Do infrared saunas use a lot of electricity?

Infrared panels are built to warm your body directly with radiant heat, rather than warming the entire volume of air in the cabin and a bed of rocks the way a traditional sauna heater does. That difference in job description is the whole story: a traditional heater is doing more total heating work per session, which is why it is built with a much heavier power draw and, in most homes, needs a dedicated circuit to support it safely.

Infrared panels, doing a smaller job, are built with a correspondingly smaller draw. That is not a marketing claim — it follows directly from what each type of heater is actually doing to the air and to you. It is the central reason infrared is usually the easier of the two to fit into an existing home’s electrical setup, and why it tends to come up first in conversations about a low-friction first sauna. For the fuller comparison of the two heating approaches beyond just electricity, our infrared vs. traditional sauna guide covers the experience side as well.

It also helps to think about how quickly each type reaches a usable temperature. Because an infrared panel is not trying to heat an entire volume of air before you feel anything, cabins tend to warm up faster from a cold start than a traditional cabin does. That matters for electricity in a practical way: the heater is not running at full draw for as long per session, which is part of why the gap between the two types is bigger in real-world use than the heater specifications alone might suggest.

This same logic explains why an outdoor infrared cabin is not automatically a bigger electrical commitment than an indoor one. The draw comes from the heater’s job, not from whether the cabin sits in a yard or a basement, so a well-sized outdoor infrared unit can be just as electrically approachable as its indoor equivalent, provided the outdoor outlet itself is properly weatherproofed. Our best outdoor infrared saunas roundup is worth a look if that is the direction you are considering.

Because the power draw is comparatively modest, many one- and two-person infrared cabins are designed to plug straight into a standard household outlet — the same kind of circuit that runs a hair dryer, a space heater, or a toaster oven, rather than requiring an electrician to install anything new. That is a meaningful practical advantage over a traditional sauna heater, which typically cannot make that claim.

This is not universal, though. Larger infrared cabins, models with extra features, or units installed alongside other equipment on the same circuit can draw enough that a standard outlet is not appropriate, and the manufacturer’s listed requirements should always be the final word, not a general assumption from this page. Our which saunas plug into a normal outlet guide goes through this in more detail across sauna types, and our electrical hub has the technical side, including does a sauna need a dedicated circuit.

There is a genuine practical upside to this beyond just avoiding an electrician’s bill. Owning something that plugs directly into an existing outlet means you can move it, reposition it in a room, or take it with you if you relocate, without the sauna being tied to a piece of wiring that was custom-installed for one specific spot in one specific home. For renters or anyone who expects to move within a few years, that flexibility is worth weighing alongside the electrical draw itself.

The heater’s baseline efficiency is only half of what determines your actual cost. The other half is entirely about you: how long each session runs, how many sessions you take in a week, and what your utility charges for electricity in your area, which varies widely by region. Two households with the identical cabin can see genuinely different numbers on their bill purely because of these habits and local rates.

This is exactly why we are not going to hand you a specific dollar figure on this page — a single number here would be honest for approximately nobody’s actual home. What we can tell you is the shape of it: infrared running cost sits in the realm of a noticeable but modest add-on to a monthly bill for typical use, closer to running another regular household appliance than to a major new expense. For the real arithmetic applied to your own habits, our cost to run an infrared sauna guide and cost to run a sauna guide walk you through it properly.

One more honest point worth making: electricity is rarely the deciding factor in whether a sauna habit is worth it financially. The purchase itself, and for some setups any electrical or foundation work, are the bigger numbers in the whole picture. Running cost tends to be the smallest recurring line item once the sauna is actually installed, which is worth keeping in perspective when this question feels like the main hurdle before buying.

Ranked purely on electrical draw and nothing else, the general order runs roughly like this: sauna blankets tend to draw the least, since they are heating a small enclosed space directly around your body rather than an entire room. Infrared cabins come next, warming a full room but with a lighter-duty heating approach. Traditional heaters draw the most, since they are heating both the air and a mass of rocks to a higher temperature.

• Sauna blankets— smallest space to heat, generally the lightest draw of the three.
• Infrared cabins— a full room, but radiant heat aimed at the body rather than the whole volume of air.
• Traditional heaters— heating air and rocks to a higher temperature, generally the heaviest draw and most likely to need a dedicated circuit.

This ranking is about electrical draw specifically, not about which is the better sauna — that is a separate, more personal question covered in our sauna blanket vs. infrared sauna guide and our barrel sauna vs. infrared sauna guide.

It is worth noting this ranking can shift with usage patterns rather than staying fixed. A sauna blanket used daily for long sessions can add up to more total electricity over a month than an infrared cabin used only occasionally, even though the blanket draws less in any single session. Total draw at any one moment and total cost over a month are related but not the same measurement, and it is the second one that actually shows up on a bill.

“Usually a normal outlet is enough” is a general pattern, not a guarantee for every model. Larger multi-person infrared cabins, units with extra heating panels, or add-on features like chromotherapy lighting or built-in sound systems can push a unit’s draw high enough that the manufacturer specifies more than a standard outlet can safely support. Near-continuous or back-to-back daily use is also a different situation from occasional weekend sessions, worth mentioning to an electrician if that is your plan.

The reliable way to know for certain is the specification sheet for the exact model you are considering, checked against your home’s actual outlet and circuit before you buy — not a general rule of thumb from any guide, including this one. When a new circuit is a real possibility, our sauna electrical requirements guide covers what an electrician will want to know, and do you need a permit for a home sauna is worth a read before any electrical work begins.

If you are shopping specifically to stay under that ceiling, it is worth filtering your shortlist to smaller, simpler cabins rather than assuming every infrared model qualifies by default. A one- or two-person cabin without add-on features is the safest bet for staying on a normal outlet, and it is also, not coincidentally, usually the most sensible size for a first sauna in the first place.
