The warranty page also rules out extension cords and non-dedicated circuits. The same page requires at least 5 ft between the sauna and a cold plunge, shower or bathtub. The product page doesn't say whether you need an electrician or GFCI protection. It points you to the spec sheet for electrical details. Sunlighten's support page links an owner's manual, spec sheet, assembly guide and power box installation guide. Those PDFs couldn't be opened for this review.
