Infrared Sauna vs Traditional Sauna: Which Is Better for Home Use in the UK?

A home sauna can turn a spare corner of the house or a garden room into a dependable recovery and switch-off space. The tricky part is choosing the right type, because the experience, installation, and ongoing costs vary more than most buyers expect.

Infrared vs traditional saunas for UK homes: a practical comparison

When people search infrared sauna vs traditional sauna, they are often comparing two very different heating systems that happen to share the same end goal: making you warm enough to relax, sweat, and reset. If you are buying in the UK, day to day realities like electricity prices, compact room sizes, and ventilation in older housing stock matter just as much as the health claims.

How each sauna creates heat (and why it feels different)

A traditional sauna (often called Finnish-style) heats the air in the cabin using an electric heater and heated stones (or, less commonly in the UK, a wood-burning stove). The room gets hot first, then your body.

An infrared sauna uses electrically powered infrared panels that emit radiant heat. You feel warmth directly on your skin and into superficial tissues, even though the air temperature is lower.

That difference in mechanism explains many of the real-world trade-offs:

• Traditional saunas tend to feel intense, enveloping, and “spa-like”.
• Infrared saunas tend to feel gentler, more targeted, and easier to sit in for longer.

Sauna comparison table (UK home focus)

The table below is a good “at a glance” guide for anyone weighing up an infrared sauna UK purchase against a traditional sauna UK setup.

Feature	Infrared sauna (typical home cabin)	Traditional sauna (typical home cabin)
Heat type	Radiant heat from infrared panels warms the body directly	Heated air and stones warm the whole room
Typical temperature	About 45 to 65°C	About 70 to 90°C (sometimes higher)
Warm-up time	Often 10 to 15 minutes	Often 30 to 45 minutes
Humidity	Very dry (no steam function)	Dry by default, steam bursts possible by adding water to stones
Electrical load	Often 1.5 to 3 kW (small cabins may use a 13A plug)	Commonly 6 to 9 kW (usually hardwired on a dedicated circuit)
Running costs (rough UK example)	Lower, often tens of pence per session depending on time and tariff	Higher, often pounds per session due to higher kW and longer warm-up
Installation	Usually modular, lighter requirements	More “built” feel, ventilation and electrical work often more involved
Maintenance	Wipe down surfaces, keep dry, occasional checks of panels and controls	Wipe down, keep dry, stones may need checking and replacement over time
Best fit for	Smaller spaces, frequent short sessions, heat-sensitive users	Those who want the classic high-heat ritual and steam option

The experience: what it’s like to use each type

Traditional saunas bring a distinctive “wall of heat” sensation once the cabin is up to temperature, contributing to longevity through improved circulation and stress reduction. Breathing feels warmer, sweat starts quickly, and short rounds (often 10 to 20 minutes) suit many people. If you like the ritual of ladling water onto stones for a hiss of steam, traditional is the only route.

Infrared sessions usually start more quietly, and they often excel in energy efficiency compared to traditional saunas. The air can feel comfortable, even a little mild at first, then the heat builds on the body. Many owners sit for 30 to 45 minutes because it is easier to tolerate, especially if you are using it for recovery after training or as a wind-down routine.

Both types of saunas offer numerous benefits depending on individual needs and preferences. Traditional saunas can contribute to improving circulation, reducing stress, and offering a classic sauna experience with the option of steam for those who enjoy the ritualistic aspect. Infrared saunas, on the other hand, are known for their soothing, energy-efficient approach, making them ideal for longer, more frequent sessions that gently warm the body and aid in muscle recovery. These benefits can greatly enhance your wellness routine and support overall health when used regularly.

Space and seating also shape the experience. A compact one or two person infrared sauna cabin can work well in a utility room or spare bedroom. Traditional cabins tend to feel more “room-like” and often work best when you can dedicate a proper footprint and ventilation plan.

Benefits: muscle recovery, stress relief, sleep, and “detox”

Both sauna types can support wellness, offer health benefits, and aid in the detoxification process, but it helps to be clear about what is realistic.

Muscle recovery and post-training comfort

If your priority is recovery, infrared often appeals because you can stay in longer at a lower air temperature. Many active users like it after strength training or running because it feels less punishing while still delivering a deep, warming effect.

Traditional sauna heat can also relax muscles and may feel invigorating, supporting cardiovascular health, but the higher temperatures and precise temperature settings can be a lot straight after a hard session, especially if you already feel depleted.

Stress relief and switching off

Either type, when combined with relaxation techniques, can be a powerful decompression tool. The biggest driver is consistency: a sauna you can use three or four times a week is likely to do more for stress levels than the “perfect” sauna you use once a month.

Traditional saunas suit people who love the classic ritual, the contrast of hot and cool, and the immersive sauna experience that provides a sense of leaving the outside world behind. Infrared suits people who want a calmer, more controllable environment, sometimes incorporating therapy activities like reading, breathwork, or a longer sit.

Sleep support

Many people report better sleep after evening sauna use, often because the relaxation and the cool-down afterwards nudge the body towards rest. Infrared saunas can be easier close to bedtime if you find very high heat overstimulating. Traditional sauna can still work well, but timing matters. If you leave it too late and finish overheated, you may feel wired rather than drowsy.

Detox claims (keep expectations grounded)

Sweating is a normal process and can feel cleansing, but “detox” is routinely overstated. The liver and kidneys do the heavy lifting. A sauna can support a healthy routine and offers various health benefits, but it is not a shortcut for lifestyle, nutrition, hydration, or medical care.

UK-specific considerations that often decide the purchase

Choosing the best sauna for home use in Britain often comes down to the practicalities below, not just preference.

Space in typical UK homes

Many UK homes are space-efficient, and even larger houses may not have an obvious sauna-ready room. Infrared cabins generally win here because they come in slimmer footprints and can sit on a flat floor without major building work.

Traditional saunas can still work indoors, but they are easier when you can allocate a dedicated area, manage ventilation, and accept the larger heater clearance needs.

Electricity costs and running costs

UK electricity is expensive compared with many markets. That makes the power draw meaningful over months of regular use. Infrared units tend to consume less because they run at lower temperatures and often at lower wattage. Traditional electric heaters draw more power and also need longer warm-up.

If you expect frequent use, it is worth doing a simple estimate using your tariff (pence per kWh) and the sauna’s kW rating.

Installation, electrics, and compliance

A key divider in the infrared sauna vs traditional sauna debate is the electrical requirement.

Infrared models, especially one to two person cabins, are often designed to run from a standard 13A socket. Traditional saunas commonly require a dedicated hardwired circuit and a suitably rated isolator switch. In UK terms, any new circuit or significant electrical work should be done by a qualified electrician and comply with Building Regulations (Part P) and BS 7671.

Ventilation and moisture in a damp climate

The UK’s damp climate and the way many homes are insulated means moisture control matters. Traditional saunas can create bursts of humidity if you use steam, and that moisture needs a route out. Infrared saunas are typically drier, which can be easier on the building fabric, though you still need airflow to dry the cabin after use.

If you are installing indoors, plan for:

• an air gap and ventilation path,
• surfaces that can cope with heat,
• a routine of leaving the door open after sessions to let moisture escape.

Outdoor options and planning

Garden saunas are popular, especially when indoor space is limited. Planning rules vary, and “permitted development” depends on size, height, and placement, so it is wise to check before you order a large outdoor cabin. Traditional outdoor saunas can be brilliant, but they still need safe electrics and weatherproofing. Infrared outdoor cabins exist too, though they are less common and still need a dry, protected environment for electronics.

Pros and cons of each type (quick and honest)

A balanced sauna comparison should admit that both types are excellent when matched to the right home and user.

After considering installation and day to day use, most buyers land on these trade-offs:

• Infrared pros: Lower running costs, faster warm-up, easier for frequent sessions
• Infrared cons: No steam experience, lower maximum heat, some people miss the “classic sauna” feel
• Traditional pros: Authentic high-heat ritual, steam bursts possible, strong “whole-room” ambience
• Traditional cons: Higher electrical demand, longer warm-up, ventilation and moisture control can be more demanding indoors

Who infrared is best for (UK home profiles)

An infrared sauna tends to suit a broad slice of UK households because it plays nicely with modern routines and limited space. It is often the more practical choice if you want a sauna you will actually use regularly.

Infrared is a strong match for:

• Flats and smaller houses
• People who want 30 to 45 minute sessions at moderate heat
• Frequent users focused on muscle recovery and relaxation
• Households watching electricity spend closely

Who traditional is best for (and when it’s worth the extra work)

Traditional is still the benchmark experience. If you grew up loving spa saunas, or you want the ability to add steam, nothing else quite scratches that itch.

Traditional often fits best when you have:

• A dedicated indoor space, or a well-planned garden installation
• The budget and appetite for proper electrical work and ventilation
• A preference for shorter, hotter rounds
• A desire for the ritual: warm-up, steam, cool-down, repeat

A simple buying checklist before you order

The easiest way to choose the best sauna for home use is to decide what will make you use it consistently, then work backwards to the model and installation.

Before you commit, check these essentials:

1. Space and access: Measure the footprint, height, and the route into the room (doors, stairs, tight corners).
2. Power and electrics: Confirm kW rating, plug-in vs hardwired, and whether a dedicated circuit is recommended.
3. Ventilation plan: Decide how the cabin will dry out after use, especially for traditional setups.
4. Running cost estimate: Multiply the sauna’s kW by session length (hours), then by your electricity unit rate.
5. Your main goal: Recovery, stress relief, sleep routine, or the classic sauna ritual. Pick the sauna that best supports that goal.

Internal linking opportunity: Retailers like Your Fitness Hub often publish sizing charts, electrical notes, and “what fits where” guidance within their home sauna UK category pages, which can help you avoid common installation surprises.

FAQ: common UK buyer questions

Do infrared saunas cost less to run in the UK?

Usually, yes. Infrared cabins commonly use lower wattage and need less warm-up time, so the kWh per session is often lower. Your exact cost depends on your tariff and how long you sit in.

Can I plug an infrared sauna into a normal socket?

Many one to two person infrared cabins are designed for a standard 13A plug, though a dedicated socket and sensible load management is still wise. Larger infrared models may need hardwiring. Always follow the manufacturer’s requirements and use a qualified electrician if there is any doubt.

Does a traditional sauna always need special wiring?

In most home installations, yes. Traditional heaters are commonly 6 to 9 kW and are usually hardwired on a dedicated circuit. That is one reason traditional saunas can be more complex to install in a typical UK property.

Which is better for muscle recovery, infrared or traditional?

If you want longer, gentler heat after training, infrared often feels easier and is popular for recovery routines, offering additional health benefits. Traditional can still help with relaxation and circulation, but the higher heat can be less comfortable immediately post-workout for some people.

Which is better for stress relief and sleep?

Both can help. Infrared can suit evening use if you prefer a calmer, lower temperature session. Traditional suits those who love a more intense heat and a clear hot-cool ritual. In either case, leave time to cool down before bed.

Do saunas really “detox” the body?

They make you sweat, which can feel cleansing, but detox claims are often exaggerated. Think of sauna use as support for relaxation, recovery, and habit building, not a replacement for the body’s normal detox processes or medical advice.

Is infrared safer than traditional?

Infrared is lower temperature, which some people find easier to tolerate, but both involve heat stress. Safety comes from sensible session length, hydration, and correct installation. If you are pregnant, have cardiovascular concerns, or feel unwell with heat, seek medical guidance before using any sauna.

What’s the most sensible choice for a first home sauna in the UK?

If you want minimal installation work, lower running costs, and a sauna you can use often, infrared is often the simplest starting point. If you know you want the classic Finnish-style experience and can support the electrics and ventilation, traditional can be a brilliant long-term centrepiece.
