How Much Does It Cost to Build a Home Sauna?

So, you've decided to invest in your health and relaxation by building a home sauna. Great choice!

But now you're probably wondering, how much does it cost to build a home sauna?

In this article, we'll explore the various factors that can influence the cost of building a home sauna, provide some cost estimates for different sauna types, and discuss additional costs you should consider.

Factors Affecting Sauna Cost

Sauna Type

There are several types of saunas available, and each comes with its own set of cost factors. Traditional saunas, infrared saunas, pre-built modular saunas, and custom-built saunas all have different price points and associated costs.


The size of your sauna will have a significant impact on the overall cost. Larger saunas require more materials and labor, which translates to higher costs.


The materials you choose for your sauna will also play a role in determining the cost. High-quality woods like cedar, hemlock, or redwood can drive up the price. However, using more affordable materials, like spruce or pine, can help keep costs down.

Heating Source

The heating source you choose for your sauna will impact the cost as well. Traditional saunas use electric, gas, or wood-burning stoves, while infrared saunas use infrared heaters. Each heating source has its own pros and cons, as well as associated costs.


Where you plan to build your sauna can also affect the cost. Building a sauna in an existing space or as an addition to your home may be more affordable than constructing a standalone structure.

Labor and Installation

The cost of labor and installation is another crucial factor to consider. Depending on the type of sauna, you may need to hire a professional to handle the installation, which can add to the overall cost.

How Much Does It Cost To Build a Sauna Estimates by Type

Pre-cut Sauna Kits


Pre-cut sauna kits are a budget-friendly option that allows you to build a traditional sauna by assembling pre-cut materials. These kits typically range from $2,000 to $6,000, depending on the size, materials, and heating source.

Pre-built Modular Saunas

Pre-built modular saunas are another cost-effective choice for those looking to build a home sauna. These saunas come in pre-assembled sections that can be easily put together on-site. Prices for pre-built modular saunas range from $3,000 to $10,000, depending on the size, materials, and included features.

Custom-built Saunas

Custom-built saunas provide the most flexibility in terms of design and materials but also come with a higher price tag. The cost of a custom-built sauna can vary widely, from $10,000 to $25,000 or more, depending on the size, materials, heating source, and complexity of the design.

Infrared Saunas

Infrared saunas use infrared heaters to warm the body directly, rather than heating the air around you. This type of sauna is often more energy-efficient and has lower operating costs compared to traditional saunas. Infrared saunas typically cost between $2,000 and $7,000, depending on the size and features.

Additional Costs to Consider When Building a Home Sauna


When budgeting for your home sauna, don't forget to account for the cost of accessories, such as benches, backrests, sauna stones, and thermometers. These items can add several hundred dollars to the overall cost, depending on the quality and quantity you choose.

Maintenance and Upkeep

Maintaining your home sauna is essential for its longevity and performance. Be prepared to budget for the cost of regular maintenance, such as cleaning and sealing the wood, as well as replacing worn or damaged components. Additionally, consider the cost of electricity or other fuel sources for your sauna's heating system.


In conclusion, the cost of building a home sauna can vary greatly depending on several factors, such as the type of sauna, size, materials, heating source, location, and labor and installation costs. By understanding these factors and considering additional costs like accessories and maintenance, you can make an informed decision when planning and budgeting for your home sauna project.


  1. Is it cheaper to build a sauna yourself or buy a pre-built sauna?

Building a sauna yourself using a pre-cut kit or constructing a custom sauna can be more cost-effective than purchasing a pre-built modular sauna, depending on your specific needs and preferences. However, pre-built saunas offer convenience and ease of assembly that may be worth the extra cost for some individuals.

  1. How much does it cost to run a home sauna?

The cost of running a home sauna will depend on the type of sauna, the heating source, and the frequency of use. Infrared saunas tend to be more energy-efficient than traditional saunas, resulting in lower operating costs. Be sure to factor in the cost of electricity or other fuel sources when budgeting for your home sauna.

  1. What is the best type of wood for a home sauna?

Cedar, hemlock, and redwood are popular choices for sauna construction due to their natural resistance to moisture, decay, and insects. However, more affordable options like spruce or pine can also be used if you're looking to keep costs down.

  1. Can I build a sauna in my existing bathroom or basement?

Yes, it is possible to build a sauna in an existing space like a bathroom or basement, as long as there is proper ventilation and sufficient space to accommodate the sauna's size and heating source requirements. Building a sauna in an existing space may be more cost-effective than constructing a standalone structure.

  1. Do I need a professional to install my home sauna?

The need for professional installation will depend on the type of sauna you choose. Pre-cut kits and some pre-built modular saunas can often be assembled by a skilled DIYer
