The unit uses advanced Power Clean technology that simplifies maintenance by enabling automatic cleaning, helping keep the generator running smoothly with minimal hassle.

It is designed for use with Kohler's dtv+ showering system; however, the necessary control kits are sold separately, which may add to the setup cost and complexity. Installation requires some planning since it needs proper integration with your existing shower space and water supply, and it weighs around 50 pounds, so professional installation is recommended. The stainless steel construction suggests good durability over time.

This model provides excellent steam output and easy cleaning, though the need for additional control components and professional installation might be a drawback for some. If you want a reliable, fast-acting system for a custom or large steam shower and don’t mind the extra setup requirements, this model fits those needs well.

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.
