Infrared vs traditional saunas: which is right for you?

The first real fork in choosing a home sauna is infrared versus traditional, and it matters because the two heat you in completely different ways — with knock-on effects for installation, running cost and the whole feel of a session. This guide explains the difference, then gives you a framework for deciding.

Two fundamentally different experiences

A traditional sauna heats the air — often to 170–195°F — with an electric or wood-fired heater topped with stones. You can pour water on the hot rocks to create a burst of steam (löyly), which raises the perceived heat and humidity. It's the classic, intense, social sauna experience.

An infrared sauna heats your body directly with infrared light rather than heating the air around you. Air temperatures stay lower — typically 120–160°F — so the session feels gentler and you can stay in longer. There's no steam. Many people who find high heat uncomfortable prefer infrared for exactly this reason.

Neither is "better." They're aimed at different preferences, and the right answer depends as much on your home as on your taste.

Installation is the deciding factor for many buyers

Here's the practical reality that often makes the decision: most infrared cabins for one or two people run on a standard 120V household outlet, so you can set one up in a spare room in an afternoon. Traditional electric heaters of any real size need a dedicated 240V circuit, which means an electrician and, often, an inspection.

If you can't easily add a 240V circuit where the sauna will go — a common situation in apartments, condos and finished basements — that constraint alone frequently points to infrared. Our best 120V saunas shortlist exists precisely for buyers in that situation.

Side by side

Full-spectrum vs far-infrared

Within infrared there's a further choice. Far-infrared is the most common and produces a comfortable, sweat-inducing heat. Full-spectrum cabins add near- and mid-infrared, which some brands associate with skin and recovery claims. The Clearlight Sanctuary 2 and Sunlighten mPulse are full-spectrum; the Clearlight Premier IS-2 is far-infrared and costs meaningfully less.

For most people chasing relaxation and a good sweat, far-infrared alone is plenty. Full-spectrum is worth it mainly if you specifically want near-infrared.

Warm-up, running cost and comfort

Infrared cabins warm up faster (often 10–20 minutes) and cost a little less to run. Traditional saunas take longer to reach temperature and cost slightly more, but deliver the high-heat, steam-capable session enthusiasts want. Neither is expensive to run relative to major household appliances — the running-cost gap between the two is real but small.

If your main goal is to actually use it on a busy weeknight, warm-up time matters more than people expect. A cabin that's ready in fifteen minutes gets used; one that needs forty-five often doesn't.

Materials, size and where it goes

Common woods include cedar (aromatic, naturally weather-resistant), hemlock, and basswood (a good low-allergen choice). Confirm capacity honestly — a "two-person" cabin is cosy for two — and check the footprint and ceiling height.

Traditional barrels like the Almost Heaven Grandview are designed for outdoors; most infrared cabins are indoor, though some are weatherproofed for outdoor use in milder climates. If the sauna is going in the backyard, start with our best outdoor saunas shortlist.

So which should you choose?

• Go traditional if you want authenticity, very high heat and steam, you're happy to install a 240V circuit, and ideally you have an outdoor spot.
• Go infrared if you value convenience, gentle heat, quick warm-up and the ability to plug into a normal outlet indoors.
• Go full-spectrum infrared only if you specifically want near-infrared on top of a good sweat.

When you've picked a type, compare two finalists directly — for instance Clearlight Sanctuary 2 vs Sunlighten mPulse — and if budget is the constraint, see how much a home sauna costs for the full price picture.
