Steam Shower Generators for Spa-Level Home Wellness
Create luxurious, humidity-rich heat therapy at home. MrSteam eSeries generators are efficient, quiet, and sized for enclosures from compact to large rooms. Match kW to your adjusted cubic feet (ACF), choose your control, and plan a simple water, drain, and power run.
Efficient by design: Many models use less than ~2 gallons of water per 20-minute session.
Flexible installs: Locate the generator up to ~60 ft from the shower (closet, cabinet, under bench, insulated attic).
Right-sized steam: From 5kW for small stalls to 20kW for large enclosures—use ACF to size correctly.
Upgrade options: Add AutoFlush/Auto Drain, AromaTherapy, ChromaTherapy, and app controls.
Frequently Asked Questions
How do I size a steam generator?
Measure length × width × height (cubic feet). Review enclosure materials and design, then use the product’s ACF guidance to select kW. When in doubt, size up within the recommended range.
What’s ACF and why does it matter?
ACF = Adjusted Cubic Feet. It accounts for room size and finishing materials to ensure the generator produces sufficient steam. Each model lists a max ACF to guide selection.
How far from the shower can I place the generator?
Typical eSeries installations allow placement up to about 60 ft away for flexible routing (check your model’s manual for specifics).
What voltage do these require?
Most residential MrSteam eSeries units run on 240V single-phase; certain models also support 208V. Always follow the spec sheet and engage a licensed electrician.
How much water is used per session?
MrSteam eSeries generators typically use less than ~2 gallons for a 20-minute session—surprisingly water-efficient for the heat you feel.
Are controls included?
Controls are generally sold separately. Compatible options include iTempo/iTempoPlus, AirTempo, and SteamLinx app control (model-dependent).
Where should the steam head and control go?
A common layout is the steam head low and away from the primary seating area; the control at a comfortable reach/eye level. Follow brand diagrams and local code.
Do I need AutoFlush/Auto Drain?
Optional AutoFlush automatically drains after use to help reduce mineral build-up and extend longevity—highly recommended in hard-water areas.
Can I install the generator inside the steam room?
No—install outside the wet zone in a ventilated, serviceable space like a closet, cabinet, or insulated attic (per model guidance).
What are typical dimensions of the units?
Compact eSeries (5–9kW) are about 14.5"×6.75"×14.75"; 12kW ~17"×7-7/8"×18-1/2"; 20kW ~27-5/8"×20-3/4"×7-7/8". See compare table below for quick reference.
What maintenance is required?
Wipe the enclosure after sessions, allow drying, consider AutoFlush, and periodically inspect connections. In hard-water regions, follow descaling recommendations.
What about warranty?
MrSteam eSeries units include strong warranty coverage (often limited lifetime on core components). See each product page for exact terms.
