The Watoga adds a foot of interior depth over the Salem, stretching the same Harvia 6kW platform to a nominal four-person capacity with the same limited lifetime warranty. Almost Heaven itself concedes on the page that four is cozy — "if you like extra elbow room, you might want to size up" — and the hardwired 240V requirement and outdoor assembly remain unavoidable.

The Watoga sits between the compact Salem and the larger barrels in Almost Heaven's classic line: the interior runs 75¼" wide by 51¼" deep by 69¼" high, with two 51¼"-long benches, and the company rates it for two to four occupants while candidly suggesting buyers who want elbow room size up. The $5,184 base configuration pairs Rustic Red Cedar staves with a Harvia 6kW KIP heater on manual dials; the same configurator as the rest of the line adds Onyx-finish lumber, arched doors, port or vista windows, and smart Harvia heaters with the Fenix Wi-Fi control, topping out near $7,800. Unlike the Salem, the base Watoga listed no compare-at discount at the time of research.
The practical profile is identical to its smaller sibling: a kit that ships within 6–8 weeks, outdoor assembly on a 54" cradle, a hardwired 240V/30A circuit for the heater, and a separate 110V/15A plug-in feed for lighting. The room carries Almost Heaven's limited lifetime warranty against manufacturing defects while the Harvia heater gets 1 year on elements and 5 years on other components. The page publishes no assembled weight, no exterior dimensions, and no model-specific maximum temperature — its generic heater-type chart lists electric saunas at 150–195°F — so shoppers comparing barrel-to-barrel heat performance are left to infer from the shared 6kW heater.
