How does delivery work?

Free freight to the contiguous 48. On every Finnmark sauna and the SoulCold plunge. Accessories travel by parcel and follow the store threshold, shown at checkout before you pay.

Freight, not parcel. Saunas ship palletized, as flat panels rather than a finished room. The carrier books a window, someone signs, and delivery is curbside rather than inside.

Plan for the weight. An FD-1 crate is about 349 pounds and the barrels are over 1,000. Two people, and somewhere flat and dry to stage it.

Measure the route before the truck comes. A sauna arrives as panels, so the narrowest doorway, stair turn or lift matters more than the finished footprint. Tell us first if a truck cannot reach your door.

If it arrives damaged. Note it on the paperwork before signing, photograph it, and tell us within 48 hours. If a pallet is punctured, crushed or structurally damaged, refuse it and call us while the driver is there.

Where we ship. The contiguous 48. Canada is a flat freight charge. Puerto Rico, Alaska and Hawaii are quoted case by case. No P.O. boxes.

Not included: the electrical work. Every Finnmark sauna wants a dedicated circuit of the rating on its page, and the cabins are a two person build. Professional setup and assembly is available.

Read the full Finnmark Shipping Policy

What does the warranty cover?

Lifetime on the Spectrum Plus elements. In home use, indoors and outdoors. That is the longest heater term on any brand we carry.

Ten years on the rest. The Spectrum Carbon heaters and the LED lighting run 10 years. The cabin and the controls run 10 years indoors, 5 outdoors. Remotes and the seat cushion are 1 year.

Not covered. Anything not fitted at the factory. The optional outdoor cover is warranted by material, 5 years on the roof and 10 on the side walls.

Residential only. Finnmark's terms are written for home use, so ask us to confirm cover in writing before you order for a gym, studio or rental.

Two conditions decide most claims. Assembled and placed as the manual requires, including 3 inches of clearance all round and a dedicated circuit. And damage found on delivery reported within 48 hours, with photographs, before assembly.

The Harvia stove and the plunge are separate. The stove inside a Trinity carries Harvia's warranty. The SoulCold has its own 1 year consumer term.

Who handles it. We file the claim for you. Call with your order number, the model, and the serial number from the plate under the bench. Ask and we will send you a free copy of the full warranty before you buy.

Read the full Finnmark Warranty Policy

What if I need to return it?

30 days from purchase. On a Finnmark sauna or the SoulCold plunge. We handle it, so you do not contact the manufacturer or the distributor yourself.

What a return costs. A restocking fee of up to 5% may apply on a change of mind, and we waive it whenever we are not charged ourselves. Consumables such as the SoulCold filter packs are not returnable once opened.

Who pays the return freight. You do on a change of mind, which on a palletized sauna is the real cost to weigh up. We pay the return freight when the cause is shipping damage or our error.

Original shipping. Not refunded on a change of mind return, and we never deduct the outbound freight from your refund.

Condition. New, unassembled and resalable in the original packaging with all parts. A sauna whose panels have been screwed together cannot go back.

Damaged on arrival. A different and faster process. Note it before signing, photograph it, and report within 48 hours before assembly. Refuse a punctured or crushed pallet and call us.

To start a return. Call or email with your order number. We issue the Return Authorization number, required before anything ships back, and send the address with it.

The short answer

The Finnmark FD-1 is a one person infrared sauna that runs on an ordinary household voltage

Finnmark Designs builds the FD-1 as a cabin of about 37 by 37.8 inches in Canadian cedar and heat treated aspen, with carbon panels on both side walls, a Spectrum Plus element behind you and a near infrared LED overhead. It takes the three pin outlet already on your wall, though that outlet has to be a circuit of its own. Three things decide it: the floor, the ceiling and the breaker.

The room

44 × 44 in

37 inches wide, 37.8 deep, 78.3 tall, plus the 3 inches of clearance Finnmark asks for on every side and above. Plan 44 inches square of floor and 82 of ceiling.

The fit

One person

Inside is 33.3 by 34.1 inches and 70.5 tall, on a bench 33.3 wide and 17.7 deep. One seat, upright.

The power

120 V, 15 A

1450 watts on a dedicated 15 amp circuit, through the ordinary NEMA 5-15 outlet. No 240 volt work, but the breaker must carry nothing else.

Fit

Inside the Finnmark FD-1: 33.3 by 34.1 inches, and 70.5 inches of headroom

One seat, and Finnmark publishes the numbers for it. Measure a chair you are comfortable in against the figures below before you decide.

Inside the cabin
Interior width 33.3 in
Interior depth 34.1 in
Interior height 70.5 in
Bench 33.3 in wide, 17.7 in deep, with an ergonomic backrest
Door opening 21.65 in wide, 67.88 in high, 8 mm tempered glass

Seventy and a half inches of interior height is floor panel to ceiling, not bench to ceiling. Finnmark publishes one seat for this model and we do not stretch that to two.

The cedar bench and its ergonomic backrest. The Spectrum Plus element sits on the back wall behind the backrest, with a carbon panel on each side wall.

Where the heat comes from

Finnmark's manual names each emitter and its part number in the replacement parts list, so the complement is knowable rather than inferred. The back wall carries a Spectrum Plus Incoloy element at 300 watts. The left and right walls each carry a carbon panel, also 300 watts. A further infrared panel is built into the bench skirt. Overhead sit the Spectrum LED ceiling lights, which give twelve colours and a near infrared setting.

Pairing carbon panels with Spectrum Plus elements is why Finnmark titles the FD-1 spec sheet a full spectrum sauna. The two Trinity models higher up the range run Spectrum Plus on every wall, with no carbon at all.

Before you order

Five checks before the Finnmark FD-1 ships

None of these is difficult. All of them are easier to answer with a tape measure than after a pallet arrives.

  • Floor, with the clearanceThe cabin is 37 by 37.8 inches and Finnmark asks for 3 inches on every side, which is 43 by 44, so plan 44 square
  • Ceiling, with the clearance78.3 inches tall plus 3 inches above it is 81.3, so plan on 82 inches, which is 6 feet 10. A standard 8 foot basement is fine; a finished basement with ducting below the joists may not be
  • The route to the roomIt arrives as flat panels, so measure the narrowest doorway or stair turn on the way, not the finished footprint
  • A free circuitDedicated 15 amp, 120 volt, NEMA 5-15. Dedicated means nothing else draws on it
  • A solid, dry, indoor floorFinnmark asks for a solid surface in a dry area. Adjustable feet take up floors that are not quite level
This is an indoor sauna, in the manufacturer's own words. The manual says the FD-1 "contains electronics and is intended for indoor use", and that placing it outside without a cover will void the warranty. Finnmark does sell a fitted FD-1 cover and describes it as limited weather protection rather than full protection. The manual also requires the cabin to stand free: it "should not be built into any structure" and is a self contained, freestanding unit, so it cannot be framed into an alcove or boxed in with joinery.

If a number is borderline, compare the cabin against the rest of the Finnmark saunas before you decide.

Construction

Three things about the Finnmark FD-1 you cannot change later

Everything else on a sauna is adjustable. These are set the day it is made.

The two timbers

Inside is Western Canadian cedar, which Finnmark specifies for its resistance to mould, bacteria and fungus. Outside is Thermal Plus aspen, which Finnmark describes as treated with heat and steam. The two woods do different jobs: the cedar is the surface you sit against, the treated aspen is the shell that faces the room.

The wall itself

The panels are double walled, with what Finnmark lists as non toxic wool insulation between the skins. Insulation is not something that can be added to a cabin afterwards.

The emitters

Finnmark warrants the Spectrum Plus elements for the life of the sauna and the carbon heaters for ten years. Those are the longest terms anywhere on the warranty sheet.

Finnmark's own layout for the FD-1: Spectrum Plus on the back wall, carbon left and right, and the Spectrum LED overhead.

Compare it against the other infrared saunas we carry, or narrow to the full spectrum saunas. If you are weighing infrared against a traditional stove, our infrared or traditional sauna guide covers the difference.

The decision that blocks the purchase

What the Finnmark FD-1 asks of your electrical panel

On most saunas this is the expensive conversation. On the FD-1 it is the smallest in the range, because there is no 240 volt work. There is still a circuit.

Electrical, from the FD-1 manual
Voltage and power 120 VAC, 1450 W
Circuit requirement Dedicated 15A circuit
Receptacle NEMA 5-15, the ordinary household three pin outlet
Code Install per the National Electrical Code, ANSI/NFPA 70. In Canada, per the applicable Canadian code

Dedicated is the condition. A NEMA 5-15 is the outlet already on your wall, which is why this model gets called plug and play, but the manual wants that outlet on a breaker with nothing else on it. Finnmark's troubleshooting page for a breaker tripping during use says to check the breaker amperage and to "ensure no other devices are on the same circuit".

If a spare 15 amp circuit already reaches the spot you want, you are done. If not, running one is a far shorter job than the 240 volt line an FD-3 or an FD-5 needs.

A licensed electrician sizes and installs the circuit, not us and not the manual. The figures above are what Finnmark publishes and what your electrician will ask for. Panel capacity, run length and local permit rules all change the job, and the manual requires the work to meet the National Electrical Code.

The wattage, and why the three published figures differ

Page 5 of the FD-1 manual reads "Power: 120V / 1450w / 15A", which is 12.1 amps, or 80.6 percent of a 15 amp breaker. The dealer file says 1.5 kilowatts and the 2023 spec sheet says 1750 watts; at 120 volts that last figure would draw 14.6 amps, 97 percent of the breaker, so we follow the manual.

Running cost

What a Finnmark FD-1 session costs to run

Worked at the manual's 1450 watts and the US average residential rate of 18.34 cents per kilowatt hour, from the EIA Electric Power Monthly, June 2026. Your own rate is on your bill.

One hour session

$0.27

1.45 kilowatts for one hour, at 18.34 cents. Less once the cabin is up to temperature and the heaters begin cycling.

A month

$3.46

Three sessions a week, an hour each, about 13 hours a month.

A year

$41

The same three a week, every week. Roughly 156 hours.

Every input is above, so redo it with your own rate: kilowatts times hours times cents.

Scope

Setup

Assembling the Finnmark FD-1

It arrives as panels and goes together without specialist tools.

The manual's tool list for this model is a screwdriver and a level. Panels lock to each other and are fixed with two screw lengths Finnmark supplies, longer ones for the back wall and shorter ones for the front. The heater cable connects from the bench support to a connector on the back wall, and the manual notes that the interior and exterior receptacles on the right panel are not used during assembly.

Two steps need a second person. The manual asks you to have someone hold the back panel upright while it is positioned so it cannot tip, and to lift the top panel with two people while feeding the wiring through the access holes. It also warns, in those words, not to lift or carry the front wall panel by the top left bar of the sauna. We do not publish an assembly time, because Finnmark does not state one.

Before the first session

Wipe the inside down with a damp cloth to clear any sawdust. Then run the cabin at its maximum temperature for an hour, two to four times, to burn off factory dust before anyone uses it. The serial number plate, which you will want if you ever make a warranty claim, sits underneath the bench.

Delivery day

What to check when your Finnmark FD-1 is delivered

It moves by freight and comes off the truck at the curb. Ten minutes of checking there is the difference between a replacement panel and an argument.

Before delivery

Have your second person booked for the day itself, not for the week after.

At the truck

Walk around the pallet before you sign. Photograph any crushed corner, tear or water mark, and write what you see on the delivery paperwork before you sign.

Before you build

Open the crate and check the glass door and each panel face while the packaging is still there, and tell us straight away if anything is marked. Our return policy sets out the window.

If a panel or the glass is visibly damaged, note it on the paperwork before the driver leaves and call us on (888) 500-5675 while they are still there. We would far rather sort it out at the curb than after the truck has gone.

The range

The Finnmark FD-1 against the rest of the Finnmark indoor rooms

Three infrared only cabins, then two that add a traditional stove. The jump that matters is from the FD-2 to the FD-3, because that is where a 240 volt circuit starts.

Pick the FD-1 for one person and the smallest electrical ask in the range. Step up to the FD-2 if a second seat matters: it is the only place in the range where capacity rises without the electrics changing. Go to the FD-3 once a 240 volt line is worth running. The two Trinity models are a different product rather than a bigger one, adding a Harvia stove and stones so you can raise steam, on two circuits instead of one.

The stove inside a Trinity is one we stock on its own: the Harvia Vega Compact 1900 on the FD-4 and the Harvia KIP45B on the FD-5.

Evidence

The Finnmark FD-1 low EMF reading, and what the certificates say

Two documents on this sauna are worth reading in full. Here is what each actually says.

The low EMF survey, in full

A third party laboratory in Tempe, Arizona measured Finnmark's Spectrum+ heaters in December 2019 under project PR108242, at three positions on each heater. With everything switched off, the room itself read 0.5304 milligauss. Running, the readings ran from 0.6881 milligauss up to a maximum of 1.1708 milligauss at the third position. So the heater added between 0.2 and 0.64 milligauss over what the room was already producing. The laboratory describes every result as magnitudes lower than the ICNIRP Occupational 2010 test limit.

The 1.1708 maximum is the laboratory's own headline figure, from position three; position one at 100 Hz read 0.7328. Three caveats: the limit is the occupational one rather than the general public one, the survey tested heaters rather than an assembled cabin, and pages four and six of the log name the customer as Influence Sauna rather than Finnmark Designs.

What the certificates actually say

The FD-1 is named on both Intertek certificates we hold, as ETL Listed to UL-875 and cETL to CAN/CSA-C22.2 No. 164. Those two certificates name the FD-1, FD-2, FD-3 and FD-4 and no others, which is why we do not call the FD-5, FD-6 or FD-7 listed. Separately, Finnmark identifies its Spectrum Plus elements as UL component recognised under file E65554, which covers sheathed heating elements as a component rather than a finished sauna. That record names the tradename BKR, not Finnmark and not Spectrum Plus. We do not describe any Finnmark cabin as a UL listed sauna, because that is not what that record says.

What we do not have

No owner reviews of our own yet, because this is a new listing for us, and no independent test of a finished FD-1 cabin as opposed to its heaters.

Buyer questions

Finnmark FD-1, questions buyers ask before ordering

Can the Finnmark FD-1 plug into a normal outlet?

Into a normal outlet type, yes: a NEMA 5-15 at 120 volts. What the manual asks on top of that is a dedicated 15 amp circuit, meaning the breaker feeding it has nothing else on it. If your corner is served by a circuit that also runs a freezer or a laundry, have an electrician add one before the sauna arrives. That is the whole electrical job on this model, and it is the smallest in the Finnmark range.

How hot does the Finnmark FD-1 get, and how long does it take to heat up?

Finnmark's spec sheet for this model claims 170 degrees in less than one hour on a 120 volt outlet. That is the manufacturer's figure and we quote it as theirs. Real heat-up depends on the starting temperature of the room, so a cabin in an unheated garage in winter will take longer than one in a spare bedroom. The Controller 2.0 touchscreen sets the temperature and the session length.

Can I put the Finnmark FD-1 outside or on a covered porch?

It is built as an indoor sauna. The manual says it contains electronics and is intended for indoor use, and that placing it outside without a cover will void the warranty. Finnmark's fitted cover is described as limited weather protection, not full protection. A basement, garage, spare bedroom or new extension suits it. For a covered porch, call us first and we will go through the specifics.

What is the difference between the carbon panels and the Spectrum Plus element?

Two different emitter technologies in the same cabin. The carbon panels on the side walls are flat and cover a wide area at a lower surface temperature. The Spectrum Plus Incoloy element on the back wall is the one Finnmark warrants for the life of the sauna, against ten years on carbon. Having both is what makes this a full spectrum cabin, where the Trinity models run Spectrum Plus on every wall with no carbon at all.

How much EMF does the Finnmark FD-1 produce?

Measured by a third party laboratory in December 2019 at three positions. An empty room read 0.5304 milligauss and the heater running read between 0.6881 and a maximum of 1.1708, so it added between 0.2 and 0.64 milligauss over the room itself. The full table, the position each reading came from and the three caveats that go with them are in the section above.

What is the warranty on the Finnmark FD-1?

Lifetime on the Spectrum Plus elements, ten years on the carbon heaters, the cabin, the controls and the LED lighting, one year on the remote, and nothing on parts not fitted at the factory. The full terms, including the residential use condition, are in the specification table above. Ask us and we will send you the warranty document free before you buy.

How is the Finnmark FD-1 delivered?

By freight, with no delivery charge to the lower 48, as flat panels on a pallet rather than an assembled room. The driver brings it to the curb, so plan a second pair of hands and somewhere flat and dry to stage it. Walk the pallet before you sign, photograph any damage and write it on the paperwork, because that note is what a freight claim rests on. Canada is a flat quote; Puerto Rico, Alaska and Hawaii are quoted case by case.

Am I buying from an authorized Finnmark dealer?

Yes. Recovery Room Direct is a factory authorized Finnmark Designs dealer, so your FD-1 carries the full factory warranty rather than a reseller term. It also means the specification here comes from the manufacturer's own documents rather than from copied listings. Finnmark sets a minimum advertised price and enforces it, so if you find an authorized dealer advertising below it, our price match covers it.

One last thing

Before you order the Finnmark FD-1: the ceiling and the breaker

Two measurements and one circuit decide this purchase. Tell us the room, the ceiling height and what else is on the breaker, and we will tell you whether the FD-1 fits or whether you want the FD-2 instead.
