Saunas come in various forms, each offering a unique experience. Understanding the different types of saunas is essential for making an informed decision, whether for personal use or commercial purposes. 

This section explores the characteristics and cost factors associated with traditional saunas, infrared saunas, and portable saunas and compares steam rooms with sauna rooms.

Traditional Saunas: Description and Cost Factors

Traditional saunas, also known as Finnish saunas, use a wood, electric, or gas heater to warm the air inside the room to temperatures typically between 150°F and 195°F. The heat in these saunas is dry, although water can be thrown onto heated sauna rocks to create a burst of steam.

Cost Factors:

Size and Capacity: A small home sauna installation cost for 2-4 people can cost between $2,000 and $5,000, while larger models can exceed $10,000.

Heating System: Electric heaters are generally less expensive than wood-burning options. An electric heater might cost between $500 and $1,500.

Materials: High-quality, durable woods like cedar or hemlock are commonly used, affecting the price. Cedar can be more expensive due to its longevity and resistance to moisture and insects.

Installation: Professional installation can range from $1,000 to $3,000, depending on complexity.

Infrared Saunas: Description and Cost Factors

Infrared saunas differ from traditional saunas as they use infrared panels to heat the body directly instead of heating the air. Infrared sauna operates at lower temperatures, usually around 120°F to 150°F, making them more comfortable for some users.

Cost Factors:

Type of Infrared Technology: Far infrared saunas (FIR) are typically more affordable than Near-infrared (NIR) ones. Prices range from $1,000 to $5,000.

Size: Smaller units for 1-2 people are less expensive, while larger units can cost more due to increased materials and technology.

Wood Type: Like traditional saunas, the choice of wood impacts the cost.

Additional Features: Extras like chromotherapy lights or Bluetooth speakers can increase the price.

Portable Saunas: Description and Cost Factors

Portable saunas offer a convenient and space-saving solution. They come in various forms, including foldable tents and small cabins. Most portable saunas use infrared technology, but some steam versions are also available.

Cost Factors:

Type: Infrared portable saunas are generally more expensive than steam portable saunas. Prices can range from $150 for basic models to around $1,000 for high-end versions.

Materials and Durability: Higher-priced models tend to use more durable materials and offer better insulation.

Features: Additional features like remote controls or auto shut-off functionality can affect the price.

Steam Rooms vs. Sauna Rooms: Differences and Respective Costs

Steam rooms, often confused with saunas, generate moist heat through a steam generator. Unlike the dry heat of a sauna, steam rooms maintain 100% humidity at lower temperatures, usually around 110°F to 120°F.

Cost Differences:

Steam Rooms: The cost of a home steam room setup, including the generator, can range from $2,500 to $6,000, depending on size, features, and if you want a steam room shower.

Sauna Rooms: As mentioned earlier, traditional and infrared saunas have different cost structures, typically ranging from $1,500 to over $10,000 based on type, size, and features.

Both steam rooms and sauna rooms may offer unique experiences and health benefits. The choice depends on your preference, budget, and available space.

Outdoor Saunas: Description and Cost Factors

Outdoor saunas offer the experience of enjoying sauna benefits while being immersed in an outdoor environment. They are particularly favored in scenic areas or by those who wish to integrate their sauna experience with nature. 

Outdoor saunas come in various types, including traditional wood-fired, electric, and infrared models. Their design features robust construction with materials that are resistant to weather, ensuring durability against external elements. Many outdoor saunas are crafted to blend with garden or backyard landscapes.

The cost factors for an outdoor sauna include weatherproofing and using materials and insulation suited to handle moisture and temperature variations. The size and capacity of the sauna are major determinants of cost, with options ranging from small, two-person cabins to larger structures. Outdoor sauna installation costs can be higher than indoor saunas due to requirements for a proper foundation, electrical wiring, and possibly plumbing, especially in the case of traditional saunas. 

The choice of heating source also influences the cost; wood-fired heaters may have lower initial costs but require ongoing maintenance and a steady wood supply. Electric and infrared models, while potentially more expensive upfront, often offer greater convenience and ease of maintenance. The installation of these heaters requires careful planning, especially in terms of electrical access and safety standards.

The average price range for outdoor saunas varies significantly. Basic outdoor sauna costs around $2,500, including smaller cabins suitable for two people. On the higher end, prices can exceed $10,000 for larger and more luxurious installations. These high-end models may feature extensive customization, larger dimensions, and premium materials, providing an exceptional sauna experience in a home or commercial setting.
