Preliminary steam-shower sizing, placement, and coordination in one workspace
How is the generator sized?
The base calculation is finished width × depth × height. Current KOHLER guidance recommends an 8-foot-or-lower ceiling and advances one generator size for each foot above 8 feet, without exceeding a model’s published maximum.
The planner pairs the current K-323xx generator sequence with a documented mechanical, Anthem+, or DTV+ controller and compatible round, square, or linear steam head. Tandem systems show two generators, circuits, steam heads, and drain pans.
Final electrical, plumbing, waterproofing, vapor, structural, code, equipment, and installation decisions depend on the actual project. This tool is a discussion aid—not a permit, engineering, or construction document.
