    Default Concealed tank toilet (in wall tank) Geberit / Duravit

    I am looking at Geberit in wall tank/carrier with Duravit toilet. Anyone have any experiences with these toilets? I want to put one of these in my bathroom? How hard is the plumbing and any idea how much can plumbing for this run me?
    Specs here:

    Any plumbers in the Boston area that have done these installations?

    The actual installation of this Geberit product is not too difficult but you will need a plumber. You'll also need a 6" deep wall with a 20" open stud bay. The water connection will go into the top of the tank in the wall. I usually just use a drop ear 90 (like for a shower head). The drain and vent in the underfloor are similar to a standard toilet except that instead of the closet bend coming up 12" away from the wall, it comes up in the center of your 20" stud bay and connects to the 90 provided by Geberit. The vent will have to come up to the side of your 20" stud bay (or in a different wall if there's one close enough). The carrier attaches to the bottom wall plate and the side studs with lag bolts. I don't know what plumbers charge out there but depending on how close the pipes are to the area, you might figure 6 hrs. to rough it in.
    Good Luck.
