As a member of the Steamist Plus series generators, the Steamist SMP-15 provides homeowners with pleasant and consistent steam bathing experiences.

Durably constructed of corrosion-resistant stainless-steel, the SMP-15 provides years of maintenance-free operation. The generator is equipped with professional grade parts and heating elements to ensure the optimal performance of the unit. The SMP-15 steam generator features SteadySteam technology to maintain the user’s temperature preferences each bathing session.

The compact design of the generator allows the unit to be installed conveniently out of site. Typical installation locations include vanities, closets, insulated attics, and basements.

The Steamist SMP-15 has a 15-kilowatt power rating. The generator is available in 208V/240V 1-phase (PH) configurations and 208V, 3-phase (PH) configurations.

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

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

The Steamist SMP15 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 bathing needs.
