Choosing between an infrared sauna and a traditional sauna is one of the most common questions that comes up during a purchase consultation, and the answer is rarely obvious without understanding what each type actually does to your body and your daily routine.

This article covers six products across both categories, three infrared and three traditional, helping you identify which suits your home, your schedule, and the kind of bathing experience you want from day one.

Key takeaways

• Traditional saunas heat the surrounding air to reach high ambient temperatures, while infrared saunas use radiant panels to warm the body directly at lower air temperatures.
• Infrared saunas warm up considerably faster than traditional heaters require and operate in a drier environment, making them a practical choice for shorter weekday sessions.
• Traditional saunas allow you to control both temperature and humidity by pouring water over heated stones, which is central to the Finnish löyly ritual.
• Infrared heat penetrates up to 1.5 inches into the skin via direct light wave action, whereas traditional heat warms from the outside in through the ambient air.
• The six products in this article span both categories, and the right choice often becomes clear once you understand the difference in heat delivery.

Infrared Sauna vs Traditional Sauna at a Glance

The Verdict

A traditional sauna uses a stone heater, either wood-burning or electric, to produce intense humid heat. According to Finnleo's comparison of sauna types, the temperature for a traditional sauna typically runs between 150 and 185°F. That is the kind of deep, enveloping heat that has defined Finnish sauna culture for centuries, and it produces the löyly steam experience when water is poured over the stones.

An infrared sauna uses carbon-fibre or ceramic panels to generate radiant heat that warms your body directly at lower air temperatures. According to Finnleo, the temperature for a far-infrared sauna is usually set between 120 and 140°F. The result is a gentler environment that is often easier to tolerate for longer sessions and reaches bathing temperature considerably faster than a traditional heater requires.

The six products featured below span both categories to match different priorities and garden setups. On the infrared side, the Insignia 2 Person Outdoor Infrared Sauna, the Kuro 2 Person Full Spectrum Infrared Sauna with Red Light Therapy, and the Insignia Hybrid Infrared and Traditional 2 Person Outdoor Sauna are built around lower-temperature, radiant-heat technology. On the traditional side, the Camilla 3 - 4 Person Traditional Outdoor Sauna Complete Kit, the Leil® Black Cube Classic 4 Person Outdoor Sauna Kit, and the Camilla Mini Traditional Outdoor Sauna 2 Person are all stone-heater units designed to deliver authentic high-heat steam sessions.

If your priority is the authentic Finnish steam ritual, the social sauna experience, or pairing your sauna with contrast cold therapy, the traditional options in this range are worth your closest attention. If you prefer faster warm-up times, a gentler heat environment, or an indoor-friendly footprint, the infrared options will be a closer fit. We sell the products below; here is how we chose them.

Products to consider

Infrared Sauna

Infrared saunas rely on light waves to create heat, with those waves penetrating the skin directly without warming the air around you. Rather than heating the ambient space to the high temperatures a traditional stove produces, infrared panels run at a meaningfully lower air temperature, which means the room is ready to use considerably faster and the session itself feels less intense on entry.

That lower ambient temperature makes the infrared sauna a practical option for weekday sessions where time is limited, and it suits anyone who finds the dense heat of a traditional Finnish sauna difficult to sustain for long periods. This section covers three products suited to the infrared experience.

Insignia 2 Person Outdoor Infrared Sauna

The Insignia 2 Person Outdoor Infrared Sauna is a two-person unit designed specifically for outdoor use, built from hemlock, a timber valued in sauna construction for its stability across fluctuating temperatures and its clean, light appearance that holds up through British winters with appropriate maintenance. Its compact footprint makes it a straightforward addition to most garden settings without requiring major ground preparation.

Best for couples or individuals who want a permanent infrared sauna in their garden without committing to a larger structure. The two-person capacity means households expecting regular group use will need to consider a larger option.

Kuro 2 Person Full Spectrum Infrared Sauna with Red Light Therapy

The Kuro combines full spectrum infrared technology with integrated red light therapy, giving you two wellness modalities within a single cedar structure. Cedar brings natural aromatic qualities and strong resistance to moisture, which contributes to its longevity whether the unit is positioned outdoors or indoors. The two-person capacity keeps the format personal and the footprint manageable.

Best for health-focused users who want to layer red light therapy into their recovery routine alongside infrared heat, rather than running two separate pieces of equipment. As with all two-person units, it works best as a personal or couples setup.

Insignia Hybrid Infrared and Traditional 2 Person Outdoor Sauna

The Insignia Hybrid offers both heating modes within a single hemlock structure. You can run it as an infrared session when you want a gentler, faster warm-up, or switch to traditional heat when you are after the denser, high-humidity experience that many seasoned bathers prefer. Having both options available in one unit gives you room to develop your bathing preference over time.

Best for buyers who are genuinely undecided between the two sauna types and want the flexibility to explore both without purchasing separate units. Its two-person capacity means the hybrid capability is best appreciated as a feature for personal or couples use rather than entertaining a larger group.

Traditional Sauna

A traditional sauna delivers the full Finnish experience through a stone heater that generates genuine steam and reaches high ambient temperatures when you pour water over the rocks to create löyly. As Finnleo's comparison of sauna types notes, the traditional sauna is the only bath in the world where the user controls both temperature and humidity, with humidity adjusted by how much water is thrown on the stones. The three outdoor thermowood units in this section are designed for year-round garden use in the UK climate, covering two to four bathers depending on your household's needs.

Camilla 3 - 4 Person Traditional Outdoor Sauna Complete Kit

Rated 4.9 out of 5 from 34 reviews on Heracles Wellness.

The Camilla 3 - 4 Person kit is a proprietary Heracles Wellness design, manufactured in Estonia and built from heat-treated thermowood that handles British weather reliably. The 6 kW heater is well-matched to a cabin of this capacity, reaching sauna temperatures without excessive warm-up time. It suits most households comfortably, whether you are bathing solo after a training session or sharing an evening with family.

Best for households of two to four who want a well-specified traditional outdoor sauna with the reassurance of a product designed and supported by the retailer. The 6 kW heater output is sized for this cabin's volume, so it is not the right unit if your group regularly runs to five or six bathers.

Leil® Black Cube Classic 4 Person Outdoor Sauna Kit

Rated 5 out of 5 from 13 reviews on Heracles Wellness.

The Leil® Black Cube Classic brings a more assertive specification to the traditional sauna category, with a 9 kW heater housed in a four-person thermowood outdoor cabin. The higher power output means the room reaches temperature efficiently and sustains consistent heat across longer or repeated sessions, while the cube format gives the unit a contemporary visual profile that suits modern garden settings.

Best for those who prioritise sustained, powerful heat delivery and want a traditional sauna that performs confidently across longer sessions and cooler months. The 9 kW electrical draw will require a qualified electrician to assess your supply and ensure compliance with UK wiring regulations before installation.

Camilla Mini Traditional Outdoor Sauna 2 Person

Rated 5 out of 5 from 3 reviews on Heracles Wellness.

The Camilla Mini is the most compact option in this traditional sauna lineup, seating two people in a thermowood outdoor cabin that fits gardens where space is a genuine constraint. It shares the same Estonian thermowood construction as the larger Camilla kit, so durability and weather resistance are not reduced by the smaller footprint.

Best for couples or individuals who want a dedicated, properly built traditional sauna without committing to a larger structure. With two-person capacity, this unit does not scale if your household or bathing group grows beyond that.

Which to Choose

The core difference comes down to how each type generates heat. Infrared saunas rely on light waves that penetrate the skin directly without warming the surrounding air, operating at a meaningfully lower air temperature with a considerably faster warm-up than a traditional heater requires. Traditional saunas heat the air in the room, and your body warms from the outside in, reaching high ambient temperatures with the option to pour water over the stones for löyly.

If the full Finnish experience is what you are after, the Camilla 3 - 4 Person Traditional Outdoor Sauna Complete Kit or the Leil® Black Cube Classic 4 Person Outdoor Sauna Kit will deliver that authentic steam and high ambient heat. If you prefer a gentler, quicker session with dry radiant warmth, the Insignia 2 Person Outdoor Infrared Sauna or the Kuro 2 Person Full Spectrum Infrared Sauna with Red Light Therapy is the more practical fit for daily use.
