A swim spa sits on a villa or resort bill of quantities as a single line item, yet it carries structural, hydraulic and electrical consequences at the same time. Written loosely, it comes back later as a variation order. Written properly, the Outdoor Swim Spa WS-SP600 specification becomes the one reference that the architect, the civil contractor, the electrician and the supplier all work from. Below is the structure we ask project teams to follow when the brief reaches us, using the WS-SP600 as the worked example.
Start with the envelope, not the water features
The catalogue footprint for this model is 5900 × 2500 × 1600 mm. Treat those three numbers as the starting constraint for the deck, not as a finished installation size. In a procurement brief we want to see the envelope stated alongside the clear access route from the delivery vehicle to the final position: the shell reaches site as one unit, and once the paving is laid there is no re-routing it.
Two dimensions matter more than the footprint itself: the depth of the prepared base and the working clearance around the cabinet for later servicing. State in the brief who supplies the load-bearing base, who levels it, and how much perimeter access the maintenance team will have after handover. A specification that records only length and width will not answer those questions on site.
List the fitted equipment line by line
The published specification for the WS-SP600 shows one control system, one swim training system, one filter pump, six jets in total, four LED lights and a total power figure of 9.35 kW. Copy that list into your brief as a table rather than as prose, and add a status column — included, optional, or to be quoted separately. That column is what stops an assumption becoming a claim on the contractor.
| Item | Shown in catalogue for WS-SP600 | Confirm before order |
|---|---|---|
| Shell dimensions | 5900 × 2500 × 1600 mm | Base design and access route |
| Control system | 1 set | Mounting position, user access |
| Swim training system | 1 set | Intended use: lap swimming or fitness |
| Filter pump | 1 pc | Filtration duty vs. local usage pattern |
| Jet total | 6 pcs | Hydrotherapy scope required by the client |
| LED lights | 4 | Switching and lighting circuit |
| Total power | 9.35 kW | Supply capacity, protection, dedicated circuit |
Note the jet count carefully. The catalogue also carries a WS-SP600-MS variant at the same 5900 × 2500 × 1600 mm envelope, but with 29 jets, an additional water pump and a total power figure of 11.55 kW. Same plan area, different electrical load. If your brief names only "WS-SP600 class, 5.9 m", the electrician will size for the wrong number.
State the power requirement as a design input
Total connected load is the line most often left out of a landscape specification. For this model the catalogue figure is 9.35 kW; for the -MS variant it is 11.55 kW. Both belong in the electrical drawings, together with the circuit route, the isolation point and who is responsible for the final connection. We supply the equipment data, but the local supply arrangement, protective devices and the installed electrical work are confirmed by the project's electrical engineer for the specific site.
Separate fitted items from catalogue options
The swim range lists optional accessories including control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps. Availability and compatibility vary by model, so each option should appear in the brief as its own priced line with a confirmation date attached, rather than folded into a general description of the spa. Where a client wants a hydrotherapy pool shaped to the terrace — square, round, oval or curved — that is a separate scope and belongs on a separate line item, because the shell, the base and the lead time all change.
Record the site conditions you already know
- Exposure: open terrace, sheltered courtyard or internal void — this drives the insulation and heating discussion.
- Substrate: timber deck, concrete slab or podium structure, and who signs off the load calculation.
- Drainage and overflow route, including where commissioning water goes.
- Lifting and cranage access on the delivery date, with a site photo attached to the enquiry.
- Handover sequence: whether the spa is installed before or after surrounding finishes.
These five points cost nothing to answer at enquiry stage and are expensive to answer through a variation order later.
How we support a swim spa line item end to end
SANTERSON has been manufacturing furniture and building materials in China since 2008, and a swim spa usually reaches site as part of a wider package rather than on its own — outdoor furniture, pergolas, loungers and the finishes around the deck are commonly ordered in the same container. Because design coordination, production, freight and door-to-door delivery sit under one scope, the spa specification stays aligned with the rest of the outdoor package instead of being tendered across three separate suppliers.
Send us your draft brief and we will mark up the equipment list, the electrical load and the base requirements for coordination with your design team. For a full model overview, see the swim spa and swimming pool range.
