Depending on the size and type of sauna you plan on purchasing, different electrical requirements will be needed. I would say that 90% of saunas will require at least minimal work from an electrician. If you opt for a traditional model you'll need to wire your house for 220V-240V therefore, you will need to hire an electrician to set it up for you. Hiring an electrician will ensure you get the most secure and efficient electrical configuration for your sauna. All of our traditional sauna heaters /steamers are hardwired and must be connected directly to the electrical line. If you opt for an infrared sauna, depending on size you'll either have the option to plug it into a standard outlet or will need an electrician to assist. All models will require 220V-240V except smaller 1 person units.
