How Much Does an Outdoor Sauna Cost? (Complete Guide)

An outdoor sauna is an excellent addition to any home, offering numerous health benefits such as relaxation, improved circulation, and stress relief.

As the demand for outdoor saunas has increased, so have options and price points.

But how much should you expect to spend on your dream outdoor sauna?

In this article, we’ll explore the factors that influence the cost of an outdoor sauna and provide a detailed breakdown of what you can expect to pay.

Factors Affecting the Cost of an Outdoor Sauna

Size and Capacity

The size and capacity of your outdoor sauna will significantly impact the overall cost.

A small sauna designed for two people will be more affordable than a large sauna that can accommodate six or more individuals.

Remember that a more giant sauna requires more materials and energy, which adds to the total cost.

Material and Design

The materials used in constructing your outdoor sauna will also affect the price.

Traditional saunas are typically made from cedar, hemlock, or spruce, while modern designs may feature glass or other materials.

Additionally, the complexity of the design and architectural features can increase costs.

Type of Heater

The type of heater used in your outdoor sauna is another essential factor to consider.

Electric heaters are the most common and often the most affordable option, but infrared and wood-burning heaters are also available.

Each heater type has its own set of benefits and drawbacks, so research your options carefully.

Installation and Labor Costs

Installation and labor costs can vary widely depending on the complexity of the project and the professionals you hire.

Pre-fabricated saunas generally have lower installation costs, while custom-built saunas may require more labor and expertise.

Location and Site Preparation

The location of your outdoor sauna can also influence the cost.

Factors like accessibility, distance from your home, and the need for additional utilities (such as electricity or water) can add to the overall expense.

Site preparation, including leveling the ground and creating a foundation, will also contribute to the cost.

Additional Features

Customizing your outdoor sauna with additional features like sound systems, lighting, or advanced control panels can increase the overall cost.

While these extras can enhance your sauna experience, they are optional for a functional and enjoyable outdoor sauna.

Popular Outdoor Sauna Models and Their Costs

Pre-Fabricated Outdoor Saunas

Pre-fabricated outdoor saunas are ready-made units that can be quickly assembled on-site.

These saunas are available in various sizes and designs, ranging from $3,000 to over $15,000.

Pre-fabricated saunas are generally more affordable and easier to install than custom-built options.

Custom Outdoor Saunas

Custom outdoor saunas are designed and built according to your specifications, allowing you to create a unique and personalized experience.

These saunas can be tailored to fit your space and preferences, but they tend to be more expensive than pre-fabricated options.

Custom outdoor saunas can cost anywhere from $10,000 to over $30,000, depending on the size, materials, and design complexity.

DIY Outdoor Sauna Kits

DIY outdoor sauna kits provide a more affordable option for those who enjoy a hands-on approach.

These kits include all the necessary materials and instructions to build your outdoor sauna, typically costing between $2,000 and $10,000.

Remember that DIY sauna kit costs do not include labor or installation fees, and you may need to hire professionals if you need more confidence in your construction abilities.

Types of Outdoor Saunas

There are three main types of outdoor saunas to choose from, each with its own unique features and benefits.

 A. Barrel Saunas

Barrel saunas have a distinct, round shape that maximizes interior space and allows optimal heat circulation. They are often made from high-quality cedar or other durable wood types.

 B. Cabin Saunas

Cabin saunas are more traditional, featuring a rectangular or square shape. They are versatile and come in various sizes, materials, and styles.

 C. Outdoor Infrared Saunas

Infrared saunas use infrared heaters to emit radiant heat, which is absorbed directly by the skin. They typically have a lower temperature than traditional saunas and may be more energy-efficient.

Operating and Maintenance Costs

In addition to the initial cost of purchasing and installing your outdoor sauna, you should consider ongoing operating and maintenance costs.

These expenses may include electricity or fuel for your heater, water (if you have a steam sauna), and routine maintenance like cleaning and replacing filters.

Operating costs can vary depending on the size and efficiency of your sauna and local utility rates.

You can expect to spend between $50 and $200 monthly on electricity for a small to medium-sized electric sauna.

Wood-burning saunas may have lower operating costs but require more manual labor to maintain.

Money-Saving Tips

If you’re looking to save money on your outdoor sauna, consider these tips:

  1. Opt for a smaller sauna, as larger saunas require more materials and energy.
  2. Choose a pre-fabricated or DIY sauna kit over a custom-built sauna.
  3. Research and compare various heater types to find the most energy-efficient option.
  4. Install your sauna in a location with easy access to utilities, minimizing additional expenses for electrical or plumbing work.
  5. Limit the use of additional features and accessories that can increase costs.


The cost of an outdoor sauna can vary widely, depending on factors like size, materials, and installation.

On average, you can expect to spend anywhere from $3,000 to over $30,000 for a pre-fabricated, custom, or DIY outdoor sauna.

Be sure to consider the ongoing operating and maintenance costs when budgeting for your sauna.

With careful planning and research, you can find the perfect outdoor sauna to fit your needs and budget.
