37:T694,We recently remodeled 3 bathrooms and we are so happy with all the Hansgrohe product.This iBox is genius... To fully appreciate it, you'll need to watch a video at the Hansgrohe website where they animate this iBox for various configurations. It is just plain genius. Hansgrohe made it simple that this is the only thing you use for shower / tub connect... you want a shower only, use the iBox... you want a shower / tub combo, use the iBox... you want a hand-held shower and jets on the wall, use the iBox. You get the idea.Installation is easy but requires attention. Because this is German/European, they do things a little differently than us Americans, and thus your American (I'm assuming) contractor / plumber.First, you have to make sure that it is installed in the proper position... Although it can rotated 180 degrees without consequence, it cannot be rotated 90 degrees. There is actually the word "Top" on top, which my contractor missed. He installed the top to the right instead, so he had to re-do it.Second, all the connections are screwed / twisted on instead of solder like other brands. You'll melt the plastic if you use solder nearby! My contractor soldered all the pipe (short segment) and 90 degree bend connectors elsewhere first, and then twisted them on... this iBox looked like an octopus (with 4 legs instead of 8) when it was installed. Then you can solder those
