A square swim spa looks simple on a mood board and complicated on site. Before the first concrete is poured or the first deck board cut, the unit dimensions, the equipment room, the power feed and the access route all have to agree with each other. This guide walks through how we match the Outdoor Swim Spa WS-PC03 with architectural drawings and real site conditions, so the spa arrives to a prepared base instead of a list of problems.

Start From the Envelope, Not the Rendering

The WS-PC03 is one of the more compact layouts in our swim and hydrotherapy range: a 3 m by 3 m footprint with a 1 m shell depth. That square plan is what makes it useful for tight villa terraces, resort podium decks and courtyard villas where a long lap pool would dominate the plot. It also means the setting-out is unforgiving. On a small terrace there is rarely room to shift the unit half a metre once the paving pattern has been laid.

When we receive drawings for a project, the first thing we check is not the spa itself but the space around it. The catalog shell dimensions are only the starting point. Decking returns, coping or edge trim, the clearance needed to open and service the control and pump assemblies, and the working space for lifting the unit into position all sit outside those numbers. We ask architects and contractors to show a clear service zone on plan rather than assuming maintenance happens through a 100 mm gap.

What the Drawings Need to Show Before Production

We build against approved drawings, so the more complete the drawing set, the fewer change orders later. For this type of unit we normally need the following coordinated on one plan:

• Finished floor level of the spa surround and the threshold heights around it, so steps and seating do not block access to the water.
• The base or plinth detail: a fully supported slab or frame that carries the filled weight evenly. Point supports under a 3 m square shell are the most common thing we have to send back for revision.
• Drainage route and an overflow or spill path for the fill and drain cycle, plus where the discharged water actually goes.
• A dedicated electrical run with its isolation located to the requirement of the local regulations that apply on site. Total installed load for this model is 2.75 kW; the circuit size, protective device and bonding arrangement must be set by the project engineer against their own code, not copied from a datasheet.
• The access route from the delivery vehicle to the final position — gate widths, slab load limits overhead, crane or gantry points for upper-level terraces.

Equipment, Options and the Load They Put on the Plant Room

The standard configuration carries one water pump, one filter pump, a jet package of 50 pieces with four water columns, one LED light and ozone sanitisation, controlled from a single control set. That is what the drawings should reflect for water treatment, jet location and lighting positions.

Catalog options shift both the plant space and the electrical demand: heat pumps, UV sterilisation, sand filtration, additional water pumps, insulation and steps are all available, and availability and compatibility vary by model. A heat pump in particular changes the equipment-room ventilation and the noise picture on a shared resort deck, so we want that decision made before the enclosure is detailed rather than after.

Included equipment and electrical requirements should always be confirmed for the exact configuration ordered. Treat catalog figures as a coordination basis, not as an installation instruction.

When the Site Cannot Take the Standard Plan

Not every terrace accepts a standard square. Where the setting-out is irregular — a curved pool edge, an angled courtyard, a spa that has to sit inside a landscaped podium — we look at customized shape outdoor spas instead of forcing the standard plan into an awkward corner. Square, round, oval and curved shells are all possible, which lets the spa follow the architecture rather than dictate it.

Where the brief calls for a longer swimming run alongside the hydrotherapy seat, other models in the swimming pools and swim spas range carry longer shells and an added swim training system. The WS-PC03 is not listed with a swim training system, so projects that need continuous lap swimming should be specified on a longer model from the outset rather than adapted later.

How Our Design Coordination Runs

For project customers we work through the same sequence we apply across furniture and building materials: a project brief and design proposal, then quotation and detail confirmation, then production, shipment and follow-up. On a swim spa that means an early review of your layout drawings, a marked-up set showing our required clearances and plant space back to you, and a frozen specification before manufacturing starts.

Because the spa is usually one line item among many on a villa or hospitality package — outdoor furniture sets, pergolas, wall cladding, bathroom ceramics — coordinating it with the rest of the fit-out avoids the classic clashes: a lounger positioned over the service hatch, a lighting scheme that fights the underwater LED, or paving that cannot be lifted for maintenance.

Delivery and Site Readiness

Freight is arranged by sea, air or rail with the usual export paperwork and door-to-door delivery. What decides whether the delivery day goes smoothly is site readiness: a confirmed base that has cured and been levelled, the electrical run in place and labelled, and a clear path for the lifting operation. We ask for a photo or short site report confirming those three points before the unit ships, which costs nothing and prevents an expensive wait on arrival.

Import terms, duties and delivery scope vary by project, so we settle Incoterms and the handover point in writing with each buyer rather than assuming a standard arrangement.

A Short Checklist for Designers and Contractors

Before the spa is ordered

• Confirm the shell size against finished deck levels, not structural slab levels.
• Fix the option list — heat pump, UV, sand filtration, steps, insulation — and let us reflect it in the drawings.
• Decide recessed or above-deck installation and detail the support accordingly.

Before production starts

• Return an approved drawing set showing clearances, plant space, drainage route and electrical run.
• Confirm jet, light and control positions against seating, handrails and glazing lines.
• Confirm the lifting route and any load limits on slabs or decks along that route.

Before delivery arrives

• Base complete, level and fully supported; drainage tested; electrical run in place with isolation.
• Access path cleared and protected; crane or gantry booked if the unit is going to an upper level.
• Site contact named so installation and inspection can be scheduled on arrival.
