Infrared vs Traditional Sauna: Which Is Right for Your UK Home?
How they differ, what each feels like, and which suits your home, body, and budget.
If you only have two minutes: infrared plugs into a normal socket, warms up in 10 to 15 minutes and feels like sitting in warm sunshine. Traditional is the classic 80 to 100°C Finnish ritual, needs a 32-amp circuit, and pairs naturally with an ice bath. Both genuinely work. The right one is the one that fits your house and your temperament.
Two real options.
Different homes, different bodies.
Both deliver real wellness benefits. They just suit different houses, different temperaments, and different budgets. Here is the honest split.
- Plugs into a standard 13-amp socket, no electrician
- Warms up in 10 to 15 minutes, around 50 to 60°C
- Indoor cabin, spare room, garage, basement, gym
- From £2,995 for an entry-level cabin
- Longer, gentler sessions (30 to 45 minutes is comfortable)
- Dedicated 32-amp circuit (or a wood burner, no electrics)
- 80 to 100°C with löyly steam from water on stones
- From £5,995 for a four-person cabin
- Garden cube or barrel, becomes a feature of the yard
- Pairs naturally with an ice bath for contrast bathing
- Lasts 20 to 30 years with proper maintenance
Traditional heats the air. Infrared heats you.
A traditional sauna heats the air inside the cabin to a high temperature, usually 80 to 100°C. The heater (electric or wood-fired) warms stones, and you can ladle water onto those stones to create bursts of steam. Your body warms up because the air around it is hot.
An infrared sauna does something completely different. Instead of heating the air, infrared panels emit radiant heat that's absorbed directly by your skin and tissues. The air inside an infrared cabin only reaches about 50 to 60°C, much lower than traditional, but the panels warm your body from the surface inward.
The practical consequence: traditional saunas feel intense, atmospheric, and dramatic. The hot air hits your face when you open the door. Infrared cabins feel more like sitting in warm sunshine, gentler, less aggressive on your breathing, easier to stay in for longer sessions. Neither is "better." They're different mechanisms producing different sensations, with different practical demands on your home.
Two genuinely different
sensations.
The difference lands in the first thirty seconds. The only way to know which one suits you is to try both, but here is what each session actually feels like.
Intense, atmospheric, ritual
Preheat for 30 to 45 minutes, undress, sit on a wooden bench. The dry heat catches the back of your throat at first. You ladle water onto the stones and steam (löyly, if you want the Finnish word) rises in a hot wave that briefly intensifies everything. Sessions are 10 to 15 minutes per round with cold breaks in between. You sweat heavily. Many people describe a meditative stillness that's hard to replicate elsewhere.
Calmer, gradual, routine
Step in while it's still warming up, no long preheat. The temperature feels mild for the first few minutes, then your body starts to warm from within. No steam, no humidity to manage, no sense of the air being "hot." Sessions are 30 to 45 minutes. You can read, listen to music, do breathwork. Less of a ritual, more of a routine.
Which one fits
your house and your body.
A few honest decision-points based on what we hear from UK buyers. None of these are deal-breakers on their own, but if three or four point one direction, that's your answer.
Indoor, plug-in, lower-intensity
No 32-amp supply available; you want to install indoors (spare room, garage, basement); you're new to sauna and 100°C heat is intimidating; you have low blood pressure or find very hot environments uncomfortable; you want shorter, more frequent sessions; you're working with a tighter budget; you want something you can use without committing to a 45-minute preheat.
Outdoor, ritual-led, built to last
You want a garden installation that becomes a feature of your space; the Finnish ritual (high heat, steam, cold breaks) is what you're after; you'll be using it socially with two or more people regularly; you have the electrical capacity (or you're willing to add it); you like the idea of contrast therapy with an ice bath; you want something that lasts decades and develops character with age.
Recovery, sleep, habit
You want better sleep, better recovery from training, and reduced muscle soreness; both have decent evidence behind them. You want a wellness habit you'll actually maintain; both can deliver that, the question is just which one fits your house and your temperament. The "best" sauna is the one you'll step into three or four times a week.
The electrical question is more important than people realise.
This is genuinely the dividing line for many UK buyers, and most sauna retailers don't talk about it clearly enough. A traditional sauna with a 6 to 9 kW electric heater needs a dedicated 32-amp hardwired connection from your consumer unit, fitted by an electrician. If one doesn't already reach the install spot, budget roughly £400 to £1,500 on top, depending on cable run and whether your consumer unit has spare capacity.
A wood burner sidesteps the 32-amp circuit altogether, but trades it for different jobs: a flue installation, fire-safety clearances, building-control sign-off in some areas, and an ongoing supply of dry logs. The most authentic heat, and the most hands-on to run.
An infrared cabin under about 2.5 kW plugs into a normal 13-amp socket. No electrician, no consumer-unit work, no trenching: you move it in, plug it in, switch it on. For many UK homes, especially retrofits and rentals, that's the difference between "yes I can have a sauna" and "no I can't." It's the single biggest reason infrared outsells traditional here, despite traditional being the "purer" experience.
Both can be
indoor or outdoor.
A common myth: infrared is indoor only, traditional is outdoor only. Not true. The choice of location often happens before the choice of type, and that's where most buyers go wrong, they decide "I want a garden sauna" and then assume that means traditional.
A large outbuilding or garden room
The rarer combo. A cube or barrel cabin can sit under cover if the space is big enough, properly ventilated and has a 32-amp supply, think a converted outbuilding or a garden room, not a spare bedroom. Most people choose this look for the garden instead.
A spare room or wellness corner
Any spare room, a corner of a master bathroom, or a home office that doubles as a wellness space. 13-amp socket, no ventilation work.
A dedicated garden cabin
A Nordic-style cube or barrel that becomes a visible part of your landscape design. The classic wellness yard pairing.
Garden use without rewiring
Weather-protected outdoor cabin. Works for buyers who want garden use but have no 32-amp option and don't want to disturb existing landscaping.
Both have research. The cohort data is on traditional.
Traditional sauna research is older and broader. The often-cited Finnish studies (notably from the University of Eastern Finland) show that frequent traditional sauna use is associated with reduced cardiovascular mortality, lower blood pressure, and improved heart-rate variability. These studies looked at people using high-heat traditional saunas two to seven times per week over decades.
Infrared sauna research is newer and more focused on specific markers, skin temperature, peripheral vasodilation, muscle recovery, and certain inflammation markers. The evidence base is smaller but growing, and the lower temperature makes infrared more accessible for people who can't tolerate traditional heat.
Honest summary: if you'll actually use it regularly, both types deliver real wellness benefits. The "best" sauna is the one you'll step into three or four times a week, not the one with the most impressive technical specs. We dig into the research in more detail on the Sauna Science page.
Build-quality signals,
in either type.
If the retailer can't tell you what wood the cabin is built from or what gauge the insulation is, that's a warning sign in either category.
- Wood species
- Thermo-treated or Nordic-grown spruce, cedar, or hemlock. These handle heat and humidity well and develop character over time. Avoid pine for traditional, it releases sap at high temperatures.
- Wall thickness
- Solid wood construction (not veneered panels), ideally 38 to 40 mm thick for outdoor cabins. Visible insulation in the walls and ceiling directly affects running cost and heat-up time.
- Glass + fittings
- Tempered safety glass for any doors or windows. Stainless steel or hardwood fittings for benches, handles, and headrests, not plated plastic.
- Warranty
- A manufacturer warranty you can read before you buy, covering both the heater (the part most likely to need attention first) and the cabin structure. Across our Hekla range that's a 2-year manufacturer warranty on the cabin and the heater.

Running costs vary by usage frequency, insulation quality, and your electricity tariff. The rough rule: infrared sessions cost a small fraction of traditional sessions, primarily because they don't need a 30 to 45 minute preheat. Browse our full sauna range for specs and current pricing.

What we'd actually
recommend.
If you asked us which one we'd recommend for the average UK buyer with no strong preference yet, here is what we'd say.
Start with an indoor infrared cabin
For a typical UK home and budget, it's the version you'll actually use. No electrician, no preheat, no commitment beyond ten minutes when you fancy it. The number of "outdoor traditional saunas in British gardens" that get used twice and then become expensive sheds is genuinely high.
Go traditional, outdoor
For someone building a wellness yard from scratch, with the space and the budget for a proper garden installation, an outdoor cube or barrel sauna paired with an ice bath is the closest you'll get to a true Nordic bathing experience without flying to Helsinki. It's where contrast therapy genuinely shines.
There's no wrong answer
Pick the one whose practicalities match your house and whose experience appeals to you more. You can always upgrade later. If you want help thinking through what would suit your specific home, the Build Your Yard configurator walks you through space, budget, and use case in about three minutes.
A sauna is one half
of the cycle.
Heat opens the body up; cold closes it down. Alternating the two, the Nordic kontrastbad, is where the deepest recovery sits. A sauna pairs naturally with a cold plunge and a warm soak, and the Build Your Yard bundle brings all three together for a saving that scales with the set.
Pair it with an ice bath
Step straight from the heat into a steady 3°C plunge. The hot-then-cold contrast is the part most owners say they feel the next morning. Our Chill Tubs range runs from a normal 13-amp socket, no buckets of ice required. Browse ice baths.
Pair it with a hot tub
Gentler than a sauna and far more social, a hot tub gives you warm hydrotherapy at 37 to 39°C any night of the week. It is the easiest of the three to use daily, and the natural centrepiece of the yard. Browse hot tubs.
What people ask us
before they decide.
Is infrared better than traditional?
Neither is universally better. Infrared is more practical for most UK homes, plug-in, lower temperature, shorter sessions. Traditional is more authentic if you want the Finnish ritual of high heat and steam. The "better" one is the one you'll actually use consistently.
Can I have a sauna without rewiring my house?
Yes, most infrared cabins under 2.5 kW plug into a standard 13-amp socket. Traditional saunas with electric heaters generally need a dedicated 32-amp hardwired connection, which usually means hiring an electrician.
Which type is better for sore muscles and recovery?
Both deliver recovery benefits through increased circulation and heat-shock protein response. Traditional's higher temperatures may produce a stronger acute response, but infrared's longer sessions can deliver similar total heat exposure. For most users, the difference is marginal, pick the one you'll use most often.
Do I need planning permission for a garden sauna in the UK?
Most garden saunas fall under permitted development, but rules vary by size, height, distance from boundaries, and whether your property is listed or in a conservation area. Always check with your local planning authority before installation. We can advise on this before you order.
How long do saunas last?
A well-built infrared cabin typically lasts 10 to 15 years with proper care. A well-built outdoor traditional sauna, properly maintained, can last 20 to 30 years, the heater might need replacing once or twice in that time.
Can I use my sauna every day?
Yes, for both types. Most regular users do three to five sessions per week. Hydrate well before and after, listen to your body, and consult your GP if you have cardiovascular conditions, are pregnant, or take medication that affects heat tolerance.
Infrared or traditional for weight loss?
Neither sauna will produce meaningful long-term weight loss on its own, what you see on the scale after a session is water weight that returns when you rehydrate. Saunas are best thought of as recovery, wellness, and habit tools, not weight-loss tools.
A sauna only delivers its benefits
if it gets used.
We stock both infrared cabins and traditional cubes and barrels, all with white-glove delivery and a manufacturer warranty as standard. The right one for you is the one that fits your home, your routine, and your honest expectations, not necessarily the most impressive on paper.
