We bought the 4 person barrel sauna from Costco for around $5 k about 10 years ago and set it up in the basement since it arrived in December and we wanted to try it out immediately …. The cedar is very thick and keeps the steam in/… so we left it setup down there and enjoy all year round …. We did need an electrician to hard wire to the Power Panel. I just had a sauna and swim this afternoon …. Means we keep our untreated pool open for cold plunge all the way at to November …. Best purchase ever …. Next to the 4 kayaks
