The SaunaBox Solara and the JNH Lifestyles Joyous 1-Person are both single-person infrared saunas built from Canadian hemlock and designed for home use. The Solara delivers full-spectrum infrared (near, mid, and far) with a V2 medical-grade red light panel at 660 nm and 850 nm, assembles in under 30 minutes with no tools, and is priced at $2,699. The JNH Joyous is a far-infrared-only cabin with six carbon fiber heaters, a 140°F ETL-limited max temperature, and a price of $2,199. Here is how every published spec compares.

What is the real difference between these two 1-person infrared saunas?
Direct answer
The core difference is infrared spectrum coverage and red light therapy. The SaunaBox Solara delivers near, mid, and far infrared wavelengths plus a dedicated 660 nm and 850 nm red light panel. The JNH Joyous delivers far infrared only with no red light component. Everything else, including wood type, Bluetooth audio, and standard outlet power, is similar between the two cabins. The $500 price gap reflects that spectrum difference.
Far infrared (FIR) operates in the 5.6 to 15 micrometer wavelength range and penetrates approximately 1.5 inches into tissue. It raises core body temperature, promotes sweating, and supports circulation. Most budget infrared saunas use far infrared exclusively because carbon fiber heaters naturally emit in this range.
Full-spectrum infrared adds near-infrared (NIR) and mid-infrared (MIR) wavelengths. Near-infrared at 700 to 1400 nm penetrates deeper into tissue and is associated with cellular energy production and wound healing in photobiomodulation research. Mid-infrared targets soft tissue and joints at intermediate depths. A full-spectrum system gives the user access to all three bands in a single session.
The SaunaBox Solara lists near, mid, and far infrared on its spec sheet. It also includes a separate V2 red light panel at 660 nm and 850 nm. These are the two wavelengths most studied in photobiomodulation research, with 660 nm targeting skin-level tissue and 850 nm penetrating into muscle and joint tissue. The panel uses a swivel mount so users can direct the light at specific areas during a session.
The JNH Joyous uses six carbon fiber heaters that emit far infrared only. The optional chromotherapy light (+$99) provides colored LED mood lighting in 12 colors. Chromotherapy is not the same as red light therapy. It does not deliver the specific 660 nm or 850 nm wavelengths studied in clinical photobiomodulation research, and JNH does not make therapeutic claims for it.
For buyers who want infrared heat only and do not need red light therapy or multi-spectrum coverage, the JNH Joyous delivers that at a lower price. For buyers who want the broadest possible wavelength coverage in a single unit, the Solara provides full-spectrum infrared plus dedicated red light in one cabin.
How does max temperature compare?
Direct answer
The SaunaBox Solara reaches 150°F, published on the official product page. The JNH Joyous is limited to 140°F by an ETL safety standard built into the control panel. JNH confirms this limit in their FAQ section: "The 140°F limit is an ETL safety standard built into the control panel."
A 10-degree difference matters for users who want higher heat intensity during shorter sessions. At 150°F, the Solara allows users to reach a deeper sweat faster. At 140°F, the JNH Joyous is designed for longer sessions of up to 60 minutes at a moderate, sustained temperature. Neither temperature is unsafe for healthy adults, but the Solara gives users more range to work with.
How does assembly compare?
Direct answer
The SaunaBox Solara ships as four pre-assembled panels with pre-installed clips. No tools are required. Assembly takes under 30 minutes from box to built. The sauna plugs into any standard household outlet with no electrician needed.
The JNH Joyous uses a tongue-and-groove modular construction system. JNH describes it as "easy assembly" and "simple break down to move" but does not publish a specific assembly time on the product page. The JNH cabin weighs 246 lbs and ships on a pallet, which means getting it into position requires planning. The Solara does not publish its weight, but the 4-panel clip system is designed for a single person to assemble without help.
How do certifications and safety testing compare?
Direct answer
The SaunaBox Solara publishes multiple third-party certifications with linked test reports on its product page. The Solara is IEC 62233 certified by Intertek for ultra-low EMF, California Proposition 65 compliant, and independently tested to be free of toxic heavy metals and phthalates. Both test reports are downloadable PDFs linked directly on the product page.
The JNH Joyous publishes an EMF rating of less than 8 mG. The 140°F temperature limit indicates ETL certification, which is a North American safety standard. JNH does not link specific test reports on the product page, and no additional certifications beyond ETL are mentioned. For buyers who want to review the actual lab documentation before purchasing, the Solara provides that transparency.

Frequently asked questions
For buyers who want full-spectrum infrared, red light therapy, faster assembly, and third-party safety certifications with linked reports, the Solara is the stronger choice. For buyers who want a taller cabin, lower price, and are satisfied with far-infrared-only heat, the JNH Joyous delivers solid value at $500 less. Neither is objectively better across every category.
No. The JNH Joyous does not include red light therapy. It offers an optional chromotherapy light (+$99) that provides colored LED mood lighting in 12 colors. Chromotherapy is not the same as red light therapy. It does not deliver the 660 nm or 850 nm wavelengths used in photobiomodulation research.
Yes. The Solara spec sheet lists near, mid, and far infrared wavelengths. It also includes a separate V2 red light panel at 660 nm and 850 nm with a swivel mount for targeted therapy. The JNH Joyous uses far infrared only from carbon fiber heaters.
The JNH Joyous maxes out at 140°F. This limit is an ETL safety standard built into the control panel, confirmed in the JNH FAQ section. The SaunaBox Solara reaches 150°F. The 10-degree difference gives Solara users more heat range for shorter, higher-intensity sessions.
Under 30 minutes. The Solara ships as four pre-assembled panels with pre-installed clips. No tools, no drills, no professional help required. It plugs into any standard household outlet. The JNH Joyous uses tongue-and-groove construction but does not publish a specific assembly time.
The Solara is IEC 62233 certified by Intertek for ultra-low EMF, California Proposition 65 compliant, and independently tested to be free of toxic heavy metals and phthalates.

The SaunaBox Solara is $2,699 (sale from $3,000). The JNH Joyous is $2,199. The $500 difference buys you full-spectrum infrared, red light therapy, IEC 62233 certification, Prop 65 compliance, and HSA/FSA eligibility. If you use HSA/FSA funds on the Solara, the effective out-of-pocket cost may be lower than the JNH depending on your tax bracket.
