Because many home saunas come prefabricated, the installation cost of the sauna itself will stay relatively the same no matter where you live. The only real factor that comes into play is the cost of labor in your area.

  • New York: $4,500

What Home Sauna Can I Get on My Budget?

Whether you want a sauna meant for one or you entertain often, there’s an option for everyone. Take a look at the sauna installation costs below, broken down by a range of budgets.

$1,000 to $3,000

For a budget of $1,000 to $3,000, you’re going to be looking at personal saunas that fit one to two people at the most. Sauna prices typically include labor and installation.

$3,000 to $4,500

Sauna prices for a budget of $3,000 to $4,500 will allow you to get a sauna that fits four people or allows you to spread out in comfort. Depending on where you fall in this range, you may be able to choose a different wood, like pine, cedar, or spruce for your sauna.

$4,500 to $6,000

For those with a budget of $4,500 to $6,000, you can grab a prefabricated that fits upwards of seven people. You can opt for add-ons like a small halogenerator, which is used for dry salt therapy. Or switch out the sauna rocks for a wood-burning option at this budget if you don’t need more space.

$6,000 and Above

At $6,000 and above, you can have a custom-built sauna made for you. You can choose woods like Nordic White spruce or redwood, which tend to hold up better over the years and add more color to your sauna. Nordic White spruce offers a light, brown color while redwood wood has a lovely red accent.

How Much Does It Cost to Build a Home Sauna Yourself?

A small one to two-person in-home sauna costs around $1,000 to $1,500 and you can put that in your desired location relatively easily. Unless you’re a plumber and an electrician, you should hire a pro to take care of the plumbing and electricity hookups. You’ll need to ensure that the sauna drains properly and it doesn’t short out while you’re inside.

For bigger saunas, you’ll want to hire a sauna installer. These contractors will put in the heating element, windows, and doors and ensure they seal everything properly. Without proper sealants, your sauna will turn into your home’s new heater instead.

Home Sauna Cost Breakdown

Because the cost of building a sauna tends not to fluctuate that much since they’re often prefabricated, the majority of the price comes from labor. The only time this changes is if you go for a custom-built house sauna.

Labor

Regardless if you have someone install a sauna for you or you do most of the work yourself, you’ll need to pay for labor. If you have them install and hook it up for you, you’re looking at $800 to $1,200 in labor costs.

If you want to install it yourself, you’ll need an electrician and plumber to come out and hook it up. A plumber costs around $45 to $200 per hour and an electrician will charge around $50 to $100 per hour.

Warranties

Depending on who you buy the sauna from, they may offer a warranty. A warranty for a sauna will cost around $300 to $1,200, depending on the lifespan of the warranty. Inquire about a warranty with the company you purchase from, as sauna repairs can range between $170 to $600, which may make the warranty worth it.

Materials

Even prefabricated saunas give you different options to choose from when it comes to the type of wood you want the sauna enclosed in. You’ll also often have the option to install a window, which may increase the price by $100 to $300, depending on the size of the window.

How Much Does It Cost to Build a Home Sauna by Type?

Custom-built saunas give you the opportunity to customize the dimensions of the sauna. You can also pick what type of material you choose to build with, and whether you want a dry-heat, wet-heat, wood-burning, or infrared option. These options are available for prefab saunas as well, but the availability of these options comes down to the company you purchase from.

Material of the Sauna

Wood prices will fluctuate based on the rarity of the tree it comes from and where it ships from. You also have the option for fiberglass or acrylic, which may hold up better over time but often have high repair costs.

Standard wood prices and their costs per square foot:

  • Pine: $2–$4

  • Cedar: $3–$7

  • Spruce: $4–$8

  • Hemlock: $6–$9

  • Nordic White spruce: $13–$20

  • Redwood: $30–$35

Dry Saunas

Dry saunas are the standard heating method in most saunas. They use electricity or gas to heat the rocks and create the warmth you’re used to feeling in a sauna. This method is typically included in the price.

Wet Saunas

Wet saunas add the ability to make steam. You simply add water to the rocks and they release steam, which may momentarily make it hotter in the room. Wet saunas are an add-on, which will cause the price to rise from around $100 to $200.

Wood-Burning Saunas

Wood-burning saunas are good for outside saunas, but they often cost more to operate. These saunas use burning wood in a heat-resistant container to fill the sauna with warmth. On average, wood-burning saunas will cost around $500 to $1,000 extra, depending on the size of the sauna.

Infrared Saunas

Infrared saunas offer a different take on heating altogether. The previous methods focus on heating the environment you’re sitting in. Whereas with infrared saunas, the main item it’s trying to heat is you.

Infrared sauna prices are often cheaper than wet or wood-burning saunas but tend to stay around the same price as a dry sauna. You’ll pay on average around $4,200 for an infrared sauna. Your cost will change depending on the type of wood you choose and the size of the infrared sauna itself.

FAQs About Home Saunas

Does a home sauna increase the value of your home?

Some homeowners consider a home sauna to be a luxury item, which means you may notice an immediate return on investment for the value of your home.

If you’re using an electric-powered sauna, it costs around $0.12 to $0.50 per hour. Every state has different kilowatt rates. The sauna guide will let you know how many kilowatts it uses per hour.

Where do most people put their home sauna?

Most people will opt to put their home sauna outside near a pool or on a screened-in porch so the heat doesn’t move into the rest of the house. If your house has enough room, you may choose to put it in a bathroom so you can shower right after.
