They look related, but a hot tub and a swim spa answer different questions. One is about heat, hydrotherapy and a nightly ritual; the other is about swimming, play and replacing a pool that only works three months a year. Here is how we help New Brunswick families choose between them — including the honest cases where the answer is 'neither' or 'both'.
TL;DR
- Hot tubs run hotter and are built for relaxation and hydrotherapy; swim spas run cooler and are built for swimming and play.
- A swim spa effectively replaces a backyard pool — and unlike a pool, it works twelve months a year in New Brunswick.
- Hot tubs are smaller, easier to site and cost less to buy and run; swim spas need more space, more power and a bigger budget.
- Dual-zone swim spas offer a real hot tub end and a swim end in one footprint — the family compromise that actually works.
- Both are available with Arctic Spas' salt water system, which simplifies care on either water volume.
Two Different Machines for Two Different Lives
A hot tub holds its water around 37-40°C and is engineered for sitting: sculpted seats, targeted jets, quick heat-up, easy nightly use. A swim spa holds a longer, deeper body of water at a cooler temperature — comfortable for exercise and for kids to actually swim — with a current or open water at one end.
The daily experience differs accordingly. Hot tub ownership is a twenty-minute ritual: soak, unwind, sleep better. Swim spa ownership looks more like pool ownership: afternoon swimming lessons, water games, training sets — plus an evening soak if you choose a dual-zone model.
Space, Siting and Installation
A hot tub fits on a reinforced deck or a modest pad and often tucks close to the back door — which matters in January, when every metre of shovelled path counts. Swim spas are longer and much heavier filled: they need a serious concrete pad, planning for crane access on delivery day, and more clearance. Our guides on pads, bases and delivery costs cover the site-prep details.
Cost of Ownership, Honestly
A swim spa costs meaningfully more than a hot tub to buy, and its larger water volume costs more to heat — though far less than heating an outdoor pool shoulder-season, because a swim spa is insulated like a hot tub, not open to the sky. A hot tub is the lighter commitment on every line: purchase, energy, chemicals and water changes.
The fair comparison for a swim spa is not a hot tub — it is a pool. Against a pool's install, landscaping, fencing, heating and a season that ends in September, the swim spa's twelve-month usefulness changes the math entirely. Our swim spa vs pool article runs that comparison in full.
Which Family Fits Which Machine
Choose a hot tub if your goals sound like: unwinding after work, easing a sore back, couple time, teenagers decompressing, soaking under snowfall. Choose a swim spa if they sound like: kids who would live in the water all summer, lap swimming or aquafit, athletic training, or replacing the pool you wish you had — without giving it up for eight months a year.
The dual-zone models — like Arctic Spas' larger all-weather pools with a separated spa end — genuinely serve both lists: the swim end runs cool for exercise while the spa end runs hot for soaking, each on its own controls.
Winter Performance in New Brunswick
Both machines are built for year-round outdoor use here — if they are built for it. Arctic Spas engineers hot tubs and all-weather pools on the same cold-climate platform: insulated one-piece floor, heat-recovering cabinet, covers rated for Maritime snow, freeze protection, and the salt water option on both. Winter is when the engineering either pays off or gets expensive.
The Decision in One Paragraph
If your honest picture is twenty relaxing minutes most evenings, buy the hot tub — it is cheaper, simpler and you will use it more. If your picture is swimming, active kids and a pool alternative that does not hibernate, buy the swim spa. If it is both and the budget allows, a dual-zone all-weather pool is the one machine that does not ask you to choose. Come try all three configurations in our showrooms.
New Brunswick Perspective
In New Brunswick the swim spa's strongest argument is the calendar: a backyard pool here gives you roughly twelve to fourteen weekends of real use a year, while a swim spa gives you fifty-two. Families who swim year-round tell us the February sessions — snow on the cover lifter, steam over the swim lane — are the ones that make the purchase feel justified.
