Why Is There No Cheap Outdoor Sauna? The $1,399 Indoor vs $4,999 Outdoor Gap

If you have set a budget of two or three thousand dollars and you want the sauna in the backyard, the honest answer is that the two halves of that sentence do not currently meet, and not because anyone is padding a price.

• Our indoor floor is $1,399. Our outdoor floor is $4,999. Of the 143 saunas we list, 105 are indoor and 38 are outdoor, and exactly one outdoor model sits under $5,000: the Golden Designs St. Moritz barrel.
• The gap is a heat technology gap, not a weatherproofing surcharge. Zero of our 38 outdoor saunas are infrared. They are 27 traditional steam and 11 hybrid. Meanwhile 88 of our 105 indoor saunas are infrared, and infrared is where the entire sub-$2,500 shelf lives.
• Every one of the 30 saunas we list under $2,500 is indoor, infrared, and runs on a 120V household outlet. All thirty. There is no borderline case.
• Outdoor almost always means an electrician. 32 of the 38 outdoor models specify 240V, one specifies 120V, and five publish no electrical spec. Indoor is the reverse: 68 of 105 run on 120V.

So the real question is not "where is the cheap outdoor sauna". It is "is my budget buying a sauna, or is it buying a backyard structure that happens to contain one". Those are different purchases and it is worth knowing which one you are making before you compare prices. If you would rather have a person sort that in one pass than read the rest of this, our sauna buying advisors do exactly that.

Here is the whole catalog, split the only way that matters for this question. These are our listed prices, live on the site today.

• Indoor: 105 models. Floor $1,399, midpoint $3,299, ceiling $9,999. 30 under $2,500, 46 under $3,000, 80 under $5,000.
• Outdoor: 38 models. Floor $4,999, midpoint $7,999, ceiling $18,999. 1 under $5,000, 3 under $6,000, 13 under $7,000.

The midpoints are the number to sit with. The typical outdoor sauna on this site costs about two and a half times the typical indoor one. If you priced an indoor cabin, liked the number, and then switched your search to outdoor expecting a few hundred dollars of difference, that is the jump you just walked into, and it catches almost everybody.

The 38 outdoor models split 24 cabins and 14 barrels. The barrel is the shape most people picture, and it is not the cheap option by default. Our least expensive outdoor sauna happens to be a barrel, but so is one of our most expensive.

Three things change when a sauna moves outside, and each of them costs money independently.

1. The heat source changes. This is the big one and it is invisible in a price comparison. An indoor infrared cabin heats you with carbon or ceramic panels drawing about 1,700 watts, which is why it runs on a normal outlet and why it can be built cheaply. A traditional outdoor sauna heats the room with an electric stove and rocks, and stoves are expensive hardware. The stand-alone sauna heaters we sell start at $2,638. Before a single board of cedar is cut, an outdoor traditional sauna is carrying a component that costs more than our entire cheapest indoor cabin.

2. The shell has to survive weather. Indoor cabins are overwhelmingly Canadian Hemlock, a fine interior wood with no reason to be rot resistant. Outdoor units move to cedar and thermally modified species: our outdoor range publishes woods like Pacific Cedar, Canadian Red Cedar interior with an all weather exterior, and Thermo-Aspen. That is more material, denser material, and a finish schedule that indoor never needs.

3. The electrical service changes. Thirty two of the thirty eight outdoor models specify 240V. That is a dedicated circuit run out to the yard, which is an electrician, a permit in most places, and a trench or conduit. It is real money and it is not on the product page because it is not our line item, it is your contractor's. Our guide to who installs a home sauna walks through how that job is scoped.

None of those three are optional and none of them are margin. That is why the floor sits where it sits.

The one outdoor sauna we list under $5,000 is the Golden Designs "St. Moritz" 2-Person Barrel Traditional Steam Sauna, model GDI-B002-01, at $4,999. Its published spec sheet reads:

• Capacity: 2 Person
• Wood: Pacific Cedar
• Heater: 4.5kW Harvia Electric
• Max Temperature: 195°F
• Door: Tempered Glass
• Electrical: 240V dedicated circuit
• Warranty: 5 Year Limited

That is a complete traditional sauna with the stove included, which is worth saying out loud because it is not universal. 22 of our 38 outdoor models publish a Heater spec, and one of them reads "Sold separately, not included with kit" in plain language on the page. On that model the listed price is the shell. Read the Heater line before you compare two outdoor kits, because one of them may be quoting you a building and the other a building plus a stove.

Step up one rung and you are at $5,999, where both the 4-person Arosa barrel and the 3-person Arlberg cabin sit. If two people fit your use and you are choosing purely on cost, the St. Moritz is the floor of the category and there is nothing under it to find.

A budget under $3,000 is not a small budget in this category. It is an indoor budget, and indoors it buys well: 46 of our models are under $3,000 and 30 are under $2,500. Every one of those thirty plugs into a standard 120V outlet, which means no electrician, no permit, no trench.

The usual objection is that there is no room inside. That is worth testing before you accept it, because these are smaller than people assume and they do not need a dedicated room. The Dynamic Barcelona at $1,899 is 300 lbs shipped, clasps together with no tools, and runs on 120V/15A. A garage corner, a finished basement, or a spare bedroom wall all work. Our guide on whether a home sauna fits in your room covers the clearances honestly, and what you actually get under $2,500 lays out the full shelf.

If it genuinely has to be outside, then the useful move is to change the timeline rather than the product. Financing is available through Shop Pay Installments, subject to approval. Waiting a season and buying the St. Moritz is a better outcome than buying an indoor cabin you intended to put in the weather, which voids the warranty on every model we sell and is not something we will help you do.

If you want a person to sanity check the room, the circuit, or the freight before you commit, our US-based buying advisors do this every day and there is no pressure attached to it. Start at the sauna concierge or browse the outdoor range and the infrared range side by side.

Is there any outdoor sauna under $3,000?

Not in our catalog, and we would rather say so than send you looking. Of the 38 outdoor saunas we list, the least expensive is $4,999 and only that one model sits under $5,000. Anything advertised well below that is usually either an indoor cabin being marketed for outdoor use, or a shell sold without its heater.

Why are outdoor saunas so much more expensive than infrared ones?

Because they are a different machine. Every one of our 38 outdoor saunas is traditional steam or hybrid, heated by an electric stove and rocks, and stand-alone stoves in our catalog start at $2,638. Infrared cabins heat you directly with carbon panels instead, which is far cheaper to build, and 88 of our 105 indoor models use that method.

Can I put an indoor infrared sauna outside to save money?

No. Indoor cabins are built in Canadian Hemlock and are not rated for weather exposure, and putting one outdoors voids the manufacturer warranty on every model we carry. If the sauna has to live outside, it needs to be an outdoor rated unit.

Do I need an electrician for an outdoor sauna?

Almost certainly. 32 of our 38 outdoor models specify a 240V circuit, one specifies 120V, and five publish no electrical spec. By contrast 68 of our 105 indoor models run on a standard 120V household outlet, and all 30 of the models under $2,500 do.

Is a barrel sauna cheaper than a cabin?

Not as a rule. Our outdoor range is 24 cabins and 14 barrels, and the shape does not set the price. Our least expensive outdoor sauna is a barrel and so is one of the most expensive. Capacity, wood, and heater size move the number far more than the silhouette does.
