Crane and I think it is Kohler make a residential wall hung toilet. Both are expensive for what you get, a basic toilet. I bought the Crane because it's price was less outrageous than the Kohler, about $500 versus $630. Even so, this is probably cheaper than changing over you installation. Only a fool would install a wall mount if it wasn't necessary, so there is most likely some reason for your installation. Even if you could go to a standard bottom discharge, you may have a significant plumbing and wall/ceiling repair to move the waste pipe from the wall to the floor.

If you need a wall-mount, I wouldn't give the Crane I bought high marks; my $107 dollar Toto flushes better. The Kohler used a Sloan Flushmate for a pressure flush. You may want to consider it if the noise and cost doesn't bother you.

: I need to replace a toilet in my condo. The old toilet is a Briggs, and it has a rear output to the wall, versus the floor. It was installed in 1987. Is there a replacement out there at a reasonable cost; or, would it be cheaper to have the plumbing redone to accomodate a floor installation.
