A swim spa quotation is easy to compare on price and hard to compare on substance. Two proposals for a seven-metre unit can look almost identical in the catalogue and still differ completely once you count pumps, read the electrical load and check what has been left out of the box. This guide uses Outdoor Swim Spa WS-S07B-T as the reference model and shows buyers, contractors and project procurement teams how to read a sample specification and a written proposal side by side before any deposit is paid.

Step 1: Confirm You Are Comparing the Same Configuration

Model codes in this range carry suffixes, and the suffix changes what you receive. A WS-S07B quotation is not interchangeable with a WS-S07B-T quotation: the -T listing shows a swim training system, and its equipment list differs from the base model. Write the exact code on your request for quotation and repeat it on every comparison sheet you build.

Also check whether the sample or specification sheet you were sent belongs to the model being priced. Suppliers often attach a generic page from the same family. If the dimension block does not match, ask for the configuration sheet for that code before going further.

Step 2: Start With the Published Specification, Not the Price Line

The catalogue record for WS-S07B-T lists a shell of 7000 × 2200 × 1365 mm, one control system, one swim training system, one water pump, one filter pump, 44 jets in total, three LED lights plus 26 small LED lights, and a total power figure of 8.75 kW. The features shown are water jets, LED lighting, ozone and the swim training system. Compare that with the Outdoor Swim Spa WS-S07B record: 48 jets and 13.35 kW in a shell of 7000 × 2200 × 1335 mm, with a waterfall instead of a swim training system.

Treat that block as the baseline your suppliers must answer against. If a quotation for the same model name shows different numbers, ask which configuration is being priced rather than assuming one of the two documents is wrong. Catalogue options across this range include control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps, and availability varies by model.

Step 3: Compare the Configuration Before You Compare the Number

The clearest way to see how much a specification can move inside one product family is to place WS-S07B-T next to models around it in the same catalogue.

Two points stand out and both belong in your evaluation sheet. First, a longer shell does not mean a heavier electrical load: the 10 m and 11.7 m units above are listed at 7.65 kW while the 7 m WS-S07M sits at 10.75 kW because it carries more pumps and additional water features. Second, jet count tracks how the unit is meant to be used rather than its quality — the Outdoor Swim Spa WS-S10-T lists more jets than the 7 m models in the table above at a lower listed power figure.

If your priority is a compact swim-and-soak footprint, compare WS-S07B-T with the shorter Outdoor Swim Spa WS-S06CT, which lists 31 jets at 8.35 kW in a 5880 mm shell. If the brief is hydrotherapy and visual impact over lap swimming, models such as Outdoor Swim Spa WS-S07M add a waterfall and water columns in the same 7 m length.

Step 4: What a Sample Specification Should Confirm Before Production

For a made-to-order swim spa, ask for a written configuration sheet signed back by the factory before mass production begins. It should settle these points in plain language:

• Exact shell dimensions and the direction of the steps, so you can set out the deck, access path and any plant room.
• Included versus optional items: control system, swim training nozzle, pumps, filter, ozone, UV, heat pump, insulation and steps, each priced separately.
• Total power for the configuration you have chosen, plus the supply it assumes — single phase or three phase, voltage and dedicated circuit.
• Cabinet colour, acrylic shell finish and lighting arrangement, matched to the sample image on the product page.
• Drainage, overflow and maintenance access, including where the filter pump sits and how it is reached after installation.
• Packing method and container loading plan, so you know what arrives together and in how many consignments.

A useful test: send two suppliers the same list of requirements and ask each to return their standard sheet unchanged. Where a supplier answers your list line by line, you can compare like with like. Where one returns only a price, the gap is what you will be arguing about later.

Step 5: Reading the Proposal — Five Lines That Decide Total Cost

1. Freight terms and who carries the risk

Confirm whether the quoted price is ex-works, FOB or delivered to site, and check what the seller handles for customs paperwork, packing lists and certificates of origin. Our furniture logistics and door-to-door delivery service covers sea, air and rail freight with shipment tracking, but the incoterm, duties and local delivery scope still need to be agreed project by project.

2. Site preparation and utilities

A swim spa needs a level load-bearing base, a dedicated electrical circuit sized for the listed total power, water fill and a drainage route. None of that sits in the product price. Put it in the same comparison table so you are judging installed cost rather than ex-factory cost.

3. Options priced separately

Heat pumps, insulation, sand filtration and UV sterilisation change both the purchase price and the running load. Ask for them as line items so a cheaper quote that excludes them is visible as such.

4. Spares and after-sales scope

Ask which pumps, jets, seals and control parts are stocked, how replacements are shipped, and what the warranty covers for the shell, cabinet and electrical components. Furniture installation and after-sales support is part of our service scope; the specific terms and exclusions should still be written into your contract.

5. Coordination with the rest of the outdoor package

A pool terrace rarely stops at the spa. If loungers, a shade structure and paving are being bought from different suppliers, you carry the coordination cost. Where they come from one source, finishes and dimensions get specified together — see outdoor furniture for villas and resorts, and pairings such as a double roof hardtop aluminum gazebo with privacy curtains beside the pool deck.

Step 6: Score the Proposals Side by Side

Score each proposal out of five on four items that matter and record the evidence, not the impression:

• Specification match — does every line answer the configuration sheet you sent, including pump count, jet count and total power?
• Transparency of exclusions — are freight, site works, options and spares listed as included or excluded in writing?
• Documentation quality — packing list, electrical schedule and dimensional drawing provided before order confirmation.
• Installed cost — product plus freight plus duties plus base, power and drainage works, on one page.

Two proposals that are close on price usually separate on the second and third items. That is where project delays start.

Step 7: Close the Gap in Writing Before the Deposit

Send each supplier the same short list of questions and put their answers into the comparison sheet. The questions that matter most are usually the ones a price-only quotation leaves out.

Once those answers come back in writing, attach them to the purchase order. If a later delivery differs from that record, you have something specific to point to instead of a general complaint.
