What kind of electricity do you need for this four man sauna? Would it require extra electrical cost and electrician? Can someone come and install this unit in my apt? Thank you

This sauna requires a 110 volt 20 amp outlet. Back on the product page, if you click on the tab labeled "More..." you will see a picture comparing a 110 volt 15 amp outlet and a 110 volt 20 amp outlet. Normally we do not assemble the saunas as they are designed for simple at home assembly. We do have a company that can perform a white glove service if you are interested, which would probably cost between $250 and $300.
