“Not published” means Sun Home Saunas does not state this figure on the product page we read. We do not estimate missing specs or take them from review sites.

Our take

A full horsepower and a stated 32°F floor at inflatable-tub money. On paper it is the coldest-running unit under $4,000 in this catalog.

Worth knowing before you buy

Sun Home's own page lists water capacity inconsistently (80-90 gallons in one place, 300-360 L in another), so we have left the field blank rather than pick one. Sun Home also notes achievable min/max temperatures depend heavily on ambient conditions. Filter replacement is every 2-4 weeks.

We have not physically tested this unit. Everything above is either a manufacturer-published specification or an observation drawn from comparing those specifications across brands.
