Infrared sauna vs sauna blanket

The short version: a one-person infrared cabin and an infrared blanket use the same kind of heat and cost a comparable amount to run. The cabin heats the air around your whole body, including your head and face, and it lives in your house permanently. The blanket heats the body it wraps, leaves your head out, rolls up into a cupboard and needs a washable insert. If you have the floor space, the cabin is the better experience. If you do not, the blanket is not a compromise so much as a different product.

Side by side

The head question

This is the difference people underestimate. In a cabin your head is inside the hot space, so the sensation is the one you know from a gym sauna — warm air on your face, a slightly labored breath, the thing that makes it feel like a sauna. A blanket heats you from the neck down. Plenty of people prefer that, particularly anyone who finds hot air on the face unpleasant, and it is why blanket sessions can run longer. But if what you want is the room, no blanket will give it to you. Our best sauna blankets roundup goes deeper on the format.

Temperature is not the whole story

A blanket's published maximum will usually look higher than a cabin's — the Lunix LX17 publishes 77–176 °F, while the Kanlanth cabin publishes 140 °F. Those numbers are not measuring the same thing. The blanket's figure is the temperature of a surface pressed against you; the cabin's is air temperature in a space you are sitting in. A 140 °F room and a 140 °F heating layer touching your skin are different experiences, and the second one will feel hotter sooner. Do not choose on the bigger number.

Running cost and power

Cabins at this size publish their draw — 905 W on the Kanlanth, 900 W on the DWKWE — so the arithmetic in our sauna running costs guide works directly. Blankets mostly do not publish a wattage at all, which is a real gap; the ones we have read describe temperature levels rather than power. As a class they draw less than a cabin, because there is far less volume to heat, but we are not going to put a number on something nobody publishes.

Upkeep: the bit nobody mentions before buying

• A blanket needs an insert. You sweat into it directly. Every blanket here is wipe-clean only, so a washable cotton or toweling insert is close to mandatory — our sauna blanket accessories page covers those.
• A cabin needs a wipe-down and a mat. Less often, and less urgently, but a bench that never gets wiped will eventually smell. A floor mat helps.
• Both need somewhere to dry. A rolled-up damp blanket is worse than a closed-up damp cabin, because there is no air in it at all.

Which one to buy

• A cabin, if you have a roughly 3 × 3 ft corner you can give up permanently, you want heat on your face, and you would rather sit than lie down.
• A blanket, if you rent, move often, share the space, or want the option of a session on the sofa. It is also the cheapest honest way into infrared.
• Both, if you already own a blanket and are upgrading. Blankets keep their job as the travel option — see best portable saunas.
