Sizing Your Steam Shower
The 32325-NA is rated for steam showers up to 112 cubic feet. Use our steam generator sizing calculator, which accounts for ceiling height, or send us your shower dimensions and we'll confirm the right size.
Installation & Space Requirements
Professional installation required. It needs a dedicated 240 V circuit. Kohler specifies that no GFCI be used on generator circuits. Install in a well-ventilated, temperature-controlled location. See the installation manual for breaker sizes and full requirements.
What You'll Also Need
- A control: the Kohler 5557 Invigoration control kit with round steam head (other finishes available), or the Kohler 32312 steam controller with a 32310 square or 32309 linear steam head
- Or buy the generator, control kit and drain pan together in the Kohler All-In-One Steam Shower Package
Common Questions
Which control does it use?
Single Kohler generators use the Kohler 5557 Invigoration control kit (round steam head), or the 32312 steam controller paired with a square (32310) or linear (32309) steam head. Our Kohler All-In-One package pairs the generator and control for you.
Does it shut off automatically?
Yes. For safety, it shuts down after 20 minutes unless you restart it.
Is 7 kW the right size for my shower?
Use our steam generator sizing calculator; ceiling height changes the size you need. Email us if you'd like us to check your numbers.
