How to Size Your Steam Generator

The correct kW output depends on your steam room’s cubic footage and wall material. As a general guide:

  • Under 100 cu ft — 6–9 kW
  • 100–200 cu ft — 9–12 kW
  • 200–500 cu ft — 12–18 kW
  • 500–1,000+ cu ft — 18–30+ kW
  • Tile and stone enclosures require higher kW than acrylic or fiberglass

Frequently Asked Questions

  • What size generator do I need? — Match kW output to your steam room’s cubic footage using the guide above
  • Are these easy to install? — Most units are designed for professional installation and include detailed guidelines
  • Where is the generator installed? — Typically in a nearby cabinet or utility space within 25 feet of the steam room
