Top Sauna Brands Compared
Discover which leading sauna brands deliver the best heat, quality, and value to help you find your perfect sweat session.
The best sauna brands PPW carries are Medical Breakthrough and Golden Designs Inc. Medical Breakthrough leads on health-focused design and feature depth, while Golden Designs excels in outdoor-ready traditional construction. Your choice depends on sauna type, capacity, and installation setting rather than brand prestige alone.
- A brand worth taking seriously has consistent wood species, documented heater specs, and honest guidance on electrical requirements, not vague installation notes.
- Full-spectrum vs. single wavelength: Full-spectrum infrared produces near, mid, and far wavelengths at once, which matters if longer, more comfortable sessions are the goal rather than raw heat output.
- 120V removes the electrician: A unit that runs on a standard 120V outlet skips the dedicated circuit requirement entirely, which is a real advantage for renters or anyone who cannot add a dedicated line.
- Wall thickness is functional: One-and-a-half-inch walls retain heat more effectively through outdoor temperature swings than thinner panel construction, making that spec worth checking before you buy.
- No single brand wins every category, so the better question is which brand built the right product for your space, session style, and installation constraints.
Where to start
Medical Breakthrough 7 Plus 4-6 Person Infrared Sauna - Full-Spectrum, Chromatic Therapy & Audio System
Golden Designs Kaarina 6 Person Barn Outdoor Traditional Sauna (GDI-8506-01)
What Separates a Serious Sauna Brand from the Rest
Plenty of companies sell saunas. Far fewer actually build them well. The difference shows up in the details: how the wood is selected and dried, how the heater is sized to the cabin volume, how the electrical components are rated, and what the warranty actually covers when something goes wrong three years in.
A brand worth considering has a clear manufacturing story. That means a consistent wood species across the line, documented heater specifications, and controls that function reliably in a high-humidity or high-heat environment. It also means honesty about installation requirements, because a sauna that needs a dedicated 240V/40A circuit and arrives with vague electrical guidance is a problem waiting to happen.
This comparison covers the brands PPW carries, drawing on real specification data from each manufacturer's documentation. The goal is to help you understand what each brand does well, where their products fit in your life, and which one actually matches your space, budget, and intended use.
Medical Breakthrough: Built Around the User Experience
Medical Breakthrough designs saunas with input from medical professionals, and that focus shows in the feature set. Their units tend to prioritize comfort and accessibility alongside thermal performance. The Medical Breakthrough 7 Plus, for instance, accommodates up to six people in a hemlock wood cabin fitted with full-spectrum infrared heaters, chromatic therapy lighting, and an integrated audio system. Those aren't luxury add-ons bolted on as an afterthought; they're part of a deliberate design to make longer sessions more sustainable.
Full-spectrum infrared means the unit produces near, mid, and far infrared wavelengths simultaneously. Near infrared penetrates more shallowly and is associated with skin-level effects; far infrared reaches deeper tissue and is more closely linked with the cardiovascular and sweating effects that most people associate with sauna use. Combining all three gives the user flexibility without needing to choose between sauna types.
Their Traditional 7 v2a is a different kind of product: a three-person traditional unit built from 100% natural Canadian Hemlock wood, with an Ultra-High Performance Stove capable of reaching 194°F. It includes the Rapid Internal Heating System, which the brand claims brings the cabin up to temperature quickly, and the Safe Cool Down System, which gradually steps the temperature back after a session. That second feature is less common than it sounds and is worth noting for anyone who uses the sauna late in the evening and wants a safer, more gradual transition.
Medical Breakthrough saunas sit at the higher end of the price range, with the 7 Plus priced at $12,799 and the Traditional 7 v2a at $10,799. That reflects the heater quality, feature depth, and construction standards rather than marketing. If you want a unit that's been thought through from a health-outcome perspective rather than just a heat-delivery one, this brand deserves serious attention.
Golden Designs: Traditional Heat, Outdoor-Ready Construction
Golden Designs focuses on outdoor traditional saunas, and their Barn Series is the product line most people encounter first. These are all-weather cabin structures with Canadian Red Cedar interiors, a wood species chosen for its natural resistance to moisture and its distinctive, invigorating aroma. Cedar's dimensional stability in fluctuating temperatures makes it a sensible choice for an outdoor installation that will cycle between hot sessions and cold nights.
Both of their Barn Series models in this comparison run on an 8.0 kW stove with built-in controls. That stove size is appropriate for a six-person cabin (the Kaarina, priced at $10,599) and is on the powerful end for a three-person unit (the Savonlinna at $8,999). The generous heater capacity in the smaller model means faster heat-up and a more consistent temperature under load, which matters when you're running sessions back-to-back. The ideal operating range for both is 170 to 185°F, with a maximum of 190°F.
Both units require a 240V/40A circuit for the stove and a separate 120V/15A circuit for lighting and audio. If you're planning an outdoor installation, budget for a licensed electrician to run two dedicated lines before the sauna arrives on the pallet. Delivery is curbside freight, so factor in the logistics of moving the unit from the driveway to your installation site.
The interior amenities are competitive: galaxy star color therapy lighting, an LED control panel with FM radio and Bluetooth, built-in speakers, and the traditional accessories (sandglass, bucket, and scoop) are all included. The bronze privacy tempered glass door is a practical detail that gets overlooked in comparisons but matters for anyone locating the sauna in a shared outdoor space.
Auroom: A Kit-First Approach to Modular Sauna Design
Auroom builds saunas as installation kits, and that approach suits a specific buyer: someone who wants a premium result but also wants control over the installation process and the long-term cost.
Their material choices are considered. The Cala Glass line uses either standard Aspen or Thermo-Aspen, a heat-treated variant that has improved dimensional stability and a darker finish. Thermo-treatment drives moisture from the wood and changes its cellular structure, making it more resistant to warping and better at tolerating the repeated expansion-contraction cycles that come with daily sauna use. The Aura line uses Black Thermo-Spruce, which offers a more dramatic visual aesthetic alongside the same functional benefits.
Capacity ranges from one person (the Cala Glass Mini, starting at $7,190) up to six (the Familia, at $11,990), with the fully assembled Arti cabin for five people sitting at the top of the line at $38,990. That last option is a different product category entirely: a pre-built outdoor structure rather than a kit, positioned for buyers who want a turnkey outdoor sauna without any assembly. The Cala Glass 4-person kit, by contrast, is designed for two-person assembly in approximately four to six hours.
Auroom's glass-panel designs are also worth noting for aesthetic reasons. The Cala Glass line features a significant glazed front wall, which brings natural light into the cabin and makes the space feel less enclosed. For people who find windowless sauna cabins uncomfortable, this is a meaningful functional difference, not just a visual one. You can browse the full range of saunas to compare Auroom's configurations against other brands side by side.
Finnmark: Infrared and Steam in the Same Cabinet
Finnmark occupies an unusual position in this category. Their Trinity series combines full-spectrum UL Listed infrared heaters, a traditional steam heater, and red light therapy in a single unit. That combination addresses a genuine question: infrared and traditional steam produce different physiological responses, and choosing between them usually means committing to one approach. Finnmark's design lets you use whichever mode fits the session.
The FD-4 Trinity (a two-person unit) runs the infrared panels, red light therapy, and a 1.9 kW traditional heater all from a standard 120V outlet. No electrician required, which removes a significant barrier for renters or homeowners who can't add a dedicated circuit. The FD-5 Trinity XL scales up to a four-person cabin with a 4.5 kW traditional heater on a 240V/1PH circuit, which is the more typical electrical requirement once you move above a two-person format.
The infrared panels on both units are rated to reach 170°F in under an hour on a standard outlet, which is consistent with what full-spectrum infrared can realistically achieve. Studies on infrared sauna use generally find benefits at temperatures between 130°F and 160°F, so the lower operating temperature of infrared versus traditional steam is not a limitation from a therapeutic standpoint.
Red light therapy (technically photobiomodulation) operates at wavelengths between 630 and 850 nanometers. Research on this modality is ongoing, but several well-designed studies document improvements in skin condition and muscle recovery with regular exposure. Having it built into the sauna rather than as a separate device is a convenience worth considering if you already use or plan to use red light panels.
Dundalk LeisureCraft: Outdoor Cabin Construction with Cedar and White Cedar
Dundalk LeisureCraft specializes in outdoor cabin saunas built from premium North American wood species. Their Granby model, a two-to-three person outdoor cabin, uses Eastern White Cedar with 1.5-inch thick walls and roof boards. That wall thickness is a practical specification, not a marketing claim: thicker walls retain heat more effectively and handle outdoor temperature swings better than thinner panel construction.
Their indoor Element series takes a different approach. The Nook (a two-person unit compatible with a 4.5 kW electric heater) and the Element Loft (a three-person unit designed exclusively for a 6 kW heater) are sized for dedicated indoor sauna rooms, fitness spaces, or wellness studios. The larger Element Studio, a four-person unit, also specifies a 6 kW electric heater and is positioned for boutique hotels and spa installations as well as home use.
The Georgian is the brand's flagship outdoor cabin: a six-person structure with 343 cubic feet (9.7 cubic meters) of interior volume. That's a substantial space, and the volume figure is useful for heater sizing because traditional sauna heaters are typically rated by the cubic footage they can adequately heat. Matching heater output to cabin volume is one of the more important technical decisions in sauna installation, and Dundalk's published volume figures make that calculation straightforward.
For buyers weighing a cabin sauna against a barrel format, the structural differences come down to heat distribution, ceiling shape, and footprint. How each form factor handles heat retention and airflow is worth reading through before committing to either shape.
SaunaLife: Glass and Ergonomics in a Barrel Format
SaunaLife builds outdoor barrel saunas, and their design philosophy distinguishes them from most barrel manufacturers. The EE8G, a six-person barrel, features an 8mm tempered glass front wall that fills the interior with natural light. Most barrel saunas use a solid wood end cap or a small porthole window; the full glass wall is a genuine departure that changes the character of the sauna experience significantly.
Barrel construction has a structural advantage over rectangular cabins in outdoor settings: the cylindrical shape provides inherent structural rigidity without the need for a traditional frame, and the curved ceiling naturally circulates hot air toward the center where users sit. The trade-off is floor space efficiency, since the curved floor-to-wall junction reduces usable bench area compared to a flat-sided structure of the same external diameter.
For buyers deciding between a barrel and a cabin-style outdoor sauna, the structural and installation differences between outdoor sauna formats are worth understanding before choosing. Barrel saunas tend to be faster to install and easier to relocate; cabin saunas tend to offer more interior headroom and flexibility in bench configuration.
North Shore Sauna: Portable and Wood-Burning for Outdoor Sessions
North Shore Sauna takes a fundamentally different approach to the category. Their Nova and Dome series are tent-style portable saunas powered by wood-burning stoves, not electric heaters. The Nova 6 tent measures approximately 7.5 by 9 feet with a 32-inch door, large enough to seat six people on two portable cedar and aluminum benches. The Dome can hold 70 to 80 pounds of sauna rocks, which affects how much steam the stove can generate when water is poured.
The headline specification for the portable line is heat-up time. North Shore's wood-burning tents are documented to reach 180 to 200°F in approximately 15 minutes, which is faster than any electric unit in this comparison. That's a function of the wood stove's output and the tent's relatively small insulated volume rather than a magic engineering trick, but it's still a meaningful practical advantage for anyone who wants a spontaneous session rather than a scheduled one.
The trade-off is obvious: you need a supply of dry firewood, a safe outdoor space for open-flame use, and an acceptance that this is a different ritual than stepping into a finished cabin. For buyers who want a traditional wood-fired sauna experience without a permanent structure, these tents deliver that authentically. For buyers who want something to use year-round in any weather without tending a fire, a fixed electric unit is the more practical choice.
The Pro and Elite Experience packages include accessories like the 5L aluminum bucket with bamboo handle, ladle, thermometer, hygrometer, firewood carrying bag, and a fireproof floor mat. The hardware is functional rather than decorative, and the package pricing reflects that approach.
Side-by-Side: Auroom Models Compared
The Auroom range illustrates how much variation exists within a single brand. Here's how the current lineup stacks up across capacity, wood type, and price.
| Model | Capacity | Wood Type | Format | Price |
|---|---|---|---|---|
 Auroom Cala Glass Mini |
1 person | Aspen | Kit | $7,190 |
| Auroom Cala Glass Mini (Thermo) |
1 person | Thermo-Aspen | Kit | $7,590 |
 Auroom Baia |
2 persons | Aspen | Kit | $7,990 |
 Auroom Cala Wood (Thermo) |
2 persons | Thermo-Aspen | Kit | $7,790 |
| Auroom Cala Glass 4-Person |
4 persons | Aspen | Kit | $7,990 |
 Auroom Familia 6-Person |
6 persons | Not published | Kit | $11,990 |
The pricing structure within Auroom's kit line is not strictly capacity-based. The four-person Cala Glass in standard Aspen and the two-person Baia both list at $7,990, which suggests the glass front wall carries a cost premium that the larger format absorbs differently. The Thermo-Aspen upgrades consistently add $400 to $500 over their standard Aspen equivalents. The Arti's jump to $38,990 reflects the shift to a factory-assembled structure rather than a DIY kit.
How to Match a Brand to Your Situation
No single brand wins across every category, because the categories don't overlap cleanly. The right question isn't "which brand is best" but rather "which brand built the right product for what I'm actually doing."
If you want an indoor infrared sauna with therapeutic features and don't want to think about electrical installation beyond a standard outlet, Finnmark's two-person Trinity series handles that cleanly. If you want a large outdoor traditional sauna that can handle a full family or small group, Golden Designs and Dundalk LeisureCraft both deliver that, though in slightly different construction styles. Golden Designs leans into the complete experience with built-in audio and color lighting; Dundalk focuses on wood quality and structural durability.
For buyers who want to build something themselves and control the end result, Auroom's kit system is the most logical path. The assembly documentation is designed for two people over a half-day, and the modular approach means you can match the size and wood treatment to your specific space and humidity conditions. If you eventually decide that what a sauna kit actually includes matters to your decision, that comparison is worth reading before you commit.
Medical Breakthrough is the strongest choice for buyers who prioritize the full-session experience: rapid heat-up, controlled cool-down, combined therapy features, and a design that makes regular use genuinely comfortable rather than just functional. The price reflects that depth. North Shore Sauna is the correct answer for anyone who wants a wood-fired portable setup that goes up in 15 minutes and comes down when the season ends.
If you're still deciding between a traditional steam sauna and an infrared model, how traditional saunas perform in home settings is a useful frame for that decision. The heat type affects everything from session length to electrical requirements to the type of physiological response you're working toward.
One practical consideration that doesn't always come up in brand comparisons: the outdoor sauna category and the cold plunge category often go together. Regular contrast therapy, alternating between high heat and cold immersion, has a well-documented effect on cardiovascular response and recovery. If you're building out a full outdoor wellness setup, the outdoor saunas range pairs naturally with cold plunges, and thinking about both installations at the same time saves a significant amount of planning effort later.
Capacity planning is also worth getting right on the first attempt. Undersized saunas are one of the most common buyer regrets in this category, and the problem isn't always space; sometimes it's future use. A two-person unit bought for solo use becomes frustrating the first time you want to share a session. For four-person and above configurations, how four-person outdoor saunas differ in footprint and heater requirements is a concrete starting point for getting the sizing right.

Frequently asked questions
Which sauna brands does Peak Primal Wellness carry, and what makes each one worth considering?▾
PPW carries two sauna lines, each aimed at a different buyer. The first is designed with documented input from medical professionals, emphasizing feature depth and thermal performance across both infrared and traditional formats. The second focuses on outdoor-ready traditional cabins, with Canadian Red Cedar interiors, robust stove sizing, and all-weather construction built for real outdoor conditions.
Are these saunas suitable for someone who has never owned one before?▾
Both brands include user-friendly interior LED control panels, integrated audio, and lighting systems that make the experience accessible without a learning curve. The Medical Breakthrough Traditional 7 v2a also includes a Safe Cool Down System that gradually steps the temperature back after a session, which is a genuinely useful safety feature for new users who may not know how to wind down properly after high-heat exposure.
What electrical requirements should I plan for before the sauna arrives?▾
The Golden Designs Barn Series models each require two dedicated circuits: a 240V/40A circuit for the stove and a separate 120V/15A circuit for the lighting and audio controls. You will need a licensed electrician to run both lines before installation. Treating electrical prep as an afterthought is one of the most common and costly mistakes buyers make with full-size traditional saunas.
What do these saunas cost, and what does the price reflect?▾
The Golden Designs Savonlinna 3-person outdoor sauna is priced at $8,999, the Kaarina 6-person model at $10,599, the Medical Breakthrough Traditional 7 v2a at $10,799, and the Medical Breakthrough 7 Plus infrared sauna at $12,799. Higher prices correspond to heater technology, wood quality, feature depth, and construction standards rather than brand prestige alone.
How do I choose the right size sauna for my space and household?▾
Capacity labels are a starting point, not a guarantee of comfort. A 3-person sauna like the Medical Breakthrough Traditional 7 v2a or the Golden Designs Savonlinna works well for a couple or solo user who wants generous space per person. The 6-person models from both brands suit families or households that plan group sessions regularly. For outdoor traditional models, the more important sizing factor is stove output relative to cabin volume: both Golden Designs Barn Series units use the same 8.0 kW stove, which means the Savonlinna heats faster and holds temperature more consistently under load.
What ongoing costs should I expect after the initial purchase?▾
Traditional saunas draw significant power from a dedicated 240V/40A circuit, so electricity is the primary recurring cost. The 8.0 kW stoves in the Golden Designs models give a clear reference point for calculating per-session energy use based on your local rate. Wood maintenance is minimal with cedar and hemlock, but periodic bench cleaning and checking the stove components for scale or mineral buildup is good practice, especially in areas with hard water.
What maintenance does a sauna actually need over time?▾
Both cedar and hemlock are low-maintenance wood species, and neither should be sealed or varnished inside a sauna cabin since that traps heat and defeats the material. Routine upkeep involves wiping down benches after use, airing the cabin between sessions, and inspecting the stove and electrical connections annually. For outdoor models like the Golden Designs Barn Series, checking the exterior cladding and door seals seasonally will extend the structure's lifespan considerably.
What are the most common mistakes buyers make when purchasing a sauna at this level?▾
Underestimating the electrical prep is the most frequent issue: arriving at delivery day without the correct circuits in place delays installation and adds cost. For outdoor models, failing to plan how the curbside pallet delivery gets from the driveway to the installation site is a close second. On the product side, choosing capacity based purely on the person count rather than how the stove output matches the cabin volume often leads to disappointing heat-up times, especially in colder climates.
