installation and after-sales on your site

Our project services cover design consultation and specification, manufacturing and quality control, freight and door-to-door delivery, then installation support and after-sales. For an imported swim spa the practical checkpoints are the delivery date against the site programme, packaging and container loading, customs documentation, and who performs setting, connection and commissioning on site.

Terms, duties, transit time and the division of installation responsibility are confirmed per project, so we treat them as part of the quotation rather than as a general promise.

A short pre-order checklist

  • Confirmed site position, lift route and structural sign-off
  • Finished levels and surround build-up from the landscape detail
  • Final option list, including heating, insulation and water treatment
  • Electrical design based on the confirmed configuration
  • Usage brief: bather load, hours of use, maintenance owner
  • Delivery programme, documentation set and commissioning responsibility
If you can send the location drawing, intended usage and target completion date, we will confirm which configuration in the outdoor swim and hydrotherapy range fits - WS-PC03 or a longer model - with dimensions, options and electrical requirements stated for that specific build.
