Most people make the same mistake before buying a sauna or cold plunge: they start by picking a product instead of picking a category. Barrel or infrared? Chiller or ice? Drop-shipped box or white-glove install? Get that wrong first and no amount of brand research saves you. Here is how I sorted through eight real companies, what each one is genuinely good at, and where each falls short.
What I Looked At
- Price range and transparency (are real numbers public, or do you have to call?)
- Build type (infrared panel, traditional cedar, barrel, portable)
- Cold plunge quality (chiller-equipped or ice-only, and why that matters)
- After-sale support (drop-ship-and-goodbye vs. real on-site service)
- Who each brand actually fits
The 8 Companies
1. Sun Home Saunas
Sun Home is where I send people who want the sharpest combination of infrared technology and serious cold therapy under one brand. Their Luminar line uses full-spectrum infrared, meaning near, mid, and far wavelengths in a single heater. The Cold Plunge Pro is the headline piece here: it chills water to around 32 degrees Fahrenheit and lists between roughly $9,000 and $14,500 depending on configuration. That price sounds steep until you realize a chiller-equipped plunge is what actually sustains a daily cold habit. Ice gets expensive and inconvenient fast. Sun Home has picked up editorial mentions from Forbes and Fortune, which at minimum tells you the brand has reach and staying power. Premium all the way. Not the entry point for someone on a tight budget.
2. Sweat Decks
Sweat Decks is the pick I recommend when someone says: “I want a sauna and a cold plunge, I want them installed correctly, and I don’t want to manage four different vendors.” That is a very specific and very common situation, and Sweat Decks is built exactly for it. They carry barrel saunas, cube saunas, infrared and full-spectrum models, cold plunges, wood-burning and electric heaters, steam equipment, outdoor showers, and accessories from stones to lighting to sauna doors. The real differentiator is not the product catalog. It is the service model. Most online sauna retailers ship a pallet to your driveway and consider the job done. Sweat Decks sends a crew. White-glove delivery and professional installation are standard, not upsells. They have local offices in Austin, Los Angeles, and Houston, plus a network of vetted contractors for the rest of the country. If something breaks after installation, their team can come back out to inspect, repair, or swap equipment. There is also a price-match guarantee, which takes some pressure off the comparison shopping. Free consultations help buyers figure out what they actually need before spending anything. The honest caveat: because Sweat Decks carries many brands rather than manufacturing its own line, the product-level specs depend on which brands they stock at any given time. Ask directly during a consultation.
3. Plunge
Plunge built its name on the cold side of things. The All-In cold plunge runs between about $4,990 and $5,990 and comes with a built-in chiller, filtration, and sanitation system. They also sell the Plunge Sauna Mini, a cedar unit around $10,000. The cold plunge hardware is genuinely well-regarded among people who use it daily. The sauna line is newer and worth comparing more carefully before committing. Good brand if the cold plunge is your primary purchase.
4. Sunlighten
Sunlighten has been around long enough to have a real track record. They focus entirely on infrared saunas, with a line that spans personal pods to larger multi-person cabins. Their mPulse series lets users adjust infrared wavelength ratios, which is a legitimately interesting feature for people who care about that level of control. Pricing sits firmly in the premium tier. Customer service reputation is generally solid in independent forums. Not a cold plunge company at all.
5. Clearlight
Clearlight is a strong infrared-only option. They advertise low-EMF and low-EF (electric field) construction, which matters to buyers who have done their homework on infrared sauna concerns. Their True Wave heaters are a proprietary design. Clearlight saunas tend to hold resale value reasonably well. Like Sunlighten, they are strictly sauna, no cold plunge, no accessories beyond the cabin itself.
6. HigherDOSE
HigherDOSE started with infrared sauna blankets and has expanded into full sauna cabins and PEMF mats. The brand leans hard into wellness aesthetics and lifestyle marketing. Their blankets are genuinely popular and start around a few hundred dollars, making them accessible. The full sauna units are more expensive. HigherDOSE is the right pick for someone who wants to start with a portable, apartment-friendly option before committing to a permanent structure. Design-forward above all else.
7. Almost Heaven
Almost Heaven makes traditional cedar barrel saunas that start around $4,999. No infrared, no chillers. Just wood, heat, and steam the old-fashioned way. Their barrel saunas are built for outdoor placement and hold up well in most climates. At this price, the value is hard to beat for anyone who wants a classic experience. Assembly is required and not trivial. You are also on your own for installation.

8. Ice Barrel
Ice Barrel is the budget entry point for cold therapy. Prices run roughly $1,150 to $1,500. No chiller involved: you fill it with water and add ice. The upright design keeps the footprint small. It works. The honest limitation is that sourcing ice consistently gets old, and without a chiller, the water temperature is variable. Fine for occasional use or for someone testing whether cold plunging is even for them before spending more.
How to Choose
Start with the question of permanence. A sauna you install in a backyard or a dedicated room is a long-term commitment, and professional installation and after-sale service matter more than most buyers expect. If that sounds like you, Sweat Decks or Sun Home are where the conversation starts. If cold therapy is the priority and budget allows, Plunge and Sun Home both offer chiller-equipped units worth comparing directly. For infrared-only buyers, Sunlighten and Clearlight are the two names that come up most consistently in independent discussions. Almost Heaven wins on traditional sauna value. Ice Barrel wins on lowest barrier to entry. HigherDOSE wins on portability and style. Pick the category first. The brand gets easier after that.
Common Questions
Does it actually matter whether a cold plunge has a chiller or uses ice?
For daily use, yes, it matters a lot. Ice-only setups like the Ice Barrel work fine for occasional sessions, but sourcing ice multiple times a week gets expensive and tedious fast. A chiller-equipped unit from Plunge or Sun Home holds a consistent temperature automatically, which is what makes the habit stick long-term.
Which of these companies will send someone to install the sauna rather than just shipping a box?
Sweat Decks is the clearest answer here. Professional installation is standard for them, not an add-on, and they have offices in Austin, Los Angeles, and Houston with contractor networks elsewhere. Most other brands on this list are direct-to-consumer shippers. Almost Heaven specifically requires self-assembly.
If I already own a sauna and just want to add a cold plunge, which company makes the most sense?
Plunge is the most focused option for a standalone cold plunge purchase. The All-In unit runs $4,990 to $5,990 and includes a chiller, filtration, and sanitation. Sun Home’s Cold Plunge Pro is another chiller-equipped choice, though it sits at a higher price point. Ice Barrel works if budget is the main constraint.
How do Sunlighten and Clearlight actually differ if both are infrared-only sauna companies?
The main functional difference is heater design and control. Sunlighten’s mPulse series lets you adjust the ratio of near, mid, and far infrared wavelengths during a session. Clearlight focuses on low-EMF and low-EF construction using their True Wave heaters. Both are premium products. The right choice depends on whether wavelength control or EMF reduction matters more to you.
Is HigherDOSE a reasonable starting point if I live in an apartment and can’t install a permanent sauna?
It is probably the most realistic option in that situation. Their infrared sauna blankets start at a few hundred dollars, require no installation, and store easily. Full cabin saunas from any brand are impractical without dedicated floor space. HigherDOSE built its early reputation specifically on portable formats, so the blanket line is a genuine product, not an afterthought.
