9kW Steam Shower Generator
This residential steam generator is built for reliable, quiet, and efficient performance. Made with stainless steel and industrial-grade components, it includes a smart control system, LED diagnostics, a full-port drain valve, and advanced water flow tech.
It produces steady steam using minimal water—less than 2 gallons per 20-minute session—making it eco-friendly and cost-effective.
Compact enough to install up to 60 feet from the steam room (in a closet, vanity, or cabinet), it’s compatible with all Mr. Steam controls and the SteamLinx app.
Optional features like Express Steam let you heat up faster with a built-in thermostat. Pair it with the Auto Drain system to reduce mineral buildup and extend the unit’s life.
Fully serviceable, UL listed, and backed by a limited lifetime warranty.
