Mr.Steam MX4 MS MAX Series 20kW Steam Shower Generator


Note: The Mr. Steam MX4E replaces the discontinued Mr. Steam MS SUPER 4E generator

Improving on the popular MS Super 4E, the MX4E is designed for home and day spa steam rooms up to 678 adjusted cubic feet (ACF). Required Control package sold separately.

The MS MX4E steam shower generator is constructed of durable stainless-steel throughout for years of safe, reliable, and efficient operation. The unit includes industrial-grade heating elements, a stainless-steel tank, ASME safety valve, electronic water-level control system, and a variety of other features.

Mr. Steam MX Series generators are engineered to provide the most consistent steam bathing experiences. The MX4E features the latest in steam bath technology and runs off an advanced microprocessor platform. The steam unit includes LED color indicators for easy-to-read self-diagnostics.

The MX4E generator features modular plug and play so that you may easily install steam shower accessories such as AromaTherapy, ChromaTherapy, and SteamLinx for a multisensory bathing experience.

The Mr. Steam MX4E 20kW steam generator is available in 208V and 240V single-phase (1PH) configurations. Mr. Steam MS-e Series generators are available in a variety of power ratings to best suit your needs.

The compact size of the generator allows the unit to be installed conveniently out of sight up to 60 feet away from the steam room. Typical installation locations include closets, vanities, and closets. The unit is perfect for any home steam shower kit.

The optional Express Steam feature is equipped with a built-in thermostat that maintains tank water temperature so that you may start steaming quickly.

The Mr. Steam MX4E generator requires the use of a Mr. Steam control or control package for operation. MS-e Series generators are compatible with all Mr. Steam controls and with the Steamlinx mobile app. Select the available control with features that best suit your bathing preference.

We recommend the available Mr. Steam AutoFlush Drain System with your MX4E steam shower unit. The Auto Drain automatically drains the generator tank after each use to help prevent sediment build-up and to ensure the best performance of the unit.

The MX4E steam bath generator is fully serviceable and carries a limited lifetime warranty. Mr. Steam MAX Series generators are US and Canadian UL listed and CE and NOM certified for your safety.

All Mr. Steam generators are designed, engineered, and crafted in America.
