Sun Home Solaris Sauna Review: Is a $45,399 Outdoor Sauna Worth It?

By MindReset Editorial Desk · Research-based buyer guidance

Sun Home Solaris sauna review

This research-based Sun Home Solaris sauna review examines a very different kind of home wellness purchase.

The Solaris Medium is not a flat-pack backyard sauna, an infrared cabin, or a budget way to experience heat therapy.

It is a made-to-order, factory-built outdoor traditional sauna designed for four to six people, constructed from Thermory wood, reinforced with stainless steel, fitted with expansive heat-resistant glass, and powered by a Wi-Fi-enabled HUUM traditional sauna heater.

The current listed promotional price was $45,399, reduced from $46,199, when checked on August 7, 2026.

That price immediately changes the question.

The buyer is not asking whether sauna bathing is worth $45,399.

The real question is whether Solaris provides enough architectural design, materials, weather resistance, factory assembly, space, premium presentation, and installation convenience to justify costing several times more than a conventional traditional sauna.

Quick Verdict: Is the Sun Home Solaris Worth $45,399?

For sauna performance alone, no—you do not need to spend $45,399 to experience a serious traditional sauna.

For the right luxury-property buyer, however, the Solaris becomes much easier to understand.

You are paying for a completed outdoor structure rather than just a heater and wooden room.

• Factory-built European construction
• Thermory pine exterior
• Thermory aspen interior
• Marine-grade stainless steel reinforcement
• Large panoramic glass frontage
• High-density insulation
• Traditional HUUM rock-heater system
• Wi-Fi heater control
• Published temperatures above 220°F
• Double-level seating
• Space for approximately four to six people
• A finished architectural design intended to remain outdoors

The Solaris is therefore less comparable to a $6,000 sauna kit than to installing a purpose-built luxury wellness structure beside a premium home, pool, resort, or guest property.

Our verdict: The Solaris makes sense when design, permanent outdoor installation, traditional high heat, premium materials, and avoiding on-site cabin construction matter more than price efficiency.

It is difficult to justify when your priority is simply getting an excellent sauna session for the least money.

Sun Home Solaris Buyer Decision Table

Sun Home Solaris Pros and Cons

Who Should Buy the Solaris Medium?

• You own a property where a permanent outdoor sauna makes sense.
• You want traditional sauna heat rather than infrared.
• You regularly sauna with a partner, family, or guests.
• You consider exterior architecture part of the purchase.
• You want panoramic glass facing a garden, forest, mountain, pool, or waterfront view.
• You do not want a flat-pack cabin assembled in your backyard.
• You value thermally modified outdoor wood.
• You want Wi-Fi heater controls.
• You are prepared to organize electrical and site work before delivery.
• You are comfortable treating the purchase as effectively final.
• The $45,399 purchase price represents an acceptable luxury-property upgrade rather than a major financial stretch.

Who Should Avoid It?

• You simply want the best sauna experience per dollar.
• You mostly sauna alone.
• You need an indoor unit.
• You rent your home.
• You may relocate in the near future.
• Your site has difficult crane, forklift, driveway, or freight access.
• You cannot install a dedicated 240V electrical circuit.
• You want infrared or red-light therapy integrated into the same cabin.
• You expect easy returns after seeing the sauna in person.
• You are buying mainly because of broad health or longevity claims.

Sun Home Solaris Medium Specifications

Important specification note: Sun Home currently publishes conflicting figures for cabin volume. One section of the product page lists 287 cubic feet, while another lists 224 cubic feet. Buyers should request the final technical specification for their exact configuration before electrical or site work begins.

What Are You Actually Paying $45,399 For?

This is the most important question in the entire review.

You are not paying $45,399 because the human body somehow recognizes expensive sauna heat.

A properly designed traditional sauna costing far less can also provide high temperatures, heated stones, wooden benches, and a traditional sauna environment.

The Solaris premium is primarily paying for:

• Architectural exterior design
• Custom finish options
• European factory construction
• More than 100 hours of manufacturer-stated assembly work
• Premium thermally modified timber
• Large engineered glazing
• Outdoor weather resistance
• Structural reinforcement
• High-density insulation
• A premium HUUM heater system
• Factory quality control
• Delivery of a substantially completed outdoor structure

That distinction matters.

If you want heat, buy a sauna.

If you want a premium architectural object that also happens to be a serious traditional sauna, Solaris becomes much more defensible.

How Traditional Is the Solaris Sauna Experience?

The Solaris is fundamentally different from Sun Home’s infrared models.

Instead of heating the body primarily through infrared emitters at lower cabin temperatures, Solaris uses a traditional HUUM sauna heater and rock-based high-temperature environment.

Sun Home publishes temperatures above 220°F, although actual heat-up time and maximum stable temperature depend on outdoor temperature, wind exposure, heater settings, installation, and door use.

For buyers who specifically want a Finnish-style traditional sauna experience rather than infrared, that distinction is meaningful.

How Good Is the HUUM Heater?

HUUM is an established European sauna-heater manufacturer known for large stone capacity and modern control systems.

The current Solaris technical sheet identifies a 6kW Wi-Fi-enabled HUUM heater.

Remote control is particularly useful in an outdoor sauna because the cabin can be heated before you walk outside for a session.

However, remote start does not remove normal sauna safety requirements. The heater area should always be checked before activation and installation must follow the heater manufacturer’s clearance and electrical requirements.

Sun Home currently advertises a five-year warranty for the HUUM heater.

How Good Are the Thermory Woods?

The Solaris exterior is built from thermally modified Thermory pine, while the interior uses Thermory aspen.

Thermal modification uses controlled heat treatment to improve dimensional stability and reduce the wood’s tendency to absorb moisture.

That makes the material particularly relevant for an outdoor sauna that repeatedly experiences:

• Rain and humidity
• Strong sunlight
• Cold weather
• High internal heat
• Repeated heating and cooling cycles

The interior aspen also provides a smoother low-resin seating surface than many inexpensive softwoods.

Premium wood still requires care. “Outdoor rated” should not be interpreted as maintenance-free.

Does All That Glass Hurt Sauna Performance?

Large glass walls are usually a compromise in traditional sauna design because glass insulates less effectively than a heavily insulated opaque wall.

Solaris addresses this with triple-layer heat-resistant glazing and insulated wall construction.

The panoramic front therefore serves two purposes:

• It gives the Solaris much of its visual appeal.
• It allows the cabin to be positioned around an outdoor view rather than feeling like an enclosed wooden box.

We could not independently verify the real-world heat-loss difference between Solaris and an equivalent sauna with less glass.

How Much Space Does the Solaris Medium Need?

The cabin itself occupies approximately 7.5 by 7.5 feet before allowing for access, electrical work, maintenance clearance, landscaping, and safe entry.

Do not design the installation around the sauna dimensions alone.

A realistic site plan should consider:

• A level load-bearing foundation
• Walkway access
• Door clearance
• Electrical conduit
• Drainage around the structure
• Snow or rain runoff
• Ventilation
• Service access
• Delivery and lifting access

At nearly 1,874 pounds before occupants, Solaris should be treated more like a small outdoor structure than patio furniture.

The Biggest Hidden Cost: Getting 1,874 Pounds Into Position

The product page currently advertises free shipping.

That does not necessarily mean free placement at the final installation site.

Sun Home’s general freight policy describes sauna deliveries as curbside service.

That is especially important with Solaris because the cabin is promoted as arriving pre-built and weighs approximately 1,874 pounds.

Depending on your property, final placement may require:

• Forklift access
• Telehandler access
• A crane or lifting contractor
• Professional riggers
• Temporary removal of fencing
• Driveway protection
• Landscape access planning

We would not place a Solaris order until Sun Home has confirmed—in writing—exactly where the included freight service ends.

What Electrical Work Does Solaris Require?

The current Sun Home support guidance says the Solaris Medium requires a dedicated 240V, 40A circuit and must be hardwired by a licensed electrician.

This work should ideally be planned before the sauna arrives.

Potential costs include:

• New breaker capacity
• Outdoor-rated cable or conduit
• Long cable runs
• Trenching
• Disconnect equipment where required
• Electrical permitting
• Labor

Documentation issue: The downloadable Solaris M technical sheet describes the unit as 240V / 6kW and uses “plug-and-play” wording, while the current Sun Home support page explicitly says Solaris M is hardwired with no plug and requires a 240V / 40A dedicated circuit.

For a $45,000 purchase, the sensible move is to request the final electrical drawing for the exact heater and sauna configuration before your electrician begins work.

How Difficult Is Installation?

The good news is that Solaris is not a conventional DIY sauna kit.

The cabin is advertised as arriving structurally pre-assembled after more than 100 hours of factory construction.

That removes one of the biggest headaches associated with large backyard saunas: assembling hundreds of wooden components, glazing, benches, trim, roof sections, and heater protection on site.

But pre-assembled does not mean zero installation.

• The site must already be prepared.
• The sauna must be transported from the delivery point.
• It must be positioned and leveled.
• Electrical work must be completed.
• Local permits may be required.
• The heater must be commissioned according to the applicable installation requirements.

What Are the Hidden Ownership Costs?

Site preparation

A suitable concrete pad, structural deck, pavers, drainage base, or engineered foundation may be required.

Electrical installation

The dedicated 240V run is not something most buyers should treat as a minor accessory expense.

Final placement

A pre-built 1,874-pound cabin may require specialist lifting or material-handling equipment.

Permitting

Local electrical, zoning, setback, HOA, or accessory-structure requirements may apply depending on the property.

Electricity

Actual operating cost depends on outdoor temperature, session temperature, warm-up time, session frequency, local electricity rates, and how effectively the cabin retains heat between heating cycles.

Wood and exterior care

Thermally modified wood is durable, but outdoor exposure still means cleaning, cosmetic aging, inspection of seals, and potentially periodic surface maintenance.

Can You Return the Solaris If You Change Your Mind?

This is one of the most important parts of the purchase: treat the Solaris as effectively final-sale.

The Solaris product page explicitly describes it as handcrafted and made-to-order.

Sun Home’s current return policy lists made-to-order traditional saunas among products that are non-refundable.

That is different from the general 30-day return policy applied to eligible unused, unopened standard sauna products.

Before paying, verify:

• Final exterior finish
• Interior finish
• Glass configuration
• Electrical specification
• Delivery access
• Exact foundation dimensions
• Local permit requirements
• Final cancellation terms

At this price level, a wrong assumption can become a very expensive mistake.

How Good Is the Warranty?

Sun Home currently lists a three-year residential limited warranty on Solaris cabinetry, including interior and exterior wood components.

The HUUM heater is advertised with separate five-year coverage.

Buyers should pay attention to labor and freight.

Sun Home’s broader warranty terms state that shipping and labor are included only during the first 90 days for covered product categories, after which the customer may be responsible for those costs.

A warranty part is much less useful if removing, shipping, reinstalling, or accessing that component costs thousands of dollars, so ask how service works for a permanently installed Solaris before purchase.

Solaris Medium vs Solaris Small

The Medium only makes sense if you will actually use the extra depth and seating capacity.

For a couple who rarely hosts sauna guests, saving roughly $9,000 and choosing Solaris Small may be the more rational luxury purchase.

Solaris Medium vs Sun Home Nova 6-Person

The price gap becomes much more revealing when Solaris is compared with Sun Home’s own indoor traditional sauna range.

This comparison makes the Solaris proposition very clear.

The extra money is primarily buying the outdoor architectural structure—not three times more sauna.

What Is Real Product Value and What Is Wellness Marketing?

The genuine Solaris advantages are easy to identify:

• Traditional high-temperature heat
• Premium HUUM heater
• Large capacity
• Outdoor-ready Thermory construction
• Extensive factory assembly
• Premium insulation
• Panoramic glazing
• Architectural appearance
• Wi-Fi temperature control
• Permanent luxury-property integration

Those are real product attributes.

The Solaris does not create special biological effects simply because it costs $45,399.

Sauna bathing has been associated with cardiovascular and wellbeing outcomes in observational research, but association should not be confused with guaranteed treatment effects.

More recent randomized evidence on passive heating has found no consistent pooled improvement across many cardiometabolic markers.

Buy Solaris because you want this sauna—not because you believe its purchase price buys stronger health outcomes than a properly designed traditional sauna costing much less.

Sauna Safety

Traditional sauna temperatures create substantial heat stress and fluid loss.

Stay hydrated, exit if you feel dizzy or unwell, and avoid combining sauna use with alcohol.

People with cardiovascular conditions, poorly controlled blood pressure, fainting history, pregnancy, heat intolerance, or relevant medication use should discuss sauna use with a qualified healthcare professional.

People with controlled high blood pressure can often tolerate sauna use, but anyone who has been advised to avoid moderate exertion should be cautious with high heat.

Final Verdict: Should You Buy the Sun Home Solaris Medium?

The Solaris Medium is an extravagant sauna purchase—but it is not an irrational product.

The distinction matters.

You can absolutely build or buy a serious traditional sauna for dramatically less than $45,399.

What is difficult to replicate cheaply is the complete Solaris package: a factory-built European outdoor structure, Thermory construction, large panoramic glazing, high-density insulation, premium traditional heater, stainless reinforcement, custom appearance, and a finished architectural design intended to become part of the property.

Buy it when: you already know you love traditional sauna bathing, have a permanent outdoor location, value architecture as much as heat performance, and can absorb the installation cost without compromising the rest of your project.

Skip it when: you primarily want the health, relaxation, or traditional sauna experience. Far less expensive models can deliver those fundamentals.

The Solaris is not the sauna you buy because you need a sauna.

It is the sauna you buy because you want this particular sauna sitting outside your home.
