Types of Saunas Explained: Infrared, Traditional, Barrel & More
Discover the key differences between every sauna style so you can choose the perfect heat experience for your health and lifestyle.
The main types of saunas are traditional Finnish, infrared, full-spectrum infrared, barrel, and hybrid designs, each differing in how heat is generated, the temperature range it produces, and where that heat acts on the body, factors that matter far more to daily experience than any single specification.
- The most meaningful difference between sauna types is not peak temperature but whether the heat warms the air around you or radiates directly into your body's tissues.
- 160 to 195 versus 120 to 150: Traditional saunas run between 160 and 195 degrees Fahrenheit while infrared saunas stay in the 120 to 150 range, which many people find easier on the cardiovascular system.
- The curved interior of a barrel sauna reduces the volume of air to heat and improves natural circulation, so it reaches temperature faster than a box-shaped room of the same bench capacity.
- Infrared units are built for indoor use on standard household circuits, while outdoor traditional saunas require a level base, weather-ready construction, and often a permit for permanent installation.
- People who find high heat uncomfortable tend to land on infrared, while those who want steam lean traditional, but the best sauna is whichever one fits your space and routine well enough to use regularly.

What Actually Separates the Different Types of Saunas
Most people think the main difference between sauna types is how hot they get. In practice, the more important differences are how the heat is generated, where it acts on the body, and what kind of environment you end up sitting in. Once you understand those three things, choosing between an infrared cabin, a traditional Finnish-style room, a barrel, or a hybrid becomes a lot more straightforward.

The broadest split is between radiant heat and convective heat. Traditional saunas heat the air around you, which in turn heats your body. Infrared saunas direct radiant energy at your skin and tissues more or less directly, keeping the ambient air temperature lower. Both approaches produce a sweat response, but the feel of each session is noticeably different, and that subjective experience matters as much as any specification when you are choosing something you will use every week for years.
Shape and placement also come into it. Barrel saunas are a form factor, not a heat type. A cube or cabin-style sauna describes the structure. These categories can overlap: a barrel can run a traditional wood-fired heater or an infrared panel. Keeping the "how it heats" question separate from the "what it looks like" question will save a lot of confusion as you read further.
Traditional Finnish Saunas: High Heat, Steam, and Rocks
The traditional Finnish sauna is what most people picture first: a wood-lined room, a heater stacked with volcanic rocks, temperatures that typically run between 160°F and 195°F, and the option to ladle water over the rocks to produce a burst of steam called löyly. The humidity in a well-run Finnish sauna cycles between dry and intensely steamy, which is part of what makes the experience distinctive.

The heater is the centerpiece. Electric heaters with integrated controls are the most practical choice for home use, and the output is measured in kilowatts relative to the room volume. The Harvia 6 kW stove found in some of the hybrid models here gives a sense of the scale appropriate for a three-person room; a larger six-person space calls for something closer to 8 kW. Wood-fired heaters are an option too, particularly for outdoor installations, and they add a genuine ritual quality to the session, though they require more management and appropriate ventilation.
The Leil Viva series is a good example of how a traditional outdoor sauna is built for longevity. All three models in the range use 40mm ThermoWood construction, a heat-modified timber that resists moisture and dimensional change better than untreated wood. The thermo-alder benches inside are similarly chosen for low heat transfer, so they stay comfortable to sit on even at high temperatures. Features like the three-point ventilation system and the EPDM-sealed roof on the Viva 180 and Viva 210 are there to make sure the structure performs year-round, not just on mild days.
If you are browsing saunas for the first time and you enjoy steam baths or hot yoga, a traditional sauna will probably feel most natural to you. The sensory experience, the smell of hot wood, the sound of water hitting stones, is genuinely different from anything an infrared panel produces.
Infrared Saunas: Lower Temperature, Deeper Sweat
Infrared saunas work at substantially lower air temperatures, typically between 120°F and 150°F, but the radiant panels deliver energy directly into the body's tissues rather than heating the surrounding air first. The result is a sweat response that many people find less taxing on the cardiovascular system than a traditional sauna at peak heat. Research on infrared therapy generally finds benefits consistent with heat exposure broadly, including improved circulation and muscle recovery, though the specific mechanisms differ from convective heat.

The panels themselves matter quite a bit. Carbon panel heaters produce long-wave far-infrared and distribute heat evenly across a larger surface area. Short-wave or near-infrared heaters penetrate tissue more deeply, though they operate at higher intensity. Full-spectrum designs combine near, mid, and far infrared wavelengths in a single unit. The Dynamic Saunas Monaco, for example, uses 15 PureTech Ultra Low EMF far-infrared carbon panels across a six-person interior, producing an EMF reading of 3 to 5 milligauss measured two to three inches from the panels. EMF levels are a legitimate concern for frequent users, and models marketed as "ultra low EMF" are worth comparing on actual published figures rather than marketing claims alone.
Infrared saunas are almost exclusively designed for indoor use. The Dynamic Saunas Monaco is built from natural reforested Canadian Hemlock and requires two separate dedicated 20-amp, 120-volt circuits rather than a single high-voltage supply. That electrical setup is easier for most homes than the 240V service a larger traditional heater needs, though it still requires a licensed electrician to install the dedicated circuits correctly. The Monaco also includes chromotherapy lighting, a red light feature, and a Bluetooth sound system, which puts it in a category aimed at full-session wellness rather than raw heat therapy alone.
Full-Spectrum Infrared: What the Term Actually Means
Full-spectrum infrared is a specific claim that some buyers encounter and find confusing. A standard far-infrared sauna produces wavelengths in the 5.6 to 15 micron range. A full-spectrum unit adds near-infrared (shorter wavelengths, higher intensity, deeper tissue penetration) and mid-infrared in between. The idea is to cover the complete range of therapeutic wavelengths in a single session rather than committing to one band.
Whether the practical difference justifies a price premium depends on your goals. Near-infrared exposure has been studied separately for skin health and cellular recovery. Far-infrared is associated more broadly with the heat response and circulation effects people seek from sauna use. Some of the hybrid models available here combine full-spectrum infrared panels with a traditional steam heater, which means you can dial in the experience session by session rather than being locked into one approach.
The Finnmark FD-4 Trinity is an example that makes this concrete: it pairs UL-listed full-spectrum infrared heaters with a 1.9 kW traditional sauna heater and medical-grade red light therapy panels, all running from a standard 120V outlet. That combination in a single cabinet is genuinely unusual. Most full-spectrum units you will find are infrared only, and the distinction matters if steam is part of what you want.
Hybrid Saunas: Traditional and Infrared in One Cabinet
A hybrid sauna runs both an infrared heating system and a traditional rock-and-stove heater in the same enclosure. The appeal is flexibility: use the infrared panels for a quick 30-minute session on a weekday, then fire up the traditional heater for a longer, steamier weekend ritual. You are not choosing between experiences, you are keeping both available.
The tradeoff is that doing two things well in one box is harder than doing one thing well. Hybrid units need to handle the high ambient temperatures a traditional heater produces without damaging the infrared panels, and the electrical requirements are more complex because the two systems often need separate circuits. The Finnmark FD-6, a four-person outdoor barrel hybrid, handles this by requiring 120V for the infrared side while the optional traditional heater needs a 240V supply. That separation keeps the infrared system accessible to more homes even if the steam heater requires an upgrade.
Hybrid models also tend to sit higher in the price range than a comparably sized single-mode sauna. If you are certain you will only use infrared, the hybrid premium buys you capability you will not use. If you are genuinely undecided, or if you expect multiple people with different preferences to use the sauna, the hybrid case is stronger. Understanding how barrel and traditional configurations compare in day-to-day use can help you decide whether a hybrid is worth the added complexity for your situation.
Barrel Saunas: Shape as a Functional Choice
A barrel sauna is defined by its cylindrical cross-section, which is not just an aesthetic preference. The curved interior geometry means hot air naturally circulates from the top of the arc down the sides toward the benches, reducing the temperature gradient between head and foot level that flat-ceilinged rooms can struggle with. Less volume to heat also means a shorter warm-up time compared to a box-shaped room of the same bench capacity.
Barrel saunas are almost always outdoor structures, built from stave-glued cedar or similar softwoods. The stave construction that gives the shape its strength also handles expansion and contraction from temperature swings reasonably well, which matters for year-round outdoor use. Most of the barrel models in this category are designed for traditional or wood-fired heaters, though hybrid barrel configurations exist.
For anyone comparing footprints, a barrel sauna typically takes up less ground space than a cabin-style room of the same seating capacity, which can be relevant for smaller yards. The tradeoff is that the interior headroom varies depending on where you are sitting, and the curved walls limit how much shelving or accessory space you can add. If footprint is a concern, reading through how barrel capacity translates to actual interior dimensions is a useful exercise before committing.
Cabin-Style and Cube Saunas: Outdoor Traditional with a Modern Face
Cabin-style and cube saunas are box-shaped outdoor structures, usually prefabricated as kits. The distinction between "cabin" and "cube" is mostly visual: a cabin sauna tends to have a pitched roof and a look closer to a garden shed, while a cube sauna has a flat or minimally sloped roof and a more architectural, angular profile. Both run traditional heaters as standard, and both are designed for permanent outdoor installation.
The Leil Viva series sits squarely in this category. The Viva 180 at $11,990, the Viva 210 at $13,190, and the Viva 250 at $15,390 represent three sizes of the same fundamental design: 40mm ThermoWood walls, thermo-alder benches, bronze-tempered glass doors, and a three-point ventilation system. All three are DIY-friendly enough to assemble in a single day. The size differences affect interior layout as much as raw floor area: the Viva 180 uses a face-to-face bench arrangement suited to social sessions, while the Viva 210 opens up a reclining layout, and the Viva 250 adds the most interior movement space of the three.
The appeal of the cabin or cube format over a barrel is largely about how you want the sauna to feel. Flat walls, full standing height throughout, and the ability to add accessories more easily make cabin saunas closer to a dedicated wellness room than a minimalist outdoor heat box. If you are comparing these formats in detail, the differences between barrel and cube structures go deeper than aesthetics and are worth reading through before you decide on a shape.
Portable and Tent Saunas: Low Commitment, Real Heat
Sauna tents sit at the other end of the permanence spectrum. A wood-burning tent sauna like the North Shore Sauna Mini Cube can reportedly reach 180°F to 200°F in around 15 minutes, which is faster than most fixed structures. Setup for some tent designs takes under 10 minutes using a pop-up hub frame. The tradeoff is obvious: a tent is not a permanent installation, the experience is less refined, and you are managing an open flame in a fabric enclosure, which demands careful attention to placement and ventilation.
For someone testing sauna habits before committing to a permanent build, or for someone who wants an outdoor option that packs away seasonally, a tent sauna is a legitimate starting point rather than a compromise. The heat is real; what you are giving up is the longevity, the aesthetics, and the immersive quality of a properly insulated wood structure.
Indoor Versus Outdoor: How Placement Shapes Your Choice
Placement is a practical filter that narrows your options faster than almost anything else. Infrared saunas are built for indoor use, typically running on standard household circuits (with dedicated breakers), and they fit into a basement, a spare room, or a large bathroom. Traditional and hybrid outdoor saunas need a level base, weather-appropriate construction, and in most jurisdictions a permit if they are permanent structures. That paperwork is worth factoring into your timeline.
Outdoor traditional saunas, including the Leil Viva models, are engineered specifically to handle temperature swings, moisture, and UV exposure over years of use. The ThermoWood shell and EPDM-sealed roofing on these units are not incidental choices; they are what separates a sauna that looks the same after five winters from one that warps and degrades. An indoor infrared cabinet does not face those stresses but needs good room ventilation to manage the heat load and moisture it produces during sessions.
People who use their sauna most frequently tend to be those who made it as easy as possible to access. An infrared unit inside the house has a lower barrier to use than an outdoor structure you have to get dressed and walk to in January. That behavioral reality is worth weighing alongside the technical differences between heat types. For a deeper look at how traditional indoor configurations compare to outdoor ones, the comparison of indoor traditional sauna options covers the variables specific to that placement.
Side-by-Side: Infrared Sauna Models at a Glance
The table below covers a range of infrared and far-infrared models to illustrate how capacity, price, and EMF classification vary across the lineup. These are all indoor units running on standard 120V circuits unless otherwise noted.
| Model | Capacity | EMF Rating | Price |
|---|---|---|---|
Dynamic Saunas 1 Person Compact (DYN-1101-01 Elite) |
1 person | Low EMF | $1,099 |
Dynamic Saunas 1 Person Compact (DYN-1201-01 Elite) |
1 person | Low EMF | $1,299 |
Dynamic Saunas Avila 1-2 Person (DYN-6103-01) |
1-2 person | Low EMF | $1,899 |
Dynamic Saunas Avila 1-2 Person (DYN-6103-01 Elite) |
1-2 person | Ultra Low EMF | $2,099 |
Dynamic Saunas Barcelona 1-2 Person (DYN-6106-01) |
1-2 person | Low EMF | $1,899 |
Dynamic Saunas Bellagio 3 Person (DYN-6306-02) |
3 person | Low EMF | $2,699 |
The jump from Low EMF to Ultra Low EMF within the same model line, as seen with the Avila 1-2 Person, typically reflects a panel upgrade rather than a different heater type. Whether that distinction matters to you depends on how frequently you plan to use the sauna and how closely you sit to the panels during a session. For anyone considering a two-person infrared unit specifically, the practical differences between a solo and a shared-size cabin are worth thinking through before settling on a capacity.
Choosing the Right Type for Your Situation
The honest answer is that most people enjoy whichever sauna they actually use consistently, and the best type is the one that fits your space, your routine, and your heat tolerance. That said, a few patterns hold up well across buyers. People who find very high heat uncomfortable, or who want a quicker, lower-barrier session, tend to prefer infrared. People who grew up with traditional saunas, or who specifically want the steam ritual, find infrared feels like a different activity rather than a better version of the same one.
Outdoor space and willingness to do a proper installation usually tilt buyers toward traditional or barrel formats. If you have a yard, a level surface, and a taste for a project, an outdoor cabin sauna becomes a permanent feature of your property rather than a piece of furniture in a room. The Leil Viva 180's face-to-face layout and compact footprint are designed for exactly that scenario: a social, year-round outdoor sauna that fits into a normal backyard without dominating it. Pairing regular sauna use with cold plunges is something many buyers consider at this stage, since the contrast protocol is most practical when both are accessible from the same outdoor area.
Budget matters too, though not always in the direction people expect. Entry-level infrared cabins start well under $2,000. A well-built outdoor traditional sauna like the Viva 180 starts at $11,990 before you factor in a heater. Hybrid models and full-spectrum infrared units sit in the middle. The right question is not which type is cheapest but which type you will use enough to justify the investment. A sauna that matches how you actually want to spend 30 minutes three times a week is worth more than a technically superior one that you find too hot, too inconvenient, or too finicky to use regularly.

Frequently asked questions
Which type of sauna is best suited to first-time buyers who already enjoy steam rooms or hot yoga?▾
A traditional Finnish-style sauna is the most natural starting point for people familiar with steam and high heat. The session feel, hot wood smell, humidity from ladling water over the rocks, and temperatures between 160F and 195F all translate well from those environments. Infrared saunas are a valid alternative, but the experience is genuinely different enough that it surprises some buyers who expected something similar.
Are infrared saunas safe for regular home use, and what should I know about EMF exposure?▾
Far-infrared carbon panel saunas are widely used at home and are generally considered safe for healthy adults. EMF output is a reasonable thing to check, and the Dynamic Saunas Monaco publishes a specific figure of 3 to 5 milligauss measured two to three inches from the panels, which gives you something concrete to compare against other models rather than relying on vague marketing language. If you use a sauna several times a week, choosing a unit with published EMF figures rather than one that simply uses the words ultra low EMF is the smarter approach.
What does a traditional outdoor sauna like the Leil Viva series cost, and what drives the price difference between models?▾
The Leil Viva 180 is priced at $11,990, the Viva 210 at $13,190, and the Viva 250 at $15,390. The price increases with interior size and layout, moving from a compact face-to-face design in the 180 up to the most spacious configuration in the 250. All three use the same 40mm ThermoWood construction and thermo-alder benches, so the core materials and build quality are consistent across the range.
How difficult is it to set up an outdoor traditional sauna at home?▾
The Leil Viva models are designed for DIY assembly and are marketed as installable in a single day. That is realistic for two people with basic tools, since the components arrive pre-cut and the interlocking ThermoWood panels are engineered to fit together without complex carpentry. The heater is sold separately, and if you go with an electric model you will still need an electrician for the dedicated circuit, which is worth scheduling before the sauna arrives.
What are the ongoing running costs of an infrared sauna compared to a traditional one?▾
Infrared saunas generally cost less to run per session because they operate at lower air temperatures and heat up faster. The Dynamic Saunas Monaco runs on two separate dedicated 20-amp, 120-volt circuits rather than a high-voltage 240V supply, which is a lighter electrical load than a larger traditional heater. Traditional saunas with heaters in the 6 to 8 kW range draw more power and take longer to reach operating temperature, so the gap in running cost adds up over frequent use.
What maintenance does a traditional outdoor sauna actually need?▾
ThermoWood construction, which is used across the Leil Viva range, resists moisture absorption and dimensional warping better than untreated timber, so exterior maintenance is minimal compared to a standard pine or cedar structure. The EPDM-sealed roof on the Viva 180 and Viva 210 handles weather without needing re-sealing. Inside, the main tasks are wiping down the thermo-alder benches after sessions and keeping the heater rocks in good condition, replacing them every couple of years as they degrade from repeated thermal cycling.
How do I know what size sauna to buy for my household?▾
Capacity ratings are a guide, not a guarantee of comfort. A four-person rating like those on the Leil Viva 180, 210, and 250 describes a usable bench layout, but the actual feel of the space varies because the 250 offers a more expansive interior with greater movement room than the more compact 180. For a couple using the sauna regularly with occasional guests, the 180 is practical. Households that want room to recline or regularly have four adults at once will find the 210 or 250 worth the step up.
What is the most common mistake buyers make when choosing between infrared and traditional saunas?▾
Most people focus almost entirely on temperature and assume a hotter sauna is a more effective one. The more useful question is what kind of session you actually want. Traditional saunas at 160F to 195F with steam produce a very different physiological and sensory experience than an infrared session at 120F to 150F, and neither is universally superior. Buying an infrared sauna because it is cheaper or easier to install, then discovering you miss the steam and high-heat intensity, is a frustrating and expensive mistake to make.
