Infrared Sauna vs Steam Room
One you can plug into a wall outlet this weekend. The other is a waterproofing project with a steam generator. That gap decides this matchup for almost everyone shopping for home use.
For home use, pick an infrared sauna: it plugs into a standard outlet, runs a comfortable 120 to 140F (49 to 60C), and installs in a weekend. Choose a steam room only if you want humid heat near 110 to 120F and can handle waterproofing plus a steam generator. Infrared wins on cost and convenience for most buyers.
The verdict in one paragraph
For a home, pick the infrared sauna almost every time — it installs on a normal outlet, runs at a comfortable air temperature, and sits in the heat range (around 140°F) that the Tei 2016 Waon research used for cardiovascular benefit. Choose a steam room only if soothing humid heat is the whole point and you have a sealed, waterproofed space (or a gym membership) to deliver it — because building one at home is a real construction job, not a purchase.
Infrared sauna: gentle air, plug-and-play, some real data
Infrared saunas heat your body directly with radiant panels, so the cabin stays cooler — typically ~120–140°F — while you still sweat hard. That lower air temperature is why so many people who find traditional saunas oppressive tolerate infrared easily. On evidence, Tei 2016 studied "Waon therapy" — a far-infrared sauna around 140°F — and reported cardiovascular benefits (sources). It's a smaller literature than the dry-sauna cohort work, but it specifically supports infrared-range heat. The bigger selling point is logistics: units range from full cabins to one-person setups on a standard outlet. Browse tested options at best home saunas.

Steam room: humid comfort, hard install, thin research
A steam room runs around 110–120°F at near-total humidity. People love it for congestion and the enveloping spa feel — genuine comfort that an infrared cabin doesn't replicate. But at home it's the hard path: you need a sealed, waterproofed enclosure, a steam generator, and ventilation, or you invite mold and water damage. There's also less outcome research on steam rooms than on sauna of any kind, so we won't promise benefits the data doesn't support.

Frequently asked questions
Is an infrared sauna or steam room better?
They're built for different goals. Infrared saunas warm you at a gentler air temperature (~120–140°F) and are the easy home install — plug in, sit down. Steam rooms deliver soothing humid heat but are a serious building project at home. For cardiovascular benefit, the Tei 2016 Waon work supports infrared-style heat around 140°F; steam rooms have far less outcome research either way.
What temperature does an infrared sauna run at?
Lower than a traditional sauna — typically ~120–140°F. Infrared heats your body directly rather than super-heating the air, so a cooler cabin still produces a deep sweat. A steam room runs around 110–120°F but at near-100% humidity, which makes that lower number feel intense.
Can I install either one in an apartment?
An infrared sauna, often yes — small cabin or even a one-person tent that runs on a standard outlet. A steam room, almost never — it needs a fully sealed, waterproofed enclosure and a steam generator, which is impractical in a rental. This install gap is the deciding factor for most home buyers.
Which makes you sweat more?
Both can produce a heavy sweat, but it feels different. Infrared drives sweat from the inside via radiant heat at a comfortable air temperature; steam coats you so you can't tell sweat from condensation. Sweat volume isn't the benefit anyway — it's the heat stress and the habit that matter.
