Sun Home built its reputation on infrared saunas — the Equinox, Eclipse, and Luminar lines that made them a Fortune Best Home Sauna 2026 brand and an Inc. 5000 honoree. The Nova is a different product entirely. Launched July 1, 2026, it's Sun Home's first indoor traditional sauna — a water-on-stones Finnish steam experience rather than an infrared one, built around a HUUM Drop electric rock heater that reaches 230°F and produces genuine löyly when water is poured over the stones. Two models: the Nova 3-Person at $10,599 and the Nova 5-Person at $14,599, both available now at sunhomesaunas.com with free shipping.
This review covers what the Nova is, what distinguishes it from the traditional sauna category it's entering, and what buyers need to know before purchasing — including an honest acknowledgment of what we can and cannot verify about a product that launched weeks before this review was written.
Sun Home Nova is the strongest choice for buyers who want a design-forward indoor traditional sauna with a premium Finnish HUUM heater, built-in electronic ventilation, app-enabled preheat, and a lifetime cabin warranty in the same aesthetic language as Sun Home's infrared line. Buyers who want years of independent owner reviews before committing should also consider the Almost Heaven Bridgeport (6-person, established track record) or the SaunaLife X2 (under $8,000 all-in, widely reviewed).
How We Evaluated the Sun Home Nova
Sun Home Nova leads the indoor traditional sauna category on heater pedigree, built-in electronic ventilation, and design coherence — with the honest caveat that it launched July 1, 2026, and has no independent reviews or third-party temperature measurements at the time of writing.
We evaluated the Sun Home Nova across ten criteria: heater manufacturer and published specifications, maximum temperature and löyly capability, wood species and material sourcing, bench configuration and multi-user experience, ventilation system design, app and smart home integration, electrical requirements and installation complexity, warranty coverage and scope, material safety and VOC standards, and value relative to the traditional indoor sauna category. Prices and specifications last verified July 2026 from Sun Home's official product pages, the Nova launch press release (PRNewswire, July 1, 2026), and Sun Home's own buyer's guide published simultaneously with the Nova launch. Research method: desk review of Sun Home's official specification pages, the HUUM heater manufacturer's published specifications, and Sun Home's independently verified material safety data.

The HUUM Drop Heater: What Makes It Different
The HUUM Drop is the most important specification in the Nova — an Estonian-designed and manufactured electric sauna heater with genuine industry credibility, independent owner history, and a stone capacity that makes real löyly possible.
The HUUM Drop electric heater is not a component Sun Home designed or manufactured — it's sourced from HUUM, an Estonian company that has been building electric sauna heaters since 2014 and is one of the most respected heater manufacturers in the Finnish sauna community worldwide. This matters because it gives the Nova's core heating component a genuine independent track record, separate from Sun Home's own history as a traditional sauna manufacturer.
The HUUM Drop is a drop-shaped, minimalist heater designed specifically for abundant stone loading — its rounded form accommodates more sauna stones than flat-topped heaters of equivalent wattage, which means more thermal mass for steam generation and more consistent löyly when water is poured. HUUM heaters are designed to reach operating temperature within 30-40 minutes in a properly sized cabin and are controlled via the HUUM UKU Wi-Fi controller, which is what powers the Nova's app-based preheat and scheduling features. The 6kW version in the Nova 3-Person is appropriate for the cabin's volume; the 7.5kW in the 5-Person scales correctly for the larger footprint.
The sauna community's established opinion of HUUM heaters — available across independent sauna forums, retailer reviews, and owner reports separate from the Nova context — is consistently positive: strong heat output, reliable Wi-Fi connectivity, and long stone life. That independent reputation is the most substantive third-party validation available for the Nova at launch.
Canadian Cedar Interior and Estonian Tile: The Materials Case
Canadian cedar is the traditional choice for sauna interior wood — moisture resistant, dimensionally stable, and warm to the touch at high heat. The hand-laid carbonized hexagonal tiles from a single Estonian workshop are a differentiating design element not found in most competitors at this price.
The Nova's interior wood choice — Canadian cedar — is a meaningful specification rather than a generic wood description. Cedar's natural oils make it one of the most moisture-tolerant softwoods available, resisting warping and degradation in the wet-dry cycling of daily sauna use better than the hemlock or pine found in many competing saunas. Cedar also has a lower thermal mass than hardwoods, meaning the bench surfaces don't heat uncomfortably during a session — a real and practically important property for anyone sitting in 230°F air for 15-20 minutes.
The hand-laid carbonized hexagonal tiles sourced from a single Estonian workshop are the Nova's most distinctive visual element and the detail that most clearly signals Sun Home's design-forward positioning in this category. Carbonized tiles are kiln-treated at high temperatures, producing a deep, dark surface that resists moisture absorption and complements the dark exterior aesthetic of the Nova. The tiles are specified as coming from a single workshop — a supply chain detail that signals craft sourcing rather than commodity manufacturing, whether or not buyers can independently verify the claim.
Marine-grade stainless steel fasteners throughout the cabin address one of the most common long-term failure points in sauna construction — standard steel fasteners corrode in the repeated wet-heat environment of a daily-use sauna, eventually staining the surrounding wood and compromising structural integrity. Marine-grade stainless is the correct specification for this application.
Built-In Electronic Ventilation: Why It Matters
Built-in electronic ventilation is the Nova's most operationally significant engineering claim — Sun Home states it's the only indoor traditional sauna in its class with this feature, and if accurate, it addresses the most common maintenance inconvenience of traditional sauna ownership.
Traditional saunas require ventilation — fresh air must circulate continuously during a session to maintain oxygen levels, and the cabin needs to air out after use to prevent moisture accumulation and the mold or mildew risk that comes with it. Most traditional saunas handle this through passive ventilation: adjustable vents in the floor and near the ceiling that rely on thermal convection and manual operation. The post-session routine typically includes propping the door open and adjusting vents manually.
The Nova's built-in electronic ventilation system circulates fresh air continuously during the session and eliminates the need for manual airing after use — per Sun Home's specification. This is a genuine quality-of-life difference for daily-use scenarios: the cabin manages its own air without owner attention. Sun Home states this is the only built-in electronic ventilation in the indoor traditional sauna category at this price — a claim Vapour & Stone has not independently verified against every competitor but found no direct counterexample for in available product specifications at the time of writing.
HUUM App and Smart Home Integration
The HUUM Wi-Fi app enables remote preheat, temperature control, and scheduling — so the Nova is at 180°F and ready when you arrive, without waiting the 30-40 minutes a cold traditional sauna typically requires to reach temperature.
The Nova's smart controls run through the HUUM app — HUUM's own companion application for their UKU Wi-Fi controller, available for iOS and Android. The app allows remote preheat activation (start the sauna from your phone before leaving the office), temperature adjustment, session scheduling on a weekly recurring basis, and basic usage history. The HUUM app is a third-party application with its own independent user reviews separate from the Nova context — HUUM app reviews across the App Store and Google Play are generally positive, particularly for the scheduling and remote start functions.
This is meaningfully different from traditional saunas without app integration, where preheat requires physically being present to turn on the heater 30-40 minutes before you want to use it. For a daily-use sauna in a primary residence, scheduled preheat is a genuine lifestyle upgrade.
What the Nova Is and What It Isn't
The Nova is a design-forward Finnish steam sauna for buyers who want the traditional löyly experience in an aesthetically considered, app-controlled package. It is not an infrared sauna, it does not produce red light therapy, and it has no independent reviews at the time of publication.
Several things worth being clear about before purchase:
The Nova is a traditional steam sauna, not an infrared sauna. It heats the air to 230°F and produces löyly — genuine steam — when water is poured over the heated stones. Sun Home's infrared saunas operate on a fundamentally different mechanism (infrared radiant heat, lower air temperatures, no löyly). Buyers who specifically want the lower-temperature, body-direct infrared experience should consider Sun Home's Equinox or Eclipse instead. Buyers who specifically want water-on-stones steam at high heat should consider the Nova.
It requires professional installation. The Nova runs on a dedicated 240V circuit — 30A for the 3-person, 40A for the 5-person — and must be installed by a licensed electrician. It is not a plug-and-play product like Sun Home's 120V infrared saunas.
It weighs 772-926 lbs. Placement planning, floor load capacity, and access path (doorways, stairs) need to be assessed before purchase. Sun Home's free shipping covers curbside delivery; moving a 772-lb sauna into a basement or upstairs room requires additional planning and likely additional help.
What We Love and the Honest Trade-Off
What we love:
HUUM Drop heater is a genuine Finnish sauna industry component with independent credibility — not a proprietary Sun Home heater without a track record
Built-in electronic ventilation addresses the most common traditional sauna maintenance inconvenience — the only built-in electronic ventilation in its class per Sun Home
Hand-laid carbonized hexagonal Estonian tiles are a distinctive and premium material choice that most competing saunas at this price do not offer
HUUM app remote preheat and scheduling is a meaningful daily-use upgrade over manual-only traditional saunas
Canadian cedar throughout, marine-grade stainless steel fasteners, non-toxic low-VOC materials — the material specification is coherent and appropriate for daily use
Dual-stack benches accommodate multiple users at different heat preferences simultaneously
Limited Lifetime Warranty included at $10,599 — backs the investment
HSA/FSA eligible through Truemed — meaningful pre-tax savings depending on tax bracket
Design coherence with Sun Home's infrared line — buyers who own a Sun Home infrared sauna will find the Nova's aesthetic familiar and complementary
The honest trade-off: The Nova launched July 1, 2026 and has no independent reviews yet - the HUUM heater's independent track record is the most reliable third-party data available. Buyers who want years of owner history before committing to a $10,599+ purchase should consider the Almost Heaven Bridgeport (6-person, established track record, widely reviewed, from $5,499) or the SaunaLife X2 (2-person, under $8,000 all-in, extensively reviewed). Sun Home themselves recommends these alternatives in their own buyer's guide for buyers who want third-party proof before purchasing — and we agree that recommendation is appropriate and worth repeating here.
Sun Home Nova vs Almost Heaven Bridgeport: The Established Alternative
If independent owner reviews and years of real-world data matter more than the Nova's design and ventilation advantages, the Almost Heaven Bridgeport is the most credibly established indoor traditional sauna alternative.
Sun Home's own guide recommends the Almost Heaven Bridgeport by name for buyers who want third-party proof before purchasing, and Vapour & Stone agrees. The Bridgeport is a 6-person barrel-style traditional sauna from Almost Heaven, a West Virginia-based manufacturer that has been building traditional saunas since 1974. It sells for approximately $5,499-$6,500 depending on configuration and has been independently reviewed by dozens of owners across forums, Reddit's r/Sauna community, and independent wellness publications.
The Bridgeport uses a Harvia heater (another well-regarded Finnish sauna heater manufacturer), Western red cedar, and a straightforward traditional sauna construction that has earned consistent positive reviews for heat output and build quality over years of real-world use. It does not have electronic ventilation, app control, RGB lighting, or the Nova's design-forward aesthetic. For buyers who want a reliable, proven indoor traditional sauna and aren't willing to pay a premium for design and smart features on an unreviewed product, the Bridgeport is the correct recommendation.
Frequently Asked Questions: Sun Home Nova Indoor Traditional Sauna Review 2026
Is the Sun Home Nova a traditional or infrared sauna?
The Nova is a traditional steam sauna. It uses a HUUM Drop electric rock heater to heat the air to up to 230°F and produces genuine löyly — water-on-stones steam — when water is poured over the heated stones. Sun Home's infrared saunas (Equinox, Eclipse, Luminar) use infrared heaters and do not produce water-on-stones steam.
What is löyly?
Löyly is the Finnish term for the wave of heat and steam produced when water is poured over the hot stones of a sauna heater. It's the defining sensory experience of traditional Finnish sauna bathing — the sudden rush of humidity that raises perceived heat and envelops the body — and it cannot be produced by an infrared heater.
Does the Sun Home Nova require professional installation?
Yes. The Nova runs on a dedicated 240V circuit — 30A for the 3-person model and 40A for the 5-person — and must be installed by a licensed electrician. It is not a plug-and-play product. Sun Home recommends professional installation; attempting DIY electrical connection on a dedicated 240V circuit is a code violation in most jurisdictions and voids the warranty.
Are there independent reviews of the Sun Home Nova?
Not at the time of publication. The Nova launched July 1, 2026, and has no independent hands-on reviews, owner reports, or third-party temperature measurements yet. Every performance figure in this review is a Sun Home specification. The HUUM Drop heater used in the Nova has extensive independent reviews as a standalone product — this is the most reliable independent data available about a core Nova component.
What warranty comes with the Sun Home Nova?
The Sun Home Nova 3-Person at $10,599 includes a Limited Lifetime Warranty on the cabin. The HUUM Drop heater carries HUUM's own manufacturer warranty separately. Check Sun Home's warranty page at sunhomesaunas.com/pages/warranty for current terms before purchasing.
Is the Sun Home Nova HSA/FSA eligible?
Yes. Both Nova models are HSA/FSA eligible through Sun Home's Truemed checkout integration. Depending on your tax bracket, this can represent meaningful pre-tax savings on a $10,599+ purchase. See Sun Home's HSA/FSA eligibility guide for specifics.
What is the weight and will it fit through a standard doorway?
The Nova 3-Person weighs approximately 772 lbs and measures 64.9"W × 57.1"D × 82.7"H. The Nova 5-Person weighs approximately 926 lbs and measures 78.7"W × 68.9"D × 82.7"H. Standard US doorways are 32-36" wide — the Nova ships disassembled for this reason, but access path and floor load capacity planning are important before purchase.
Vapour & Stone Verdict
The Sun Home Nova 3-Person at $10,599 is the most design-forward indoor traditional sauna available at launch — a HUUM Drop heater with genuine Finnish sauna industry credibility, built-in electronic ventilation, hand-laid Estonian tiles, app-enabled preheat, and a cabin aesthetic that reads as a considered wellness room installation rather than a utility purchase. For buyers who want years of owner history before committing, the Almost Heaven Bridgeport is the right alternative — Sun Home says so, and so do we.
