This is a spec-sheet review, not a hands-on one. I haven't used the Nova, and I'm not going to pretend otherwise. What I can do is read what Sun Home publishes about it, check the numbers against independent heater and electrical pages, and tell you which questions the sheet leaves open. That is the angle of this Sun Home Nova sauna review: every figure carries a source marker, and the gaps are listed at the bottom.
One thing to keep in mind from the start. Sun Home makes and sells the Nova, so everything from their pages is "the maker says", not independent confirmation.
Sun Home Nova sauna review: the quick verdict
The Nova is a pricey, pre-built, Finnish style home sauna for people who want a 3-person traditional cabin with a glass front and a Wi-Fi-controlled HUUM heater, and who are ready to pay an electrician for a dedicated 240V circuit. The listed price is $12,499. If that sits inside your budget and you have a dry indoor room with the clearances it asks for, the spec sheet reads coherently.
Skip it if you want infrared heat, if you need to keep the total under about ten thousand dollars once electrical work is added, or if you want long warranty coverage on the heater and the electronics. The warranty page I read is thinner on those than the product page's headline suggests. I'd also hold off until you have asked the maker the heater-size question I raise below.
Specs and what the maker says
Here is what the two Sun Home pages list for the 3-person model, with the independent heater data alongside.
| Item | What I found |
|---|---|
| Price | $12,499, checked 2026-10-06 |
| Type | Indoor only, electric heater, water on stones |
| Heater | HUUM DROP 6kW |
| Max temperature | 230°F (maker's figure) |
| Power | 240V, dedicated 30A circuit, hardwired |
| Exterior size | 64.9in W x 57.1in D x 82.7in H |
| Interior size | 59.1in W x 53.5in D x 77.1in H |
| Weight | 772 lbs |
| Interior wood | Canadian cedar |
| Back wall | Hand-laid carbonized hexagonal tile |
| Front | Black privacy glass, described as thermal-optimized |
| Benches | Dual-stack |
| Fasteners | Marine-grade stainless steel |
| Lighting | Warm LEDs behind the tile, RGB under the benches |
| Control | Wi-Fi through the HUUM app (2.4GHz) |
| Included | Cabin, heater and controller, sauna stones |
| Sold separately | Bucket and ladle ($85), care set ($120) |
The heater is a known quantity. HUUM's DROP 6kW is listed by a retailer as a 6 kW unit that accepts single-phase 240V, holds 55 kg of stones and weighs 11 kg empty. A second listing lists the same family as reaching 230°F and needing a 30A breaker with 10 AWG wire for the 4.5 and 6 kW versions. That matches Sun Home's 30A requirement, which is reassuring, because three separate pages agree on the circuit.
The product page also shows a 5.0 star rating from 5 reviews. That is five reviews on the seller's own page, so I give it no weight.
Who the 3 person indoor traditional sauna suits
It suits a buyer who has already decided on a traditional sauna. The product page describes an electric heater with water-on-stones löyly, which is the steam-burst style people mean when they say Finnish style. If you want that and not the gentler radiant heat of infrared, read my infrared vs traditional sauna guide before you pay for the wrong format.
It also suits someone with a real indoor space. The Nova is sold for indoor installation only. A finished basement, a garage bay that is dry and conditioned, or a spare room with a hard floor are the sort of places I would expect people to consider. I haven't seen the maker list specific room types for the Nova, so treat that as my reading, not their claim.
A third group: buyers who care about the look. The tile back wall, the glass front and the two lighting systems are the design points the maker leans on. I can't judge how they look in a room from a spec sheet, and photos are always flattering, so look at the gallery images with that in mind.
Last, it fits people who want one box to arrive with the heater, controller and stones included.
Sun Home Nova price and the drawbacks I can see
The first is the price per seat. My arithmetic: $12,499 divided by 3 seats is about $4,166 per seat. The 6-person Nova lists at $16,399, which is about $2,733 per seat (16,399 divided by 6). The larger cabin costs $3,900 more (16,399 minus 12,499) and doubles the seating. If you have the room and might host, the 3-person model is the poorer value per seat. If it is only ever you and a partner, that logic doesn't help you much.
The second is the electrician bill, which sits on top. Sun Home says a licensed electrician is required for the hardwired circuit. I could not find a cost for that on any page I opened, and it depends on your panel and the distance to the room, so I won't invent one. Budget a quote before you order. Topture's guide advises talking to an electrician before purchase to confirm your panel can carry the load.
The third is the warranty. The product page says "Limited Lifetime Warranty". The warranty page, for orders from March 2, 2026, lists the Nova as limited lifetime on cabinetry, 1 year on fan and light controls, and 1 year on LED lighting. For other models the same page lists heaters alongside cabinetry; the Nova line, as I read it, doesn't name the heater. It also says the warranty covers the original purchaser only, and that improper installation or extension cords void coverage. HUUM's own terms, according to one retailer, exclude heating elements. Ask Sun Home in writing what happens if the heater fails in year two.
The fourth is heat-up time. Sun Home says about one hour of preheat. A heater review lists 60 to 90 minutes to peak temperature for the DROP as a drawback. That is normal for an electric traditional heater, but if you want a ten-minute session before work, this is the wrong tool.
The fifth is the heater-size question, which I think deserves attention. From the interior dimensions, my arithmetic: 59.1 x 53.5 x 77.1 inches is about 243,800 cubic inches, or roughly 141 cubic feet (about 4.0 cubic metres). Haven of Heat lists the DROP 6 as covering 177 to 353 cubic feet, and the Finnmark page lists 5 to 9 cubic metres. By that rough sum the Nova's interior is below the bottom of both ranges. I can't tell what that means in practice. Makers calculate volume in different ways, and the ranges are retailer guidance, not a rule from HUUM that I read directly. It is a fair question to put to Sun Home before you buy.
The sixth is the build. Two lighting systems, a Wi-Fi controller and glass are more parts that can fail, and the warranty on the electronic bits is one year. A simpler sauna with a basic controller would have fewer of them.
Prepare your space
Each point below comes from a page I opened. Where a page didn't say, I say so.
Electrical. The Nova needs a 240V, dedicated 30A circuit, hardwired. The Sun Home space guide adds that you should avoid extension cords and shared outlets, and the warranty page says extension cords or power strips void coverage. An independent guide says traditional heaters typically need dedicated hardwired 240V circuits installed by a licensed electrician to meet the National Electrical Code and local rules. Whether your house needs a permit depends on your town, and I didn't find a source, so ask your electrician.
Clearances. The Nova page lists 1 foot on the heater side for fresh-air intake, 2 feet on the exhaust side and 2 feet overhead. My arithmetic on height: 82.7 inches of cabin plus 24 inches overhead is 106.7 inches, so a ceiling of roughly 8.9 feet. If the two side clearances are on opposite sides, which the page doesn't say, add 36 inches to the 64.9 inch width for about 100.9 inches. Sun Home has a general space guide that mentions only 2 to 6 inches on the sides and back, but it says it applies to Sun Home saunas in general and doesn't isolate the Nova. The Nova page is the one I would follow, and the installation manual the maker links to is the real authority. I didn't read that manual.
Floor. Sun Home's general guide says its saunas sit on any flat, level, stable surface, with shimming for uneven ground. The assembly guide says the sauna must sit on a stable, level surface. Neither page is specific to the Nova, and neither gives a floor load rating. At 772 lbs, I would ask about that before putting it on a raised or older floor.
Room. The space guide recommends a dry, climate-controlled room with good ventilation and no excess moisture.
Delivery. The shipping page says delivery is curbside, liftgate included, and the driver doesn't bring items into your home. You are responsible for moving it indoors, and the page suggests several people. The product page says shipping is free, valued by the maker at $1,500. It also describes a two-stage delivery: the cabin arrives separately from the heater, controller and stones. Concealed damage must be reported within 5 business days of delivery. In-stock items ship within 7 business days, but I couldn't confirm whether the Nova is in stock.
Install. The product page says cabin assembly can start any time, with the electrician needed once all components arrive. I couldn't find assembly time or the number of people needed. The general space guide says to have at least 2 people.
How it compares
Against infrared: an infrared cabin runs on lower-temperature radiant heat, usually on a smaller circuit, and doesn't make steam bursts. I don't compare prices here because I haven't verified a matching infrared model. My infrared vs traditional sauna guide covers the format question, and my sauna cost guide puts purchase, install and electricity in one table.
Against an outdoor sauna: the Nova is indoor only. If you want a backyard barrel or cabin, you need another product, and my best outdoor sauna page covers eight of them. An outdoor build has weather and foundation questions that the Nova avoids, but it needs the same sort of dedicated electrical supply.
Against its own sibling: the 6-person Nova uses a HUUM DROP 7.5kW heater and needs a dedicated 40A circuit, hardwired, at 240V. It measures 78.7in W x 68.9in D x 82.7in H and weighs 926 lbs. Independent guidance lists a 40A breaker and 8 AWG wire for the 7.5 kW DROP. So the larger cabin may mean a bigger electrical job than the 3-person one, not just a bigger price. Sun Home also sells other lines, such as Eclipse, Luminar, Equinox and Solstice, which its warranty page lists. I didn't open their product pages, so I can't compare specs.
Frequently asked questions
What electrical setup does the Sun Home Nova need? The maker says the 3-person model needs a dedicated 30 amp circuit at 240V, hardwired, installed by a licensed electrician before delivery. Independent sources list a 30A breaker and 10 AWG wire for the HUUM DROP 6kW. Your electrician should work from the manufacturer's manual for your exact unit.
How hot does the Nova get? The maker lists a maximum temperature of 230°F. HUUM's DROP heater family is listed at the same figure by a retailer review. I don't have a measured temperature for the cabin, since I haven't tested it.
Is shipping really free? The product page says "Free Shipping" and values it at $1,500. The shipping policy says delivery is curbside only, with liftgate service, and that you handle getting it indoors. So free means to the curb, not into your sauna room.
Is the Nova an infrared sauna? No. The product page describes an electric heater with water on stones, which is a traditional sauna. If you prefer infrared, this is the wrong model.
What does the warranty cover? For orders from March 2, 2026, the warranty page lists limited lifetime on cabinetry, 1 year on fan and light controls, and 1 year on LED lighting for the Nova. It is for the original purchaser only. Get the full terms before buying, because the product page summary is shorter than the policy.
Is the Sun Home Nova worth it? That depends on what you compare it with, and I can't answer from use because I haven't tested it. What I can show from the pages: the 3-person Nova is listed at $12,499, which is about $4,166 per seat (my arithmetic), and you add a dedicated 30A hardwired circuit from a licensed electrician. If you want a Finnish style home sauna indoors and the room has the clearances the page asks for, the specs read coherently. If infrared is what you want, or the budget stops near $10,000 once electrical work is added, it is the wrong model.
What I could not verify
- The cost of the electrician and any permit. No page I opened gives one, and it varies with your home.
- How Sun Home sized the HUUM DROP 6kW to the cabin's interior volume, and whether the figures I used match their method.
- Whether the warranty covers the heater on the Nova, since the Nova line on the warranty page doesn't name it.
- Which side is the heater side and which is the exhaust side, and whether they are opposite.
- Assembly time, tools and people needed, and floor load. The Nova installation manual and owner's manual are linked from the assembly guide, and I didn't read them.
- Current stock and lead time for the Nova.
- The tile and glass quality, the build quality, noise, and how it performs in a room. These need a hands-on review, and I haven't done one.
- Any long-term reliability data or genuine owner reports. The five reviews on the maker's page are too few to use.
- Whether the maker's clearance rules match local codes. Ask your electrician and your building department.
- Any price other than the one shown on 2026-10-06. It can change.
What I would do
If I were buying a Nova, I'd email Sun Home three questions before paying a cent: is the DROP 6kW the right size for a 141 cubic foot interior, does the warranty cover the heater, and which sides need the 1 and 2 foot clearances. Then I'd get a written quote from an electrician for the 30A hardwired circuit and add it to the $12,499 before deciding.
If the answers are clear and the total fits, my Sun Home Nova sauna review verdict is that it looks like a sensible buy on paper: a pre-built traditional cabin with a well-known heater. If the answers are vague, I'd look at a cheaper 3 person indoor traditional sauna from another maker and spend the difference on the electrical work.
