Mr. Steam MS90E 5kW Steam Shower Generator
Transform your home into a luxurious wellness retreat with the Mr. Steam MS90E, a 5kW steam generator designed for residential steam rooms up to 71 adjusted cubic feet (ACF). Control package sold separately.
Innovative Technology for Premium Steam Experiences
Built to deliver years of quiet, clean, and efficient performance, the MS90E features intelligent SteamBath technology and an advanced microprocessor platform. It’s the perfect choice for creating a rejuvenating steam bath experience right in the comfort of your home.
Top-Tier Construction and Features
The MS90E is crafted with surgical-grade stainless steel and equipped with industrial-quality heating elements, advanced water solenoid technology, LED diagnostic indicators, and a full-port drain valve for superior durability and convenience.
Eco-Friendly and Energy-Efficient
With its proprietary dispersal chamber, the MS90E ensures a consistent and relaxing steam experience by precisely controlling water flow. Using less than two gallons of water during a 20-minute session, this unit is as economical as it is eco-conscious.
Compact Design for Versatile Installation
Measuring about the size of a suitcase, the compact MS90E can be discreetly installed in a variety of locations such as closets, cabinets, or vanities, up to 60 feet away from the steam room. It’s designed to fit seamlessly into any home steam shower setup.
Optional Express Steam Feature
Upgrade with the Express Steam feature to maintain pre-heated water and enjoy instant steam sessions without the wait.
Custom Controls for Personalized Relaxation
Pair the MS90E with any compatible Mr. Steam control or the SteamLinx mobile app to customize your steam bath settings, including temperature and session duration.
Recommended Maintenance for Optimal Performance
Keep your steam generator running at its best with the optional Auto Drain system. This add-on automatically flushes the tank after each use, preventing mineral build-up and extending the unit’s lifespan.
Unmatched Quality and Assurance
Backed by a limited lifetime warranty, the MS90E is designed and manufactured in the USA to meet rigorous safety standards, including US and Canadian UL, CE, and NOM certifications.
