Mr.Steam MSSUPER3E MS-E Series 15kW Steam Shower Generator

The Mr. Steam MS Super 3E is a high-performance steam shower generator designed for residential and light commercial steam rooms ranging from 412 to 482 adjusted cubic feet (ACF). Built with premium materials and advanced technology, this 15kW steam generator delivers consistent, efficient, and safe steam bathing experiences for years to come.

Crafted with surgical-quality stainless steel throughout, the MS Super 3E ensures unmatched durability and corrosion resistance. At the heart of the unit lies an intelligent microprocessor-based operating system, delivering precise steam control, energy efficiency, and reliable functionality. Features like a precision temperature probe, industrial-grade heating elements, and advanced water solenoid technology contribute to its ultra-efficient performance.

The SteamBath technology in the MS Super 3E optimizes steam dispersion for even and comfortable steam distribution. Its proprietary dispersal chamber regulates steam output to maintain ideal humidity levels throughout your steam session. Thanks to its eco-conscious design, this generator uses less than one gallon of water in a 20-minute session, making it both cost-effective and environmentally friendly.

Compact and versatile, the generator can be installed up to 60 feet away from the steam room in closets, vanities, or utility rooms. It’s available in 208V (MSSUPER3EB1) and 240V (MSSUPER3EC1) single-phase configurations. Optional features such as Express Steam allow for rapid startup by keeping tank water warm between sessions.

Fully serviceable and backed by a limited lifetime warranty, the MS Super 3E is UL, CUL, NOM, and CE listed for safety and quality assurance. Like all Mr. Steam products, it is designed, engineered, and made in the USA.
