Most home infrared saunas run between $2,300 and $8,500 installed, and Angi’s 2026 home sauna guide puts the average buyer near $4,200. Size drives the number more than anything else, then wood quality, then whether the heat is far infrared only or full spectrum. The good news if you are shopping infrared instead of traditional: these run on a dedicated 120 volt 20 amp circuit, ordinary household power, so you are usually not paying an electrician to pull 240 volt service. Running one is cheap too. At Iowa electricity rates a half hour session costs about a quarter. Here is what moves the price, which size fits which room, and what the research actually supports.
Key Takeaways
- Infrared saunas typically run $2,300 to $8,500 installed, with the average buyer near $4,200.
- Infrared needs a dedicated 120 volt 20 amp circuit. Traditional saunas usually need 240 volt service and an electrician.
- A session costs about a quarter at Iowa electricity rates, so operating cost is almost never the reason people quit using one.
- Compare what a price includes. Bought direct, assembly is on you. We include install within about two hours of Spirit Lake.
- The evidence for infrared is real but thinner than the marketing, and one common claim has been specifically refuted.
What does an infrared sauna cost?
Between $2,300 and $8,500 installed for most people. That is the range in HomeGuide’s 2026 sauna cost guide, and Angi’s 2026 numbers put the average buyer near $4,200.
There are really three tiers under that range. Portable one and two person cabinets start around $1,500 and feel like it. The middle, call it $4,000 to $7,000, is where you get full spectrum heat, better wood, and the features people actually use daily. Above $7,000 you are buying larger three and four person cabins.
Where the comparison gets slippery is what a quoted price covers. Buy from an online listing and standard home delivery is usually included, but assembly is not. Master Spas says so plainly in their own shipping terms: the sauna arrives in multiple cartons of panels and on-site assembly is the buyer’s job. We carry the Sweaty GOAT line by Michael Phelps, and our pricing includes the sauna plus delivery and install if you are within about two hours of Spirit Lake. So a web price that looks lower is often a stack of boxes on your driveway and a Saturday you did not plan on.
Call us for a current number on any of the three. I would rather give you today’s price over the phone than have you find a stale figure on a page somebody forgot to update, which happens more than dealers like to admit.
What actually drives the price?
Size does most of the work, and it is not close. A two person cabinet and a three person corner unit are a different amount of wood, more heating panels, and a lot more shipping weight, so everything else on this list is small next to that one.
Wood is second. Species and grade move the number a lot, and clear knot free panels cost more than the same wood with knots in it. The Sweaty GOAT cabins use certified Canadian hemlock, which holds its shape instead of warping on you after a couple hundred heat cycles.
Then heat type, and this one is worth understanding because it explains a lot of the price spread across the market. Far infrared only is the baseline. Full spectrum adds near and mid wavelengths and costs more. The Sweaty GOAT models run ten HybridHeat Plus elements with full spectrum low EMF heating, which is why they sit in the middle of the market rather than down with the plug-in cabinets.
Features fill in the rest: chromotherapy lighting, wireless audio, air purification, a real control panel instead of a dial. What almost never drives the price on an infrared unit is electrical work, and that gap between infrared and traditional is worth its own section.
What does it cost to run?
Less than people expect, and this is the part nobody bothers to publish.
A traditional electric sauna generally wants 240 volt service on a dedicated circuit. That means an electrician, a permit in most places, and a real line item before you ever sit in it. Infrared does not work that way. The Sweaty GOAT models need a dedicated 120 volt 20 amp circuit, which is ordinary household power, on a NEMA 5-20 outlet. If one is already where the sauna is going, your electrical cost is zero.
One detail that saves a headache: the unit ships with a ten foot cord that exits from the back left of the roof, and the manufacturer says not to share that plug with anything else. So the outlet has to be reachable from up there and it has to be its own circuit. Worth knowing before you decide which wall the sauna goes against.
Operating cost is small as well. Iowa residential electricity runs in the neighborhood of 13 to 14 cents per kilowatt hour based on U.S. Energy Information Administration retail price data, well under the national average. A unit on a 20 amp circuit pulls somewhere around 1.5 to 1.8 kilowatts and heats up in 20 to 25 minutes. Half hour session, warm up included, and you are looking at roughly a quarter. Three sessions a week runs a couple dollars a month.
I bring that up because the cheapest sauna is the one you actually keep using, and what kills a purchase like this is friction. If you flinch every time you flip it on, it turns into a very expensive place to hang wet towels. I have seen that happen. Usually it is not the sauna’s fault.
Which size fits your room?
Measure the room before you fall in love with a model. I have watched that go the other direction more than once, and the conversation where somebody finds out their sauna will not fit through the door of the room they picked is not a fun one to have.
All three Sweaty GOAT models stand 75 inches tall and are rated indoor use only. Footprint is what separates them:
- MP2, 48 by 48 inches, seats two. Fits a primary suite, a spare bedroom, or a corner of a finished basement.
- MP3, 60 by 49 inches, seats three. Wants a home gym or a room with more width to give.
- MP3C, 59 by 59 inches, seats three in a corner shape. Takes the corner and leaves the middle of the room open.
Two things people forget. Leave clearance around the cabinet, not just the exact footprint. And because these ship as labeled panels, the path from your door to the room only has to fit the panels rather than the finished box, which works in your favor on a tight stairwell. Our team walks that path before the truck comes.
Indoor only is not a suggestion, either. Put one on a three season porch or out in an unconditioned shop and the temperature swings will find the wood and the electronics eventually. Around here that is not a maybe. If what you want is heat outdoors, tell us and we will talk about something else instead.
What does the research actually say?
We sell these, so read this section knowing that. I would still rather give you the honest version than the brochure version, because this category online is full of claims nobody can back.
Here is what holds up. Infrared saunas produce reactions similar to moderate exercise, sweating and a raised heart rate, at lower temperatures than a traditional sauna. That lower temperature is the practical advantage. Mayo Clinic describes infrared as an option for people who cannot take the heat of a regular sauna, and reports that no harmful effects have been found with infrared use.
Now the honest part. Asked whether the health benefits are clear, Mayo’s answer is a qualified maybe. Studies have found some evidence that saunas may help with several long-term conditions. Mayo also says larger and more exact studies are needed to prove those results.
A systematic review in Canadian Family Physician gets more specific. It found limited moderate evidence for far infrared sauna use in normalizing blood pressure and treating congestive heart failure, and fair evidence from a single study for chronic pain. It also found consistent evidence refuting the claim that far infrared saunas reduce cholesterol. If a salesman tells you a sauna will fix your cholesterol numbers, that is the exact claim the literature pushed back on.
One more distinction. The impressive long-term sauna research people quote, the Finnish work on cardiovascular outcomes, studied traditional high heat saunas, not infrared. The mechanisms overlap and the infrared research looks promising, but it is a smaller and newer body of work. Anybody flattening those two into one claim is selling you something.
Practical safety, which the manufacturer says too. Start lower and shorter and build as you tolerate it. Drink water. Keep sessions to about 30 minutes. Check with your doctor first if you are pregnant, trying to conceive, living with a condition that affects heat tolerance, or taking a medication that does.
What to check before you buy
- Measure the room and the delivery path, including doorways and stair turns.
- Confirm a dedicated 120 volt 20 amp circuit and a NEMA 5-20 outlet within reach of a ten foot cord.
- Ask what the quoted price includes. Cabin only, delivery, or delivery and assembly.
- Get the warranty in writing. Master Spas currently lists five years on the electrical components, meaning the control system and the heating elements, against defects in materials or workmanship.
- Ask who services it locally after the sale, and how fast they show up.
People skip that last one and regret it. A sauna is a wood box with electronics in it, and sooner or later something wants attention. Order from a listing and you are shipping parts back and forth and troubleshooting over email with somebody who has never seen your house. Buy it local and Cory drives out.
One thought on timing, and it is not a sales line. A sauna earns its keep in a northwest Iowa January, when it is dark at five and nobody is going outside for anything. That is the season you are buying it for. It is also the season you do not want to be waiting on a delivery in, so sorting it out in September beats sorting it out the week after Christmas.
Honestly, the best thing we have going at Midwest Spas & More is not something I can put in a paragraph. Our showroom is on Aurora Avenue in Spirit Lake and you can go sit in all three of these. Five minutes on the bench tells you more than any spec sheet I could write, and it settles the two person versus three person question faster than a tape measure will. While you are in there, take a look at the pergolas and patio covers too, since plenty of folks are working on the same backyard. To see the models or get a current price, schedule a call or just stop in.
FAQ
How much does an infrared sauna cost?
Most home infrared saunas run $2,300 to $8,500 installed, and Angi’s 2026 data puts the average buyer near $4,200. Size is the biggest driver, then wood quality, heat type, and features. Compare carefully, because an online price is often the cabin with assembly left to you, while a dealer price may include delivery and installation.
What is the difference between an infrared and a traditional sauna?
A traditional sauna heats the air, which then heats you, and runs hot enough that plenty of people find it hard to sit in. An infrared sauna heats your body directly, so it works at a much lower air temperature. In practice infrared is more comfortable for more people, and it does not usually require 240 volt electrical work.
Do I need special wiring for an infrared sauna?
You need a dedicated 120 volt 20 amp circuit with a NEMA 5-20 outlet, which is ordinary household power rather than the 240 volt service a traditional electric sauna typically needs. The unit ships with a ten foot cord that exits the back left of the roof, and the plug cannot be shared with another appliance. If a suitable circuit is already there, your electrical cost is nothing.
How much does it cost to run an infrared sauna?
Roughly a quarter for a half hour session including warm up, at Iowa’s average residential rate of about 13 to 14 cents per kilowatt hour. Even at three or four sessions a week you are looking at a few dollars a month. Operating cost is rarely why people stop using one.
What is the warranty on a Sweaty GOAT sauna?
Master Spas currently lists five years of coverage on the electrical components, which covers the control system and the heating elements against failure or malfunction from defects in materials or workmanship. Terms can change and can vary by market, so get the current warranty in writing at purchase and read what it covers.
Are the health claims about infrared saunas true?
Some hold up better than others. Mayo Clinic notes that studies suggest saunas may help with several long-term conditions but says larger and more exact studies are needed, and reports no harmful effects from infrared use. A Canadian Family Physician review found limited moderate evidence for blood pressure and heart failure, and evidence specifically refuting cholesterol reduction claims. Talk with your doctor about your own situation.
Can I put an infrared sauna in a garage or on a porch?
The Sweaty GOAT models are rated indoor use only, so a conditioned interior room is what they are built for. Cold swings, humidity, and dust are hard on the wood and the electronics. If you want heat outdoors, tell us and we will point you at something built for it instead of selling you the wrong box.
The best sauna is the one you actually sit in three times a week, so the size that fits your room and a price that does not make you flinch matter more than anything on a spec sheet. Come sit in one and see what you think. Or schedule a call and we will get you a current number.
