10 Best Steam Shower Generator 2026 in the United States

The Delta Faucet SimpleSteam 10kW Steam System Kit is a solid choice for anyone looking for a reliable steam shower generator. Its 10kW power rating is suitable for medium-sized steam showers, effectively providing ample steam output while maintaining a manageable water usage rate. The inclusion of smart controls adds convenience, allowing users to easily manage their steam experience with digital precision.

One of the standout features of this system is its compact, space-saving design. It can be installed in tight spaces such as a vanity, closet, or attic, making it a flexible option for homes with space constraints. The matte black finish gives it a sleek, modern look that can match various bathroom decors. Users have rated the product highly, with a 4.7 out of 5 stars, indicating a strong satisfaction with its performance and reliability over time. However, it's worth noting that the generator pan and auto drain—which could enhance maintenance and longevity—are not included and must be purchased separately. The kit requires a 240V installation, which is standard but something to be aware of during setup.

Additionally, while noise levels aren't specified, the Delta brand is known for producing relatively quiet systems, which is an essential factor for a relaxing steam experience. The Delta Faucet SimpleSteam 10kW Steam System is perfect for users who need a powerful, yet compact steam generator with modern controls. However, potential buyers should consider the additional cost of accessories like the generator pan and auto drain for optimal performance and maintenance.

The Delta Faucet SimpleSteam 15kW Steam System Kit offers a powerful steam generator suitable for home steam showers, with a solid 15kW power rating that can quickly produce steam. It comes as a complete kit including a digital square control and square steam head, all finished in stylish matte black for a modern look. The generator’s compact design allows flexible installation options—whether in a vanity, closet, attic, or basement—which is great if space is limited. It operates quietly, adding to a relaxing steam experience.

The system’s stainless steel construction helps with durability and long-term maintenance, and Delta backs it with a limited lifetime warranty, giving added peace of mind. On the control side, the digital square system is straightforward to use, though some users might find the controls a bit minimal if they want more customization. Installation requires some assembly and a 240-volt power supply, which might need professional help if you’re not familiar with electrical work.

Accessories like the recommended generator pan and auto drain are sold separately, which adds to the overall cost. This steam generator kit is a great choice for someone wanting a reliable, stylish, and powerful unit with flexible installation options, but keep in mind the need for proper installation and possible extra purchases.

The KOHLER 5531-Na Invigoration Series 11kW Steam Generator is a powerful option for residential steam showers. Its fast-response technology allows it to produce steam within 60 seconds, offering a quick and luxurious shower experience. The power clean technology ensures the generator is easy to maintain with one-touch automatic cleaning, adding to its convenience and durability.

With an 11kW power rating, it is suitable for custom showering applications up to 317 cubic feet in volume, making it versatile for various bathroom sizes. However, it requires additional components for control (sold separately), which could be an extra cost to consider. Installation could require professional assistance due to the electrical requirements, but the included installation and care guide should be helpful.

The product is also compatible with KOHLER's advanced dtv+ showering system, enhancing its functionality further for tech-savvy users. Despite being a bit heavy at 28.7 pounds, it is a solid choice for those looking to upgrade their home shower experience with a reliable and efficient steam generator.
