Kohler Steam Generator Repair
A Kohler steam shower has three main parts: the generator (usually in an attic, closet, or vanity), the steam head in the shower, and the control on the wall.
We repair all three, whether your steam runs from an Invigoration Series control, a DTV+ interface, or an Anthem+ control. We service the current and previous Invigoration Series generators. Find your model number in the table below.

Kohler Steam Generator Repair FAQ
My steam shuts off on its own. Is it broken?
Not always. Kohler steam generators have a built-in timer that ends each session. If it shuts off much sooner than the time you set, or won't restart, it needs a look.
Where do I find my steam generator's model number?
On the label on the generator itself. Match it to the model number table on this page, or text us a photo of the label.
Where is my steam generator?
Usually in an attic, a closet, or a vanity cabinet near the shower. It has to be within a set distance of the steam head, so it's rarely far away.
Should I repair or replace my steam generator?
Most of the time a repair is enough. We test the generator, controls, and wiring first, and only recommend replacing it when a repair won't last.
Do you do Kohler warranty repairs?
Yes. We perform warranty repairs on behalf of Kohler, and out-of-warranty repairs directly for homeowners. Either way you get genuine Kohler parts.
What should I send to get a quote?
Text or email us the model number from the generator's label, a photo of the control, and a short description of what the steam is doing.
