Sizing Your Steam Shower
The 32335-NA is rated for steam showers up to 1,000 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. As a tandem unit, it needs two dedicated 240 V circuits, one for each generator, and two drain pans. 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 Kohler 5558 Invigoration tandem control kit (other finishes available), or a KOHLER DTV+ tandem steam adapter kit
- Or buy the generator, control kit and drain pans together in the Kohler All-In-One Steam Shower Package
Common Questions
Why does it need two circuits?
The 32335-NA is a tandem unit: two 15 kW generators working together, each on its own dedicated 240 V circuit with no GFCI.
Which control does it use?
Tandem Kohler generators use the Kohler 5558 Invigoration tandem control kit. Our Kohler All-In-One package pairs them for you.
Is 30 kW the right size for my shower?
