A swim spa quote is only as useful as the brief behind it. Two buyers can ask for the same model and receive prices that differ by a wide margin, because the number on the page is the shell and the real cost sits in pumps, treatment, insulation, site works and freight. If you are sourcing an Outdoor Swim Spa WS-S06M for a villa terrace, a resort garden or a private compound, the checklist below is what we ask our own project managers to fill in before a quotation is issued.

Start with the shell, not the price

State the model and the shell geometry you are being quoted. The WS-S06M is catalogued at 5900 x 2200 x 1610 mm, which is longer and deeper than several other entries in the same range. Footprint and water depth together determine water volume, and water volume drives pump sizing, heating load and the weight your slab has to carry. Ask the supplier to write the outer dimensions, the internal water depth and the filled weight in the quotation itself rather than in an attachment, so you can hand the same sheet to your structural engineer and your electrician.

If your site has a fixed opening, a parapet, or an access route that the shell must pass through on delivery, say so in the request. Shell dimensions that clear a plan view on paper sometimes fail on a stair, a lift or a gate on site.

List the water system line by line

The published specification for this model lists a control system (1 set), two water pumps, one filter pump, 48 jets in total, LED lighting (17 plus 17 small LED lights), ozone, four water columns and a total power figure of 6.95 kW. Ask for each of these as a separate line item with brand, model and quantity. A quote that bundles “hydrotherapy system complete” hides where a competitor has cut corners, and it also hides which items you will need spare parts for in five years’ time.

Note what is absent as well. In the specification currently published for the WS-S06M, no swim training system is listed for this model. If you want a swim current for lap training or physiotherapy, that has to be requested and priced as an addition, and it changes electrical load and jet layout. Equally, confirm whether the jets described as hydrotherapy jets are pressure-adjustable and where they are positioned relative to the seating benches.

Name the options you actually want

Catalogue options across this configurable range include control systems, UV sterilization, additional water pumps, heat pumps, sand filtration, insulation and steps. Mark each option as required, optional or excluded in your request. Three of these decide your running cost more than anything else:

• Heat pump — specify whether you need heating for year-round outdoor use in your climate, and ask for the performance figure and the noise level, not just “heat pump included”.
• Insulation — ask what is insulated (shell, cabinet, plumbing), with what material and to what thickness, because this is where heat loss and winter energy bills come from.
• Filtration and disinfection — state whether you want sand filtration, cartridge filtration, ozone, UV, or a combination, and how many filtration cycles per day the system is set for.

Steps, handrails, a cover and a chemical dosing unit are all small items individually and a meaningful sum together. Listing them in the first request keeps the comparison honest.

Give the electrical and site conditions up front

A total power figure of 6.95 kW means nothing to a supplier until you tell them what is available on site. Include in your request: supply voltage and phase (single or three phase), the frequency standard in your country (50 Hz or 60 Hz), the location and rating of the isolator and residual current protection, cable run length from the distribution board, and earthing arrangement. Electrical non-compatibility is the most common cause of a swim spa sitting on a pallet for months.

Also state the foundation condition: a level reinforced slab, a deck with confirmed load capacity, or a plinth yet to be poured. If drainage, a pump pit or an overflow is required, say so, because the shell, the cabinet base and the site works have to be designed together.

Specify the finish and the surrounding build

Say which cabinet finish you want, whether the shell colour has to match an existing palette, and where the equipment access panel must face. A spa delivered with the service hatch against a fixed wall becomes a maintenance problem on day one. If the spa is being clad into a terrace, deck or pool surround, send the cladding detail and the access dimension you intend to leave.

Where the swim spa is one part of a wider outdoor area, it is worth grouping it with the rest of the specification. Our Outdoor Furniture for Villas and Resorts pages cover the seating, lounging and shading that normally sits around a spa deck, and the Swimming Pools and Swim Spas category lists the other shell sizes in this range when a project needs to compare a shorter or longer basin.

Set the commercial and logistics terms you need

Ask for the quotation in a structure you can compare line by line across suppliers:

• Incoterm and named place, plus the packing method and the number of packages or containers.
• Estimated production time after deposit, and the shipping route rather than only a transit number.
• Who handles customs clearance and what documents are supplied: commercial invoice, packing list and certificate of origin.
• Final delivery address and whether a crane, tail-lift or forklift is needed at the ｄｒｏｐ-off point.
• What the warranty covers and excludes, what spare parts are recommended as a holding stock, and how a faulty component is replaced once the unit is installed.

For a project, also ask whether the supplier will coordinate commissioning support and the handover documentation your client or certifier may ask for. These are the practical differences between one supplier and another once the shell arrives.

A short template you can copy

Write the request as a table: model and shell size; required options and exclusions; pumps, jets, lighting, ozone and control system by brand and quantity; electrical supply and frequency; foundation and drainage condition; cabinet and shell finish; delivery term, address and site access; warranty and spares. Attach a photo of the site, a dimensioned plan and any section drawing that shows the access route.

That single sheet gets you comparable quotations against the same scope instead of three different products. If you are sourcing a spa alongside other fit-out packages — joinery, bathroom fixtures, terracing and outdoor furniture — the same brief works as a project specification. You can read how we structure that end-to-end process under Turnkey Interior Project Solutions, or send us the site drawings and the option list above and we will quote against it line by line.
