SM Plus Series 5kW Steam Shower Generator


The Steamist SMP-5 5kW steam shower generator is engineered for use in home steam baths up to 100 adjusted cubic feet (ACF).

Required operating control sold separately.

Steamist SM Plus steam generators are known for safe, reliable, and efficient operation.

When designing this product, Steamist focused on providing homeowners with a consistent and pleasurable steam bathing experience. The Steamist SMP-5 generator is made of durable stainless-steel and equipped with industrial-grade parts for years of maintenance-free operation. The unit features SteadySteam technology to maintain the user’s temperature preferences each bathing session.

The compact size of the generator allows the unit to be conveniently installed out of sight. Typical installation locations include vanities, closets, insulated attics or basements.

The Steamist SMP-5 steam generator has a power rating of 5 kilowatts and is available in 240V and 208V single-phase (PH) configurations.

Select the Steamist operating control with features that best suits your bathing preferences. A Steamist control or control package is required for operation and is available in a variety of luxurious finishes.

We highly recommend the Steamist Auto Drain valve to help prevent harmful mineral buildup and calcification of the heating elements and reservoir. The drain valve automatically drains the steam shower system after the water cools, protecting the longevity of the generator. For added convenience, the Auto Drain may be used with the available Steamist Generator Drain Pan.

The Steamist SMP5 carries a limited lifetime warranty and is fully serviceable. All Steamist SM-Plus residential steam generators are UL and CUL listed for unmatched quality and safety. Steamist SM-Plus generators are available in a variety of power ratings to best suit your needs.
