SaunaBox vs Vital+ · Solara vs XEN
Independently tested. £3,095 less, and twice the warranty.
Two 1-person hemlock cabins can look alike on paper. Here is where the SaunaBox Solara and the VITAL+ XEN actually differ: third-party testing, where the red light is made, warranty, size and price, using each brand's own published information.

The short answer
Both are 1-person, 100% Canadian Hemlock, full spectrum cabins that reach practically the same heat (158°F vs 160°F). The Solara's red light is made in an FDA-registered facility, its ultra-low EMF is certified by Intertek (IEC 62233), and it is certified free of toxic heavy metals and phthalates. It also costs £3,095 less, comes with a 2-Year warranty instead of 1 year, and takes up less room. The XEN adds more light modes. For one cabin in a real home, the Solara is the stronger buy.

VITAL+ figures from us.getvitalplus.com; SaunaBox figures from saunabox.com; both retrieved September 14, 2026. "Not published" means the figure is not listed on the VITAL+ product page. Prices change, so check both sites before you buy.
Two hemlock cabins. One publishes its testing.
On paper, these two look close. Both are 1-person indoor cabins built from 100% Canadian Hemlock, both run near, mid and far infrared with 660nm + 850nm red light, and both plug into a standard 110V outlet.
Where they split is what has been independently checked. The Solara's red light is made in an FDA-registered facility. Its ultra-low EMF is certified by Intertek to the IEC 62233 standard, and Intertek certified it free of toxic heavy metals and phthalates under California Prop 65.
VITAL+ lists ETL, CTI and CE certification for the XEN and describes it as ultra-low EMF. Its product page does not publish an EMF test standard, heavy metals or phthalates testing, or an FDA-registered facility for the red light.
The XEN adds a red light panel on an extendable robotic arm, plus 16 chromotherapy modes against the Solara's 10 colours.
And the Solara costs less. On September 14, 2026 it was against $3,095 for the XEN Standard.
Two years of cover, without paying extra for it
The Solara ships with a 2-Year warranty. The XEN's standard warranty is 1 year.
VITAL+ sells an extra year for $145. Add it to match the Solara's cover and the XEN comes to $3,240.
That is £3,240 more than the Solara for the same two years of cover.
On a cabin you plan to sit in most days, the second year is the one you want in writing.
Will it fit the room you have in mind?
The Solara measures 35" x 37" x 63". The XEN measures 39" x 41" x 77".
That makes the Solara 4 inches narrower, 4 inches shallower and 14 inches shorter. In a spare bedroom, an office corner or an apartment, those inches decide where a cabin can go.
The lower cabin is on purpose. The Solara is built for seated sessions, keeping the warmth closer to your body instead of heating empty headroom. With about a third less cabin space than the XEN, there is less air to warm before you start to sweat.
It still heats up to 158°F, practically the same top heat as the XEN's 160°F, adjustable from 77°F, and assembles in under 30 minutes with no tools.

Questions
Solara vs XEN: what buyers ask
Is the SaunaBox Solara cheaper than the VITAL+ XEN?
Yes. The Solara is today on saunabox.com and the XEN Full Spectrum Infrared Sauna Standard was $3,095 (was $3,795) on VITAL+'s US store. That is £3,095 less for the Solara.
Which one gets hotter?
Practically the same. The Solara heats up to 158°F and the XEN lists up to 160°F, both adjustable from 77°F. The Solara has about a third less cabin space to heat.
Do both have red light therapy?
Yes. Both use 660nm red and 850nm near infrared light. The XEN mounts its panel on an extendable robotic arm. The Solara's panel uses a swivel design so you can change its position.
Which one has more independent safety testing?
The Solara's red light is made in an FDA-registered facility, its ultra-low EMF is certified by Intertek (IEC 62233), and Intertek certified it free of toxic heavy metals and phthalates under California Prop 65. VITAL+ lists ETL, CTI and CE certification and REACH and RoHS compliance for the XEN, and does not publish an EMF test standard, heavy metals testing or an FDA-registered facility on its product page.
What warranty comes with each sauna?
The Solara comes with a 2-Year warranty. The XEN's standard warranty is 1 year, with a +1 year extension for $145 or +2 years for $195 on the VITAL+ US store.
Which one fits a smaller room?
The Solara. It measures 35" x 37" x 63" (W x D x H). The XEN measures 39" x 41" x 77".
Do I need an electrician?
Neither lists one as required. The Solara runs on 110V at 1600W and plugs into a standard home outlet. The XEN runs on 110V at 1700W from a standard 15A household outlet.
Can I use HSA or FSA funds?
SaunaBox is a TrueMed partner, so the Solara may be eligible through TrueMed. VITAL+ does not publish HSA or FSA eligibility on the XEN product page.
