A steam shower kit can add on-demand steam to a properly built shower, but the right choice depends on more than wattage. You’ll also want to check what comes in the kit, how the generator drains and is maintained, and whether your bathroom’s electrical setup can support it. These five options range from a 9kW aromatherapy-focused kit to higher-output systems, with different controls and maintenance features.

Our Picks: Best Steam For Shower Kits reviews
1. Delta Faucet SimpleSteam: A Streamlined 10kW System
The Delta SimpleSteam kit pairs a 10kW generator with a square digital control and a square steam head. Its compact generator is designed for installation in a vanity, closet, insulated attic, or basement, which gives you a few options for planning around the shower.
The kit includes a 35-foot cable. An extension cable for a different cable length is sold separately, and the recommended generator pan and auto drain are also separate purchases. Factor those details into your installation plan rather than assuming every supporting part is in the box.
This is a practical pick if you want a coordinated control and steam head from a familiar faucet brand and have confirmed that 10kW is appropriate for your project. Compared with the feature-heavy VEVOR and SteamSpa options, the listed SimpleSteam details are more focused on the core system than on added automation or quick-start claims.
Pros:
- Includes the generator, square digital control, and square steam head.
- Compact design allows several possible generator locations.
- Comes with a 35-foot cable.
- Offered in several generator sizes, according to the product description.
Cons:
- The recommended generator pan and auto drain are sold separately.
- A different cable length may require a separately sold extension.
Verdict: Choose the Delta SimpleSteam if you want a compact, brand-name 10kW kit and are comfortable sourcing the recommended drain pan and any extra cable separately.
2. VEVOR 12kW Generator: Flexible Controls and Automatic Drainage
This VEVOR kit is a 12kW steam generator with a touch control, adjustable temperature, and a 24-hour timer. Its listed temperature range is 77–131°F, and the product description says segmented heating can produce steam in about five minutes. Actual warm-up time can depend on the installation and shower conditions.
The generator has a stainless steel tank with a magnesium rod and automatic drainage. It also lists protections against overheating, water shortage, and overpressure. These features make it a strong option if you want more built-in control and drainage functions than the basic Delta setup describes.
The listing describes the kit as having accessories for installation, but it does not itemize every accessory in the supplied product information. Check the included parts and confirm electrical and plumbing requirements before buying. The listed features are appealing, but they don’t replace professional sizing or installation advice.
Pros:
- Automatic drainage is included as a listed feature.
- Offers adjustable temperature and a 24-hour timer.
- Includes protections for overheating, low water, and overpressure.
- Stainless steel tank and magnesium rod are specified.
Cons:
- The product information does not give a detailed item-by-item accessory list.
- The five-minute steam claim should not be treated as a guaranteed warm-up time for every installation.
Verdict: The VEVOR is worth considering if its 12kW capacity suits your shower and you value a timer, temperature adjustment, and automatic drainage in the listed feature set.
3. JJFFTAO 15kW Generator: Higher Output with Self-Draining
The JJFFTAO is a 15kW steam generator with an LCD controller and a self-draining system. The controls are described as allowing temperature settings from 95–131°F and operating times from 30 minutes to 12 hours. Its stainless steel tank and built-in protections are intended to support routine use and system monitoring.
The product description specifies a 70-amp current requirement and says installation uses two hot wires, with no neutral wire required. Because this is a high-power system, have a qualified electrician confirm that your home’s electrical service and wiring can support it before you buy. The listing also describes automatic water filling, draining, and flushing.
At 15kW, this option has the highest listed output among the five, but the extra capacity is not automatically an advantage. The right wattage depends on the shower and the installation, so compare it with professional sizing guidance. This product is listed as unavailable in the supplied information, which makes it a less practical choice unless its status changes.
Pros:
- Highest listed output in this comparison at 15kW.
- Self-draining system and LCD temperature and time controls.
- Stainless steel tank and listed safety protections.
- Includes a descaling and cleaning port for models rated 6kW and above, according to the description.
Cons:
- The specified 70-amp requirement calls for careful electrical planning.
- Listed as unavailable in the supplied product information.
Verdict: Consider the JJFFTAO only if an installer confirms that 15kW is right for your shower and electrical service, and the product is available when you shop.
4. SteamSpa 12kW Premium Bundle: QuickStart and Two Steam Heads
The SteamSpa Premium Bundle combines a 12kW generator with QuickStart and continuous-steam features. Its dual-tank design is intended to provide a steady flow, while the listing describes operation as quiet. These are product claims, so actual performance may vary with setup and conditions.
The bundle includes a wall-mounted touch pad, two steam heads, and a quick connection kit. The control can set time and temperature, read room temperature, and save preferred settings. One steam head has a reservoir for aromatherapy use, adding a feature that is not listed for the Delta or VEVOR kits.
A built-in auto-drain system is designed to purge excess water and minerals after a session. That can help with routine upkeep, but it does not mean the system never needs maintenance. Compared with the VEVOR, this kit emphasizes its bundle contents, dual-tank design, and saved control settings.
Pros:
- Includes a 12kW generator, touch pad, two steam heads, and quick connection kit.
- Dual-tank design and QuickStart feature are listed.
- Control can save preferred settings and read room temperature.
- Built-in auto drain is designed to help clear water and minerals after use.
Cons:
- The product description does not provide detailed electrical requirements.
- QuickStart and quiet-operation claims may depend on the installation and conditions.
Verdict: The SteamSpa bundle is a compelling option if you want a 12kW system with two steam heads, a feature-rich control, and a quick connection kit in the listed package.
5. Hapyvergo 9kW Kit: Aromatherapy Head and Descaling Access
The Hapyvergo is a 9kW steam generator kit with a smart controller, self-draining system, and aromatherapy steam head. The head is designed to accept essential oils, which may appeal if you want that option as part of your steam setup.
The product description lists a stainless steel body, a tank with a magnesium rod, and protections against overheating, water shortage, and overpressure. It also includes a quick descaling port. The manufacturer recommends descaling every two months and says the process takes about ten minutes; follow the supplied instructions for the actual maintenance procedure.
Hapyvergo recommends installing its controller outside the shower because moisture may cause false-touch problems. That placement is worth planning before construction or renovation. The product is listed as unavailable in the supplied information, so check its current listing status before treating it as a ready-to-buy option.
Pros:
- Includes an aromatherapy steam head and smart controller.
- Self-draining system is listed.
- Has a quick descaling port and a magnesium rod in the tank.
- Lists several protective features, including overheating and low-water protection.
Cons:
- Listed as unavailable in the supplied product information.
- The controller should be installed outside the shower, according to the product description.
Verdict: The Hapyvergo makes sense if aromatherapy and accessible descaling are priorities, but confirm availability and have an installer check that 9kW is suitable for your shower.
How to Choose a Steam Shower Kit
Match generator output to your shower
These options range from 9kW to 15kW, but a higher number is not always better. The right generator depends on the shower and the installation. Ask a qualified installer to confirm the required capacity before choosing a model, rather than relying on wattage alone.
Check your electrical service before ordering
Steam generators need suitable electrical wiring and power. The JJFFTAO listing, for example, specifies a 70-amp current requirement and a particular two-hot-wire connection. Do not assume another model has the same requirements. Have an electrician review the product specifications and your home’s electrical setup.
Compare what the kit actually includes
Package contents vary. Delta lists a generator, control, steam head, and 35-foot cable, while its recommended generator pan and auto drain are separate. SteamSpa lists two steam heads and a quick connection kit. For VEVOR, confirm the exact accessory list on the product page. Check each component before purchase so you can plan for any additional parts.
Consider drainage and mineral maintenance
Automatic drainage appears on several models, but it does not remove the need to follow maintenance instructions. The Hapyvergo description calls out a descaling port and a suggested descaling routine. Delta recommends a separate generator pan and auto drain. Look for clear instructions on draining, cleaning, and scale control, especially if you want to keep routine upkeep manageable.
Plan the generator and control locations
Think through where the generator, controller, and cables will go before installation. Delta describes several possible generator locations, including a vanity, closet, insulated attic, or basement. Hapyvergo recommends placing its controller outside the shower because moisture may cause false touches. Confirm that the planned locations fit the product instructions and your installer’s requirements.
Choose controls and extras you will use
Some kits focus on core controls, while others add a timer, saved settings, temperature display, or aromatherapy features. The VEVOR lists a 24-hour timer and adjustable temperature; SteamSpa lists saved settings and an aromatherapy reservoir; Hapyvergo includes an aromatherapy steam head. Choose features that suit your routine, but treat them as secondary to correct sizing, safe installation, and complete kit contents.
Frequently Asked Questions
What does a steam shower kit usually include?
It depends on the product. A kit may include a generator, controller, steam head, cable, or installation connections. Some components may be sold separately, so check the included-items list and installation instructions before buying.
How do I know what generator wattage I need?
Have a qualified installer assess your shower and confirm the generator capacity. The wattages shown in product titles are not enough on their own to determine fit.
Does a self-draining generator still need maintenance?
Yes. Automatic drainage can remove water after use, but it does not eliminate all upkeep. Follow the manufacturer’s guidance for draining, cleaning, and descaling.
Can I install a steam generator myself?
These systems involve electrical and plumbing connections. Use a qualified professional to confirm the site requirements and complete the work safely. Follow the product’s installation instructions.
Where should the generator be installed?
The right location depends on the model and your home. Delta describes options such as a vanity, closet, insulated attic, or basement. Confirm allowable placement, access, and other requirements in the manufacturer’s instructions and with your installer.
Are aromatherapy features included with every kit?
No. The SteamSpa bundle includes a steam head reservoir for aromatherapy, and Hapyvergo lists an aromatherapy steam head. The other product descriptions do not list the same feature.
Which kit is the best choice overall?
For a feature-rich bundle, the SteamSpa lists two steam heads, a touch pad, QuickStart, and a quick connection kit. The Delta is a more straightforward 10kW option, while VEVOR adds a timer and automatic drainage. The best fit depends on your shower’s required capacity, electrical setup, and the features you want.
Final Recommendation
Start by confirming your shower’s required generator capacity and your home’s electrical requirements with a qualified installer. Among the listed options, the SteamSpa 12kW Premium Bundle stands out for its stated package contents and control features, while the Delta SimpleSteam is a straightforward choice if its 10kW capacity fits your project. The VEVOR is another option if you value a timer and automatic drainage. Check the current listing and exact included parts before ordering, particularly for products listed as unavailable in the supplied information.
