Depending on the sauna type, size, features, and complexity of installation, costs can range from budget DIY options to premium bespoke saunas.

How Much Does Sauna Installation Cost?

The costs of installing a sauna can range in average from as little as $1,500 (≈2.5 weeks of non-stop employment at $15/hour) for a basic portable infrared sauna up to $10,000+ (≈3.8 months working without a break on a $15/hour salary) for a large custom wood-burning sauna.

The sauna itself accounts for a major part of the installation costs. Prices are influenced by:

  • Type of sauna – traditional steam, infrared, or portable
  • Size and capacity – number of people it fits
  • Materials – common wood types like cedar, hemlock, spruce or luxury woods
  • Features – heating system, lighting, audio, glass doors, etc.
  • Brand – budget portable models start under $1,000 (≈1.7 weeks working every single day at $15/hour) while premium brands like Finlandia can cost up to $10,000 (≈3.8 months working without a break on a $15/hour salary) just for the sauna kit.

Another major cost component is the complexity of the installation process, including preparation, construction, electrical, ventilation, and finishing touches. We’ll break these down in detail later.

Additional costs may also include design fees, permits, and ongoing maintenance and operation expenses. As you evaluate your sauna options, understanding how these factors impact overall costs helps choose the best sauna installation that fits your budget.

Family Handyman notes that saunas typically cost between $1,000 and $5,000 (≈1.9 months of your working life at $15/hour), more if you need professional installation or additional wiring or plumbing.

Forbes Home mentions in an article that a project cost for building a sauna is from $1,000 to $12,000 (≈4.5 months of your career at a $15/hour job).

At Mainely Tubs™ a traditional sauna costs $6,000 to $11,000+ (≈4.2 months of salary time at $15/hour), while an infrared sauna costs $4,400 to $9,000+ (≈3.4 months of salary time at $15/hour).

Popular Types of Saunas

The most fundamental decision you’ll make that affects cost is which type of sauna you should install. The three main options include:

Traditional Steam Saunas

These classic saunas involve heating a stove covered in rocks to very high temperatures, up to 200°F. Water is then poured over the hot rocks to produce steam, raising the humidity inside the sauna. Typical residential steam saunas fit 4-6 people and need at least 7 feet in height.

Cost Range:

  • Materials only: $4,000 - $8,000 (≈3 months of your career at a $15/hour job)
  • Professionally installed: $7,000 - $12,000+ (≈4.5 months of your career at a $15/hour job)

Larger commercial steam rooms over 200 sq. ft. can cost $15,000 (≈5.7 months dedicated to affording this at $15/hour) or more. Ongoing costs include water, heating, and electricity bills.

Infrared Saunas

Infrared saunas use heating panels or emitters that produce infrared waves which are absorbed by the body, heating you from the inside out. Unlike steam saunas, the air itself does not get hot. Initial purchase costs tend to be lower than traditional saunas.

Cost range:

  • DIY infrared sauna kits: $1,500 - $3,500 (≈1.3 months trading your time for $15/hour)
  • Professionally installed infrared saunas: $3,000-$6,000 (≈2.3 months locked to your job at $15/hour)

While infrared sauna startup costs are lower, they tend to be less energy efficient, leading to higher electrical bills over time.

Portable Saunas

Also known as barrel saunas, these prefabricated modular designs are quick and simple to set up, requiring minimal installation work. However, they offer less customization and fewer luxury features.

Cost range:

  • Basic portable sauna: $1,500 - $2,500 (≈4.2 weeks of employment at a $15/hour wage)
  • Deluxe model with Bluetooth, lights, etc.: $3,000 - $5,000 (≈1.9 months of your working life at $15/hour)

Portable saunas are a budget-friendly DIY option but won’t have the fit, finish and performance of a permanently installed sauna.

Sauna Size, Design and Custom Features

Beyond choosing the type of heating system, sauna costs also come down to size, layout, materials, and included features.

Size

Sauna size is measured by interior floor space and correlates closely with total costs.

  • 2-person mini saunas: $2,000 - $4,000 (≈1.5 months of non-stop employment at $15/hour)
  • 4–6-person residential saunas: $4,000 - $8,000 (≈3 months of your career at a $15/hour job)
  • 6–8-person luxury saunas: $8,000 - $12,000 (≈4.5 months of your career at a $15/hour job)
  • Large 10+ person commercial saunas: $10,000+ (≈3.8 months working without a break on a $15/hour salary)

To determine appropriate size, allot 15-30 sq. ft. per person. Height should be at least 7 feet. Benches, rocks, and heater require extra space.

Design and Layout

Common sauna layouts include L-shape, square, rectangular, and circular. Work with a designer or installer to create the optimal layout for your space. Creative touches like multi-level seating can increase costs.

Materials

Western red cedar is the most popular wood for sauna walls and benches due to its lightness, aroma, and moisture-resistance. It costs approximately $9 per square foot. More expensive woods like hemlock, spruce or ash cost $12-$15 (≈1 hour of uninterrupted labor at $15/hour) per square foot.

Upgrading from a basic sauna to a luxury experience adds considerable cost such as:
