Why should I buy a hot tub?
Xavier Labelle“Why should I buy a hot tub?” is one of the most common questions we hear at Canadian Spa Company, and it deserves a more honest answer than a list of vague benefits. A hot tub is a meaningful purchase — both upfront and in ongoing running costs — so the case for one needs to make sense for your lifestyle, your garden and the way you actually spend your evenings. Below are the reasons UK owners most often give us once the spa is in their garden, along with the practical points worth weighing up before you order.
A daily moment of proper relaxation
The single most common feedback we get from new owners is that the spa becomes their “decompression button” at the end of the day. Twenty minutes in warm, jetted water creates a clear break between work and the rest of the evening — a physical signal to slow down. Many owners find their stress levels drop, their shoulders unclench, and they sleep better afterwards. We’re careful not to oversell the wellness side, but the consistent pattern from real customers is that the spa is used far more often than expected, precisely because it works as a daily ritual rather than a once-a-month treat.
Hydrotherapy that may help with everyday aches
Warm water and the buoyancy it provides can ease pressure on joints, and many people find a session in the spa supports tired muscles after exercise, gardening, or a long day on their feet. The adjustable jets in our hot tub range let you target specific areas — lower back, calves, neck and shoulders — at the pressure that suits you. We don’t make medical claims, and a hot tub isn’t a substitute for proper treatment, but a great many owners say their post-soak comfort is one of the reasons they bought a second spa years later.
Better sleep, better mornings
A common UK ritual is the late-evening soak: 15–20 minutes in warm water about an hour before bed. Many owners report that they fall asleep more easily after using the spa, partly because of the wind-down effect and partly because of the natural temperature drop your body experiences after getting out. It isn’t a guarantee — sleep is shaped by lots of factors — but if you’re someone who struggles to switch off in the evening, a hot tub gives you a place to genuinely stop scrolling and sit still.
Time with family and friends
Hot tubs change how you use your garden. They turn the back of the house into a place people actually want to spend time in, including teenagers who otherwise live in their bedrooms. Owners frequently tell us that the spa has become the family catch-up spot — phones get put down (mostly), and the conversations that wouldn’t happen on the sofa happen in the tub. For couples, it’s an obvious date-night setup; for groups, it’s a low-effort way to host without the cleanup of a sit-down meal.
If your household is more “exercise” than “entertaining”, our swim spa range brings the same relaxation benefits with the addition of a swim current and dual-temperature options on selected models — useful for shared households where one person wants a workout and another wants a hot soak.
Year-round value in the UK climate
This is where a UK hot tub earns its keep most clearly. Pools and outdoor saunas are wonderful but heavily seasonal; a properly insulated hot tub is a four-season piece of kit. The best soaks are honestly the cold ones — frosty mornings, snowy evenings, the first proper autumn chill. With a quality fitted cover and modern insulation, running costs stay sensible even in winter, and the spa gets used far more reliably than a paddling pool you only fill up in July.
If you’re buying for a holiday let or Airbnb, the calculation is even more straightforward: a hot tub is one of the strongest filters guests use when searching for a stay, and it can demonstrably push your nightly rate and occupancy. Year-round use also means year-round relevance in listings.
Things worth thinking about before you buy
None of the above means a hot tub is right for everyone. Before ordering it’s worth checking a few practical points:
- Power: our plug & play models run from a standard 13-amp UK socket via an RCD; larger multi-pump spas need a 32-amp hardwired supply installed by a qualified electrician.
- Base: hot tubs need a flat, level, load-bearing base — usually a concrete pad, paving slabs on a sub-base, or an engineered deck.
- Access: measure the route from the road into your garden, including gate widths and any tight corners or steps.
- Running costs: a good cover, modern insulation and sensible scheduling are the main levers. Replacement hot tub covers are usually the most impactful upgrade an older spa can have.
- Maintenance time: 10–15 minutes a week of water testing and chemical balancing, plus a filter rinse and a full water change every 3–4 months. It’s not onerous, but it isn’t zero.
Frequently asked questions
How long does a typical soak last?
Most owners use the spa for 15–30 minutes at a time. Longer isn’t always better — your body keeps absorbing heat the whole time you’re in, so shorter, more frequent sessions tend to be more enjoyable than one marathon dip.
Do hot tubs really help with sleep and recovery?
Many people find a relaxing soak before bed helps them wind down, and warm water with buoyancy may help ease tired muscles. We avoid making medical claims — the honest answer is that lots of owners find these benefits, but how much you experience will depend on you.
Are hot tubs expensive to run in the UK?
Running cost depends on the model, your tariff, the quality of your cover and how cold your local climate is. A well-insulated plug & play spa with a modern cover and predictive heating is meaningfully cheaper to run than people typically expect. Older spas with worn covers are the opposite — the cover is the single biggest factor.
How long do hot tubs last?
Acrylic shells are designed for decades of use; pumps, heaters and control packs are the components that wear and may need replacement over the spa’s life. Regular hot tub servicing keeps everything running well and helps spot small issues before they become expensive ones.
Can children use a hot tub?
Yes, with sensible supervision and shorter, cooler sessions. Many UK families simply set the temperature lower (e.g. 35°C rather than 38°C) when the children are using it, and limit time to 5–10 minutes for younger ones.
What owning a hot tub costs over a year
The purchase price is only part of the picture. These are the regular costs most UK owners should plan for.
| Cost | How often | What drives it |
|---|---|---|
| Electricity | Every month | Your tariff, the cover, the insulation, how hot you keep the water and how often the cover is open |
| Water care chemicals | Ongoing | How many people use it and how often. A complete chemical kit covers the basics |
| Filters | Every 6 to 12 months for hard-shell spas | Heavy use means replacing sooner |
| Water | Every 3 to 4 months | A full drain and refill, plus your water bill if you are metered |
| Cover | Every several years | Sun, weather and how well it is cared for |
| Servicing | As needed | A service visit can catch small faults early |
For electricity, the current Ofgem cap is a useful reference point. You can check the latest unit rate on the Ofgem price cap page and compare it with your own tariff.
What the evidence says about warm water and wellbeing
We are careful here. The NHS recommends regular activity and a good bedtime routine for wellbeing, and a hot tub is not a replacement for either. What it can do is give you a regular place to switch off, and warm water may help tired muscles feel more comfortable. For better sleep habits, see the NHS Every Mind Matters sleep guidance. If you have a heart condition, blood pressure problems or another health condition, speak to your GP before using a hot tub. You should not use a hot tub while pregnant.
Is a hot tub right for you? A quick checklist
- You can picture using it at least two or three times a week, all year round.
- You have a level, solid spot for it, with a route in from the road that you have measured.
- You are happy to spend 10 to 15 minutes a week testing and balancing the water.
- You know whether you want a 13-amp plug and play spa or a 32-amp hardwired model, and have budgeted for an electrician if needed.
- You have thought about who will use it, and how many seats you really need.
If you tick most of these, a hot tub is likely to earn its place. If not, a smaller 2 to 4 person spa or a sauna may suit you better.
Is now a good time of year to buy?
Many people buy in autumn so the spa is ready for the colder months, which is when most owners say they enjoy it most. Lead times and delivery slots vary, so check availability early.
Do I need planning permission?
Usually not for a hot tub in a back garden, but a large shelter or building around it may count as an outbuilding. Check the Planning Portal outbuildings guidance or your local council if you are unsure.
Worth it for the right household
For most UK households that use it regularly, a hot tub repays the investment in lifestyle terms long before it does in any spreadsheet. It’s a daily reason to stop, a place to spend time with the people who matter, and a year-round way to enjoy your garden. If those reasons resonate, browse the Canadian Spa hot tub range or talk to our team about which model fits your space and the way you’d actually use it.
