The Home Sauna Buyer's Guide

The two main styles, explained simply

Traditional sauna (also called Finnish sauna). Picture a wooden room with a heater in the corner. On top of that heater sit stones. The heater warms the stones and the stones warm the air, so the whole room gets hot, roughly 150 to 195 degrees Fahrenheit. That is hot enough that you start sweating within about 5 to 10 minutes of sitting down.

You can ladle a little water onto the hot stones to make a quick burst of steam and a wave of heat. In Finnish tradition this is called "loyly" (say it "LOO-loo"). It is the splash-and-sizzle moment people picture when they imagine a sauna.

This is the oldest style. People in Northern Europe have used saunas like this for more than 2,000 years.

• How hot: about 150 to 195 F. Think oven-warm air all around you.
• How much electricity it pulls: roughly 6 to 9 kilowatts (kW) for a cabin that seats 2 to 4 people. A kilowatt is just a measure of how much electricity a device draws. For comparison, a small space heater is about 1.5 kW, so a traditional sauna heater is like running four to six space heaters at once. That is why these almost always need special wiring (more in Chapter 6).
• Warm-up time: about 30 to 45 minutes before it is ready. You turn it on, then come back.

Infrared sauna. Instead of heating the whole room, an infrared sauna uses panels that give off infrared heat, which your skin absorbs directly. Here is the useful mental picture: on a cool day you can stand in a patch of sunlight coming through a window and feel warm, even though the air around you is not hot. Infrared works the same way. It warms you, not so much the air.

Because of that, the air in an infrared sauna stays much cooler, about 110 to 140 F. It feels milder and easier to sit in. But do not mistake milder for weaker: people still sweat about as much as in a traditional sauna. It just feels gentler getting there.

• How hot the air is: about 110 to 140 F. Warm, not oven-hot.
• How much electricity it pulls: roughly 1.5 to 2.5 kW for a 1 to 3 person unit. That is far less than a traditional sauna, in the range of one to two space heaters, which is why many infrared saunas can run on a normal household outlet.
• Warm-up time: about 10 to 15 minutes, quicker than traditional.

A note on infrared "sub-bands" (and a myth to ignore)

You will see infrared saunas advertised with terms like near, mid, and far infrared, or "full spectrum." Here is what that actually means, kept simple.

Infrared is a range of invisible heat energy. Scientists split that range into bands by wavelength, measured in micrometers (a micrometer is one millionth of a meter, far too small to see). Different sources define the bands slightly differently, and this matters because sauna marketing often uses cutoffs that do not match the official science.

The two recognized standards are:

Many sauna sellers instead use a looser "near / mid / far" split of their own (often around 0.76, 1.5, and 5.6 micrometers). Those numbers are an informal industry convention. They are not from ISO or CIE. So a panel labeled "far infrared" by a vendor may not line up with the official far-infrared band at all.

What is fair to say: near infrared and red light have the largest body of published research (for things like skin and wound healing). Far infrared is the most common type used in cabins. "Full spectrum" means the sauna produces all three bands; it costs more and needs better controls. None of this means one band gives you a specific medical result. More on that honest framing in Chapter 2.

Hybrid sauna. A hybrid puts both technologies in one cabin: infrared panels plus a traditional stone heater. You can use gentle infrared on some days and full traditional heat on others. This is the priciest option and pulls the most electricity, but it solves a real problem: two people under one roof who want completely different experiences.

Steam room (not a sauna, just so you know the difference). People sometimes confuse the two. A steam room is a sealed, tiled enclosure filled with 100 percent humidity from a separate steam generator, running cooler at about 110 to 120 F. It is wet, not dry, and is a different appliance entirely. This guide does not cover steam rooms.

At a glance

So which should you pick?

Two different bodies of research

When people ask "is a sauna good for me," they are really drawing on two separate sets of studies.

The larger, older research is about traditional Finnish saunas. The most cited work comes from a long-running study in Eastern Finland known as the KIHD cohort. Researchers followed 2,315 middle-aged men (ages 42 to 60) for a median of about 20.7 years, tracking how often they used the sauna and what happened to their health over time.

The headline finding: men who used the sauna most often, 4 to 7 times a week, had notably lower rates of heart-related death and death from any cause, compared with men who went just once a week. In that most-frequent group, the risk of sudden cardiac death was about 63 percent lower and fatal cardiovascular disease about 50 percent lower than in the once-a-week group.

Two honest clarifications matter here:

• The typical sauna session in the study averaged about 15 minutes (the full range ran from a couple of minutes up to 90). You may see "19 minutes" quoted elsewhere; that is not the average session, it is the cutoff for the longest-session group, which showed the strongest association. The sauna heat in the study was at least about 174 F.
• This is an observation, not proof of cause. The researchers watched what happened; they did not run a controlled experiment. Something else about frequent sauna users could explain part of the effect. A commentary published alongside the 2015 study specifically cautioned that the link may not be causal. The finding has since been repeated in other groups, including a 2018 study that extended it to women, which strengthens the pattern. But "linked to" is not the same as "will do this for you."

The smaller, newer research is about infrared saunas. Studies here have looked at things like blood pressure, chronic fatigue, fibromyalgia pain, and skin. The results are mixed but generally lean positive. This body of work is smaller and of more varied quality than the Finnish sauna research, so it supports cautious optimism, not firm promises.

Why heat might help at all

Both styles share a plausible mechanism, and it is worth understanding because it explains why the type of sauna matters less than simply using one.

When you sit in heat, your body has to work to cope with it. Your heart rate rises and your circulation ramps up, in a way researchers compare to moderate aerobic exercise. This mild, controlled stress triggers a recovery response in the body, including proteins that help protect and repair cells (called heat shock proteins), improved blood-vessel function, and effects on inflammation and the nervous system. This framing is mainstream and comes from the same researchers behind the Finnish studies.

The honest bottom line

A note on health and safety. This guide is educational and is not medical advice. Sauna heat raises your heart rate and can affect blood pressure. If you have a cardiovascular condition, are pregnant, or take prescription medications, talk with your physician before you begin. Start with shorter, cooler sessions and listen to your body.

What EMF even is

EMF stands for electromagnetic field. Any device that uses electricity, your fridge, your hair dryer, your laptop, gives off a low-frequency version of this. The specific kind that comes from ordinary household power is called extremely low frequency, or ELF, and it is measured in units called milligauss (mG). You do not need to memorize any of that. You just need to know it exists and how to think about it.

The reason it comes up with saunas is that infrared saunas have heating panels close to where you sit, and some buyers want reassurance those panels are low-emission.

The distance rule (the one thing that matters most)

Here is the single most useful fact about EMF: it fades very quickly with distance. Think of a campfire. Standing right next to it, the heat is strong. Take two steps back and it is much gentler. EMF behaves like that, only it fades even faster.

So the number that matters is not the reading pressed against the panel. It is the reading where your body actually sits, a few inches to a foot or more away. As an illustration, a panel reading 5 mG at its surface can read under 1 mG just 6 inches away, and under 0.1 mG at 18 inches. (Those are example figures, not a fixed spec; the exact drop-off depends on the panel.) The takeaway is simple: a few inches of distance cuts your exposure dramatically.

The standards, told straight

You will see sellers cite various "standards." Here is what they actually are, so you are not misled.

• The ICNIRP guideline: about 2,000 mG. ICNIRP is an independent scientific commission whose safety reference levels many countries adopt. Its 2010 guideline for everyday public exposure to household-frequency magnetic fields is 200 microtesla, which works out to about 2,000 mG. Note this is a whole-body exposure reference, not a limit for a single device or seat.

• The "Swedish" 2 to 3 mG figure: a monitor-era convention, not a building code. You will often see a claim that a "Swedish Building Standard" recommends staying under 3 mG. That is a misattribution. There is no such building standard. The real number traces back to Sweden's TCO and MPR certifications for computer monitors from decades ago, where the limit was about 2 mG measured 30 centimeters from a display. It is a voluntary equipment-emission convention, often rounded to 3 mG in the sauna trade. It is a reasonable low-emission target to ask a seller to meet, but it is not a regulatory or building requirement.

• In the United States, there is no federal EMF limit at all. The EPA states plainly there are no federal standards limiting these power-frequency fields. OSHA has no such exposure standard, and the FDA sets no sauna EMF limit. This is precisely why sellers cite ICNIRP or the old Swedish monitor conventions: there is no US rule to point to.

How to read the marketing labels

• "Low EMF" usually means roughly under 3 mG at the panel surface. This is the most common claim.
• "Ultra-low" or "near-zero EMF" usually means around 1 mG or below, achieved with special internal wiring that cancels out the fields.
• No EMF number published? Assume it is above 3 mG and ask.

Why this is its own decision

Indoor and outdoor saunas look similar but are built very differently. Getting this wrong is expensive, so it deserves its own chapter.

Indoor saunas are built for a dry, protected room. Typically they have a single-wall cabin of about one inch tongue-and-groove cedar or hemlock, no weather sealing, and they plug into a 120-volt or 240-volt outlet. They are not built to survive rain, snow, or outdoor humidity.

Outdoor saunas (often the classic barrel shape) are built tougher: thicker walls of about 1.5 to 2 inches, sealed weather-resistant finishes, a shingled or metal roof, and outdoor-rated fasteners that will not rust. They need a level, load-bearing foundation and their own weatherproof electrical run.

The mistake that costs people their warranty

First, a word about how saunas are sized

Saunas are named by how many people fit on the benches inside, not by how much floor they take up. A "2-person" sauna is not two feet wide. It is the bench space that seats two.

So the label tells you the inside. What you actually have to fit in your home is the outside. Always plan around the exterior dimensions plus a little breathing room, not the person count.

Rough outside sizes to picture it:

• A "2-person" infrared cabin is about 47 to 51 inches wide on the outside. Think a bit wider than a standard interior door lying flat.
• A "3-person" traditional cabin runs about 60 to 75 inches per side. Think a small closet or a large shower footprint.

The clearances (the empty space it needs around it)

A sauna gets warm on the outside too, and it needs airflow so the wood and electronics stay healthy. So you leave a small gap around it. "Clearance" just means empty space you keep clear.

Here is the full list. Keep this handy when you measure your room:

• 2 inches of air gap on all sides. The cabin should not be shoved tight against a wall. Two inches lets air move and heat escape.
• 6 inches in front of the door. Room to open the door and step out comfortably.
• 12 inches of space above the cabin. Assembled cabins stand about 75 to 80 inches tall. In a room with a standard 8-foot (96-inch) ceiling, that leaves you the headroom you need. Measure your ceiling first.
• 24 inches around the whole outside for outdoor barrel saunas. The extra room lets snow and rain shed off and keeps the wood from sitting against anything wet.

Will your floor hold it?

Yes, almost certainly, if it sits on the ground floor.

A sauna loaded with two adults inside weighs somewhere around 600 to 1,400 pounds total. That sounds like a lot, but it is spread across the floor, and a normal ground-level floor handles it without a thought. It is comparable to a few people standing together, or a full bathtub.

Two situations deserve a second look:

• Upstairs or on a second story. Building codes assume a typical home floor supports about 40 pounds per square foot of "live load" (live load means people and movable things, not the house itself). A ground floor on a slab is never a worry. A second-story installation is usually fine too, but it is worth a quick check with a contractor if the sauna is large.
• Traditional heaters add stones. The rocks piled on a traditional heater add roughly 60 to 100 pounds on their own. Still not a problem on a normal floor, just something to know.

If it goes outside: the foundation

An outdoor sauna cannot sit on grass, dirt, or loose gravel. The ground shifts and stays damp, and within a season or two the cabin racks out of square, doors stop closing, and the manufacturer will decline a warranty claim because the base was never right.

Any one of these three is a proper base:

• A poured concrete pad, about 4 inches thick, reinforced, over a gravel bed.
• A paver patio set on compacted gravel with edge restraint (the border that keeps the pavers from spreading).
• A pressure-treated wood deck rated to carry the sauna's weight and footprint.

This is the chapter that catches people off guard, so read it even if you skip others. The good news: once you know your model's power needs and take a quick look at your electrical panel, there are no more surprises.

Volts, amps, kilowatts, in plain words

You do not need to be an electrician. You need three ideas.

• Volts are the "pressure" of the electricity. Regular household outlets are 120 volts. Big appliances like an electric dryer or oven use 240 volts, double the pressure.
• Amps are the "flow rate," how much electricity moves at once. A circuit is rated for a maximum amps, protected by a breaker.
• Kilowatts (kW) are simply how much power the sauna pulls while running. Think of it like the difference between a desk lamp and a space heater. A lamp sips power; a space heater gulps it. A small infrared sauna is closer to the lamp end; a big traditional heater is firmly at the space-heater end.

That is the whole vocabulary. Now the two paths.

Path 1: The plug-and-play sauna (120 volts)

Most 1-person and many 2-person infrared saunas draw under 1.8 kW. They run on an ordinary 120-volt household outlet, the same kind your toaster uses. If you already have a dedicated outlet where the sauna will go, you plug it in. No electrician. This is the lowest-friction, lowest-cost way into sauna ownership.

Path 2: The hardwired sauna (240 volts)

Bigger saunas need real power. This includes:

• Larger infrared cabins (roughly 3 to 4 person).
• All traditional heaters above 4.5 kW.
• All hybrids.

These run on 240 volts, the same class of circuit as your electric range or dryer. That means:

• A 30-amp or 40-amp double-pole breaker (the wide, two-slot kind).
• A new run of heavy copper wire, 10-gauge or 8-gauge, from your electrical panel to the sauna.
• Either a hardwired connection or a dedicated 240-volt outlet.

A licensed electrician is nearly always required. Expect roughly $400 to $1,500 for the job. Where you land in that range depends on how far the sauna is from your panel, how long the wire run is, and local labor rates.

The one that ambushes people: panel capacity

Your electrical panel is the gray box with all the breakers. It has a limited total capacity, measured in amps.

• A 200-amp panel (common in newer homes) usually has plenty of headroom to add a sauna circuit. You are fine.
• A 100-amp panel (common in older homes) may already be close to full. Adding a 30-amp sauna circuit can push it over. Your electrician runs a quick "load calculation" (adding up what your home already draws) to check. Sometimes the answer is that you need a panel upgrade.

A panel upgrade is a separate, larger job, typically $1,200 to $2,500 or more, and higher in some regions. It is not included in that $400 to $1,500 wiring estimate. It is the single biggest and most surprising cost a sauna buyer can hit.

Your buyer checklist (bring this to the seller and to your electrician)

Copy these down. Getting written answers to all five removes every electrical surprise:

• The model's kW and voltage. Exactly how much power, and 120V or 240V.
• The required circuit amperage. 15, 20, 30, or 40 amp.
• Cord or hardwire. Does it plug in, or does it wire directly?
• Distance from your panel to the sauna's spot. Longer runs cost more.
• A written estimate from a licensed electrician, made against the install manual. Give the electrician the manufacturer's electrical page so the quote is real, not a guess.

This chapter is short, but it saves the most heartache per word. Ventilation problems do not show up on day one. They show up two or three years later, and by then they are expensive.

Why this matters

When a sauna runs, it warms the air and adds moisture, and some of that escapes into the room it sits in. Infrared saunas release less than traditional ones, but neither is a sealed box. So the room around the sauna matters as much as the sauna itself.

If that room can breathe, the moisture leaves and nothing happens. If that room is sealed tight, the moisture has nowhere to go. Over years, humidity can build to the point where untreated drywall or wood framing starts to grow mold. That is the quiet failure. It is completely preventable.

Indoor: give the room a way to breathe

The ideal indoor spot for a sauna has one of these already:

• A bathroom-style exhaust fan.
• A window you can open.
• A passive vent to the outside.

The worst spot is a sealed basement room with none of the above. That is exactly where moisture has nowhere to go.

The sauna's own vents

Separate from the room, the cabin itself should have venting so air circulates inside it. Look for at least two vents:

• A low intake vent, near the heater or floor, to draw fresh air in.
• A high exhaust vent, up top, to let used air out.

Both should be adjustable so you can control the airflow. A cabin with no venting heats poorly and traps stale air.

Outdoor: keep the door away from the weather

Outdoor saunas breathe through their built-in vents and natural air exchange, so the room-moisture problem does not apply. Instead, the concern is weather. Position the door so it is clear of the prevailing wind, out of the path of drifting snow, and away from direct rain.

A simple maintenance rhythm

None of this is demanding. A light routine keeps a sauna healthy for decades:

• After each session: wipe the benches dry.
• Weekly: prop the door open for about an hour after the last session so the interior dries fully.
• Monthly: vacuum the floor and give the heating elements a quick look.
• Yearly: if the manufacturer recommends it, a light sanding with 220-grit paper and a coat of food-safe paraffin oil keeps the wood fresh.

A sauna lives in heat and moisture for decades. What it is made of decides whether it ages gracefully or falls apart. Here is how to read the materials.

The woods, compared

A plain-language note on "low thermal conductivity," since it is the one cedar term worth understanding. It means the wood does not transfer heat quickly, so even in a hot sauna the cedar bench and walls stay comfortable to touch. That is why you can lean back against a cedar wall at 180 degrees and not flinch.

The one hard rule: no engineered wood

The glass

The door is often glass, and glass in a sauna has to be the right kind.

• Tempered safety glass, always. Tempered glass is heat-treated so that if it ever breaks, it crumbles into small blunt pieces instead of dangerous shards. This is non-negotiable near heat and moisture.
• Thickness: at least 6 mm. For a full-glass door, 8 mm is preferable and is the standard most quality makers ship.
• Handles: look for a full-frame metal handle. Wood handles tend to fail over time as moisture works into them.
• Tinting is purely cosmetic. It does not affect safety or performance.

The hardware and, for outdoor saunas, the roof

Small parts matter in a hot, damp box.

• Fasteners: any screw or fastener in a wet-contact spot should be stainless steel. Aluminum hinges are acceptable but inferior. Avoid bare steel inside, because it rusts.
• Outdoor roofing: asphalt shingles last about 15 to 20 years. Cedar shingles need resealing every 3 to 5 years. On barrel saunas, the metal bands should be powder-coated or stainless, because plain galvanized bands rust at the vapor edge within about 5 years.

A spec sheet (short for "specifications") is just the list of hard facts about a specific sauna model: how big it is, what it is made of, how much power it needs, how long it is covered. Marketing pages give you adjectives. The spec sheet gives you numbers. You want the numbers.

Here is the thing to hold onto: you are allowed to ask for this in writing before you buy. A serious dealer expects the question and answers it fast. If the answer is vague ("premium wood," "high-quality heater") or slow, that is information too.

Below is every line worth checking, in plain language, with what it means for you.

What to ask for, and why it matters

Think of a home sauna like a car. The body, the engine, and the electronics are different systems with different lifespans, and a smart warranty covers them separately. A sauna is the same. Read the warranty as three coverages, not one.

The three parts, and how long each is usually covered

Here is the part most guides get wrong, so pay attention: coverage is not the same from brand to brand, and some brands cover the wood for far less time than the heater.

For example, Golden Designs Inc. (the maker behind the Dynamic and Maxxus lines, which is what PureHeat carries) covers the heater and electronics for 5 years on residential units, but the wood structure for only 1 year. Some premium cedar-cabin brands do the reverse and cover the cabin for 5 to 7 years or more. Neither approach is "wrong." The point is that you cannot assume. You have to read each part separately.

What quietly voids a warranty

Warranties come with conditions. Break one and the manufacturer owes you nothing. The common ones:

• Putting an indoor sauna outdoors. The most frequent and most expensive mistake. Covered in Chapter 4.
• Using a residential sauna commercially (in a gym, rental, or spa).
• Third-party modifications (you or a handyman altering the unit).
• Assembly errors during your own build.
• Improper electrical work. This is the single most common reason a claim is denied. If the heater fails in the first year, many makers ask to see your licensed electrician's paperwork. No paperwork, no coverage. Keep that estimate and invoice.

Some warranties are transferable, meaning they carry over if you sell the sauna, which adds resale value. Many are not. For Golden Designs units specifically, coverage is tied to the original buyer and the original install location and is not transferable, so do not count on passing it to a future owner.

The one test that tells you the most

Before you buy, call the manufacturer's warranty phone number. Not the seller's, the manufacturer's. Ask a plain question about coverage. If a real person answers and can explain the terms clearly, that is the single best predictor that you will be taken care of if something goes wrong years from now. A warranty is only as good as the company standing behind it, and a five-minute phone call tells you whether that company is reachable.

You will run into three kinds of sellers. Knowing which is which protects the biggest purchase in this guide.

The three seller types

"Gray market" sounds shady but is often subtle. The sauna may be genuine. The price may be a touch lower. What you are quietly giving up is the manufacturer's backing. If the heater fails, the maker can simply say the unit was not sold through an approved channel, and you are on your own for the repair. That saved amount at checkout can vanish the first time anything goes wrong.

Becoming an authorized dealer is not casual. Manufacturers require a business registration, a resale certificate, a tax ID, banking details, and a formal review before granting authorization. That barrier is exactly why authorized status is worth verifying: it means the maker vetted the seller and agreed to stand behind the sale.

How to verify a dealer in five minutes

1. Ask the seller for written confirmation that they are an authorized dealer for that specific brand.
2. Call or email the manufacturer directly and ask them to confirm it.
3. If both line up, you are protected. If the seller dodges or the maker has never heard of them, walk away.

This one call is the most consequential thing you can do before buying. It costs nothing and it is the difference between a warranty that is real and one that is decorative.

Where PureHeat fits

PureHeat is an approved, authorized dealer for Golden Designs Inc., including the Dynamic and Maxxus lines. That means every sauna is fulfilled factory-direct from authorized inventory, with a valid manufacturer warranty (5-year residential coverage on the heater and electronics, 1-year on the wood structure), and no gray-market sourcing. You can verify PureHeat's authorized status with the manufacturer directly, and you are encouraged to. That is exactly the call this chapter recommends you make with any seller.

The most common buyer regret is not the sauna itself. It is a cost that showed up after checkout. So here is the honest, all-in picture, laid out plainly.

The true total cost

How free curbside freight actually works

"Free curbside freight" has a specific meaning, so here is exactly what to expect on delivery day.

• A large freight truck (up to 53 feet) brings your sauna to the end of your driveway. That is what "curbside" means: to the curb or driveway, not inside, not up steps, not through a door.
• Most saunas ship as a flat-pack kit, meaning several manageable boxes rather than one giant crate. Two adults can typically move the boxes.
• The heaviest single box is the real test, not the total weight. Check the "largest single-piece weight" on the spec sheet (Chapter 9) so you know what you are lifting.
• Be home to sign for it and inspect the boxes before the driver leaves. Note any visible damage on the delivery paperwork.

Delivery generally takes 10 to 20 business days. Alaska, Hawaii, and Canada are quoted separately.

The assembly reality

Most home saunas are designed for you to build, and it is more approachable than it sounds.

• Indoor cabin: two adults, roughly 2 to 6 hours.
• Outdoor barrel: two adults, roughly 4 to 10 hours.
• Tools: a cordless drill, a level, and a rubber mallet. That is essentially it.
• Prefer not to build it yourself? A contractor typically charges about $300 to $800 for assembly. Again, an estimate.

What it costs to run

This is where many buyers are pleasantly surprised. Remember, kW is just how much electricity the heater pulls, and you only pay for the time it runs.

Using a US residential electricity rate of about 17.5 cents per kWh (the national average as of mid-2026, per the U.S. Energy Information Administration), for someone using the sauna 4 times a week, about 45 minutes each session:

Two honest notes that make these figures more accurate, not less:

• These are conservative, upper-bound estimates. They assume the heater draws full power the entire session. In reality, once a traditional sauna reaches temperature, the heater cycles on and off with its thermostat, like a home furnace, so your real bill is often lower than the figure above.
• Infrared is dramatically cheaper to run than traditional, roughly a third to a quarter of the cost for the same usage, because it uses far less power and warms up faster. If low monthly cost matters to you, that gap is real.

The information in this part is general buying guidance, not legal, financial, or medical advice. Warranty terms, electrical requirements, and local codes vary. Confirm specifics with the manufacturer, a licensed electrician, and your local authorities before you buy.

Think of these five categories like aisles in a store. You do not shop the whole store. You walk to the one aisle that matches what you want, and there are only a handful of options in that aisle. That is the point of a curated collection: fewer, vetted choices instead of an endless catalog you have to police yourself.

Here is each aisle in plain terms.

The five categories at a glance

Let me walk through each one.

1. Infrared

The short version: The easy default. Milder air, direct body warmth, and many models plug into a regular outlet. If you are not sure where to start, start here.

Infrared saunas warm you the way the sun warms your skin on a cool day: the air around you stays fairly mild (roughly 110 to 140 F), but you still sweat because the heat is landing on you directly. Warm-up is short, usually about 10 to 15 minutes. Most one and two-person infrared units draw under 1.8 kW, which is a small enough electrical pull that many run on a standard 120V household outlet, the same kind your toaster uses. That means often no electrician and the lowest barrier to using it every day.

PureHeat's infrared models are chosen for low or near-zero EMF (the low-level electromagnetic field every electrical appliance gives off; see Part I if that term is new). This is the simplest, lowest-cost way into sauna ownership.

2. Full-Spectrum

The short version: Infrared, but with all three light bands included, notably the near-infrared / red-light range that has the most published research behind it. Costs more and usually needs a 240V circuit.

"Full-spectrum" means the sauna emits all three infrared sub-bands: far, mid, and near. Near-infrared (which overlaps with red-light therapy) is the band with the largest body of peer-reviewed research, mostly around skin and wound healing. Important and honest: more research on a band does not mean a specific model will produce a specific medical result for you. It means the science is better studied there, not that any one product is proven to treat a condition.

Full-spectrum units cost more than plain infrared and generally need a 240V circuit (the larger kind, like an electric dryer uses), which usually means hiring a licensed electrician.

3. Traditional Indoor

The short version: The original Finnish sauna. Rocks, high heat, and steam you make yourself by pouring water on the stones. Needs a 240V circuit.

A traditional sauna heats the whole room like an oven (typically 150 to 195 F), and you control humidity by ladling water onto hot stones, a practice called loyly. You feel heat within a few minutes. These run on 240V and warm up in roughly 30 to 45 minutes.

This is the category for people who love intense, enveloping heat and the ritual of steam. It asks more of your home electrically, but for many people the payoff is the "real sauna" experience.

4. Outdoor and PureTech Hybrid

The short version: Two things live here. Cabins actually built to survive weather, and "hybrid" cabins that combine traditional steam heat and full-spectrum infrared so two people with opposite tastes can each get what they want.

Outdoor saunas have thicker walls, sealed weather-resistant finishes, a real roof, and outdoor-rated fasteners. They need a level load-bearing foundation and a dedicated weatherproof electrical run. Hybrids put an infrared panel array and a traditional stone heater in the same cabin, so one person can do a mild infrared session and another can pour steam, without owning two saunas. Hybrids carry the highest price and the biggest electrical load of any category.

Note on warranty terms for outdoor and hybrid models specifically: confirm the coverage in writing before you buy, because outdoor and hybrid lines can carry different warranty terms than the standard indoor line. More on warranty below.

5. Cold Therapy

The short version: This is the odd one out. It is a cold plunge tub, not a heated sauna. It is here for people building a hot-and-cold recovery routine.

PureHeat's cold therapy option is a cedar cold plunge that drains by gravity and runs at ambient (room or outdoor) temperature without a chiller. Many people pair a sauna session with a cold plunge afterward. If that is your goal, this is the aisle.

Which category is right for me? A simple path

Follow the first line that matches you:

• You want the easiest possible start and to use it daily, on a normal outlet. Go to Infrared.
• You specifically want near-infrared / red-light features. Go to Full-Spectrum.
• You love high heat and real steam, and 240V power is available. Go to Traditional Indoor.
• It is going outside, or two people want very different experiences. Go to Outdoor and PureTech Hybrid.
• You mainly want cold plunging, alone or after heat. Go to Cold Therapy.

Two free tools do the narrowing for you

You do not have to figure out the exact model yourself. The site has two tools:

• The Find Your Sauna quiz asks a few questions about your space, power, and goals, then points you to matching models.
• The Will It Fit 3D tool and the ROI / cost calculator let you check that a specific sauna fits your room and see the long-term cost compared to spa or gym spending.

Every model in the collection has already been vetted for room footprint, electrical compatibility, heater technology, and long-term value. Pricing is pulled live on the site, so what you see is current.

Why "authorized dealer" is the part that matters

Earlier, the guide drew a line between authorized dealers and gray-market sellers. Here is where it applies. PureHeat is a fully approved authorized dealer for Golden Designs Inc. and its Dynamic and Maxxus lines (and Dynamic Cold Therapy). That means your sauna ships from the factory as authorized inventory, and your manufacturer warranty is valid, not the kind of coverage that quietly evaporates because the unit came through an unauthorized channel.

The warranty, stated honestly

You will see the phrase "full manufacturer warranty," and that is accurate, but here is exactly what it covers so there are no surprises later.

Golden Designs' residential limited warranty is:

So "5-year warranty" is true for the heater and electronics, which are the parts most likely to matter for a repair. The wood structure carries a shorter 1-year term. Commercial use (a gym, spa, or rental) is 1 year on everything. This guide would rather you know that up front than discover it during a claim.

The honest test from earlier still applies: before you buy anything, from anyone, call the maker's warranty line and see if a real person answers. That is the best signal of what support will feel like after the sale.

Delivery: what actually shows up, and how

Your sauna ships factory-direct with free curbside freight to your driveway. Plain-language version of what that means:

• A freight truck (up to a 53-foot trailer) brings your sauna to the end of your driveway.
• Most saunas arrive as a flat-pack kit: manageable boxes that two adults can move and assemble, not one giant crate you need a crane for.
• Typical transit is 10 to 20 business days. Alaska, Hawaii, and Canada are quoted separately.
• Be home to sign for it and inspect the boxes before the driver leaves.

Ordering terms, in plain words

• Checkout is standard secure Shopify: credit card, Shop Pay, Apple Pay, or Google Pay.
• Every sauna carries its manufacturer warranty.
• You can cancel for free any time before the manufacturer starts your shipment. Once the factory begins fulfilling your order, cancellation is no longer free, so if you are unsure, ask before that point.

Why a small collection instead of a giant catalog

PureHeat carries a curated set, not an endless list. That is a deliberate choice. Every model has been checked for footprint, electrical fit, heater quality, and long-term value, so the shortlist you see has already had the obvious mismatches removed. Fewer choices, each one vetted, is easier to shop than a thousand look-alike listings you have to vet yourself.
