The current design of the Nebia Spa Shower 2.0 does not allow you to use the wand without having the main head on. This choice was made to allow the wand and head to run simultaneously while still meeting regulatory needs. With Nebia 2.0 the shower head will always be on, but you'll enjoy a hotter shower, better coverage, more power, added colors, and less humidity. Lastly, thanks to the revamped pressure regulator, Nebia 2.0 now works in homes with well-below-average water pressure (as little as 20 psi) while still providing a great shower experience.
