The first question with an infrared sauna isn’t which brand. It’s how many people will sit in it, because that sets the footprint, the plug, and most of the price.
This page sorts the infrared cabins in our catalog by size and picks out what stands out in each group. For heaters, EMF claims, and circuits, start with the infrared sauna buying guide.
Short answer: for one person, the Finnmark FD-1 ($4,695) reaches 170°F on a household plug. For a tight budget, the 1-to-2-person Dynamic Barcelona and Avila cost $1,999. For two adults, the Dynamic Andora ($2,210.99) is the lowest-priced 2-person cabin we list, and the Health Mate Enrich 2 ($5,300) has a lifetime warranty. For four, the Finnmark FD-3 ($6,495) needs a 240V circuit.
One person
| Cabin | Outside footprint | Power | Top heat | Warranty | Price |
|---|---|---|---|---|---|
| Finnmark FD-1 | 38” x 38” | 120V/15A, 1,750W | 170°F | Limited, term not stated | $4,695 |
| Sunlighten Signature I | 37.8” x 39.8” | Dedicated 120V/20A, 1,350W | Not in our data | 7 years | $4,999 |
| Clearlight Premier IS-1 | 40” x 44” | 120V/15A plug, 1,370W | Not in our data | Lifetime, residential | $5,799 |
You get the most heater per person here. The Clearlight puts heaters on five surfaces, including under the floor. The trade-off is that only one of you can use it at a time.
One to two people
The Dynamic Barcelona and Dynamic Avila both cost $1,999 at Select Saunas, measure 39” x 36” outside, and are 36” wide inside. Both run on a 120V/15A plug and reach 140°F. The Avila adds a seventh carbon panel under the bench.
Here’s what the spec sheet won’t tell you. “1-2 person” at 36 inches wide is a one-person cabin that two people can share if they sit close. Measure your shoulders together before you count on it.
Two people
| Cabin | Outside footprint | Power | Top heat | Warranty | Price |
|---|---|---|---|---|---|
| Dynamic Andora | 47” x 42” | 120V/15A | 140°F (Home Depot) | Not in our data | $2,210.99 |
| Maxxus Seattle | Not on listing | 120V/15A | Not on listing | Not on listing | $2,299 |
| Durasage 2-Person Carbon | 47.6” x 41.7” | 120V, 1,700W | About 140°F | 12 months | $3,295 |
| Health Mate Enrich 2 | 47.25” x 43.5” | 120V/15A, 1,780W | Not in our data | Lifetime unit, 10 years wood | $5,300 |
| Clearlight Sanctuary 2 | 51.75” x 47.75” | 120V/20A | Not in our data | Limited lifetime, original owner | Quote only |

The cheapest two are close on price, but the Andora publishes its size and top heat, and the Seattle listing gives neither. The Enrich 2 costs $3,089 more than the Andora and adds a lifetime warranty on the unit and a built-in red light array.
Four people
The Finnmark FD-3 is 72” x 46” outside, reaches 170°F, and draws 3,150W, which needs a dedicated 240V, 15A circuit. At $6,495 it is the only 4-person infrared cabin in our catalog.
Run the numbers per seat: $6,495 for four is about $1,624 a seat, against $4,695 for the FD-1’s single seat.
Outdoors, or no cabin at all
The Sunray Burlington ($3,790) is built for a patio, with a weather cover and a 7-year structural warranty, on a 120V/20A plug. The Sunlighten Solo ($1,999) is a portable dome rated to 150°F that stores in a closet.
How hot is hot enough?
Cleveland Clinic gives 110 to 135°F as the typical range for infrared saunas. Every cabin above that lists a top temperature reaches at least 135°F, the top of that range, so a higher maximum isn’t the thing to pay for.
My rule of thumb: buy for the number of people who will use it most days, not for the occasional guest. Each step up in size adds width, weight, and sometimes a bigger circuit.
To compare five cabins under $5,000 side by side, see our infrared saunas under $5,000.
Bottom line: one person, the FD-1 or Signature I; a budget, the Barcelona or Avila; two adults, the Andora or Enrich 2; four, the FD-3. Check the plug before you check the price.
