The Function and style are excellent! To be more specific, the plumbing for the unit concealed within the unit. The hotcold plumbing lines are brought out of the wall to be connected to the regulator valve body which meant that there were very small openings in the wall (easy to seal up). The unit has 3 points for unit to hang from ( again minimally invasive to the wall ). Should I need to service it, easy to get to the mechanics without opening up the tile wall. 
Design wise, very attractive. Can’t wait to try it out!
