You can build a sauna at home
You can build a sauna from scratch in a basement, garage or even an attic. Electric saunas and infrared saunas are best for indoor use. Outdoors, the sauna can be added to the deck or porch, or built on its own.
Infrared saunas are best for families
Offers milder temperature environments - 120 to 150 degrees Fahrenheit. Additionally, infrared sauna light can penetrate deeper into the body, which means they produce more intense sweat, albeit at a cooler (and more comfortable) temperature.
The cost of installing a home sauna ranges from $3,000 to $6,000, with an average price of $4,500. These fees will fluctuate based on the size of the sauna, the materials used in the construction, and any custom elements your professional adds.
Saunas do not consume electricity
As a rough calculation, a 1000W sauna will use about 1 kWh (1 kW/h) of electricity. So you can calculate the cost by multiplying the energy used by the sauna by the power company's rate of 1 kilowatt per hour.
Do saunas need plumbing?
For very small saunas (3' x 4' x 6 1/2' ceiling), the heater will plug into a 110V/120V outlet as long as there is a #12 wire behind the plug. There are no plumbing requirements unless a floor drain is required. The drain is not required, just an accessory for cleaning.
