Home Sauna Guide: Infrared vs Traditional (2026)

I've owned three saunas in the last four years — a $700 portable infrared blanket I still use for travel, a $4,500 Sun Home Solstice cabin in my garage, and a backyard barrel sauna I helped a friend build from a Finnleo kit. I've also rented enough Airbnbs with "saunas" that turned out to be a heat lamp in a closet to know what good sauna actually feels like.

This is the guide I wish I'd had when I started. It's not "10 best saunas on Amazon" listicle bait. It's a real buying framework — what the research actually says, what the meaningful differences between infrared and traditional are (and aren't), and what you should actually spend at each budget tier.

If you're trying to figure out whether to drop $300 on a sauna blanket, $4,500 on an infrared cabin, or $12,000 on a Finnish wood-burning setup in the backyard, this is for you.

Key Takeaways

• Infrared vs traditional: pick on lifestyle, not on health claims. The cardiovascular research is overwhelmingly on traditional Finnish saunas (80°C+, humid). Infrared has thinner evidence but real benefits, mostly via heat exposure and a relaxation response. If you want the maximum-evidence protocol, get traditional. If you want something you'll actually use four times a week without a 240V install, get infrared.
• The dose that moved mortality in the Finnish data: 4+ sessions per week, 19+ minutes per session, 80°C or hotter. Two sessions per week barely moved the needle. The frequency is the point.
• Budget tiers (real numbers): $300–800 for a portable blanket or tent, $1,500–3,500 for an entry barrel or mid-tier infrared cabin, $4,000–7,000 for premium infrared, $8,000–15,000+ for custom installs or premium outdoor traditional.
• The DIY/portable option competes harder than you'd think. A $1,500 infrared blanket plus a chest-freezer cold plunge gets you maybe 70% of the longevity benefit of a $10,000 sauna-and-plunge setup. The other 30% is real — but it's the ritual, the heat depth, and the contrast that costs you, not the cardiovascular adaptation.
• The 240V power requirement trips up more buyers than anything else. Most traditional cabin saunas above 4.5kW need a dedicated 240V circuit. Most infrared saunas under 1800W run on standard 110V. Check your electrical panel before you check your shopping cart.

What Sauna Therapy Actually Does

Sauna research is one of those areas where the popular media has gotten ahead of the data in some places and behind it in others. Let me clear up what's actually known.

The strongest evidence comes from a series of Finnish studies led by Jari Laukkanen at the University of Eastern Finland, drawing on the Kuopio Ischemic Heart Disease (KIHD) cohort — over 2,300 middle-aged men followed for two decades, with detailed sauna habits recorded throughout. Finland is the rare country where almost everyone uses a sauna, which makes it the only place on earth where you can run an epidemiological study on sauna with a meaningful dose-response curve.

Here's the headline finding from Laukkanen et al. (JAMA Internal Medicine, 2015): men who used the sauna 4–7 times per week had a 40% lower all-cause mortality and a 63% lower risk of sudden cardiac death than men who used the sauna once per week, over 20 years of follow-up. The relationship was dose-dependent — duration per session and temperature both mattered.

The mechanisms are reasonably well characterized:

• Acute cardiovascular load similar to moderate exercise. A 30-minute Finnish sauna session pushes heart rate to roughly 120–150 bpm and improves arterial compliance acutely. Over months, regular use lowers blood pressure and improves endothelial function.
• Heat-shock protein induction. HSP70 and HSP90 rise meaningfully after heat exposure. These chaperone proteins clear misfolded proteins and confer some cellular resilience.
• Plasma volume expansion. Repeated heat exposure increases plasma volume, which is why endurance athletes have used sauna as a heat-acclimation tool for decades.
• Catecholamine and norepinephrine release. Acute heat exposure roughly triples norepinephrine — part of why people feel sharper and more energized after.

The popular concept of "Søberg-style" sauna protocols is mostly Andrew Huberman's framing — he's drawn on the Laukkanen data and on Susanna Søberg's cold-exposure work to recommend 4+ sessions per week, 12–20 minutes each, at temperatures above 80°C, with cold exposure stacked on top. That's a reasonable distillation, and it's what I aim for myself.

What the research does not convincingly show:

• That infrared saunas produce the same cardiovascular adaptations as traditional. Some smaller studies are encouraging, but you should know that when somebody cites "sauna research" for an infrared product, they're almost always extrapolating from Finnish data on 80°C+ humid saunas.
• That you sweat out heavy metals or toxins in any clinically meaningful way. Sweat is mostly water and electrolytes. The "detox" claim is mostly marketing.
• That sauna meaningfully accelerates fat loss. It doesn't.

Real Benefits Backed by Research

Cardiovascular (the strongest evidence)

This is the unambiguous winner. Laukkanen and colleagues have published more than 30 papers on the KIHD cohort, and the pattern is clear: regular sauna use is associated with lower blood pressure, lower risk of hypertension, lower stroke risk, lower risk of fatal cardiovascular disease, and a reduced risk of dementia and Alzheimer's.

The dose-response is the part that matters and the part most people miss. From the 2015 paper:

The threshold for sessions per week is roughly where the curve bends. Two is good, four is much better.

All-Cause Mortality

Same paper, same cohort. Men in the highest sauna-frequency group (4–7×/week, 19+ min per session) had a 40% lower all-cause mortality over 20 years. This survives adjustment for cardiovascular risk factors, smoking, BMI, and exercise. It's one of the largest mortality signals in any consumer-accessible lifestyle intervention besides exercise itself.

Important caveats: this is observational data on Finnish men. We don't know if it translates fully to women, to non-Finns, or to people who aren't already in a culture that sauna is normalized in. But the biological plausibility is high, and the effect size is too large to ignore.

Heat-Shock Proteins

HSP70 and HSP90 rise after sauna sessions and are implicated in cellular resilience, protein-folding integrity, and possibly proteostasis-related longevity mechanisms. This is more biochemically suggestive than clinically proven, but it's the most plausible cellular mechanism for the mortality data.

Mood and Depression

A 2016 JAMA Psychiatry paper (Janssen et al.) showed that a single session of whole-body hyperthermia (essentially a high-dose infrared exposure designed to elevate core body temperature) produced a significant and sustained antidepressant effect lasting up to six weeks. This is one of the more encouraging early signals for infrared specifically. Regular sauna use is also associated with reduced risk of psychotic disorders and dementia in the KIHD data.

Sleep

Subjective sleep quality improvements are reported by basically everyone who saunas regularly, and they're partially supported by data: the post-sauna drop in core body temperature mimics the natural circadian temperature drop that initiates sleep. Best timing for sleep benefit: 1–3 hours before bed.

Infrared vs Traditional: The Real Comparison

This is the question I get asked the most. The honest answer is: they're different tools, and the choice is mostly about practicality, not health.

Heat Mechanism

Traditional (Finnish): Convective and radiant. Hot stones heat the air, you throw water (löyly) to spike humidity, and the heat reaches you through hot air and humid steam. Your skin temperature climbs because the ambient air is 80–100°C.

Infrared: Radiant only. Infrared emitters (carbon or ceramic) emit far-infrared (FIR) and sometimes near-infrared (NIR) wavelengths that penetrate skin and warm tissue directly. The air around you stays cooler — usually 50–65°C.

This is the core difference, and it shapes everything downstream. In a traditional sauna, you're being heated by the environment. In an infrared sauna, you're being heated more directly by the wavelengths hitting your body.

Temperature Ranges

• Traditional Finnish: 70–110°C (160–230°F), with 10–40% humidity depending on löyly use
• Infrared: 40–65°C (110–150°F), with very low humidity (whatever the room ambient is)

The temperature difference is why infrared sessions are typically 30–45 minutes and traditional are 15–25 minutes. You need longer at lower air temperatures to drive an equivalent core-temperature response.

Sweat Composition (Myth vs Reality)

You'll see infrared marketing claim that infrared sweat is "deeper" and contains more toxins. The most-cited paper for this (Sears et al., 2012) has been criticized for methodology — they were looking at sweat in people undergoing chelation, not normal individuals. In a normal healthy person, sweat is overwhelmingly water and electrolytes, with trace amounts of urea and metabolic byproducts. Heavy-metal excretion via sweat is real but clinically trivial compared to renal excretion.

If you want to feel like you're sweating, infrared and traditional both deliver. If you want to feel like you're "detoxing," eat more cruciferous vegetables and drink water — your liver and kidneys are doing the work either way.

Energy Cost

Real numbers from my electric bill:

• My Sun Home Solstice (1700W infrared, 45-min sessions): about $0.25–0.35 per session at $0.18/kWh
• My friend's barrel sauna (6kW electric, 30-min preheat + 25-min session): about $1.50–2.00 per session
• Wood-burning traditional: the wood itself is cheap, but you're also paying in time

Infrared wins on energy cost by a meaningful margin. Over a year of 4×/week use, that's roughly $50 vs $350.

Installation Complexity

The takeaway: infrared is dramatically easier to install in a typical American home. Most traditional cabin saunas require a 240V dedicated circuit, which often means an electrician visit and possibly a panel upgrade.

Traditional (Finnish) Saunas

This is what you want if you're optimizing for the research-backed cardiovascular adaptation. Real heat, real humidity, real löyly.

Indoor Barrel/Cabin

Indoor traditional saunas are usually paneled cedar or hemlock cabins with an electric heater. The footprint is typically 4'×4' to 6'×8'. Expect to pay $3,000–8,000 for the kit and another $500–1,500 for electrical work.

Key things to verify before you buy:

• Heater wattage matched to room size (rule of thumb: 1 kW per 1.5 cubic meters of sauna space, adjusted for insulation)
• 240V single-phase access in your electrical panel
• Ventilation — at minimum, two passive vents; better, a supply vent near the heater and an exhaust vent on the opposite wall
• Drainage — concrete pad with a floor drain is ideal; you can get by without it, but löyly water has to go somewhere

Outdoor Barrel

This is what I helped my friend build. A cedar barrel sauna with a wood-burning Harvia stove, sitting on his concrete patio. Total cost including the kit, stove, chimney, and a small concrete pad: about $6,200 in 2024.

Advantages: real wood-fired ambiance, no electrical bill, no permits in most jurisdictions for a freestanding outdoor structure under a certain square footage (check yours).

Disadvantages: it's a 45-minute light-and-wait to get to operating temperature. You need a wood supply. You're outside in whatever weather your area has. And you'd better make sure your neighbors aren't sensitive to the smoke.

Electric vs Wood-Burning

Electric is the right answer if you want to sauna at 8 PM on a Tuesday and you don't want to manage a fire. Most people should get electric.

Wood-burning is the right answer if you have outdoor space, you're willing to do the fire ritual, and you want that specific kind of smoky, crackly, profoundly-Finnish experience. It's better. It's also more work.

Premium Brands

Worth knowing about:

• Auroom (Estonia): beautifully designed modular cabins, modern aesthetic, $4,000–10,000+
• Sentiotec (Austria): excellent heaters and well-engineered cabins, $3,500–8,000
• Almost Heaven Saunas (West Virginia): well-priced US-made barrels and cabins, $3,000–8,000 — good value
• Finnleo (Finland/USA): the legacy player, $4,500–15,000+ for high-end
• Saunum (Estonia): unique air-circulation tech that's actually a meaningful improvement on standard convective designs, $4,000–9,000

For most people in North America, Almost Heaven is the best price-to-performance brand. For premium aesthetic, Auroom.

Infrared Saunas

This is what you want if you're optimizing for ease of installation, lower energy costs, daily use frequency, or a smaller footprint.

Full-Spectrum vs Near-Infrared Only

Infrared wavelengths break down into:

• Far-infrared (FIR): 8–14 micrometers, penetrates skin slightly, heats tissue. This is the workhorse of most infrared saunas.
• Mid-infrared (MIR): 1.5–5.6 micrometers. Penetrates a bit deeper than FIR.
• Near-infrared (NIR): 0.76–1.5 micrometers. Doesn't heat much directly but is being studied for photobiomodulation effects (mitochondrial function, etc.).

"Full-spectrum" saunas (Sun Home, Sunlighten, Clearlight high-end) include emitters for all three. "Far-infrared only" saunas use only carbon or ceramic FIR panels.

My take: FIR is doing most of the heat lifting. NIR has interesting but still-early research for photobiomodulation. I'd pay a modest premium for full-spectrum if budget allows, but I wouldn't make it the deciding factor.

EMF Concerns (with an Honest Take)

Infrared sauna EMF discourse is a lot. Here's what's true:

• Cheap carbon-panel infrared saunas can emit measurable AC magnetic fields, sometimes in the 30–80 mG range at the panel surface.
• The IARC classifies extremely low-frequency magnetic fields as a Class 2B possible carcinogen, based on weak epidemiological signals around childhood leukemia and residential exposure to power lines.
• Premium brands (Sun Home, Clearlight, Sunlighten) market "low-EMF" panels and typically measure 1–5 mG at body distance.

I bought a Trifield TF2 meter ($175) and measured my Sun Home Solstice. At body distance during a session, I get readings of 0.8–2.4 mG. For context, a refrigerator running pulls about 2 mG at 1 foot away.

My honest take: if you spend 45 minutes a day, four days a week in an infrared sauna, EMF exposure is worth thinking about — not panicking about. Buy from a brand that publishes third-party EMF testing, and don't sit with your back directly pressed against the panels for the full session.

Premium Brands

• Sun Home Saunas: my pick for best-in-class infrared. The Solstice (1–2 person) is what I own. Full-spectrum, low-EMF, well-built. $4,500–6,500.
• Higher Dose: great branding, decent product. The Sauna v4 cabin ($2,400) is a fair-value entry-level full-spectrum. The blanket is excellent for what it is.
• Clearlight (by Jacuzzi): premium build, excellent low-EMF panels, well-warrantied. $4,500–9,000+.
• Sunlighten: the legacy luxury brand. Beautifully built. Often overpriced — you're paying for showroom polish and a long warranty. $5,500–14,000+.

Portable Infrared Blankets / Pads

This is a real category, and it's better than skeptics think. A good infrared blanket gets your core body temperature up, drives a real sweat response, and produces most of the subjective benefits of a sauna session.

Top picks:

• Higher Dose Infrared Sauna Blanket V4: $700, well-built, low EMF claims that mostly check out. My pick for the category. See my full Higher Dose sauna blanket review for 8-month testing notes.
• MiHigh Sauna Blanket: $400–500, similar concept, slightly lower max temperature but better value
• Bon Charge Infrared Sauna Blanket: $600, decent middle option

What you give up vs a real sauna: no head/face exposure, less full-body radiant heat, no löyly humidity, no sense of ritual. What you gain: $700 instead of $4,500, fits in a closet, runs on a normal outlet.

The Contenders by Budget Tier

$300–800: Portable & Entry Infrared

Best fit: apartment dwellers, travelers, sauna-curious people who don't want to commit to a cabin.

• MiHigh Sauna Blanket ($450) — entry-level infrared blanket [Check current price →]
• Higher Dose Infrared Sauna Blanket V4 ($700) — best in category [Check current price at Higher Dose →]
• Serenelife Portable Infrared Sauna Tent ($300–400) — single-person tent with head out, basic but functional
• Durasage Personal Sauna ($350) — similar tent format, slightly better build

What you actually get at this tier: a real sweat response, a real heat-shock signal, daily ease of use. What you don't get: high temperatures, depth of feel, social use.

$1,500–3,500: Entry Cabin Saunas

Best fit: homeowners who want a real cabin, willing to dedicate floor space, don't have $5K+ to spend.

• Higher Dose Sauna v4 (2-person cabin) ($2,400) — best value full-spectrum infrared cabin [Check current price →]
• Almost Heaven Salem Barrel Sauna ($3,200) — entry-level traditional electric barrel [Check current price →]
• Dynamic Saunas Andora 2-Person Far-Infrared ($1,800) — basic infrared cabin, no full-spectrum, fine if you're budget-constrained
• Maxxus 2-Person Near Zero EMF Far Infrared Sauna ($1,900) — solid entry option

This is the tier where most people land. The Higher Dose v4 is what I'd buy if I were starting over and had a $2,500 budget.

$4,000–7,000: Premium Infrared

Best fit: people committed to daily sauna practice, want full-spectrum, low-EMF, longer warranty, better aesthetic.

• Sun Home Solstice (1–2 person) ($4,500) — my pick, what I own [Check current price at Sun Home →]
• Sun Home Equinox (3-person) ($5,800) — same build, more space
• Clearlight Sanctuary 1 ($5,500) — Jacuzzi-backed premium, excellent build
• Sunlighten mPulse Aspire ($6,500) — overpriced for what it is, but well-built

If you're spending $4K+ on an infrared sauna, you should be getting full-spectrum, third-party EMF testing, and at least a 5-year electrical warranty.

$8,000–15,000+: Custom & Premium Outdoor Traditional

Best fit: serious sauna practitioners, those building outdoor wellness setups, people who want the real Finnish experience.

• Auroom Cala Wood Outdoor Sauna ($9,500) — beautifully designed modular outdoor
• Almost Heaven Pinnacle Cabin Sauna ($8,500) — premium US-built indoor cabin
• Finnleo S-Series Custom ($10,000–15,000+) — full custom builds
• Saunum Base 6-person ($9,800) — excellent air-circulation tech
• Custom builder route: $12,000–25,000 if you hire a local sauna builder for a fully custom outdoor structure

I helped a friend spec a Finnleo Custom Cut for his basement that came in around $13,500 installed. It's the best sauna I've ever sat in. It's also far more sauna than most people need.

Outdoor vs Indoor Installation

Indoor pros: convenience, year-round use, no weather exposure, often less expensive electrical run.

Indoor cons: humidity management (traditional only — your wife will hate the bathroom mirror), real estate cost, ventilation complexity.

Outdoor pros: no interior humidity issues, more space options, often better atmosphere (looking at trees while you sauna), wood-burning option available.

Outdoor cons: weather, walking outside in February in your boxers, more complex electrical or chimney install, theft/vandalism concerns in some areas.

My setup is in the garage (semi-outdoor) — climate-controlled most of the year, no humidity in the house, but I don't have to walk outside in January. If I were building from scratch and had a backyard, I'd put the sauna outdoors with a small covered walkway.

Power Requirements (110V vs 240V — This Trips People Up)

This is the single most common mistake I see new sauna buyers make. They order a 4-person traditional sauna, get it delivered, and discover that the 6kW heater requires a 240V dedicated circuit that they don't have.

• Any infrared sauna under 1800W: usually runs on a standard 110V/15A or 110V/20A outlet
• Most 2-person infrared cabins: 110V is fine
• Most 3-person and larger infrared cabins: may need 240V
• Almost all traditional electric sauna heaters above 4.5kW: 240V single-phase, often a dedicated 30A or 40A circuit

Before you buy, check:

1. The exact electrical spec from the manufacturer
2. Your existing panel capacity (you may be near max)
3. The distance from your panel to install location (long runs are expensive)
4. Permit requirements in your jurisdiction

A typical 240V circuit install runs $400–1,200 if you have panel capacity. If you need a panel upgrade, add $1,500–4,000.

The Sauna + Cold Plunge Contrast Protocol

This is the stack most of us are building toward. Hot, then cold, repeated. There's enough to say about this that I wrote a separate guide — see the full sauna and cold plunge protocol for the details.

The short version:

• 15–20 minutes sauna at 80°C+ (or 45 min infrared at max heat)
• 1–3 minutes cold plunge at 48–55°F
• Repeat 2–3 times
• End on cold for energy/dopamine; end on hot for sleep

The mechanism is real: hot exposure drives vasodilation, cold drives vasoconstriction, and toggling between the two trains autonomic flexibility — your ability to shift between sympathetic and parasympathetic states. It's also one of the most subjectively rewarding things you can do for $0 of marginal cost once you own the gear.

Maintenance and Longevity

Infrared saunas are essentially zero-maintenance for the first 3–5 years. Wipe down the bench after each session (sweat is corrosive over time), keep dust off the heaters, check the electrical connections annually. Carbon heater panels typically have a 10–25 year lifespan.

Traditional electric saunas need slightly more attention. The heater stones should be repositioned every few months and replaced every 2–5 years depending on use. Wood-paneled interiors should be wiped down regularly and re-oiled (with sauna-safe oil) every couple of years. Drains should be cleared periodically.

Wood-burning saunas need the most maintenance: chimney cleaning annually, ash management, wood storage, fire safety.

Lifespan in real life:

• Quality infrared cabin: 15–20 years with reasonable care
• Quality electric traditional: 20–30 years (heater elements replaceable)
• Wood-burning traditional: 25+ years for the structure, stoves vary widely

How I'd Spend Your Money: Three Real Buying Scenarios

To make the budget tiers more concrete, here's how I'd advise three real readers I've talked to.

Scenario 1: "I have $2,000, I rent a townhouse, I want to start sauna practice"

Buy: Higher Dose Sauna v4 cabin ($2,400 — slightly over budget but worth stretching) OR Higher Dose Infrared Blanket ($700) plus a chest-freezer cold plunge build (~$1,200).

If you can stretch to the v4 cabin and your landlord is okay with you running it on a dedicated 110V outlet, that's a real sauna in a real cabin form factor. If $2,000 is a hard cap, the blanket-plus-plunge combo gives you contrast therapy capability and you'll get more total benefit than from a sauna alone.

Scenario 2: "I own a home, I have $8,000, I want the longevity-protocol setup"

Buy: Sun Home Solstice ($4,500) plus Plunge All-In ($4,990) — slightly over, but this is the setup I'd build if I were starting over. Best-in-class infrared, turnkey cold plunge, no DIY headaches, lifetime infrastructure.

Alternative: Almost Heaven Salem Barrel Sauna ($3,200) plus DIY chest-freezer plunge ($1,200) plus electrical work ($800) = $5,200, leaving budget for accessories and the Trifield meter. This puts you in the traditional-sauna camp with the strongest research backing.

Scenario 3: "I have $15,000, this is the dream setup, what should I build?"

Buy: Auroom Cala Wood Outdoor Sauna ($9,500) plus Plunge All-In ($4,990) plus a small covered walkway and concrete pad ($500–1,500 DIY).

Year-round outdoor practice. Real Finnish heat. Real cold plunge. The setup most adjacent to what well-funded longevity clinics actually run.

If you want infrared instead of traditional at this budget, swap the Auroom for a Sun Home Equinox ($5,800) and put the savings into a Clearlight cold plunge bath or upgraded interior finishes.

What I Got Wrong When I Was Starting

A short list of mistakes I made in years one and two, in case you can skip them:

1. I obsessed about EMF and bought a meter before I bought a sauna. Get the sauna first, then verify your specific unit. Most premium brands deliver on their EMF claims.
2. I bought a sauna too small. The 1-person tent I started with was unsatisfying. The blanket replaced it within 6 months. If your budget is in tent range, get a blanket instead.
3. I tried to use traditional heat (80°C+) before I'd built tolerance. Felt sick for hours after my first session. Build up over weeks, not days.
4. I didn't measure anything. Heat-up time, session length, frequency — I was vague about all of it for months. The moment I started logging, the practice got much better. Track what you do.
5. I assumed "more is better." It isn't. 4×/week at 20 minutes is better than 7×/week at 30 minutes for most people. Recovery from heat exposure matters.

FAQ

For the cardiovascular and longevity benefits in the Finnish data, 4+ times per week, 19+ minutes per session, at 80°C+ for traditional. For infrared, aim for 30–45 minute sessions at the maximum the unit will reach (typically 60–65°C). Less than 2 sessions per week shows minimal benefit in the research.

For cardiovascular adaptation specifically — probably not at equivalent session lengths, based on the lower core-temperature response. For subjective recovery, mood, sleep, and ease of integration into daily life — yes, often better. The "best" sauna is the one you'll actually use four times a week. If that's infrared because traditional is too hot or too inconvenient, get infrared.

After. Pre-workout sauna can compromise resistance-training performance via dehydration and cardiovascular load. Post-workout sauna stacks well with the heat-shock response and may modestly enhance recovery. Avoid sauna immediately before sleep if you're sensitive to elevated core temperature lingering — finish 1–3 hours before bed.

Subjectively, many people experience infrared sweating as starting earlier in the session and feeling different. Objectively, sweat composition is roughly the same — sweat is mostly water and electrolytes regardless of how you got hot.

A real concern with cheap units, mostly mitigated by buying from brands that publish third-party EMF measurements (Sun Home, Clearlight, Sunlighten low-EMF lines). At body distance during a session, you want readings under 3 mG. A Trifield TF2 meter is $175 if you want to verify yourself.

Probably an infrared blanket or small infrared tent, yes. Probably a cabin sauna, no — you'll have power and weight issues, and your landlord and neighbors will have opinions. Tenant-friendly sauna means a blanket.

If you can only do 1–2 sessions per week, do them. They're better than nothing. But understand that the strong mortality signal in the Finnish data shows up at 4+ sessions per week. Frequency is the limiting variable for most people.

Wood-burning is a better experience. Electric is a better lifestyle fit for almost everyone. If you have the outdoor space, the time, the wood supply, and the patience, wood is wonderful. Otherwise, electric.

For someone who'll use it 4+ days a week for 5+ years, yes. For occasional use, no — a $700 Higher Dose blanket gets you most of the way there. I cover this in detail in my Sun Home Solstice review.

If budget allows and you'll use both, yes — the contrast is more than the sum of its parts. If you can only have one, sauna has the stronger longevity research, but cold plunge has stronger acute mood effects. See my cold plunge guide for the cold side of the equation.
