What Is a Steam Shower Generator?

A steam shower generator is the boiler unit that turns water into steam and pipes it into a sealed shower or steam room enclosure. It installs in a closet, vanity, or mechanical space near the shower, connected by a steam line to a steam head inside the enclosure. This is different from an all-in-one unit like a Maya Bath steam shower, where the generator is already built into the enclosure. A separate generator like Mr. Steam is the standard choice when you are building or converting a custom shower into a steam room.

Generators are sized in kilowatts (kW) to match the cubic footage of the sealed shower enclosure, not the whole bathroom. Sizing too small means weak, inconsistent steam. Sizing too large wastes energy and can overwhelm a small enclosure.

Frequently Asked Questions

What size MrSteam generator do I need?
Sizing is based on the cubic footage of the sealed shower enclosure, not the bathroom. Most single home showers use 6 to 9 kW. Call 866-861-6317 with your enclosure dimensions and we confirm the right model.
What is the difference between MS-Series and CT-Series?
MS-Series generators are built for home bathrooms, ranging 5 to 9 kW. CT-Series generators are built for commercial and spa installations with daily, multi-session use, ranging 6 to 12 kW.
Do I need a control package too?
Yes, a generator needs a compatible control package and steam head to operate. Packages like AirTempo, iTempo, and iSteamX add wireless, app, or voice control. Confirm compatibility with your generator before ordering.
Can I install a MrSteam generator myself?
Generator installation involves electrical and plumbing connections and is typically done by a licensed contractor. Confirm local code requirements before ordering.
What is the difference between MrSteam and an all-in-one steam shower?
MrSteam is a standalone generator for a custom-built or existing shower enclosure. An all-in-one unit like a Maya Bath steam shower has the generator built into a complete enclosure, which is simpler to install but less customizable.
