Infrared Sauna Cost

The short answer

A full-size infrared sauna for the home is a big purchase, and the sticker price is only part of it. You also pay for delivery, you may pay for assembly, you may need an electrician, and you pay a little for every session. This page adds those pieces up so you can compare the real cost of owning one with the number on the product page.

We cover one company, Plunge, because that is the one whose pages we read for this guide. Its prices below are as read on 2026-10-28 from Plunge's product pages and can change without notice. We did not test any sauna, and we do not print other brands' prices, because we did not read their pages for this guide. If you want the full picture of the product before the money, start with the Plunge infrared sauna review. If you are still choosing a type of sauna, our pick for the best infrared home sauna explains how we weigh the options.

Disclosure: we promote Plunge and earn a commission if you buy through our links. That does not change the prices you see here, which come from Plunge's own pages.

What Plunge charges, as read 2026-10-28

Plunge sells two infrared models in the range we read. Prices are per Plunge, as read 2026-10-28.

In plain terms:

• The Infrared Sauna (Standard) is listed at $7,190, shown by Plunge as reduced from $7,690. It runs on a 120V outlet and is described as plug-and-play. Plunge lists a top temperature of 160 degrees F.
• The Infrared Sauna Pro is listed at $7,490, with $7,990 crossed out as a comparison value. It needs a 240V, 20A dedicated circuit with a NEMA 6-20 outlet. Plunge lists a top temperature of 175 degrees F. Plunge also describes an optional red light add-on for the Pro. We did not confirm its price, so every total below leaves it out.

Both models share the same basic build per Plunge: far-infrared panels plus full-spectrum incandescent towers, a Canadian hemlock cabin, app-controlled preheating and scheduling, Bluetooth speakers and chromotherapy lighting. If the heater mix is new to you, what "full spectrum" means covers it.

The "was" prices matter less than they look. Plan around the current price, and expect it to move. Plunge also lists a $500 automatic discount in its offers. We could not tell from the pages whether that discount is already inside the listed price or comes off it, so we do not subtract it anywhere on this page. Check the cart before you decide.

What drives the price of an infrared sauna

We did not read enough independent pricing pages to quote a market range, so we will not print one. What we can do is explain the factors that push any infrared sauna up or down, so you can judge a quote from any seller.

Size and capacity. More interior volume means more cabin wood, more heaters and a heavier crate. Plunge lists its Standard model at about 540 lb on the standard-model page, which tells you this is furniture-scale equipment, not an appliance you carry in alone.

Heater type and count. Panels, towers and the mix between them change the cost of the heating system. A setup with both far-infrared panels and incandescent towers, as Plunge describes, costs more to build than panels alone. Whether the extra heat types feel better to you is a personal call.

Wood and construction. Cabin material, joinery and finish all add cost. Plunge says its hemlock cabin uses no toxic adhesives or resins. That is Plunge's statement, and we did not verify it.

Electronics and extras. App control, speakers, lighting and optional red light add cost without adding heat.

Electrical requirements. A model that plugs into a standard outlet saves you an electrician. A model that needs a dedicated 240V circuit does not. This is the cost people forget, and we return to it below.

Electricity: a worked example

Running an infrared sauna costs far less than buying one. Here is the arithmetic, with every assumption stated so you can swap in your own numbers.

The wattage problem. We opened both Plunge product pages on 2026-10-28 looking for the sauna's wattage. Neither states it. The Pro page gives only "240V, 20A dedicated circuit, NEMA 6-20" and the Standard page gives only its outlet and circuit requirement. A circuit rating tells you the most the wiring can carry, not what the sauna draws in use. So we do not claim a Plunge wattage anywhere.

Instead, this is a clearly labelled round-number example: a 1,500 W heater running for 45 minutes. It is an illustration, not a Plunge specification. If you buy, look for the wattage in the manual or ask the seller, then redo the sums below.

The rate. The U.S. Energy Information Administration reports an average U.S. residential electricity price of 18.16 cents per kilowatt-hour for August 2026 (Electric Power Monthly, Table 5.6.A, released 2026-10-23). The same table shows 17.57 cents for August 2025. Your own rate will differ by state and by utility, so read your bill.

Per session:

• 1,500 W = 1.5 kW
• 45 minutes = 0.75 hour
• Energy: 1.5 kW x 0.75 h = 1.125 kWh
• Cost: 1.125 kWh x $0.1816 = $0.2043, or about 20 cents per session

Per year, at three sessions a week:

• Sessions: 3 x 52 = 156
• Energy: 156 x 1.125 kWh = 175.5 kWh
• Cost: 175.5 kWh x $0.1816 = $31.87, or about $32 per year

Over five years, holding the rate flat: $31.87 x 5 = $159.35, or about $159.

Two cautions. First, heating up before you get in uses energy too, and our example counts only the 45 minutes. Plunge describes app-controlled preheating, so a preheat of, say, 15 extra minutes at the same draw would add 1.5 kW x 0.25 h = 0.375 kWh, or about 7 cents per session. Second, a heater cycles on and off to hold a temperature, so the real draw may be lower than its rated wattage for part of the session. Treat the example as a rough guide, not a bill.

Even at double our example wattage, a year of regular use costs tens of dollars, not hundreds. Electricity is not what decides this purchase.

Delivery, assembly and setup

Delivery. Plunge lists standard curbside delivery at $250 to the lower 48 states, as read 2026-10-28. Curbside means the crate arrives at the edge of your property, not in the room. With a crate this heavy, plan for helpers or a hired crew to move it inside. We did not find a price for inside delivery on the pages we read.

Assembly. Plunge states about one hour for assembly. If you would rather not do it yourself, Plunge lists a professional assembly service. As read, the Standard page shows the service at $880, regularly $1,880, and the Pro page lists $1,000 off professional assembly. Those figures come from two pages that frame the offer differently, so we print them only as read and treat the $880 as the planning number. Confirm the final assembly price in your cart.

Electrical work. The Standard model uses a 120V outlet. The Pro needs a 240V, 20A dedicated circuit with a NEMA 6-20 outlet. If you do not already have one where the sauna will sit, an electrician has to add it. We did not find a price for that work, and it varies by house and region, so we leave it out of the table below. Get a quote before you order the Pro. Ask a licensed electrician about the circuit rather than guessing.

Financing

Plunge lists 0% APR financing for up to 36 months through Bread Pay, subject to credit approval, as read 2026-10-28. At 0% APR, spreading $7,190 over 36 months comes to about $199.72 a month, and $7,490 comes to about $208.06 a month. Those are plain divisions of the listed price. They are not a quote, and they ignore delivery and assembly. Your approval, terms and monthly payment come from the lender, so read them at checkout.

Warranty and what it is worth

Per Plunge, as read: 5 years on cabinetry and heaters, 2 years on electronics and controls, and 1 year on glass and power supplies. Plunge also lists an optional 2-year extended coverage, and a complimentary extended warranty with a $399 value among its offers.

The useful way to read a warranty is by part. The heaters and cabinet have the longest cover. The parts with the shortest cover, the glass and power supplies, are the ones that may fail first or cost most to ship. Neither page we read stated a trial period or a return policy. Read both at checkout before you pay, since a sauna this size is hard to return even when a policy exists.

Five-year cost, Plunge only

This table adds the purchase price, the $250 delivery and five years of electricity from the worked example above ($159.35). Assembly is shown as an option, not assumed. Everything is per Plunge, as read 2026-10-28, and the electricity row rests on our labelled 1,500 W example, not on a Plunge wattage.

The arithmetic, line by line:

• Standard: $7,190 + $250 = $7,440. Add $159.35 and you get $7,599.35, shown as $7,599. Add $880 and you get $8,479.35, shown as $8,479.
• Pro: $7,490 + $250 = $7,740. Add $159.35 and you get $7,899.35, shown as $7,899. Add $880 and you get $8,779.35, shown as $8,779.

What the table leaves out: the $500 automatic discount (unclear whether it is already in the price), any electrician cost for the Pro's 240V circuit, the optional extended coverage, the red light add-on, sales tax, and any financing cost beyond 0% APR.

The gap between the two models over five years is $800 on the listed price, since delivery and electricity are the same in our example. That gap buys the Pro a higher listed top temperature and a 240V requirement. Whether a 175 degree F top end matters to you is a question of how hot you like it. Our guide to infrared and traditional saunas compared helps you decide how much heat you actually want.

Where Plunge fits, and where it does not

Plunge fits you if you:

• have a budget above roughly $7,000 and want a finished indoor cabin with a stated warranty
• have space and a floor that can take a roughly 540 lb unit
• want the Standard on a normal outlet, or can add a 240V circuit for the Pro
• care about the low EMF rating Plunge states: a near-zero EMF rating, 0.1 mG per its Trifield reading. That is Plunge's own reading, not an independent one. Our guide to low EMF infrared saunas shows how to read that kind of claim.

Look elsewhere if you:

• have a budget under about $3,000, since neither Plunge model comes close
• want an outdoor install, which we did not find Plunge's pages to cover
• prefer a blanket or portable unit, which is a different product
• have no 240V circuit and do not want to add one, in which case the Pro is out and the Standard is the only option

We promote Plunge and earn a commission when you buy through our links. That is why this guide covers one company, and why it says plainly who should walk away.

If you have a medical condition, are pregnant, or take medicines, ask a doctor before you use any sauna. Cost is the smaller question, and the infrared sauna benefits article shows how thin the evidence is for some of the reasons people buy.

FAQ

How much does an infrared sauna cost to run?

With our example of a 1,500 W heater for 45 minutes at the EIA's August 2026 national residential average of 18.16 cents per kWh, a session costs about 20 cents. At three sessions a week, that is about $32 a year. Plunge's pages do not state the sauna's wattage, so the wattage is our assumption, and your rate will differ.

Do I need an electrician for a Plunge sauna?

Per Plunge, the Standard model uses a 120V outlet and is described as plug-and-play. The Pro needs a 240V, 20A dedicated circuit with a NEMA 6-20 outlet. If you do not have that circuit, a licensed electrician has to install it. We did not find a price for that work.

Is delivery included?

Plunge lists standard curbside delivery at $250 to the lower 48 states, as read 2026-10-28. It is a separate line from the sauna price in our table.

Is assembly included?

No price on the pages we read bundles it. Plunge states about one hour for assembly and lists a professional assembly service at $880 on the Standard page, regularly $1,880. The Pro page lists $1,000 off the service. Confirm the final figure in your cart.

Can I finance it?

Plunge lists 0% APR financing for up to 36 months through Bread Pay, subject to credit approval, as read 2026-10-28. Terms and approval come from the lender.

Can I return it?

The pages we read did not state a trial period or a return policy. Read the policy at checkout before you pay.

Before you buy

Add the listed price, $250 delivery, an electrician if you want the Pro, and assembly if you want it done for you. Then run your own wattage and rate through the electricity sums above. The result for either Plunge model lands between about $7,500 and $9,000 over five years on our assumptions, before the items the table leaves out.

If that fits your budget and your space, check the current price and offers on Plunge's own page, as they change.
