The Outpost

A $26,495 pre-assembled red cedar sauna with a 9 kW heater and a 3-year warranty; the data does not say what shape it is.

Outpost is one of the dearest saunas in our data: 6 seats at $4,416 each, about three times the all-model median. It is 99 by 75 inches and 108 inches tall, the tallest we record, with a 9 kW heater, tied for the largest, which is 1.5 kW per seat, exactly typical. It arrives pre-assembled, one of only five that do.

Its closest comparison is the Auroom Garda, six seats pre-assembled at $32,990, about $6,500 more. A cedar barrel kit from Almost Heaven costs $6,191 for the same seats. The warranty is 3 years, short for this price. Our data has no shape and no weight, so look at the maker's page before deciding. The price is justified only if delivery already built matters. Sweat Kingdom is the only store.
