Deciding
What's the difference between an infrared and a traditional sauna?
A traditional sauna heats the air (and stones) to 160-200°F and you can pour water for steam; an infrared sauna heats your body directly at 120-150°F air temperature. Infrared is cheaper to buy and run and plugs into a normal outlet in smaller sizes; traditional gives the hotter, steamier, classic experience. Full guide →
Is it better to buy a sauna online or in person?
Online for most people: better prices, every brand, and return windows of 30 days to a year. In person makes sense for custom traditional rooms, luxury outdoor builds, or if you've never felt traditional heat and want to before spending $8,000+. Full guide →
What's the best sauna?
For most buyers, a full-spectrum infrared cabin from Clearlight, Sunlighten or Sun Home; for the classic experience, a cedar barrel or cube from Almost Heaven, Redwood Outdoors or Sweat Kingdom. It depends on space, power and budget, which our rankings and best-of lists sort by. Full guide →
How much does a sauna cost?
Blankets $350-$700, tents $1,500-$2,500, infrared cabins $1,000-$14,000 (most good ones $4,000-$8,000), barrel and cube kits $4,000-$10,000 plus heater, custom rooms $10,000 and up. Add $300-$1,500 for an electrician on 240V models. Full guide →
What can I get for under $2,000?
A wood-fired tent (SweatTent, North Shore), a one- or two-person plug-in infrared cabin from JNH, a portable like Therasage, a steam tent, or any blanket. Not a traditional electric sauna; those start higher once you add the heater. Full guide →
Is full spectrum worth it over far infrared?
For the sauna effect itself, no; far infrared does the heating. Full spectrum adds near-infrared emitters whose dose varies a lot by brand. At $5,000+ it's standard anyway; under $4,000, buy a good far-infrared cabin and a red light panel if you want NIR. Full guide →
Indoor or outdoor?
Indoor for convenience and daily use, and for infrared. Outdoor for traditional heat, steam, wood-fired and the hot-cold ritual, at the cost of a pad, outdoor wiring and yearly finishing. Full guide →
Which wood should I pick?
Cedar or thermowood outdoors. Hemlock for a budget indoor infrared. Basswood if you're sensitive to scent or allergens. Aspen or alder for benches you sit on in a traditional sauna. Full guide →
Space and power
How much room do I need for a sauna?
A one-person infrared cabin is about 3 x 3 feet; a two-person about 4 x 3.5 feet; a four-person about 6 x 4 feet. Add 2 feet in front for the door and 4-6 inches behind for airflow, and a ceiling at least 2 inches taller than the cabin (most are 75-78 inches). A 6-foot barrel needs roughly 7 x 8 feet of level ground. Full guide →
How big is a sauna?
Home saunas run from a 36 x 36-inch one-person booth to 8 x 6-foot family rooms. The most popular size, a two-person infrared cabin, is about 48 wide x 42 deep x 77 inches tall and weighs 350-500 lb. Full guide →
How many people really fit in a '4-person' sauna?
Four sitting shoulder to shoulder; two or three comfortably; one lying down. Manufacturers count about 18-20 inches of bench per person. Buy one size bigger than the number of people who'll use it together. Full guide →
How much power does a sauna use?
A two-person infrared cabin draws about 1.6 kW and uses roughly 1.5 kWh per session (about 25 cents). A traditional sauna with a 6-9 kW heater uses 6-9 kWh per session (about $1-$1.50). Blankets use a fraction of that. Full guide →
Do I need an electrician?
Not for blankets, tents or most one- and two-person infrared cabins, which plug into a standard 120V outlet. Yes for larger infrared cabins and almost all electric traditional heaters, which need a dedicated 240V circuit ($300-$1,500 installed). Full guide →
Can I use an extension cord?
No. Saunas draw sustained high current and cheap cords overheat. Plug directly into the outlet, ideally on a circuit nothing else shares. Full guide →
Can I put a sauna in an apartment?
Yes: a blanket, a portable, or a one- or two-person 120V infrared cabin. Cabins weigh less per square foot than a loaded bookshelf, run dry, are nearly silent, and come apart for moving. Full guide →
Can I put a sauna in a basement or garage?
Yes, and both are common. Check ceiling height (basements are often under 7 feet), and in a garage make sure the outlet is on its own circuit and the cabin isn't near fuel or chemicals. Unheated garages make traditional saunas slower to warm up. Full guide →
Does a sauna need a drain or ventilation?
Infrared cabins: no drain, and only the built-in vent. Traditional saunas: a vent high and low for airflow, and a drain is recommended indoors if you'll throw water; outdoor barrels and cubes drain through the floor gaps. Full guide →
How much does a sauna cost to run per month?
An infrared cabin used four times a week: about $4-$8 a month. A traditional electric sauna at the same frequency: $15-$30. Wood-fired: the cost of firewood, roughly $1-$3 per session. Full guide →
Ordering and delivery
How long does a sauna take to ship?
Blankets and portables in 2-7 days. In-stock infrared cabins and barrel kits in 1-4 weeks by freight. Backordered models 4-12 weeks. Custom traditional rooms 6-16 weeks. Full guide →
Is shipping free?
Most brands include curbside freight shipping in the lower 48 states. Hawaii, Alaska, and anything beyond the curb (into the garage, upstairs, unpacking) costs extra, typically $150-$600. Full guide →
What does curbside delivery mean?
The freight driver lowers the pallet to the ground at your curb or driveway and leaves. Moving it inside and unpacking is on you. Have a helper; infrared cabins are 350-500 lb, barrel kits 1,000-2,000 lb. Full guide →
Do I have to build a sauna if I order one online?
Yes, to some degree. Blankets need nothing; tents take 10-30 minutes; infrared cabins clip together in 1-2 hours with two people and usually no tools; barrel kits take a day with a drill; cube kits take a weekend. You can pay for assembly, from about $150 for a cabin to $1,200 for a barrel. Full guide →
What if it arrives damaged?
Note any damage on the delivery receipt before signing and photograph it. Report it to the brand within their window (often 48 hours). Brands replace damaged panels routinely; a clean signature makes it harder. Full guide →
Can I return a sauna?
Usually, within 30 days (Relaxe gives 365). You typically pay return freight ($300-$800 for a cabin) and sometimes a restocking fee (SweatTent charges 30%). Custom and made-to-order saunas are usually final. Read the policy before you order. Full guide →
Does the price include the heater?
For infrared cabins, yes. For many barrel and cube kits, no: the heater is $700-$2,000 extra and the wiring on top. Check the 'what's included' list, not the headline price. Full guide →
Do I need a permit?
For the electrical work on any 240V sauna, yes, and your electrician pulls it. For an outdoor structure, it depends on your city and the footprint (often over 100-200 square feet). Indoor infrared cabins on 120V need nothing. Full guide →
Should I buy direct from the brand or from a retailer?
Direct is usually cheapest and cleanest for warranty claims. Multi-brand retailers can bundle accessories or shipping. Big-box sites sell the budget tier with easy returns; warranty still goes through the manufacturer. Full guide →
Safety and health
Is it safe to have a sauna if I have kids?
Yes, with supervision. Kids 6 and up can take short, cool sessions on the lowest bench with an adult present; under 2 shouldn't. Childproof with a heater guard, PIN-locked controls and a door that always opens from inside. Pets shouldn't use it. Full guide →
How hot should a sauna be?
Traditional: 150-195°F, most people settle at 170-180°F. Infrared: 120-150°F air temperature, which feels hotter than it sounds. Start lower and shorter for the first two weeks. Full guide →
How long should I stay in?
Beginners 5-10 minutes; established users 15-20 per round, with cool-downs between two or three rounds. The Finnish health studies used about 20 minutes at 175°F, several times a week. Full guide →
Is infrared sauna EMF dangerous?
Levels in well-made cabins are below those of a hair dryer and similar to household background at the seat. There's no established harm at these levels; treat 'low EMF' with third-party testing as a sign of build quality, not a safety emergency. Full guide →
Do saunas help you lose weight?
Directly, barely: 50-150 calories a session, and the scale drop is water. Indirectly, through better sleep, recovery and consistency, they can help. Don't buy one as a fat-loss device. Full guide →
Can I use a sauna every day?
Healthy adults can; the Finnish cohort data shows the strongest associations in people using it 4-7 times a week. Stay hydrated, listen to your body, and check with a doctor if you have heart disease or blood pressure issues. Full guide →
Who shouldn't use a sauna?
People who are pregnant, have unstable heart conditions, very low or uncontrolled high blood pressure, a recent heart attack or stroke, or take medications that impair sweating or heart rate should ask a doctor first. Nobody should sauna drunk. Full guide →
Is a sauna a fire risk?
Electric saunas from established brands are UL/ETL listed and the risk is low when installed per the manual with proper clearances. Wood-fired saunas carry the normal risks of a stove: keep clearances, sweep the chimney, never leave a fire unattended. Full guide →
Owning one
How do I clean a sauna?
Sit on a towel, wipe the bench after use, leave the door open to dry. Weekly, wash benches with warm water and mild soap. Sand sweat marks lightly a few times a year. Never use bleach, varnish or a pressure washer. Full guide →
How long does a sauna last?
A cedar or hemlock cabin, 20 years or more. Infrared emitters are rated for 20,000-50,000+ hours and rarely need replacing. Traditional heater elements last 5-10 years; stones 1-3 years. Tents last a few years of regular use. Full guide →
What does a sauna warranty actually cover?
It varies more than the headlines suggest. 'Lifetime' often means seven years or excludes something. The terms that matter are heaters and controls; check whether you pay shipping and labor on a claim. Full guide →
Can I move my sauna if I move house?
Infrared cabins and tents, easily; they come apart in an hour. Barrels and cubes can be disassembled but it's a project. Built-in rooms stay. Full guide →
Does a home sauna add value to a house?
A well-built outdoor or built-in sauna is a selling feature in cold climates and wellness-minded markets, though you rarely recoup the full cost. A freestanding infrared cabin is treated as furniture and goes with you. Full guide →
Does an infrared sauna smell?
New cedar smells strongly for a few weeks and faintly after. Hemlock, basswood and eucalyptus have little scent. Any cabin smells of hot wood the first few sessions; it fades. Full guide →
Pairing it with cold and light
Do I need a cold plunge too?
No, but the contrast is where many owners say the magic is. Start with cold showers; move to a tub if you keep it up. A chiller tub costs $1,200-$10,000 and $8-$45 a month to run. Full guide →
Should I get a sauna with red light built in?
Nice to have if it's a real panel with published wavelengths (660/850 nm) and irradiance; otherwise a $300-$600 standalone panel is a more controllable dose for less money. Full guide →
