A steam shower can add a warm, spa-like experience to a bathroom, but the products below are steam generators—not complete shower-and-Jacuzzi-tub combinations. You’ll need a compatible steam enclosure and, if you want a whirlpool tub, a separate tub and its own plumbing and equipment. The right generator depends on your shower’s size, finish materials, electrical service, and preferred controls. Use this guide to compare five options and see what to check before buying.

CGOLDENWALL 9KW: Adjustable Controls and Automatic Drainage
This CGOLDENWALL unit is a steam generator for a separate shower enclosure, not a tub or an all-in-one bath system. Its listed features include a touchscreen controller, a steam head with an aromatherapy reservoir, and a dual-tank design. The controls let you set the temperature from 95 to 131°F and choose a working time from 30 minutes to 12 hours.
Automatic drainage is a useful convenience: the product description says the system drains water and limescale 15 minutes after use. It also lists automatic water inlet, water-shortage and overheat protection, and diagnostic prompts. The compact design is intended for installation in a nearby small space, such as a vanity or closet, but the generator still needs a suitable location and correctly planned connections.
The main limitation is that the supplied details don’t state a recommended steam-room volume or electrical requirements for this model. Don’t choose it based on the 9KW label alone. Have an installer confirm that its output suits your enclosure and that your electrical service can support it. You’ll also need a separate Jacuzzi-style tub if whirlpool bathing is part of your plan.
Pros:
- Temperature and working-time settings are adjustable.
- Automatic drainage is designed to reduce standing water and limescale buildup.
- Includes a touchscreen control and aromatherapy steam head.
- Compact design allows placement near the shower.
Cons:
- The supplied product details don’t give a room-capacity recommendation or wiring specification.
- It does not include a Jacuzzi tub or a complete steam enclosure.
Verdict: Consider this model if its installer-confirmed output fits your steam enclosure and you value adjustable controls and automatic drainage.
JJFFTAO 15KW: Higher-Output Generator With Self-Draining Operation
The JJFFTAO is a 15KW generator described for household and commercial use. Its listed controls allow temperature settings from 95 to 131°F and run times from 30 minutes to 12 hours. It also has an LCD display, a stainless steel liner, automatic water filling, and a self-draining function intended to empty the tank after use.
The feature list includes water-shortage, overheating, and overvoltage protection, plus fault-diagnosis prompts and a cleaning port. The product description says it uses two hot wires and does not require a neutral wire, with current of at least 70A. Treat those figures as product information to verify—not a substitute for an electrician’s assessment of your home wiring, breaker, and local requirements.
Its 15KW output makes correct sizing especially important. A more powerful generator is not automatically a better fit for every shower, and the supplied information does not provide a room-volume limit. Confirm the enclosure requirements and installation plan before purchasing. Like the other options here, this is only the steam component; a whirlpool tub is a separate purchase and installation.
Pros:
- Self-draining operation and automatic water filling are listed features.
- Offers adjustable temperature and working-time settings.
- Includes a stainless steel liner and a cleaning port.
- Lists several protective and diagnostic functions.
Cons:
- The stated electrical requirement calls for careful professional review.
- The supplied details don’t specify a recommended enclosure volume.
Verdict: This is a potential fit for a suitably sized installation with adequate electrical service, but confirm both with a qualified professional before choosing its higher output.
Mr. Steam MS-400-E: A Clear Room-Capacity Reference
The supplied product information identifies this as a Mr. Steam MS-400-E steam bath generator package for rooms up to 360 cubic feet. That capacity figure gives you a concrete starting point for comparing the unit with your planned steam enclosure. Measure the room and confirm that the manufacturer’s sizing guidance applies to your layout and materials before ordering.
Unlike the other products in this group, the provided details don’t describe its controls, drainage, included accessories, or wiring requirements. Don’t assume those features based on the model name or the word “package.” Check the full listing and manufacturer information to see what is included and what you may need to buy separately.
This generator is not a tub, shower enclosure, or whirlpool system. If you want a steam shower beside a Jacuzzi-style tub, plan those as separate components and make sure the bathroom layout, water connections, electrical work, and moisture control are designed together.
Pros:
- Lists a room capacity of up to 360 cubic feet.
- Provides a useful starting point for matching generator capacity to enclosure volume.
- Sold under the Mr. Steam brand.
Cons:
- The supplied information doesn’t detail controls, drainage, or electrical requirements.
- Confirm the package contents and installation needs before purchase.
Verdict: Choose this option for further consideration if your measured enclosure falls within the stated capacity, then verify the specifications and package contents with the seller or manufacturer.
CGOLDENWALL 6KW: Compact Generator With a Waterproof Control
This 6KW CGOLDENWALL model is a home steam generator with a waterproof digital control and an aromatherapy steam head. Its listed temperature range is 95 to 131°F. The product description says the unit warms up in three to five minutes and automatically drains after a steam session, with drainage also intended to clear water and limescale.
The description gives a specific US wiring connection: 8 AWG wire and a 40-amp GFCI breaker, with two hot lines and one ground line. Electrical installation should be handled and checked by a qualified electrician, who can confirm the requirements for your home and local code. The compact design is intended for installation in a small nearby space, but you still need to follow the product’s placement and ventilation instructions.
Lower output may suit some smaller enclosures, but the supplied details don’t include a room-capacity figure. CGOLDENWALL’s separate 10.5KW model provides a calculation based on enclosure volume and finish material; do not assume that formula or its result automatically applies to the 6KW model. Get model-specific sizing guidance before deciding.
Pros:
- Includes a waterproof digital control and aromatherapy steam head.
- Automatic drainage is designed to reduce manual cleanup.
- Product information provides a specific wiring and breaker reference to discuss with an electrician.
- Compact design can fit in a nearby installation space.
Cons:
- No enclosure-capacity recommendation is included in the supplied details.
- It does not include a tub or the full steam-shower enclosure.
Verdict: This model is worth considering for a smaller steam-shower plan only after you confirm that 6KW is appropriate for your enclosure.
CGOLDENWALL 10.5KW: Complete Steam Kit With Sizing Guidance
This 10.5KW CGOLDENWALL kit includes a waterproof digital control, an aromatherapy steam head, an automatic drain valve, and a cable, according to the supplied description. It lists a temperature range of 95 to 131°F and says the generator is designed to distribute steam in three to five minutes. Its automatic drainage feature is described as activating 15 minutes after use.
One practical advantage is that the product information provides a sizing method that accounts for shower volume and finish material: it gives different multipliers for ceramic tile or glass, marble, and acrylic. Use that guidance as a starting point, then confirm the calculation with the manufacturer or installer. The listed US wiring information calls for 6 AWG wire and a 70-amp GFCI breaker; have an electrician verify the actual installation requirements.
The product description also lists water-shortage and overheat protection, a reinforced stainless steel tank, a one-year warranty, and lifetime technical support. These are useful details to check against the exact listing and warranty terms. This is a generator kit, not a complete Jacuzzi-tub package, and its comparatively high electrical requirement can make installation more involved than choosing a unit by output alone.
Pros:
- Includes a control, steam head, automatic drain valve, and cable.
- Provides sizing guidance that accounts for enclosure volume and finish material.
- Lists automatic drainage and safety protections.
- Includes stated warranty and technical-support terms in the product description.
Cons:
- The listed 70-amp GFCI breaker and wiring call for professional electrical planning.
- A separate shower enclosure and any Jacuzzi-style tub must be purchased separately.
Verdict: This is a strong option to investigate if its sizing calculation matches your enclosure and an electrician confirms that your home can support the specified electrical setup.
How to Choose a Steam Generator for a Steam Shower and Jacuzzi Tub
Confirm You’re Buying the Right Components
A steam generator heats water to create steam for a sealed, steam-rated shower enclosure. It does not create whirlpool action in a tub. A Jacuzzi-style tub requires its own tub, plumbing, and equipment. Before ordering, list the parts you still need, including the enclosure, steam door, generator, controls, steam head, and tub system. Check whether each generator listing includes the parts you expect.
Size the Generator to the Enclosure
Start with the inside dimensions of the planned steam enclosure and calculate its volume. Then follow the generator maker’s sizing instructions. Wall and ceiling materials can affect the required output, so don’t compare units by kilowatts alone. The 10.5KW CGOLDENWALL description, for example, provides different sizing multipliers for different finish materials. For the other models, ask the manufacturer or installer for model-specific guidance if a capacity limit is not listed.
Check Electrical Requirements Before You Buy
Steam generators can have substantial electrical demands. The supplied specifications for the 6KW CGOLDENWALL, 10.5KW CGOLDENWALL, and 15KW JJFFTAO list different wiring or breaker information. Do not assume your existing bathroom circuit is suitable. Ask a qualified electrician to confirm the wiring, breaker, grounding, disconnects, and local code requirements for the exact model and installation.
Look at Drainage and Cleaning Needs
Self-draining systems can reduce the water left in a generator tank after use. Several options here list automatic drainage, while the CGOLDENWALL descriptions also mention clearing limescale. Check how the drain connects, where the water goes, and whether the unit still needs periodic cleaning or descaling. Automatic drainage is a convenience, not a substitute for following the maker’s maintenance instructions.
Choose Controls and Run-Time Settings You’ll Use
Consider where the controller will be installed and whether its listed features match your routine. The CGOLDENWALL 9KW, 6KW, and 10.5KW models list digital controls, while the JJFFTAO has an LCD controller. Several descriptions list settings from 95 to 131°F and run times from 30 minutes to 12 hours. Confirm that the control is compatible with your planned installation and that the settings suit your needs.
Plan for Moisture, Access, and Service
A generator may sit in a closet, vanity, or another nearby space, but its location needs to follow the manufacturer’s instructions. Plan for safe access to the unit, plumbing connections, drainage, and electrical service. The shower enclosure also needs to be designed for steam and moisture. Have the bathroom layout reviewed before construction so the steam shower, tub, and surrounding finishes work together.
Verify Availability, Included Parts, and Support
Listings and stock can change, and product pages may not include every installation detail. Check whether the exact model is available, what accessories come in the box, how warranty coverage works, and how to contact technical support. This is especially important for the Mr. Steam model in this comparison because the supplied product information gives its room-capacity limit but few other specifications.
Frequently Asked Questions
Do these products include a Jacuzzi tub?
No. They are steam generators or generator packages for a separate steam shower. You’ll need to buy a whirlpool tub and its related equipment separately if you want one.
Can I use a steam generator with any shower?
No. The shower must be designed as a steam enclosure, with appropriate construction and components. Ask a qualified installer to confirm that your planned enclosure is suitable before purchasing a generator.
How do I know what generator size I need?
Measure the enclosure and follow the manufacturer’s sizing guidance, including any adjustments for the wall and ceiling materials. If the listing does not provide a capacity recommendation, ask the manufacturer or a qualified steam-shower installer to size the model for you.
Is automatic drainage important?
It can make routine care easier by draining water from the generator after use. Check the product instructions for how drainage works and what cleaning or descaling is still required.
Can I install a steam generator myself?
These products involve plumbing and electrical connections, and some list high-amperage electrical requirements. Use qualified professionals to confirm the installation, wiring, drainage, and applicable local code requirements.
Which option provides a stated room-capacity limit?
The supplied listing identifies the Mr. Steam MS-400-E as suitable for rooms up to 360 cubic feet. Confirm the manufacturer’s sizing guidance for your exact enclosure before buying.
Which generator is the best choice overall?
There isn’t one best choice for every bathroom. The 10.5KW CGOLDENWALL includes sizing guidance in its product description, the Mr. Steam listing provides a room-capacity figure, and other models list features such as automatic drainage or adjustable controls. Match the generator to your enclosure and electrical service rather than choosing by output alone.
Final Recommendation
For a steam shower planned alongside a Jacuzzi-style tub, treat the generator, enclosure, and tub as separate parts of one bathroom project. The CGOLDENWALL 10.5KW stands out in this group for its listed sizing guidance and included kit components, while the Mr. Steam MS-400-E provides a stated room-capacity limit. Neither should be ordered until you confirm enclosure sizing, electrical requirements, availability, and package contents with the seller or a qualified installer.
