Key Features & Comparison
Massive Stone Mass: Holding nearly 200 lbs of rock, the PC90 stays hot much longer than flat-wall electric heaters, preventing that "on-off" temperature cycling.
Versatile Steam Control: The open-mesh design allows for 360-degree water application, giving you total control over the humidity and "feel" of the sauna.
Space Efficiency: Because of its tall, slim profile, it occupies a very small footprint ($1.1\text{ sq ft}$), making it ideal for saunas where floor space is at a premium.
Integrated Controls: Usually available in two versions: the "PCE" (requires a separate digital wall panel) or the "PC" (features built-in knobs at the base for a simplified "plug-and-play" feel).
