Two saunas can both promise a good sweat and still be built on opposite principles. An infrared sauna warms your body directly with light while the air stays around 120 to 150F, so it feels tolerable and many models plug into a normal wall outlet. A traditional Finnish-style sauna heats the air itself with a heater and rocks to 175 to 195F, then you ladle water over the stones for steam, and it carries the longest published research record of the two.
Here is the direct answer before the details. Choose infrared if you want a gentler heat you can sit in longer, the easiest install, and control over EMF exposure. Choose traditional if you want the hottest, most authentic loyly experience and the deepest research base behind it. The rest of this guide names a specific pick for each buyer type, with verified prices.
Quick answer
- Small space, renter, or heat-sensitive: the Sun Home Equinox 2-person at $5,999-6,799, because it runs full-spectrum infrared on a standard 120V outlet with no electrician.
- Lowest-EMF priority: the Clearlight Sanctuary 2 at $5,495-9,295, because its True Wave panels post among the lowest EMF readings in the category.
- Hottest authentic experience with the deepest research base: the Sweat Kingdom traditional line from $5,795, because Finnish-style heat at 175-195F is what the long-running cohort studies examined.

Two structural notes on the table. The infrared air temperatures reflect how those cabins heat your body directly at a lower air temperature; the traditional 175-195F reflects heating the air itself, so the numbers are not measuring the same thing. Pricing spans reflect configuration and size within each line.
Best infrared for a spare room or a rental
The Sun Home Equinox 2-person is the pick when the deciding factor is install. It is a full-spectrum infrared cabin that runs on a standard 120V wall outlet, so it goes in a spare room with no electrician and no 240V circuit. That removes the single biggest barrier that stops most people from putting a sauna at home. It also measures around 0.5 mG EMF, which matters because infrared panels sit close to your body.
Where it gives ground: it heats gently, around 120 to 150F, so if you specifically want the searing 190F-plus experience of a Finnish room, infrared will feel milder by design. It is also an infrared cabin, which means it sits outside the long Finnish-style research record discussed below. Who it is for: renters, apartment dwellers, heat-sensitive users, and anyone who wants to skip an electrician.
Best infrared for the lowest EMF
The Clearlight Sanctuary 2 is the choice when EMF is your first filter. It uses Jacuzzi-owned True Wave full-spectrum heaters and posts among the lowest EMF readings in the category. If you have read enough about infrared to worry about field exposure, this is the brand that answers the question directly rather than asking you to assume.
Where it gives ground: the price band runs wide, $5,495 to $9,295, so the entry point is competitive but a larger configuration climbs quickly. Like every infrared cabin here, it delivers a gentler heat than a traditional room. Who it is for: buyers who treat published low-EMF readings as non-negotiable and want a full-spectrum panel from an established parent company.
Best infrared with red light and app control
The Peak Saunas Fuji 2-person folds two devices into one cabin. It is a full-spectrum infrared sauna with a built-in red light wall and app control, all on a plug-in setup at $7,950-8,450. If you were otherwise going to buy an infrared sauna and a separate red light panel, consolidating the footprint is the argument here.
Where it gives ground: it costs more than the entry infrared options, and the red light wall is a feature you should actually intend to use, not a line item you pay for and ignore. Who it is for: buyers who want infrared plus red light in one enclosure with app control, and who have room in the budget above the base tier.
For the premium programmable route, the Sunlighten mPulse Empower sits at the top of the infrared range at $13,995-16,995 with programmable full-spectrum control. It is the pick when budget is not the constraint and you want the most configurable infrared experience.
Best traditional for the hottest, most researched experience
The Sweat Kingdom line is the traditional-side answer. It is Finnish-style, built in cedar and hemlock, and runs 175-195F with electric or wood-burning heater options that are Harvia and HUUM compatible. The range spans the Sweat Barrel at $5,295, the Summit at $7,495, and the SK 110 flagship at $17,995, so the mid-tier Summit is the natural starting point and the SK 110 is the statement build.
This is also where the research record lives. Traditional Finnish-style sauna use at 175-195F carries the longest published research base, including the Laukkanen KIHD observational cohort studies, which examined associations between frequent sauna bathing and cardiovascular and all-cause mortality. Read that carefully: the research studied patterns of hot Finnish-style bathing within a population and reported associations. It is not a promise of a personal result, and most of it centers on traditional heat rather than infrared.
Where it gives ground: traditional heaters need more from your space and setup than a 120V infrared cabin, so the install is a bigger commitment, and the wood-burning option adds ventilation and fuel considerations. The 175-195F heat is the point, but it is also less forgiving for anyone who finds high heat hard to tolerate. Who it is for: buyers with the room and the appetite for an authentic, steam-capable Finnish experience and the research legacy attached to it.
How to choose
- You rent, lack a 240V circuit, or want no electrician: the Sun Home Equinox 2-person at $5,999-6,799 on a standard outlet.
- Low EMF is your top priority: the Clearlight Sanctuary 2 at $5,495-9,295.
- You want infrared plus a red light wall and app control: the Peak Saunas Fuji 2-person at $7,950-8,450.
- You want the most configurable premium infrared: the Sunlighten mPulse Empower at $13,995-16,995.
- You want hot, authentic Finnish-style heat and the deepest research base: the Sweat Kingdom line, Summit at $7,495 or the SK 110 flagship at $17,995.
Bottom line
There is no single winner, because the two sauna types solve different problems. If tolerability, easy install, and EMF control matter most, go infrared: the Sun Home Equinox for a plug-in room, the Clearlight Sanctuary 2 for the lowest EMF, and the Peak Saunas Fuji if you want red light built in. If you want the hottest authentic experience at 175-195F and the deepest research record, the traditional Sweat Kingdom line is the one, with the Sunlighten mPulse Empower as the premium programmable infrared alternative. Match the heat, the install, and the research angle to how you actually live, and the choice makes itself.

What is the real difference between an infrared sauna and a traditional sauna?
An infrared sauna uses light to heat your body directly, so the air stays around 120-150F and feels gentler. A traditional Finnish-style sauna heats the air with a heater and rocks to 175-195F, then you pour water for steam. Infrared is easier to tolerate and often plugs into a 120V outlet; traditional delivers the hottest, most authentic experience.
Does an infrared sauna need a 240V outlet or an electrician?
Not always. The Sun Home Equinox 2-person, at $5,999-6,799, runs on a standard 120V wall outlet, so it installs in a spare room with no electrician and no dedicated 240V circuit. That plug-in setup is the main install advantage of infrared over traditional Finnish-style saunas, which use higher-output heaters that typically require more electrical work and dedicated space.
Which sauna type has more scientific research behind it?
Traditional Finnish-style sauna use at 175-195F carries the longest published research base. That includes the Laukkanen KIHD observational cohort studies, which examined associations between frequent sauna bathing and cardiovascular and all-cause mortality. That research studied habits within a population, not a guaranteed personal outcome, and most of it centers on hot Finnish-style bathing rather than infrared.
Is EMF a real concern with infrared saunas?
EMF exposure is a common question with infrared because the heating panels sit close to your body. Low-EMF designs address it: the Clearlight Sanctuary 2, at $5,495-9,295, posts among the lowest EMF readings in the category, and the Sun Home Equinox measures around 0.5 mG. If low EMF is your top priority, prioritize a brand that publishes its readings rather than assuming all infrared cabins are equal.
Can you get red light therapy and app control in an infrared sauna?
Yes. The Peak Saunas Fuji 2-person, at $7,950-8,450, is a full-spectrum infrared cabin with a built-in red light wall and app control on a plug-in setup, combining two devices in one footprint. For a premium programmable route, the Sunlighten mPulse Empower runs $13,995-16,995. Traditional Finnish-style cabins focus on heat and steam and do not bundle red light panels.
