A swim spa quotation for a hotel, resort, club or residential tower rarely arrives as one number. It arrives as a shell, a list of pumps and jets, an electrical load, a freight line and a set of options that will be priced later. The WS-SP500 outdoor swim spa is a useful reference point for that review, because its catalogue specification sheet shows exactly which items have to be lined up before the total price means anything. The figures below are the ones shown on the product pages for the WS-SP500 series; they should be confirmed against the final agreed configuration.

Start with the footprint, not the price

The catalogue records the WS-SP500 at 5000 × 2500 × 1600 mm. Treat those as the starting envelope for site work rather than the final one. Delivery access, whether the unit is set on a slab, a deck or a podium, and where the plant and controls sit all change the civil and structural scope. Ask for the base plan and the elevation in the proposal, then check them against the drawings your contractor already has.

Compare the envelope across the range before you commit. The WS-SP600 is listed at 5900 × 2500 × 1600 mm, so the extra length can decide whether the unit fits an existing terrace bay or requires a re-plan of the pool deck.

Read the equipment schedule line by line

On the product page for the WS-SP500 the specification block shows one control system, one swim training system, one filter pump, six jets and four LED lights, with a total power figure of 9.35 kW; water jets, LED lighting, ozone and a swim training system are shown as features. The closely related WS-SP500-MS page lists a water pump, one filter pump, twenty-nine jets and 11.55 kW. Same footprint, a very different jet count and a different electrical demand. The jet count and connected load for this series sit inside that spread, and the two pages do not tell the same story for the same length of shell.

This is the single most common place where two proposals that appear identical are not. If your tender names one model and another supplier quotes a variant, the jet count, pump set and connected load explain the price gap. Require the supplier to state the model code, jet count, pump quantities and connected load in the quotation itself, not in a separate datasheet.

For a commercial venue the swim training unit and the jet array drive the user experience and the programming you can offer guests or members. A unit with a small number of jets reads as a lap product; a unit with a fuller jet array supports hydrotherapy sessions. Decide which programme the business is selling before you pick the specification.

Confirm options and running items separately

Catalogue options across this swim and hydrotherapy range include control systems, UV sterilization, water pumps, heat pumps, sand filtration, insulation and steps. Availability and compatibility vary by model. Heating and insulation are the two to settle early for a venue in a cool climate, because both change running cost and both are awkward to add after installation. Water treatment is the other one: state in the proposal which sterilisation method is included and what the routine dosing regime will be, since the housekeeping team inherits that duty on day one.

Make the electrical and commissioning scope explicit

The product guidance for this range directs buyers to confirm included equipment and electrical requirements for the selected configuration. For a commercial project that means the supply and protection arrangement, the location of the local isolator, control wiring, and who signs off the installation. Put all of it in the proposal, with a named responsibility against each item. A quotation that is silent on electrical scope transfers that cost and the programme risk to you.

Ask what handover documentation comes with the unit: as-built wiring arrangements, pump and control documentation, warranty terms and a spare-parts list. A facilities team can only maintain what it can document.

Score delivery, packaging and support in the same table

Freight is not a footnote on an imported spa. Door-to-door arrangements cover export packing, container loading, ocean freight, customs clearance and inland delivery to the site, and the point at which risk passes to the buyer must be clear. On a city site with restricted access, unloading and craning can be a line item of their own. The logistics and door-to-door delivery service is described as covering freight forwarding, customs paperwork, packaging, container loading, shipment tracking and delivery, which is the right scope to test a supplier against; ask for the packing list format and the shipping marks they will use so your site team can identify crates.

After installation, warranty coverage, spare parts availability and maintenance support decide whether the asset stays in service. Write these into the contract with response times and named parts, so the procurement is defensible when the operator raises it a year later.

Coordinate the spa with the wider fit-out

A swim spa is one line in a larger package of poolside and wellness-area products: paving, screens, storage, vanity units, lighting and the rest of the swimming pools and swim spas range. Buying them through one specification process reduces the number of trades coordinating on site. For multi-property owners, a single agreed model schedule with approved options and substitutions gives purchasing control across the estate, which is where the turnkey project solutions approach earns its keep on hospitality, residential and workplace work.

A short evaluation checklist

• Model code, jet count, pump quantities and connected load stated in the quotation itself.
• Base plan and elevation checked against site access, structural support and plant location.
• Heating, insulation, sterilisation and steps priced as named options, not excluded by default.
• Electrical supply, protection, isolator and commissioning responsibilities assigned by name.
• Delivery terms, unloading method and risk transfer point written into the contract.
• Warranty terms, spare-parts list and as-built documentation listed as handover deliverables.
• Like-for-like comparison across the range before the award recommendation is signed.

Those seven lines are the difference between an award decision that holds and one that unravels on site. If you are assembling a package for a wellness area, pool deck or residential amenity, send the drawings and the model schedule and we will return a specification and an itemised quotation for the outdoor swim spa configuration that fits the site.
