How to Choose an Infrared Sauna for Your Home

Capacity is the first fork in the road, because it sets the footprint, the weight, and the price. A one-to-two person cabin suits a single regular user with the occasional guest. A two-person cabin gives two adults room to sit without negotiating elbows. A three-person cabin is the one to choose if sessions are usually shared, or if you want the option of lying down.

• The Retreat One — 1-2 people, 47"D × 39"L × 75"H, 725 lbs.
• The Retreat Two — 2 people, 47"D × 41"L × 75"H, 985 lbs.
• The Retreat Three — 3 people, 47"D × 60"L × 75"H, 1,250 lbs.

Buying one size up is usually the regret-free choice when the room allows it; buying two sizes up rarely is, because the cabin heats a volume you are not using.

Take the cabin dimensions and add a few inches behind and to the sides for airflow and for the power cord to leave the unit without being pinched. Check the ceiling height as well — every cabin on our list stands 75 inches tall, so a low basement soffit matters.

Floor and access

The floor needs to be level and able to carry the assembled weight plus occupants. Just as important is the route in: measure doorways, stair turns, and hallway widths. The cabin arrives as flat panels rather than a single box, which makes tight routes manageable, but the panels are still heavy enough to need two people.

Sauna listings often bury voltage in a specification table. It is the line that decides whether you are using the sauna the week it arrives or waiting on a contractor. Every sauna on our list runs on a standard 110V household outlet, so there is no dedicated circuit and no electrician in the timeline.

Give the sauna its own outlet where you can, and skip extension cords.

All three cabins are built from Canadian hemlock — a low-resin, hypoallergenic wood that resists warping over years of heat cycling. Far-infrared electric panels do the heating; the number of panels rises with cabin size, from two in The Retreat One to three in The Retreat Two.

Look at the door too. The Retreat Two uses 8mm tempered glass, which is worth noting if the cabin will sit somewhere you want to see into.

• Control type — simple digital controls on The Retreat One and Three, a touchscreen on The Retreat Two.
• Ambient extras — The Retreat Two adds built-in speakers, color light therapy, and an oxygen ionizer.
• Ventilation — The Retreat Three includes a ventilation window for fresh airflow during longer sessions.

None of these change how the cabin heats. Choose them on whether you will actually use them.

Lead time is typically 15-30 business days. Standard delivery is $500 curbside freight. White-glove in-home delivery and installation are available on request and priced separately. Assembly is a panel-by-panel job that a pair of people can finish in an afternoon with basic tools.

Put the three side by side on four lines only: capacity, footprint, panel count, and extras. Price follows capacity. If the room can take the larger footprint and sessions are ever shared, the larger cabin is the better long-term buy. If the sauna is squeezing into a spare corner or a primary bath, the compact cabin is the one that gets used.
