10 Best Steam Showers 2025 in the United States

The Delta Faucet SimpleSteam 15kW Steam System Kit is a robust option for anyone looking to enhance their home steam shower experience. With a steam generator power of 15 kW, this system is designed to deliver plenty of steam for a refreshing and relaxing shower. One of its strengths is the compact design, which allows for installation in tight spaces like a closet or insulated attic, making it versatile for various setups. The included square digital control panel is user-friendly, letting you adjust settings easily.

In terms of build quality, it's made from stainless steel and tempered glass, which not only assures durability but also adds a sleek finish with its Lumicoat Chrome.

However, there are some drawbacks to consider. The generator is relatively heavy at 40.6 pounds, so installation may require some effort or professional assistance. Additionally, while the kit includes key components like the steam head and control, the recommended generator pan and auto drain must be purchased separately, which could lead to additional costs.

For those looking to invest in a steam shower system, the Delta Faucet SimpleSteam 15kW Steam System Kit could be an excellent choice, especially for users valuing power and compact installation. Just keep in mind the extra accessories needed and factor in the installation process.

The KOHLER 5531-NA Invigoration Series steam generator is a solid choice for residential steam showers, especially if you want quick steam with minimal wait time. Its fast-response technology can fill a shower enclosure up to 317 cubic feet with steam in just about 60 seconds, which is faster than many other units. The 11 kW power rating is suitable for medium to larger sized showers, ensuring strong and consistent steam output. The stainless steel construction adds durability and a sleek look, while the included Power Clean technology makes routine cleaning easier by allowing one-touch automatic maintenance, helping prevent buildup and keeping the system safe.

This unit requires separate purchase of the control kit or steam adapter kit to operate, which means additional costs and installation steps. It is compatible with KOHLER’s advanced dtv+ showering system, offering more customization if you have or plan to get that system. The generator itself is compact and lightweight at under 30 pounds, making installation manageable, but it does need proper ventilation and electrical setup to meet safety needs.

Seating and comfort depend on your chosen shower setup, as this is just the steam generator unit. If you want a reliable steam generator that heats up fast and has easy cleaning features, and you’re okay with buying controls separately, this KOHLER model is a dependable option for enhancing your home steam shower experience.
