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.

One of the standout features is the iTempo Control, which allows users to easily adjust steam settings, enhancing convenience. Additionally, the included Aroma Steam Head offers the option to enjoy aromatherapy, adding a soothing scent to your steam experience. The auto flush valve is another practical feature that helps maintain the generator's cleanliness and longevity, reducing the need for extensive maintenance.

There are a few considerations to keep in mind. The installation could be a bit challenging for those who are not handy, as it requires proper plumbing and electrical connections. This might necessitate hiring a professional, which could increase costs. The generator also weighs 40 pounds, making it somewhat cumbersome to install without assistance. The unit operates on 236 volts, which could also be a consideration for homes without appropriate electrical setups.

The KOHLER K-5533-NA Invigoration Series 13kW Steam Generator is an excellent choice for those looking to create a luxurious steam shower experience at home or in a commercial setting.

Additionally, the power clean technology offers hassle-free maintenance with one-touch automatic cleaning, ensuring the generator remains in good working order with minimal effort from the user. This feature promotes durability and longevity, which is essential for a device used regularly. One downside is the additional requirement of the KOHLER control kit or the DTV+ steam adapter kit, which are sold separately. This adds to the cost and could be an inconvenience for some users.

The generator operates quietly, which is an advantage for a relaxing steam shower experience. The KOHLER K-5533-NA is a powerful, efficient, and low-maintenance steam generator ideal for both residential and commercial use, but users should be prepared for additional costs and potential professional installation.
