Harvia Cinder & Kaski Cube View: What Buyers Know in 2026

Harvia Cinder & Kaski Cube View: What Buyers Know in 2026

Harvia says it has more than ten product launches planned for the fourth quarter of 2026 and early 2027. Its Q3 presentation showed four examples: the Kaski Cube View cabin, the lower-priced Cinder touch control, MyHarvia 2 for Apple Watch, and a Water Reflection finish for the EOS Mythos heater.

They are not all at the same stage. Apple Watch support is already documented in MyHarvia 2, and EOS lists US model numbers for the Water Reflection finish. Kaski Cube View and Cinder are the two genuine previews that could change a home buyer's quote.

Harvia has not published consumer prices, complete specifications, North American certifications, or firm sale dates for Kaski Cube View and Cinder. If you are buying today, the current Harvia range is still the range you can compare and quote. If you are planning a purchase for early 2027, those two are worth watching before you commit.

The short version

• Harvia completed development on more than ten products during Q3 2026
• Launches are planned for Q4 2026 and early 2027
• Kaski Cube View and Cinder are the two previews most likely to affect home buyers
• No public price, order date, manual, or complete regional specification is available for either one
• MyHarvia 2 already supports Apple Watch, and EOS already lists US Water Reflection variants
• Harvia says its Finnish heater factory is shipping normally again after Q2 delays
• Some North American retail partners have started holding small sauna inventories, but Harvia did not name the stores or models

The four products Harvia has named

Product	What Harvia has disclosed	What buyers still need
Kaski Cube View	A pod-style sauna cabin with a full glass front and door, aimed at Continental Europe and North America	Dimensions, construction details, included heater, electrical requirements, price, certification, and delivery date
Harvia Cinder	A new touch control built on the Fenix platform and positioned below Fenix on price	Hardware packages, compatible heaters, safety-device requirements, app features, regional price, and release date
MyHarvia 2 for Apple Watch	Released Watch app support, including remote monitoring and start, with the same visual interface used on the Fenix panel and phone app	Confirmation that the control package in your quote supports the required Control license and safety device
EOS Mythos Water Reflection	A rippled steel finish with published US variants for the S35 at 7.5 and 9 kW and the S45 at 12 and 15 kW	Dealer stock, finish surcharge, lead time, and the complete control package

Harvia's investor presentation calls these selected examples from more than ten innovations. That means the rest of the pipeline is still undisclosed. Treat the slide as a pipeline snapshot, not a complete 2027 catalog or proof that all four products share one launch date.

Cinder is the announcement that could change a quote

The current Fenix platform is Harvia's full-touch, connected control system. It adds built-in Wi-Fi, over-the-air updates, heating profiles, timers, and remote features through MyHarvia 2. Harvia's support guide separates free Core functions from Control functions and lists a one-time EUR 99 Control license after the trial on Core-equipped products. That euro price is not a US hardware price, and some upgrade packages include Control.

Cinder matters because Harvia described it on the investor call as a lower-price entry into the full-touch category. A less expensive Fenix-based control could narrow the gap between a heater with basic built-in dials and a complete connected package.

But do not remove Fenix from a quote based on that possibility. We still need to know what Cinder leaves out, which power units and heaters it supports, whether remote start requires the same safety equipment, and whether the app license is included. A cheaper panel can still produce a higher system price if the contactor, safety device, or app tier is separate.

If you are buying a connected control before Cinder launches, ask the dealer to list every part and license on separate lines. Our Harvia brand page tracks the current Fenix package and the regional caveats.

Kaski Cube View could fill a real gap

Kaski Cube View is the most substantial new physical product Harvia showed. The company describes it as a pod-style cabin with a full glass front wall and door for Continental Europe and North America.

That puts it in a busy part of the outdoor market. Buyers can already choose among glass-front cubes, pods, barrels, and insulated cabins from several brands. Harvia's advantage is the chance to pair the room, heater, controls, and dealer support under one company. The unanswered question is whether the cabin itself is strong enough to justify the package price.

Before comparing it with another outdoor sauna, we need the wall assembly, roof build, glass specification, floor, ventilation plan, heater size, and included accessories. Full glass looks good, but it increases heat loss and can change the heater requirement. A headline seat count and a product rendering are not enough to size the circuit or judge cold-weather performance.

If your outdoor sauna purchase is months away, waiting for the Kaski Cube View specification sheet is reasonable. If you need a sauna this winter, there is no confirmed ship date to plan around. Compare current cabins on their delivered price, insulation, heater package, warranty, and local service instead.

Apple Watch control already has published requirements

MyHarvia 2 for Apple Watch is a convenience feature, not a reason by itself to replace a working controller. Harvia's current Fenix guide says the watch can monitor and remotely start the heater, and that the interface matches the Fenix panel and phone app. The US App Store version history shows Watch app support in MyHarvia 2 version 2.0.23, released August 20, 2026. A separate watch data plan is required when the paired iPhone is not available.

Remote start still requires the paid MyHarvia Control tier and a compatible safety device. Harvia says new Core-equipped products include a three-month Control trial, after which its euro-denominated guide lists a one-time EUR 99 lifetime license. A home installation uses the included door sensor unless the heater has an integrated safety device. Professional installations require Harvia's SFE safety device.

The open buyer question is the exact package in each market. Do not assume that every Wi-Fi-enabled Harvia heater includes the same control, license, or safety hardware. Ask the dealer to name the control model and every required part in writing.

Water Reflection changes the finish, not the heater category

EOS already lists Water Reflection variants on its US Mythos page. The S35 comes in 7.5 and 9 kW versions, while the larger S45 comes in 12 and 15 kW versions. The new part is the rippled steel surface, not a new heat system or a new room-size class.

That distinction matters when a dealer presents it as a new model. Compare the Water Reflection version with the same-output Mythos in another finish. Ask for the finish surcharge, the included controls and stones, and the delivery date. Do not pay more because the Q3 presentation calls it an innovation if the only difference in your quote is the exterior surface.

Harvia's supply position is improving

The product news arrived with a strong quarter. Harvia reported Q3 revenue of EUR 53.9 million, up 17 percent from a year earlier. Heating equipment grew 20.2 percent, and North American revenue grew 18.1 percent. About EUR 4 million of Q3 sales came from heater deliveries that had slipped from Q2 during a large IT and process change at the Muurame factory in Finland.

Harvia says delivery capability returned to normal during Q3. Its West Virginia factory expansion was also nearly complete at the end of September, with completion planned during Q4.

That does not guarantee that a particular heater or cabin is in stock. It does make the Q2 factory disruption less useful as a reason for an open-ended lead time. If a dealer still quotes a long wait, ask whether the delay is at Harvia, the distributor, or the dealer.

Harvia also said on its investor call that some North American retail partners have begun holding small inventories instead of relying entirely on drop shipping. The company did not identify the stores, warehouses, or models. Local pickup could reduce delivery time and damage exposure, but only when the exact boxed model is physically in stock.

Should you wait?

Wait for more information if:

• You want a modern glass-front outdoor cabin and will not install until 2027
• You want a touch controller but think the current Fenix package is too expensive

Buy from the current range if:

• Your electrician and installer are ready now
• A dealer can quote the complete heater, control, safety device, stones, freight, and warranty path in writing
• You need a proven model with available manuals and replacement parts

The sensible move is not to wait for ten unnamed products. It is to wait only when one of the four named products solves a specific problem in your build.
