So you want to build your own outdoor sauna room but don't know where to start? Well, building a backyard sauna is not rocket science but you do need to know a few things before starting your sauna building project. You have to assess your budget, the purpose of your sauna, the size of your backyard, and whether you want a DIY sauna kit or a custom-built sauna. As you can see a lot of things go into the decision of building an outdoor sauna. In this article, we will be discussing the things you need to do and know before starting your

How much will it cost to build your own sauna?

There is no simple answer to this question as the cost of building a sauna depends on a variety of factors such as the size of the sauna, the type of sauna, and whether you are using a DIY sauna kit or having a custom-built sauna.

Generally speaking, the cost of building an outdoor sauna ranges from $3000 to $15,000. If you are on a tight budget, you can always opt for a cheaper and smaller sauna room or DIY sauna kits.

Electric and gas saunas will be more expensive to run than wood-burning saunas. Hence, if you are looking for a more cost-effective option, a wood-burning sauna would be your best bet.

However, if budget is not a big issue, you can go with an infrared sauna.

As we said the cost will also depend on the size of the sauna. If you want a small 2-3 person sauna, it will cost you less than building a 6-8 person sauna.

The type of sauna also plays a role in deciding the cost. If you want a luxurious and feature-rich sauna room, it will cost you more than basic sauna rooms.

Different types of saunas

Let’s take a look at the different types of saunas that you can choose from:

1. Infrared saunas

Infrared saunas are known for their health benefits. They use infrared heaters to generate waves to heat the body directly without heating the air around you. Hence, they are more effective and efficient than traditional saunas.

If you have health issues like arthritis, joint pain, or muscle soreness, infrared saunas can help you get relief from the pain. They are also known to boost blood circulation and detoxify the body.

2. Electric saunas

As the name suggests, electric saunas use electricity to generate heat. They are easy to install and can be placed anywhere in your house.

If you are planning to build it outdoors, make sure to have an electric line so that the sauna can be connected to a power source. These saunas use electric sauna heaters to generate heat. They are very easy to maintain and are quite popular among sauna enthusiasts.

3. Wood-burning saunas

If you are looking for a traditional sauna, wood-burning saunas are the way to go. These saunas use a wood-burning stove to generate heat.

One of the main advantages of these saunas is that they can be built outdoors. However, these saunas do need regular maintenance and care.

The smoke that is produced by the wood-burning stove can damage the exhaust pipe and the sauna heater if not properly taken care of.

But if you are looking for a traditional and authentic sauna experience, wood-burning saunas are the way to go.

4. Portable saunas

If you are tight on budget or don’t have a big place to accommodate a sauna, portable saunas are the way to go.

As the name suggests, these saunas can be easily assembled and disassembled. They are very easy to store and can be taken with you anywhere you go.

Portable saunas are perfect for small homes and apartments as they don’t take up much space. You can get a portable bike sauna if you love biking and want to take your sauna with you on biking trips.

5. Traditional Finnish sauna

If you want to experience the authentic sauna experience, Finnish saunas are the way to go.

These saunas are very popular in Europe and the North American sauna society and are known for their health benefits. They use dry heat to detoxify the body and improve blood circulation.

Finnish saunas are usually big and can accommodate a large number of people. They are perfect for social gatherings and family get-togethers.
