Cost of Indoor Saunas: Price Breakdown
Golden Designs "Copenhagen Edition" 3-Person Traditional Steam Sauna
$6,999.00 $8,999.00
Built with Canadian Red Cedar, this traditional steam sauna turns the dream of a home spa into reality, even where space is limited.
View ProductAs far as prices go, one of the first key considerations when getting a sauna is whether to get an indoor or outdoor unit.
The price of an indoor sauna varies depending on the heating source, electrical complexity, capacity, and manufacturer.
Our collection's various indoor saunas from reliable brands range from $1,899 to $17,000.
Here's a table to put things in perspective:
| Indoor Sauna Type | Average Price Range | Capacity |
| Entry-level indoor saunas | $1,900 to $5,000 | 1–2 persons |
| Mid-range indoor sauna | $6,000 to $10,000 | 2–4 people |
| Premium indoor saunas | $10,500 to $17,000 | 4–6 people |
Although capacity isn't the only reason for higher prices, some 2-person saunas cost as much as $10,000 due to extra features and higher-end materials.
Entry-level indoor saunas
Entry-level indoor saunas have fewer heaters and simpler controls, but they're still efficient. They typically fit one person and are usually infrared saunas.
For example, models like the Dynamic "Avila" and Finnmark FD-1 Full-Spectrum infrared saunas run $1,900 and $4,680, respectively, and can accommodate 1 to 2 people.
Mid-range indoor sauna
The saunas that fall into the mid-range price bracket are usually those with up to 4-person capacity and more advanced heating technology.
Golden Designs' Forssa Edition costs up to $6,300 and is a 3-person traditional steam sauna.
Hybrid models like the Finnmark FD-5 Trinity XL Infra-Steam Sauna ($8,995) also fall into this category.
It combines infrared therapy with traditional rocks and steam, offering the benefits of infrared alongside a medical-grade red light therapy LED panel.
These models come with nicer features like built-in audio and more precise temperature controls than budget-friendly options.
Premium indoor saunas
The peak of splurging for indoor saunas is the premium tier. Our collection includes models like Golden Designs' Karlstad PureTech 6-Person and Nora PureTech™ 2-Person.
Both are full-spectrum hybrid saunas with Red Cedar Wood interiors and cost over $10,000.
These models command higher prices for high-end features like tempered glass doors, faster heating, smartphone app integration, and prefabricated kits for easy setup.
Our engineering team can analyze your site conditions, calculate heat loss based on your local climate, and recommend the ideal sauna system for your needs.
Cost of Outdoor Saunas: Price Breakdown
Outdoor saunas must withstand rain, sun, wind, and sometimes snow.
That usually calls for heavier-duty materials, such as treated wood or weather-resistant cladding, along with insulation and sealing to maintain heat despite outdoor temperature swings.
That's part of why they tend to be more expensive.
The various outdoor saunas from reliable brands in our collection range from $4,390 to $32,000.
Here's a table to put things in perspective:
| Outdoor Sauna Type | Price Range | Key Features |
| Entry-Level Outdoor Barrel or Compact Cabin Saunas | $4,000–$6,000 | Fits 1–2 people, basic wood construction, simple electric heater, DIY kits, minimal insulation, limited weatherproofing |
| Premium Outdoor Saunas | $6,000–$15,000 | Fits 4–6 people, high-end wood, advanced heater (digital control, faster heat-up), panoramic glass, ergonomic benches, LED lighting, rain/snow-resistant roofing |
| Luxury Custom Outdoor Saunas | $20,000–$35,000 | Custom-built, luxury finishes, smart controls, steam options, integrated sound system, large capacity (6+), designer-grade interiors, commercial-grade durability |
Under entry-level outdoor barrel or compact cabin saunas, you'll find models in our collection like SaunaLife's Model E6 and Model E7 Sauna Barrel.
More premium models like SaunaLife's Model G11 Sauna Kit and Model CL7G fall within the $6,000–$15,000 range.
Factors That Determine The Cost Of A Sauna
Factors like heating power, size, seating capacity, electric vs. wood heating, and installation cost all influence the price of a sauna unit.
1. Power
Entry-level heaters are best for small saunas (3–5 kW) and hold 30–40 lbs of stones. They're simple and budget-friendly.
Mid-range heaters work for 6–9 kW saunas. They look better, hold more stones, and offer smart Wi-Fi controls. They're also more durable than entry-level models.
Premium heaters offer sleek design, app control, and soft steam for a spa-like feel — ideal for luxury homes or commercial spaces.
2. Size and Seating Capacity
A sauna's size and seating capacity affect its cost because they determine how much material and equipment is needed.
You may see an expensive 2-person sauna, but rarely a cheap 6-person one.
A 1 to 2-person sauna costs $2,000–$4,500 indoors and $3,000–$6,000 outdoors. It's great for solo users, couples, and small spaces.
Even with a smaller heater, it heats up quickly, is energy efficient, and is easy to install (often plug-and-play).
A 4-person family sauna costs between $4,500 and $8,500 and is ideal for small families or group sessions.
It has a larger heater (6–8 kW), more space and seating, and typically requires professional installation and a dedicated circuit.
3. Electric vs. Wood Heating
The electric heating versus wood stove heating choice also matters.
While both fall under traditional saunas, they're quite different and carry different cost implications, both at installation and over time.
Purchasing and installing an electric sauna heater ranges between $800 and $3,500. It requires the right circuit breakers, wiring, and voltage to be checked and matched.
There are also ongoing costs — the electricity used each session and heater/sauna maintenance.
An electric sauna heater can hold a precise temperature, requires little maintenance, and is best for indoor or residential use. It's generally cleaner and easier to use than a wood stove heater.
A wood stove heater, on the other hand, needs firewood and isn't dependent on electricity. It gives off a more traditional feel and produces more natural heat.
4. Installation Cost Factors: Professional vs. DIY
Most people wonder whether they need a professional or can do it themselves — the answer depends on factors beyond just materials and equipment, including time, labor, and installation complexity.
Hiring a professional for an indoor sauna installation makes the electrical and plumbing work go smoothly.
In most places, sauna installation requires code compliance and permits, so it's often best to hire a professional who can secure those permits for you.
- Professional installation typically costs between $1,000 and $4,000, with the exact price depending on complexity, sauna size, and your region.
Beyond installation, outdoor saunas require site preparation — running electrical lines, leveling the site, preparing the foundation, assembling the roof, and more.
Our engineering team can analyze your site conditions, calculate heat loss based on your local climate, and recommend the ideal outdoor sauna system for your specific requirements.
Maintenance Cost for Saunas
Maintenance costs for infrared heaters are minimal — rare panel checks, some electrical use, and light cleaning — usually $20 to $50 per year.
Compare that to a wood stove sauna heater, which needs regular firewood, ventilation upkeep, ash and soot cleaning, and wood handling; maintenance there can run $300 to $1,000 per year.
Component replacement isn't frequent, though it can be pricey, especially for electric heaters and infrared saunas.
Overall, owning a sauna — indoor or outdoor, any type — brings real advantages, mainly the ease and comfort of having it accessible whenever you want it.
