What a sauna costs per session

Two numbers added together, and the second is the big one. The electricity is small and computable: a 3 kW traditional cabin for an hour at a 60% duty cycle is about 1.8 kWh, which at 18.31 cents per kWh works out around $0.33 a session. An infrared cabin at about 1.2 kW is roughly $0.13. The hardware is the larger half: whatever you paid, divided by how many sessions you will actually get out of it. Our table above does both halves at today's live prices over 780 sessions.

Almost certainly, eventually, and we are not going to quote you a studio price - they vary by city and by operator and we have not verified one, so inventing a figure would be fabrication. Here is the method instead: take your local studio's drop-in rate, and divide it into the total-per-session figure in our table. That gives you the number of sessions at which the home unit has paid for itself. Then ask the honest question, which is whether you will actually do that many. A unit used twice is the most expensive sauna in the world per session.

On electricity alone, very little - around $0.13 for an hour on the published wattage of the most completely specified cabin we compare, at the national average rate. Add the hardware slice and the number is dominated by the purchase price divided by your session count. That is why "infrared is cheap to run" is true and not very useful on its own: the running cost was never the obstacle. Our cost-to-run page for infrared works the electricity half in more detail and lets you substitute your own rate.

Because not one blanket in the category publishes a rated wattage, and we will not invent one. This is a heating appliance whose entire function is converting electricity to heat, and the specification that would let anyone compute its running cost is absent across the board. Any site quoting you a precise per-session figure for a blanket has picked a wattage to get there. What we can say honestly is that the draw is low - it heats you rather than a room - and that the hardware slice is the dominant cost, which the table above shows with the electricity column left blank.

Four, all stated rather than buried. A 60-minute session, covering heat-up and use. A 60% duty cycle, because a heater pulls rated power to reach temperature and then cycles to hold it - it does not draw full power for an hour. 3 sessions a week for 5 years, which is 780 sessions, for the hardware slice. And 18.31 cents per kWh, the US residential average, which is wrong for almost everybody - the same source puts individual states more than thirty cents apart. Change any of the four and the arithmetic moves; the point is that you can see which number to change.

No, and for a traditional cabin that is a real omission you should add yourself. A 240V stove cabin needs a dedicated circuit, and depending on your panel's spare capacity and the distance to the sauna that quote can be a meaningful fraction of the cabin's price. Add it to the hardware column and divide by the same session count. Infrared cabins, tents and blankets mostly plug in, which is the honest reason their total per session is lower than a stove cabin's by more than the wattage difference suggests.

Smaller than people expect on the heat side, which is the genuine advantage heat has over cold. A sauna has no water chemistry, no filter cartridges and no chiller; a traditional cabin's stones should be restacked and eventually replaced, and a wooden interior wants cleaning and occasional re-treatment. None of that is a per-session cost in any meaningful sense. The cold side of a recovery setup is the opposite, and our cold plunge running-cost page covers why.

That is the right question and it has your numbers in it rather than ours. Take the live total-per-session figure from the table, take your local studio's drop-in rate, and divide. The reason we present it this way rather than printing a break-even month is that the two variables that move it most are both yours: what a session costs near you, and how often you will really go. For what it is worth, the cheapest honest answer to "is this worth it" is usually not financial - it is that a sauna twenty feet from your bed gets used and one across town does not.
