ATF: North Trail - Bathroom Taps with Diverter

Could someone tell me where to purchase a set of bathroom taps with diverter for my 2012 NT Focus Edition FX23?
The Diverter has broken so I presume I need to replace the whole tap.
Also when are the walls of my TT going to be delivered to my importer Wainui RV NZ, This trailer has been faulty since I picked it up along with slideout leaks and rotton roof. And I am still waiting for this to be fixed.

Have you tried calling or emailing Heartland for information specific to your NT?
