A swim spa that measures well on paper can still fail on site. The usual reasons are not the shell or the jets — they are the things buyers leave out of the enquiry: who supplies the steps, what the circuit has to carry, who lifts the unit onto the deck, and what happens when a spare pump is needed two years later. If you are specifying an Outdoor Swim Spa WS-PC03 for a villa terrace, a resort garden or a hotel outdoor leisure area, the checklist below is the order we recommend working through, item by item, before you request a quotation.

1. Confirm the water footprint and the total footprint separately

The catalogue figure for WS-PC03 is 3000 × 3000 × 1000 mm. That is the unit, not the installation. Write three numbers on your drawing before anything else:

• Shell footprint — the 3 m × 3 m plan area and the 1 m depth shown in the catalogue.
• Access envelope — the clear route from the delivery vehicle to the final position, including gate width, turning radius, overhead wires and any step or ramp. A rigid acrylic-shell unit cannot be bent around a corner.
• Service clearance — permanent access to the control system, water pump and filter pump. Pumps and filters need inspection without removing decking or furniture every time.

Also decide early whether you want the unit above the deck line, flush with it, or partly recessed. Recessing changes drainage, waterproofing and access-panel requirements, and those trades have to be briefed before the slab is poured — not after the spa arrives.

2. Match the water system to how the spa will actually be used

The WS-PC03 configuration shown on the site lists a jet total of 50 pieces with 4 water columns, one water pump and one filter pump, one control system, one LED light, and ozone as a displayed feature. Read that list against your programme:

• Guest-facing use (hotel, resort, club). Jets and water columns are the selling experience; ozone supports water quality between bathers. Ask how the jets are zoned and whether they can be switched from the control system rather than at the pump.
• Private residential use. Think about seating depth, jet placement for the shoulder and lower back, and how many people sit in the water at once. A spa used by two adults and two children behaves differently from one used for a nightly ten-minute soak.
• Therapy or maintenance use. Jet count alone does not tell you about pressure or layout, so confirm the jet arrangement with the supplier and, where possible, see the same model installed before committing.

The site does not list a swim training system for WS-PC03. If end-to-end swimming is a requirement rather than a nice idea, raise it in writing at the enquiry stage and ask which configuration or which alternative model in the Swimming Pools and Swim Spas range delivers it.

3. Settle power, not just total connected load

The catalogue shows a total power figure of 2.75 kW for this configuration. Treat that as the starting point for an electrical discussion, not the end of it. Before you order, confirm with your electrician:

• Supply voltage and phase — single or three phase at the spa location.
• Dedicated circuit, cable size, run length and protective device rating.
• Earthing and equipotential bonding arrangements for a wet outdoor environment.
• Where the isolator and control system sit, so they stay reachable and out of standing water.

If you later add a heat pump, the electrical demand changes with it. Size the supply for the finished specification, not for the base configuration alone.

4. Decide which options are in scope and who supplies them

The catalogue lists control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps as options for this range. Availability and compatibility vary by model, so each line needs a yes or no on your quotation rather than an assumption:

• Heat pump — the main lever on year-round usability in cooler climates; confirm output and control integration.
• Insulation — affects heat retention and running cost, and matters most where the spa sits exposed to wind.
• Filtration — confirm whether the filter pump shown is paired with sand filtration or cartridge media, and what the consumable replacement cycle is.
• UV sterilisation — complements ozone; ask how it is maintained and by whom.
• Steps — often quoted separately and frequently discovered late. Specify them with the spa so entry height and finish match the deck.

5. Plan the base, lifting and delivery route

A rigid unit needs a level, structurally adequate supporting surface rated for the weight of the shell when full of water plus occupants. Confirm who is responsible for:

• The slab, plinth or reinforced deck, including drainage away from the shell.
• Offloading and lifting onto that surface — crane, forklift or manual crew, depending on access.
• Protection of finishes along the route (paving, glass, landscaping).

Where the project sits offshore, delivery scope is part of the specification. SANTERSON describes freight forwarding by sea, air and rail with customs paperwork, packaging and container loading, shipment tracking and door-to-door delivery under its Logistics & Door-to-Door Delivery service. Ask for the Incoterms in writing, confirm who handles import clearance and duties at your port, and check insurance cover — marketing descriptions of coverage are not a substitute for a named delivery term on your order.

6. Check after-sales before you sign, while it still has value

A swim spa is a set of electro-mechanical components in permanent water. Before ordering, get written answers to:

• What the warranty covers on the shell, the pumps, the control system and the jets, and for how long.
• Which parts are stocked as spares, where they ship from, and typical dispatch time.
• Who performs installation and commissioning on site, and what inspection or snag list closes the handover — see Installation & After-sales Support.
• What ongoing maintenance support looks like once the unit is handed over.

Response times and warranty terms are only as good as the contract behind them, so get both in writing rather than relying on website claims.

7. Coordinate the spa with the rest of the outdoor package

The pool deck rarely fails as one item; it fails as a set of mismatched items. Frame finishes, cushion fabrics, screen colours and lighting temperature should be decided together. As a furniture and building materials manufacturer working on villa and hospitality projects, SANTERSON supplies loungers, cabana daybeds, pergolas, hardtop gazebos, outdoor dining and sofa sets alongside pool-side equipment, and offers Custom & OEM Service for finishes, dimensions and branding. One purchase order across the deck removes a whole category of coordination risk: two suppliers each blaming the other for a level or finish discrepancy.

8. Run the supplier questions you would not ask in person

Send these five questions to every quotation you collect, and compare answers side by side:

• Which exact model reference is being quoted, and does it match the datasheet attached?
• What is included in the price — options, steps, control system, delivery, installation?
• What are the electrical requirements for the quoted configuration specifically?
• What is the production lead time and the named shipping term?
• Which components carry warranty, for how long, and where do spares come from?

Five matching answers means the market is consistent. Five different answers usually shows which supplier has built and delivered this product before.

Quick reference: what the catalogue shows for WS-PC03

These are catalogue figures for the configuration published on the product page. Confirm included equipment and electrical requirements for the configuration you actually order — that confirmation should be in writing before payment.

The checklist, in one line each

• Shell footprint, access envelope and service clearance drawn separately.
• Jets, water columns and ozone matched to real usage patterns.
• Supply, phase, dedicated circuit and bonding agreed with the electrician.
• Heat pump, insulation, filtration, UV and steps priced as separate lines.
• Base construction, lifting and delivery scope assigned to a named party.
• Warranty terms, spare-parts supply and commissioning confirmed in the contract.
• Pool deck specified as one coordinated package, not five separate purchases.
