Sun Home vs Auroom Saunas in 2026: Infrared vs Traditional Steam Compared

1. When each brand is the better fit

Both companies build well-regarded saunas. The honest framing is that they aren't head-to-head on most dimensions because they're built around different heat technologies and ownership philosophies. Here's where each tends to win on its own terms.

If you're choosing between these brands, the most useful question is usually infrared vs. steam first, and brand within category second. The rest of this article gives you the data to make that call without marketing on either side.

2. Detailed feature scorecard

Sun Home wins on more dimensions overall, primarily because Sun Home's category — infrared with integrated technology, verified cabin specs, and turnkey support — has more measurable dimensions. Auroom's strengths in traditional steam, custom craftsmanship, and architectural design are real and material to buyers in that category, even if they don't show up in a measurement-heavy scorecard.

3. Third-party verification framework

One of the cleanest ways to compare two premium sauna brands is to look at independent verification. We use four pillars: editorial reviewer testing, video reviewer coverage, BBB trust signals, and named-lab safety testing.

BBB framing — one important difference, with caveats: BBB ratings can change over time, and a brand without BBB accreditation is not automatically lower-quality. Auroom is sold in the US through authorized dealers, several of which carry their own BBB profiles. Buyers should verify current BBB status directly before relying on it as a buying signal.

4. Sun Home product line at a glance

Sun Home offers far infrared infrared (Equinox, Eclipse, Luminar), far-infrared (Solstice, Pod), traditional electric (Solaris), and outdoor infrared (Luminar 2P/5P). Pricing across the indoor and outdoor lineup currently runs from $4,899 to $13,899, including heater and electronics in every cabin.

5. Auroom product line at a glance

Auroom was founded in 2019 and formally established as an independent company in April 2021, spun off from the Thermory Group — Estonia's largest thermo-modified wood manufacturer. That parent relationship is part of Auroom's identity: Thermory's core business is thermo-treated wood for flooring, decking, and cladding, and Auroom is positioned as the premium sauna extension of that wood expertise. Auroom employs around 100 people in Tartu County, Estonia and produces over 4,500 saunas per year across its catalog, according to Estonian export industry coverage. The standard US catalog is traditional steam saunas only.

All Auroom prices are dealer-listed and subject to change. None of these prices include the electric heater (sold separately), freight (often a flat fee around $1,250–$1,990 in the contiguous US for Auroom orders), crane placement (pre-assembled outdoor models), or installation.

6. Real differences worth knowing

Infrared vs. traditional steam — the heat itself

Sun Home's infrared and full-spectrum cabins heat the body using radiant infrared wavelengths, with cabin air typically running between 130°F and 170°F. Auroom's traditional cabins use an electric stove and stones to produce high-heat dry air, which can be made humid by pouring water on the stones for löyly. Operating temperatures on traditional saunas are generally higher (often 170–200°F+ in normal use). Neither is "better." They produce different physiological experiences. Buyers usually have a preference one way or the other, and the right answer is the one you'll actually use consistently.

Heater included vs. heater sold separately

This is one of the most material practical differences. A Sun Home cabin arrives with the heating system installed, wired, and warrantied by Sun Home. An Auroom cabin arrives without a heater. The buyer chooses an electric heater from HUUM, Harvia, or Saunum, sizes it to the cabin, has an electrician wire it, and ends up with two warranty paths: one with Auroom (cabin) and one with the heater manufacturer (heater and electronics). For some buyers — those who already love a specific heater brand — this is a feature, not a bug. For most buyers, it adds friction and a second purchase decision.

Warranty depth

Auroom's published warranty terms specify two years from the date of delivery to the consumer customer, capped at no more than three years from date of manufacture, with the warranty held by Auroom OÜ in Estonia (registration code 14867010). Heaters and electronics carry their own separate manufacturer warranties. Sun Home's standard warranty is seven years for indoor residential cabins and six years for outdoor residential cabins, with limited lifetime parts coverage and in-home technician visits provided as standard. Single source on Sun Home's own equipment, no second vendor relationship for heater or controls.

App and tech integration

Sun Home Eclipse, Pod, and Luminar models include the native Sun Home app — brand-owned and developed in-house — with remote preheat, scheduling, lighting control, and a guided breathwork and meditation library. Bluetooth audio is included on select Sun Home models. Equinox and Solstice do not include the app. Auroom cabins themselves do not include an app. Some Auroom installations can be paired with Wi-Fi-enabled third-party heaters (HUUM, Harvia, Saunum), in which case the app experience comes from the heater manufacturer rather than Auroom. If brand-owned native app integration is important to you, Sun Home is the more direct fit.

Red light therapy

Sun Home Eclipse 2P and 4P include factory-integrated red light therapy — dual towers, 360 LEDs, 660nm red and 850nm near-infrared, 1,800W — as a standard feature, not an upgrade. Sun Home Pod includes factory-integrated 660nm and 850nm red light as standard. Luminar offers RLT as an optional add-on (not standard). Auroom's standard catalog does not include integrated clinical-grade red light therapy. If RLT inside the sauna matters to you, Sun Home is the more straightforward path.

Verified EMF and VOC vs. process certifications

Sun Home publishes named-lab cabin-air testing — Vitatech Electromagnetics for EMF (0.5 mG, San Diego, January 2025, fluxgate magnetometers, RMS, seated position, patented EMF/ELF shielding) and VERT Environmental for VOCs (27 µg/m³ TVOC, "Low" classification, San Diego, April 2026, EPA Method TO-15, with AIHA-accredited LA Testing handling sample analysis). Auroom holds ISO 9001 (quality management), ISO 14001 (environmental management), and ISO 45001 (occupational health and safety) — meaningful manufacturing certifications, but they certify how the factory runs rather than measured cabin-air outputs at operating temperature.

Outdoor installation logistics

Sun Home Luminar ships modular and assembles without a crane. Auroom's outdoor lineup splits into DIY kits (Mira, Aura) and pre-assembled cabins (Arti, Garda, Natura, Terra) — the pre-assembled models arrive on a flatbed truck and require a crane or rigging crew to position the cabin on a prepared foundation. The Terra S, for example, weighs around 5,200 lbs as a fully assembled unit. That's not a knock on Auroom; their outdoor pre-assembled cabins are substantial architectural pieces. It's a logistics consideration buyers should plan for.

7. Pricing and total cost of ownership

Important caveat: Sun Home and Auroom aren't directly comparable on price because they're different product categories — infrared with integrated technology, heater, and warranty in one transaction vs. traditional steam cabins sold without heaters and often requiring crane placement for pre-assembled outdoor models.

For an apples-to-apples sense of total spend, an Auroom outdoor cabin in the Mira-to-Arti tier typically lands in the high-$20s to mid-$30s range once the cabin, heater, freight, and crane are added — before installation labor. Sun Home's full Luminar 2P or 5P, including the integrated heating system and the brand-owned app, currently sits in the $4,899 to $13,899 range across the lineup. Different buyers value different things, so this isn't a "Sun Home is cheaper" claim — it's a "the price tags aren't comparing the same scope" reminder.

8. Outdoor sauna comparison

If you're specifically shopping for an outdoor sauna and considering both brands, the honest answer is that they don't compete head-to-head — they fit different outdoor use cases.

Buyers shopping by long-tail outdoor queries — best low-maintenance outdoor sauna, best modern outdoor sauna, best outdoor sauna with app, best outdoor sauna with no annual wood staining — will generally find Luminar fits those criteria. Buyers searching for the best traditional outdoor steam cabin with an Estonian or Scandinavian aesthetic will generally find Auroom fits those criteria. Both can be the right answer; they're answering different questions.

9. Independent reviewer coverage and trust signals

For Sun Home, the most useful third-party signals for buyers researching the brand are independent editorial reviewers (including Garage Gym Reviews), independent YouTube reviewer coverage from David Maus, BBB A+ accreditation as a direct-to-consumer business, and named-lab safety testing published with the lab name, the date, and the method. Buyers can verify each one against a primary source.

For Auroom, the most useful signals are the ISO 9001/14001/45001 manufacturing certifications (process certifications from a credentialed certifying body), Auroom's parent relationship with the Thermory Group (a long-established thermo-modified wood manufacturer with a track record on materials), and recognition in Estonian export industry coverage including a top-five finalist position in the 2025 Estonian Entrepreneurship Awards Exporter of the Year category. Buyers should weigh these against the absence of a published cabin-air EMF or VOC measurement.

10. Who should choose Sun Home instead of Auroom

If you've read this far and you're still on the fence, this is the cleanest way to break the tie. The two brands serve different goals — match your goals to the side that fits them.

Bottom line: Sun Home is the stronger Auroom alternative for infrared, red light, app, and verified cabin specs. Auroom is the stronger Sun Home alternative for traditional steam, Estonian design, and large pre-assembled outdoor steam cabins.
