Start from the footprint, not the brochure

The catalog dimensions for this model are 5500 × 2300 × 1350 mm. Treat that number as the minimum envelope, then add three clearances on your own drawing before you count a single lounger:

• Circulation. Deck space in front of the entry step and along the long side, so users can enter wet-footed without stepping over planted beds or furniture.
• Plant and service access. Room for a technician to reach the equipment compartment, open it fully and lift a pump out without moving furniture.
• Delivery route. The path from the truck to the pad, including gate widths, turning radii and any overhead obstruction. A spa that fits the pad but not the gate becomes a crane problem.

Send that marked-up drawing with your enquiry rather than just the model name. It is what lets the factory and your site team argue about the same thing at the same time.

What the catalog lists for WS-125AⅣ-U

These are the figures shown on the product page. They matter because they drive two quantities people usually leave to the end: electrical supply and plant-room space.

The catalog does not list a swim training system for this variant. If the client brief calls for counter-current swimming, raise it at quotation stage: the same 5500 mm shell is offered with a listed swim training system under the WS-125AⅣ entry, together with a different pump and jet count. Confirming which variant you are buying changes the electrical load as well as the use case.

Options that change both price and the works around the spa

The catalog lists control systems, UV sterilization, water pumps, heat pumps, sand filtration, insulation and steps as options. Each one is a decision with a site consequence:

• Heat pump. Adds an outdoor mechanical unit — pad area, its position relative to neighbouring windows, and its own supply.
• Insulation. Affects how the spa holds heat between sessions and how much heating energy a shoulder-season installation needs.
• Sand filtration. Needs its own position, backwash drainage and a route to the drain.
• UV sterilization and ozone. Reduce how much chemistry the operator handles day to day; check storage and dosing routine with your maintenance team.
• Steps. Fix where people enter, which fixes your paving layout and handrail detail.

Decide these before you order the surrounding products. A heat pump or sand filter added after the paving is laid means lifting finished work.

Counting the poolside furniture around it

The spa is one line on a swimming pools and swim spas order; the deck furniture is a separate quantity exercise, and it should be counted from the same drawing. For a hotel, resort or villa pool deck, work through these groups:

• Loungers. Count by peak concurrent users, then subtract seats shaded by a structure. Our Aluminum Sling Sun Lounger Collection comes in static sled-base, wheeled and folding versions — the wheeled and folding options let a tight deck flex between high and low occupancy days.
• Shade. One shelter per seating cluster. A Double Roof Hardtop Aluminum Gazebo with Privacy Curtains gives a fixed, all-weather footprint you can set out on the drawing; its dimensions, frame finish and curtain colour are adjustable to project requirements.
• Side tables and storage. One per two loungers as a working rule, plus lockers or a towel station sized to the same user count.
• Wet-zone finishes. Paving, flooring and wall cladding within splash distance are chosen for slip and moisture behaviour, not just appearance.

Order spa and deck furniture against one drawing and you get consistent aluminium finishes, cushion colours and timber tones across the zone. Order them from two different suppliers and you reconcile mismatched tones after installation, which is when these jobs get expensive.

Coordinating the supporting trades

A swim spa sits at the meeting point of several scopes. Put each of these on one coordination sheet with a named owner:

• Structural. Pad and, for a raised or partially recessed installation, the retaining edges and access cover.
• Electrical. Supply capacity against the listed total power, dedicated circuits, protective devices, and lighting that does not glare off the water into habitable rooms.
• Plumbing and drainage. Fill supply, overflow, backwash route, and an emergency drain path away from the pad.
• Water treatment. Ozone is listed as a feature; decide chemical storage, testing routine and who services it during handover.
• Adjacent interiors. The changing and shower area right outside the deck should be specified in the same batch — digital display rain shower systems, basins, vanities and towel warmers from the same sanitary range keep the finishes consistent across indoor and outdoor.
• Interior fit-out link. Where the spa serves a villa or hotel wing, engineered wood flooring, wall panels and joinery in the adjoining rooms should be on the same schedule so colour and threshold details resolve once.

Build one bill of quantities, not four purchase orders

Group the whole package in a single list with columns for quantity, dimension, required-on-site date and trade owner. A typical outdoor swim spa package splits into:

• The spa unit plus its selected options (heat pump, insulation, sand filtration, UV, steps, extra pumps).
• Poolside furniture: loungers, gazebo or pergola, dining and lounge seating from the outdoor furniture range.
• Wet-zone finishes: paving, flooring, cladding, ceiling panels where there is a covered area.
• Bathroom and changing fixtures for the adjacent interior.
• Spares: pump and jet components, filters, consumables, plus a documented water-treatment routine.

Buying that list through one one-stop furniture and building materials supplier gives you a single specification owner for the zone. Where the spa is part of a larger build, our turnkey interior project solutions cover design consultation and space planning, material selection and product specification, manufacturing and quality control, project management and site coordination, then installation and handover. If the 5500 mm envelope is too long for the plot, our range also includes shorter shells such as Outdoor Swim Spa WS-115AⅣ and hydrotherapy spas with massage jets, LED and water features; change the shell and every quantity above changes with it.

Logistics: sequence the delivery to the pad, not to the dock

Freight for a spa is not the same exercise as freight for cartons of furniture. Confirm with your logistics and door-to-door delivery plan:

• Which items travel by sea, air or rail, and which arrive together. The spa and its options should land before the trades that install them.
• Packaging and container loading for the shell, and who unloads it — a spa needs lifting gear on the day, not a pallet jack.
• Customs paperwork in advance: commercial invoices, packing lists and certificates of origin. Gaps here are what strand a unit at the port while the pad sits finished.
• Storage on site between delivery and installation, and who holds the keys to the equipment compartment.

Import terms, duties and transit times differ per shipment and destination. Get them confirmed for your specific consignment instead of assuming a standard arrangement.

Commissioning and after-sales: close the loop with numbers

At handover, the installer should be handed a record that matches what was ordered: model designation, jet count, pump count, control system, fitted options, total power as wired, and the water-treatment regime. Then book installation and after-sales support items — inspection and snag list, warranty scope, spare parts availability and a maintenance plan — while the unit is still under the project team, not after it has been handed to facilities.

Warranty terms, response times and installer availability vary by region and by configuration. Read them against your own contract before you promise anything to an end client.
