An outdoor swim spa rarely fails on its own. It fails at the edges: the slab that arrives too small, the power feed that stops short of the cabinet, the loungers ordered three weeks later in a different metal finish, the drainage that was never routed where the service panel needs it. In villa and hospitality projects where SANTERSON supplies the swim spa together with outdoor furniture, building materials and interior fixtures, those edges are decided long before the shell is loaded. This article walks through how to plan the Outdoor Swim Spa WS-115AⅢ-U as one part of a single outdoor package, so the pool deck, the seating, the shade structure and the wet services are drawn against the same dimensions on the same set of drawings.

What the WS-115AⅢ-U record actually fixes for you

Before anything is coordinated, be clear about which numbers are settled and which are still open. The catalogue record for this model gives a footprint of 3880 × 2200 × 1250 mm, a control system of one set, four water pumps, one filter pump, a jet total of 23, LED lighting, and a total power figure of 11.85 kW. Features shown for this configuration are water jets, LED lighting and ozone; the swim training system is not listed on the WS-115AⅢ-U specification record, so it must not be assumed, and the electrical and equipment inclusions of the chosen configuration should be confirmed with us before any electrical drawing is issued. The same record lists options such as UV sterilisation, additional water pumps, heat pumps, sand filtration, insulation and steps — items that change both the machine room footprint and the power load, and therefore need to be decided before the wet services are drawn, not at handover.

Practical consequence: treat the 3880 × 2200 mm footprint as the planning dimension and add your own working clearance on the pump and control side, because four water pumps plus one filter pump need access for maintenance. Where the spa sits against a wall or a planter, that access has to be reserved in the paving layout. Confirm the finished height of the surround against the 1250 mm catalogue height so the water line, coping level and step arrangement are read from one dimension, not two.

Read the same model number across the range

The WS-115AⅢ and WS-115AⅢ-U share the same 3880 × 2200 × 1250 mm footprint and the same 11.85 kW total power figure, but they are not interchangeable on services. The WS-115AⅢ record shows one water pump and a listed swim training system, whereas the WS-115AⅢ-U record shows four water pumps and no swim training system. A plant zone sized for one pump body will not accept four. So if a design is being switched between the two, or between a 115 and a longer shell, the pump zone, cable runs and access doors have to be redrawn rather than carried across.

The same caution applies up the range. The Outdoor Swim Spa WS-130AⅢ-U is recorded at 8000 × 3000 × 1400 mm against the same 11.85 kW catalogue figure, so it is a longer shell carrying the same headline power number but a very different footprint. Where a client is comparing shell lengths, treat the power figure as a starting point only: the useful comparison is the pump count, the LED count, the jet total and the access arrangement, since these drive the civil and electrical work. Luxury Outdoor Swim Spa with Massage Jets, LED & Water Features and Customizable Shape Outdoor Spa, Personalized Hydrotherapy Pool are also listed in the same swimming-pool range, and where a bespoke shape is under consideration the shell geometry has to be frozen before the deck setting-out is fixed.

Decide the wet services and the power before the paving is set out

On the WS-115AⅢ-U the services conversation has four parts, and all four belong on the drawing set at the same time as the spa position:

• Structure and base. A prepared, level load-bearing base in the exact 3880 × 2200 mm footprint, with the maintenance side kept clear of fixed planting, balustrades and permanent furniture.
• Power. The catalogue total power figure of 11.85 kW is the starting point for cable sizing and protection. Final circuit requirements depend on the selected configuration and local installation rules, and must be confirmed for the project rather than assumed from the catalogue.
• Filtration and drainage. The filter pump location, backwash route and any sand filtration option need a drain run. If the option is decided late, the drain has to be retrofitted.
• Access. Steps, control panel reach and pump access are all hard points. They should be drawn before coping, glass balustrading and decking are fixed.

One project detail worth flagging early: the catalogue records a model name written with the character "Ⅲ". When a model is quoted into a specification, a purchase order or an email chain, keep the full model name consistent and include the product link, so a "WS-115AIII-U" typed in plain text is not mistaken for a different shell.

Coordinate the pool deck furniture with the spa, not after it

Seating and shade are where an outdoor package either reads as designed or reads as three separate purchases. Choose the furniture families at the same time the spa position is drawn, so the metal finishes, the timber tones and the textile palette are set once.

The Aluminum Sling Sun Lounger Collection is the workhorse for high-use pool decks: textilene sling mesh that dries quickly, a stepless or multi-position back, and static, wheeled and folding frame versions so the layout can be changed as usage changes. Frame finish and sling colour can be matched to the project palette, which is the practical reason to specify it together with the spa surround — the same aluminium finish should appear on loungers, side tables and the shade structure.

For longer dwell time on the same deck, Rope Weave Outdoor Chaise Lounge & Round Daybed with Teak Armrest and the Aluminum Frame Outdoor Conversation Sofa Set with Teak Tabletop & Arm Caps carry the teak accents that read well against a wet deck. If the swim spa sits beside a conversation zone, plan the spray and splash line between them: low-profile seating is comfortable next to a spa, but it should sit outside the zone where jet turbulence throws water. Where a deck needs private retreats, the Aluminum Cabana Daybed Collection with privacy curtains works as the backdrop, and its aluminium frame suits the chlorine-rich pool environment.

Shade, shelter and the year-round use case

A swim spa is an all-year asset only if the space around it can be used in wind and rain. Two structures do most of the work:

• Motorized Louvered Aluminum Pergola with LED Strip & Zip Screens — rotating aluminium louvers that close against light rain, built-in LED strips instead of extra floodlighting, and zip screens on any side for low sun, breeze and privacy. Specify it before the electrical run, because the LED strips and the louver motor need a feed, and that feed should come from the same coordinated layout as the spa supply.
• Double Roof Hardtop Aluminum Gazebo with Privacy Curtains — a two-tier hardtop with an air gap between the layers, matching privacy curtains, and a rigid metal roof; it pairs with dining sets to form a separate outdoor pavilion beside the pool.

For quieter corners of a garden rather than the pool edge, the Polycarbonate Hardtop Outdoor Swing Bench Collection adds a covered seat in two sizes, with a tilt-adjustable roof, in a perforated metal frame that matches contemporary villa architecture. Because it needs a level pad and clear swing clearance, it belongs on the early layout too.

Bring the inside and the outside into one specification

In a villa or small hotel, the swim spa deck usually transitions through a wet zone into a bathroom and then a bedroom. Coordinating those finishes in the same round of decisions keeps the palette continuous and puts the wet services in one trade package. The engineered oak ranges, such as European Oak Engineered Wood Flooring (2207), carry the floor through from the spa entry into the interior. The same package typically pulls in vanities, basins and toilets, shower systems, decorative wall panels and aluminium ceilings, kitchen cabinetry and wardrobes, together with lighting and site-specific screens.

Buying these as one package is not about bundling for its own sake; it is about a single set of dimensions and a single coordination thread. As one supplier for furniture and building materials, we handle it through our turnkey solutions, with custom and OEM work for non-standard dimensions, finishes and private labelling, logistics and door-to-door delivery, and installation and after-sales support. That single channel matters for a swim spa because the spa, the pergola, the loungers and the paving all have to arrive on the same programme — split orders are where decks stall.

A practical coordination sequence

1. Fix the shell first. Confirm model, configuration, dimensions, pump arrangement and options for the WS-115AⅢ-U, and freeze the swimming-pool scope before the deck is set out.
2. Draw the hard points. Base, power, filtration, drainage, steps and maintenance access go on one drawing, referenced to the same dimensions.
3. Set the finishes. One metal finish, one timber tone, one textile palette across loungers, tables, cabanas, pergola frame and gazebo.
4. Sequence the delivery. Spa shell, structure and furniture planned as one shipment programme so the deck closes once.
5. Inspect with a snag list. Commissioning of the spa, then finish and installation checks on furniture, shade structure and adjacent fit-out.

What to confirm before you order

Three things carry the risk on this specific product. First, the equipment inclusions and electrical requirements of the chosen configuration — the catalogue lists total power, pump counts and options, but the final build is configuration-specific. Second, the availability and compatibility of options such as heat pumps, insulation, sand filtration and steps on the exact model selected. Third, project-level requirements — installation, local rules, and any warranty or response commitments — which should be confirmed for the project rather than read off marketing copy.

Send us the deck layout, the model reference and the target finish palette, and we will confirm the spa configuration, the furniture package and the supporting materials against one dimension set. Enquiries through our SANTERSON website receive a response within 24 hours during business hours (Monday–Saturday, 8:00 AM–6:00 PM GMT+8).
