A swim spa that works on day one is rarely the result of a good guess about the garden. It is the output of an installation plan agreed before the shell leaves the factory — dimensions, sub-base, power, access and service clearance all recorded on the same sheet. Using the Outdoor Swim Spa WS-S38 as the worked example below, this article walks through what a complete plan should contain, and which items have to be settled at quotation stage rather than on site.

1. Site dimensions, access route and sub-base

Start with the footprint of the unit and then add working space around it. The WS-S38 is catalogued at 3760 × 2080 × 1110 mm, so the plan should show three separate measurements: the spa outline, the finished plinth or slab it sits on, and the clear path from the delivery vehicle to that position. A compact swim spa often fails on the last of these — side gates, steps, soft landscaping and overhead wires routinely block a crate that easily fits the final position.

  • Record finished level heights at the installation point, not just the plan view. The base must be level in both directions before the shell is set down.
  • Show the sub-base build-up: compacted hardcore, lean-mix screed or a reinforced concrete slab, with the load of a full spa plus bathers carried by the slab and not by the surrounding paving.
  • Note drainage falls away from the plinth, and confirm that no irrigation line, gas pipe or existing footing sits under the footprint.
  • Specify the finish that will butt up to the cabinet — timber deck, stone coping or tiles — and whether an overflow or skimmer arrangement is required with that finish.

2. Power supply, circuit sizing and protection

Total power for this configuration is listed at 14.05 kW, which puts the spa firmly in the dedicated-circuit category rather than a plug-and-play one. The plan should carry the supply details your electrician needs: the incoming voltage and phase arrangement available at the property, the cable route and its length from the meter or distribution board, and the location of an isolator that stays reachable in an emergency.

  • Cable size and breaker rating are set by the actual supply arrangement and run length, so they belong on the electrician's schedule — not copied from a datasheet. Send the equipment list with the total connected load and let the local contractor sign off the circuit.
  • Include residual-current protection and earthing details as specified by your local wiring rules; the plan should name the responsible electrical contractor before delivery is booked.
  • Decide now whether a heat pump will be added later. Heating changes the load profile, and pulling a second cable through finished paving is expensive.
  • Plan a small weatherproof control niche close to the cabinet. The spa is controlled from 1 control set, and it needs a dry, accessible position that is still within reach from the deck.

3. Equipment included in the selected configuration

Half of all installation disputes come from an equipment list nobody compared with the quotation. Cross-check every item against your order, and mark anything that is optional rather than fitted. For the WS-S38, the catalogue lists 3 water pumps, 1 filter pump, 51 jets together with 6 water columns, 4 LED lights plus 12 small LED lights, and a waterfall feature; features shown are water jets, LED lighting, ozone and waterfall.

Note that a swim training system is not listed for this model. If lap swimming matters to the buyer, that requirement should be resolved at selection stage — Swimming Pools and Swim Spas covers configurations that do include a swim training system, and switching after the sub-base is poured usually means moving the whole footprint.

4. Access for maintenance and future service

A plan that only shows the spa sitting beautifully is incomplete. Every pump, filter, control set and light has to be reached without lifting the unit off its base. Leave an access panel or removable deck section aligned with the equipment side, and keep the filter pump position clear of planters and furniture.

  • Mark on the drawing where a technician can stand, kneel and remove a pump — 51 jets and 6 water columns mean several circuits to trace.
  • Confirm the ozone system's service point and keep ventilation to the cabinet void unobstructed.
  • Photograph the as-built plant room or cabinet void before the finishes go on, and file those images with the handover pack.

5. Optional accessories — decide them at quotation stage

Catalogue-listed options for this range include control systems, UV sterilisation, water pumps, heat pumps, sand filtration, insulation and steps. Availability and compatibility vary by model, so each option needs written confirmation against the specific unit ordered. The reason it belongs in the plan is physical: insulation wraps the shell, a heat pump needs its own position and condensate route, sand filtration needs space and a valve access, and steps change the deck level you are trying to align with.

SurroundsDeck or paving finish, coping detail, drainage falls, position of sun loungers, pergola and storage around the splash zone

6. Delivery, coordination and after handover

With a villa or resort package, the spa rarely arrives alone. Poolside loungers, pergolas, outdoor dining sets and paving all compete for the same slab and the same programme week. Our logistics and door-to-door delivery service covers freight forwarding, packaging and container loading, customs paperwork and tracking, so the delivery date in the plan should match the container booking rather than an assumed lead time. Import terms, duties and transit times are confirmed case by case with the project team.

After the unit lands, installation and after-sales support covers on-site installation, inspection and snag lists, warranty coverage, spare parts and ongoing maintenance. Practical response arrangements and warranty terms for a specific project are confirmed in the contract documents, so keep the signed equipment list with them — it is the reference both sides use when a spare part or a service visit is requested.

Before production starts, ask for one combined drawing that shows the spa outline, the sub-base, the electrical schedule and the access panels. If any of those four is missing from your pack, the plan is not finished yet.
