The Logan squeezes a full traditional sauna — Harvia 6kW heater, 180°F, real löyly — into a footprint the company pitches for apartments, bathrooms, and closets. It delivers genuine single-occupant luxury, but $4,172 for one seat and a hardwired 240V/30A circuit make it an expensive and surprisingly demanding small appliance.

The Logan answers a specific question: what is the smallest genuinely traditional sauna you can put indoors? At 53¼" x 36" x 77⅝" outside (49" x 31¾" inside) it is pitched for apartments, bathrooms, and closets, sits on your existing flooring, and still runs a full Harvia 6kW heater that Almost Heaven states reaches 180°F in an hour, with a delayed start programmable up to eight hours. The $4,172 base configuration is Rustic Red Cedar with a glass door and the dial-controlled KIP heater; Hemfir lumber, a half-and-half door, and smart Harvia heaters with the Fenix Wi-Fi control push the configurator to about $6,800.
The trade-offs are concentrated in the economics and the wiring. One bench (31¾" x 18") means one bather, so the cost per seat is the highest of Almost Heaven's line, and the heater still demands a hardwired 240V/30A circuit plus a 110V/15A plug-in lighting feed — the same electrical work as the brand's three-person rooms. Coverage is the familiar split: limited lifetime on the room, 1 year on Harvia heating elements, 5 years on other heater components. No assembled weight is published, and unlike the base Salem or Madison the Logan listed no compare-at discount at the time of research, so the sticker is the price.
