Infrared VS Traditional Saunas : Which Is Right For You?

 

Bringing the warmth and wellness of the sauna home is one of the best investments you can make for your physical and mental well-being — but with two distinct styles to choose from, it can be hard to know where to start. Traditional saunas have been enjoyed for centuries, while infrared models have grown rapidly in popularity thanks to their unique heating method and lower operating temperatures.

 

At TheHeatCabin, we believe there’s no single "best" option — only the best option for you. This guide breaks down exactly how each works, their benefits, costs, and practical differences, so you can choose with confidence.

 

 

 

How Each Works — Heat Source & Temperature Range

 

 

Traditional saunas — also called Finnish saunas — heat the air inside the cabin to warm your body. Most use electric or wood-burning stove heaters, which warm the air to between 70°C and 100°C. The heat then radiates onto your skin, raising your core temperature and making you sweat. Many models include sauna stones on the heater; pouring water over them releases a burst of steam known as löyly, which adds humidity and intensity to the experience.

 

 

Infrared saunas work very differently — instead of heating the air, they use infrared heating panels that emit radiant heat directly onto your body. This heats you, not the air around you. The cabin air typically only reaches 45°C to 60°C — much cooler to the touch — yet your body reaches the same core temperature as in a traditional sauna. Infrared wavelengths penetrate deep into the skin and tissues, creating a gentle, deeply warming experience without the intense surface heat.

 

 

 

 

Both styles deliver a range of well-being benefits — here's how they compare:

 

 

-  Deep sweating & refreshed well-being — encourages profuse sweating, leaving many people feeling cleansed and revitalised

-  Improved circulation — blood vessels dilate, supporting healthy blood flow

-  Muscle relaxation & recovery — eases tension and may help soothe tired muscles after activity

-  Better sleep quality — the warming experience can promote deeper, more restful sleep

-  Stress reduction — helps create a moment of calm, lowering stress levels and boosting relaxation

-  Immune system support — regular use, alongside a balanced lifestyle, may help support overall well-being

 

A note on well-being and health: Sweating is the body's natural way of regulating temperature. While some research suggests trace elements may be excreted through sweat, the body's primary natural detoxification functions are carried out by the liver and kidneys. Sauna use should be enjoyed as part of a healthy lifestyle — not as a replacement for a balanced diet or medical advice. If you have any existing health conditions, always consult a healthcare professional before using a sauna. 

 

 

-  Deeper tissue warmth — infrared heat penetrates more deeply into the body, creating a gentle, warming sensation that many find soothing

-  Joint comfort & mobility — the deep, gentle heat can be particularly helpful for soothing stiff joints and comforting muscles

-  Easier breathing — lower operating temperatures make the experience more comfortable if you find intense heat difficult to tolerate

-  Metabolic boost — the body works to regulate temperature, which can increase metabolic rate during sessions

 

 

-  Classic intense heat experience — the authentic, high-heat sauna ritual enjoyed across the world for centuries

-  Powerful respiratory comfort — the dry heat, followed by bursts of steam, can feel clearing and comforting for the airways

-  Pure, simple design — natural materials and straightforward heating with minimal electronics

 

 

 

Heat-Up Time & Energy Use — Practical Daily Differences

 

Feature Traditional Sauna Infrared Sauna 

Heat-up time 30–60 minutes 10–15 minutes 

Ready when you are? Needs advance planning  Almost instant 

Typical power draw 4.5kW – 9kW 1.2kW – 2.6kW 

Insulation needs High — retains extreme heat Standard — works well with basic insulation 

 

Practical takeaway: Infrared saunas are perfect for spontaneous sessions — switch it on and you're good to go in 15 minutes. Traditional saunas reward planning; many owners heat theirs up while getting dinner ready, enjoying the ritual as part of the evening routine.

 

 

 

 Running Costs — What To Expect In The UK

 

With energy prices a key consideration for UK households, here's a realistic estimate based on typical usage and current average electricity rates (~24p per kWh):

 

Infrared Sauna

 

- Average power: 1.8kW

- 30-minute session: ~0.9 kWh → ≈22p per session

- Monthly (3 sessions/week): ≈£2.70

 

Traditional Electric Sauna

 

- Average power: 6kW

- 45-minute heat-up + 30-minute use: ~5.5 kWh → ≈£1.32 per session

- Monthly (3 sessions/week): ≈£16.00

 

 Note: Wood-burning traditional saunas have near-zero running costs but require ventilation, outdoor space, and fuel storage — great if you have the room!

Energy prices are subject to change: — check your current tariff for accurate figures.

 

Bottom line: Infrared is significantly cheaper to run — roughly 1/5th the cost of a standard electric traditional sauna.

 

 

 

 Who Should Buy Which? — Quick Decision Guide

 

Choose An Infrared Sauna If:

 

-  You want quick heat-up — use it whenever the mood strikes

-  You want lower running costs

-  You prefer gentler heat — don't like intense, stifling temperatures

-  You want joint pain or muscle recovery benefits

-  Space is limited — they're often more compact

-  It's going indoors — bedroom, bathroom, study, or spare room

 

Choose A Traditional Sauna If:

 

-  You love the authentic, classic sauna experience

-  You enjoy high heat (80°C+) and the ritual of steam

-  You have space to heat it in advance

-  You want it in a garden building, garage, or dedicated sauna room

-  You may want a wood-burning model for zero running costs and atmosphere

-  You prefer simple, durable design with minimal electronics

 

 

 

Final Thoughts

 

There's no wrong choice — just the right choice for your lifestyle. If you value convenience, low running costs, and gentle deep-heat therapy, infrared is the clear winner. If you crave the classic ritual, intense heat, and that authentic sauna atmosphere, go for traditional.

 

Many enthusiasts even start with infrared for daily use and dream of adding a traditional outdoor sauna later — the best of both worlds!
