Two pumps, faster heat, deeper massage. Worth the sparky.

Honest test: do you specifically want a two-pump tub, 5HP continuous-duty pumps, or 5+ seat capacity? If yes to any, 32A is the right tier — the pump HP needed simply doesn’t fit a 13A budget. If your routine use is one to three adults and you don’t need diversion or 5HP pumps, the 13A plug-and-play range is the cleaner answer — same Balboa BP control, same Mountain Pure™ UV-C plus ozone, same 5″→3″ cover, no electrician needed.

Three concrete things. (1) Pump HP — 5HP continuous-duty pumps drawing 15.2A each are physically possible on 32A and not on 13A. (2) Three pump architectures — single-pump (Winnipeg, Cambridge) for social soaking with a left-right diverter; two-pump (Erie SE, London SE, Toronto UV, Thunder Bay, Victoria, Alberta, Kingston) for full power per side; two-pump + per-side diverters (Vancouver UV, Niagara) for focused chiropractor-class pressure into a single quarter of the tub. (3) A 3kW heater vs 2kW, which on bigger water volumes recovers temperature noticeably faster between sessions.

What 32A doesn’t buy you: better insulation, a thicker cover, a different control system, or lower per-day running cost. Build spec is identical across the range.

Typically £300–£700 for the spa circuit itself — a dedicated run from the consumer unit, RCD-protected, terminated at a rotary isolator within reach of the spa. Variation is mostly cable run length and consumer-unit status. If the property’s consumer unit is at capacity (usually older 1990s-or-earlier units), expect a separate £400–£800 for a board upgrade. Get a sparky out for a 30-minute site visit before ordering the spa — better to know the real number up front.

Depends which delivery option you’ve chosen. If you’ve ordered our install service, the cable needs to be in place at the spa pad on the day we arrive — coiled with 4–5m spare and the end stripped back, ready to take into the spa. Our installers will make a temporary connection to power the spa up and walk you through chemicals and use, then your electrician returns afterwards to sign the install off properly. With kerbside delivery, there’s no deadline — the spa is dropped at the kerb and your electrician can run the cable into it any time after it’s in position. We’ll guide them through the connection over the phone if they need anything.

A 32A breaker in the consumer unit, RCD-protected, feeding a rotary isolator outdoors. From the isolator, a 6mm armoured cable runs as a tail to just outside the spa’s footprint — not underneath (the cable enters the spa from a side cabinet panel, not the base). Leave 4–5m of spare cable coiled by the pad, end stripped back and electrical-taped, with live, neutral and earth ready to land in the spa’s terminals. If your electrician’s calculation calls for a different cable size based on your distance from source or other circumstances, that’s fine from the spa’s perspective — provided the spa receives the full 32A, the three conductors are present, and the circuit is RCD-protected. Note on timing: with our install service the cable needs to be ready and coiled at the spa pad on the day we arrive (we’ll make a temporary connection to power up and demo the spa, then your electrician returns to sign off). With kerbside delivery there’s no deadline — your electrician can wire it in any time after the spa is in position.

Marginally on like-for-like volume, but mostly the heat-up times work out about the same because 32A tubs hold more water. A 32A tub runs a 3kW heater vs 2kW on 13A; the bigger heater handles the bigger volume in roughly the same time. Cold mains-fill to 38°C is 14–24 hours on either tier depending on water volume and ambient temperature. Once at setpoint, the heater cycles to hold — only a few hours of actual heater-on time per day in average conditions.

No. The amperage isn’t a recommendation — it’s a hard limit. A 5HP pump pulling 15.2A on a 13A circuit either trips the breaker on startup or melts the cable if the breaker doesn’t trip first. Tubs designed for 32A genuinely need 32A. If 32A install is unworkable on the property, the 13A plug-and-play range is engineered for that constraint — different pump HP, different model lineup.

Per-product warranty terms vary; full details on each product listing. UK service is handled from our Redhill, Surrey office — same team that handles the 13A and patio ranges. On any tub at this tier we’d flag that keeping up with filter changes and water chemistry is the fastest way to invalidate a pump warranty: more water through more jets means more filter load, and ignoring it isn’t a position any pump manufacturer covers.

Yes — practically not optional. The 5″→3″ tapered hard-top cover weighs 30–40kg+ on a 5/6-seat tub, more on a 7-seat. That’s a genuinely awkward object to wrestle off the tub twice a day, especially in wind, rain or cold weather when the cover’s picked up surface water. A cover lifter is £300–£600 and is the difference between a tub you use every evening and a tub you don’t because dealing with the cover is too much effort. Budget for it in the original quote.

A level, load-bearing 3.5 × 3.5m minimum — closer to 4 × 4m for the bigger 7-seat models or any tub that needs a cover-lifter swing. Existing patio is fine if rated for 2.5–3 tonnes filled weight; concrete pad if not. The acrylic shell tolerates around 2″ of slope variation over the spa’s length — no laser-levelling needed. Don’t drop on grass (uneven settlement stresses the corners and voids the warranty). Existing decking only works if explicitly engineered for the load.

Most tubs in the range ship from UK stock in 1–2 weeks, faster if you’re flexible on delivery date. If you’ve ordered our install service, time the electrician’s circuit work to be ready for the day we arrive (cable coiled at the spa pad, end stripped). With kerbside delivery there’s no deadline — the electrician can come whenever suits after the spa is in position. Some larger or seasonal-demand models can run longer; per-product lead times shown on each listing.

Tubs at this size run 220–245cm wide — a standard garden gate (800–900mm) won’t fit them. You need a 1,000mm+ clear passage from kerb to final position, including any turns. If access is tight, an over-the-fence crane lift is the usual solution — typically £400–£800 depending on reach and overhead complexity. Before ordering, measure the narrowest point of the route and compare to the spa’s exact width on the product listing. We’ll flag any access issue at the order stage.
