FAQ

How many kW do I need for my steam shower?

The required kW depends on the cubic footage of your shower and the material of your walls (tile, stone, or glass). As a general rule, stone walls require more power than acrylic or tile due to their heat-absorbing properties.

How often does a steam generator need maintenance?

Depending on your water hardness, you should perform a manual flush every few months if your unit does not have an automated system. This ensures the longevity of your heating elements.

Can I install a steam generator in an existing shower?

Yes, but it requires a specialized steam door to keep the steam inside and proper insulation. Consult with a contractor before purchasing to ensure your enclosure is vapor-proof.
