Sauna Types Guide: Benefits & How to Choose Best One

Choose a traditional sauna if you want high air temperatures and löyly (water on hot stones); infrared if you prefer gentler heat, faster warm-up, and simpler home installation; a hybrid if you want both heating methods in one cabin; a steam room for continuous high humidity; and a portable sauna or blanket when budget or space is the main constraint. Before buying, compare installed cost, voltage and circuit requirements, ventilation, floor space, maximum temperature, maintenance, and warranty coverage. This guide walks through each type, what the research does and doesn't show, safety considerations, and how to match a sauna to your space.

Editorial disclosure: Sun Home Saunas manufactures and sells the infrared and traditional saunas discussed in this guide. Comparisons draw on the cited research, published product specifications, and the stated selection criteria; product links may lead to Sun Home products. A sauna is a wellness and comfort product, not a medical device — nothing here is medical advice, and you should talk to your doctor before sauna use if you are pregnant, have a cardiovascular condition, or take medication that affects heat tolerance. How this guide was developed: health statements are sourced to peer-reviewed research and public-health agency guidance and are framed to reflect study limitations; product specifications are verified against current Sun Home product and warranty pages and re-checked when the guide is updated; the health and wellness content is expert-verified and fact-checked by the credentialed reviewers named on this page (see the contributor bylines for their qualifications), while electrical and installation figures are drawn from manufacturer specifications and independent cost guides rather than from an in-house licensed electrician; and commercial considerations did not alter the research summary. Confirm any circuit, permit, or installation detail with a licensed electrician for your specific home.

Key takeaways

• The five common formats are traditional (steam/dry, high heat), infrared (radiant heat at lower air temperatures), hybrid (both in one cabin), steam room (continuous high humidity), and portable (blankets and fold-up cabins).
• Infrared saunas run at lower air temperatures and warm up faster than traditional saunas, which makes them easier to install and run at home; traditional saunas reach higher air temperatures and allow löyly.
• Match the format to how you will use it, then compare installed cost, voltage, ventilation, floor space, maximum temperature, maintenance, and warranty.
• Most published long-term sauna research studies traditional Finnish saunas, is observational, and does not establish that saunas cause the outcomes measured or that findings transfer directly to infrared, steam, women, or all populations.
• Warranty terms vary by model family — read the coverage table before assuming a single warranty applies across a brand's range.

What are the different types of saunas for home use?

Traditional saunas

A traditional sauna is heated by a wood-burning stove or an electric heater topped with stones. Pouring water over the hot stones produces löyly — a short burst of steam and humidity that is the defining feature of the Finnish sauna experience. Used without water on the stones, the same cabin functions as a dry sauna. Traditional saunas heat the air, and the hot air heats the body.

Air temperatures commonly run about 150–195°F, with many experienced bathers preferring the upper end and some cabins rated higher.[11] A wood-burning or electric traditional sauna typically takes 30–45 minutes to reach operating temperature and requires proper ventilation. Electric traditional heaters usually draw 240V on a dedicated 30A or higher circuit, which almost always means a licensed electrician.

Infrared saunas

An infrared sauna uses carbon or ceramic panels to emit infrared energy that warms the body directly rather than heating the surrounding air. Because the body is heated directly, infrared cabins produce a vigorous sweat at lower air temperatures than traditional saunas. Residential infrared saunas commonly operate around 110–135°F because they heat the body rather than the air, although some high-output models advertise maximum settings up to roughly 150–170°F.[11] They typically warm up in 15–20 minutes.

Far-infrared models use the longest infrared wavelengths; full-spectrum models add near- and mid-infrared wavelengths for a broader range. Many residential 1- to 3-person infrared cabins use a dedicated 120V/15A or 20A circuit, while larger and higher-output models may require 30A or 240V service. The lower-amperage plug-in models are one of the main reasons infrared is often simpler to install at home than traditional or steam options. For a deeper comparison of full-spectrum versus far-infrared, see our companion guide, infrared vs. traditional sauna.

Hybrid saunas

A hybrid sauna combines infrared panels and a traditional stone heater in one cabin, so you can run an infrared session, a traditional löyly session, or both. Heat-up time and operating temperature depend on which system you run. Hybrids suit buyers who genuinely want both experiences and have the space and electrical service for a traditional heater; they cost more than a comparable infrared-only cabin and carry the ventilation and higher-amperage wiring requirements of a traditional sauna.

Steam rooms

A steam room (steam sauna) uses a generator to boil water and release steam at regular intervals, holding the enclosure at roughly 110–120°F but at close to 100% relative humidity, which makes it feel much hotter. Steam rooms are typically built from tile, glass, and waterproofed surfaces, and they require a dedicated water supply, a drain, a steam line, and mechanical ventilation. They are the most construction-intensive of the five formats.

Portable saunas

Portable saunas — fold-up infrared cabins and infrared sauna blankets — are the lowest-cost and most space-flexible option. Most use far-infrared heating elements, plug into a standard outlet, and pack away between sessions. They deliver less enveloping heat and less durable construction than a fixed cabin, but they are a practical entry point for renters and small spaces.

Sauna type comparison

What does the research actually show about sauna health effects?

Sauna bathing is widely reported to be relaxing and enjoyable, and a growing body of research examines its physiological effects. It is important to read that research carefully, because most of it studies traditional Finnish saunas, most of it is observational, and the strongest headline findings come from a single population.

Cardiovascular associations

The best-known body of work is a long-running Finnish cohort. In the Kuopio Ischemic Heart Disease study, researchers followed 2,315 middle-aged men (aged 42–60) from eastern Finland for a median of about 21 years and reported that more frequent traditional-sauna use was associated with lower rates of sudden cardiac death and other fatal cardiovascular outcomes — men who used a sauna 4–7 times per week had a markedly lower adjusted risk of sudden cardiac death than men who used one once per week.[1] Two cautions matter. First, this is an observational study, so it shows association, not causation — it cannot rule out that healthier or more leisured men were the ones using saunas most. Second, the participants were middle-aged Finnish men using traditional saunas; the study's own authors caution against assuming the results transfer directly to infrared cabins, steam rooms, women, or other populations, and they call for further research.[2] Treat this as encouraging context, not proof that any sauna will lower your cardiovascular risk.

Heart-rate response

During a sauna session, heart rate commonly rises to roughly 100–150 beats per minute depending on temperature and duration, a range comparable to low- to moderate-intensity exercise.[2] This is a physiological stimulus, not evidence of a specific clinical benefit.

Relaxation and recovery

Many people find heat bathing relaxing, and it is commonly used for post-exercise muscle relaxation. These are among the most consistently reported and least controversial reasons people buy a home sauna. The evidence here is largely experiential and short-term rather than long-outcome.

Sweating and "detox"

A sauna makes you sweat, and a small study of 20 participants found that bisphenol A (BPA) could be detected in sweat, in some cases even when it was not detected in blood or urine.[3] That is not the same as evidence that sauna use meaningfully "detoxifies" the body, improves clinical outcomes, or that infrared removes more toxins than traditional heat. The liver and kidneys handle the body's detoxification; sweating is a minor excretion pathway. Claims that infrared sweat contains a substantially higher proportion of non-water compounds are not well established. Treat "detox" as a marketing shorthand for sweating, not a demonstrated medical effect.

Skin

Heat and sweating increase blood flow to the skin and can leave skin feeling refreshed, but robust evidence that sauna use raises collagen production or reverses skin aging is limited. We'd frame skin effects as a pleasant secondary experience, not a primary reason to buy.

The honest summary for a 2026 buyer: many people find sauna sessions genuinely relaxing and enjoyable; the traditional-sauna observational evidence on longevity is interesting but not proof of cause; and the strongest move is to treat a sauna as a wellness and comfort purchase rather than a medical intervention. Read the primary sources in the references below and decide for yourself.

Sauna safety and contraindications

Heat bathing is safe for most healthy adults, but it puts real stress on the cardiovascular system, and public-health agencies note that heat exposure raises the risk of dehydration and cardiovascular strain.[7] Consider the following before and during use, and talk to a physician if any apply to you.

• Hydration. You lose fluid through sweat. Drink water before and after, and don't sauna dehydrated.
• Alcohol. Do not combine sauna use with alcohol — it raises the risk of dehydration, low blood pressure, arrhythmia, and fainting, and heat-safety guidance specifically advises avoiding alcohol in the heat.[7]
• Pregnancy. Major obstetric guidance advises pregnant women to avoid saunas — particularly in the first trimester — because raising core body temperature can be harmful to fetal development. Consult your doctor before any sauna use during pregnancy.[9]
• Cardiovascular conditions. If you have heart disease, a history of heart attack, unstable angina, or a recent cardiac event, get medical clearance first — clinical reviews identify unstable angina, recent myocardial infarction, and severe aortic stenosis as contraindications to sauna bathing.[2]
• Blood pressure and medication. Heat lowers blood pressure and can interact with medications that affect heat tolerance, blood pressure, or hydration — the CDC notes that diuretics, some psychotropic medications, and certain drug combinations can increase heat-related risk. Ask your prescriber.[8]
• Session length for beginners. Start with short sessions (about 10–15 minutes) at moderate temperature and build up gradually as you learn your tolerance — general guidance suggests limiting a single sauna session to roughly 15 minutes and leaving sooner if you feel too hot.[10]
• Warning signs. Leave the sauna immediately if you feel dizzy, lightheaded, nauseated, short of breath, or notice a racing or irregular heartbeat — dizziness, heavy sweating, weakness, and nausea are recognized early warning signs of heat illness. Cool down and rehydrate.[7]
• Children and supervision. Children regulate heat differently from adults. Consult a pediatrician before allowing sauna use, and follow conservative temperature, duration, and supervision practices — brief sessions at lower temperatures, under direct adult supervision, if at all.
• When in doubt, ask. If you have any chronic condition or take regular medication, a brief conversation with your doctor before starting is the right call.

How to choose the best sauna for your space

Size and space

Sauna cabins are commonly built around seven feet of interior height to limit heat loss, though compact cabins around four-by-four feet work for solo use. A two-person cabin needs roughly the footprint of a small closet; multi-person cabins in the eight-by-twelve-foot range suit families. Plan for clearance around and above the cabin per the manufacturer's manual, and measure doorways and the delivery path before ordering.

Materials

Wood is the classic sauna material, and several species are used by reputable makers. Cedar (including Western Red Cedar and Canadian Red Cedar) resists rot, seldom splinters, and gives off a pleasant aroma when heated[4] — Sun Home's Luminar outdoor cabins use Canadian Red Cedar interiors. Cedar isn't the only quality option: kiln-dried hardwoods and properly cured softwoods such as eucalyptus and Canadian hemlock are all used in quality builds. Sun Home's Equinox saunas ship in eco-certified kiln-dried eucalyptus, and the Pod uses Canadian hemlock. Spruce and pine are traditional in Finnish saunas. What matters is that the wood is kiln-dried, dimensionally stable, and rated for repeated heating cycles. For the full trade-off matrix, see what kind of wood is best for a sauna.

Seating

Commercial saunas use tiered benches, with a lower bench acting as a footrest for people seated on the upper bench. Allow roughly two feet of bench width per person, and about six feet of length if users want to recline. Deeper benches are more comfortable; a lounging bench is worth it if you plan to lie down.

Location: indoor vs. outdoor

Indoor saunas are usually cheaper and simpler to install because the surrounding structure and climate control already exist. Outdoor saunas cost more and need a level, weather-appropriate site, but give you freedom on size and design and free up indoor space. For outdoor placement, consider a weatherproof cabin and plan the electrical run and site prep in advance. See important things to consider when getting an outdoor sauna.

Heat source and electrical requirements

Your choice of heat source drives both the experience and the installation cost. Infrared cabins run on carbon or ceramic panels; traditional saunas use electric or wood-fired stone heaters. On the electrical side, most Sun Home infrared saunas plug into a dedicated 120V/20A circuit (NEMA 5-20P), while larger and outdoor models require a dedicated 240V circuit — the Luminar 2-Person uses a 240V/20A circuit (NEMA L6-20P) and the Luminar 5-Person a 240V/30A circuit (NEMA L6-30P). Traditional electric heaters almost always need 240V on a 30A or larger circuit. Any 240V work, and any new dedicated circuit, should be planned with a licensed electrician, and installing new wiring can trigger a local electrical permit even for a plug-in model.

Cost, energy, and maintenance at a glance

Purchase price is only part of ownership cost. Budget also for electrical work, any ventilation or plumbing, energy, and maintenance. The per-session energy, installation, and maintenance figures below are editorial planning estimates based on heater wattage, assumed warm-up time, session duration, and thermostat cycling — not measured results for every model; actual consumption varies by model, ambient temperature, and user settings. The electricity rate is the U.S. average residential rate of about $0.19/kWh (EIA, April 2026)[5], and the full model-by-model breakdown is in our home sauna cost comparison. As rough planning figures:

• Energy per session (including warm-up): small infrared roughly 1.6–2.4 kWh; large full-spectrum infrared 3.5–5 kWh; traditional electric 6–10 kWh; steam generator 8–12 kWh. At three sessions per week, that is roughly $45–$150/year for infrared, $180–$300 for traditional electric, and $235–$360 for steam.
• Installation: a plug-in 120V/20A infrared cabin can be $0 beyond DIY assembly if a suitable outlet exists; 240V models and traditional electric saunas typically add $500–$1,500 for an electrician; steam rooms are multi-trade builds that commonly run several thousand dollars in labor plus plumbing and tile.
• Maintenance: infrared is lowest (wipe-down, minimal consumables); traditional adds occasional stone and heater-element care; steam is highest, with regular generator descaling and grout sealing.

Quick facts

• Energy use. Compact infrared and portable models typically draw about 1.5–3 kW; larger full-spectrum and traditional electric saunas draw more — a 2-person outdoor full-spectrum cabin can run around 4.8 kW, and traditional electric heaters commonly range from 6 kW upward depending on cabin size.
• Heart-rate stimulus. A 20-minute session can raise heart rate to roughly 100–150 bpm, comparable to low- to moderate-intensity exercise.[2]
• Warm-up. Infrared reaches operating temperature in about 15–20 minutes; traditional saunas usually take 30–45 minutes.

FAQs

What are the key differences between sauna types?

Traditional saunas heat the air to high temperatures (about 150–195°F) with a stone heater and allow löyly when you pour water on the stones. Infrared saunas use radiant panels to warm the body directly at lower air temperatures (about 110–135°F) and warm up faster. Hybrids combine both in one cabin. Steam rooms hold a lower air temperature at near-100% humidity. Portable saunas and blankets use infrared elements for a flexible, low-cost option.

How do I choose the best infrared sauna for home use?

Match the cabin to your space, your electrical service (120V/20A plug-in versus 240V requiring an electrician), your indoor-versus-outdoor placement, and your material preference. Cedar, eucalyptus, and Canadian hemlock are all quality wood options. Decide between far-infrared and full-spectrum based on whether you want the broader wavelength range, and confirm the published maximum temperature and warranty before buying.

Do infrared saunas warm up at lower temperatures than traditional saunas?

Yes. Infrared cabins operate at lower air temperatures (commonly about 110–135°F) because they heat the body directly rather than heating the room, and they typically reach operating temperature in 15–20 minutes versus 30–45 minutes for a traditional sauna. Many people find the lower air temperature more comfortable for longer sessions.

What features matter most in home sauna installation?

Interior height and footprint, bench depth and tiering, the heat source, and the electrical requirement (a dedicated 20A or 30A circuit, 120V or 240V) all affect comfort, cost, and feasibility. Indoor-versus-outdoor placement determines site prep and whether you need weatherproof construction. Plan any new circuit or 240V work with a licensed electrician.

Is a sauna good for my health?

Many people find sauna sessions relaxing and use them for post-exercise recovery, and observational research on traditional Finnish saunas has linked frequent use to better cardiovascular outcomes — but that research is associational, studies a specific population, and does not prove a sauna will improve your health. Treat a sauna as a wellness and comfort purchase, and consult your doctor before starting if you are pregnant, have a cardiovascular condition, or take medication affecting heat tolerance.
