All I know is that I saw some in Norway where the horn came out as a separate pipe, downward facing, at the back of the stool and ended maybe 2" below floor level. It fit into a rubber ring on the sewer pipe. No flange, flexible joint between stool and pipe, anchoring entirely separate from the plumbing connection.
Many places in Europe have the toilet drain come out of the wall, maybe 6" above the floor. The toilet has an outlet at a similar location. The two are connected with a three-lipped rubber boot. One lip goes inside the porcelain of the toilet. one lip around the outside of the porcelain, and the third lip wraps around the drain pipe.
Some of the old designs are hard to change. All the manufacturers would have to switch over and there are fair amount old curmudgeons that don't like change.
I think a worthwhile change that mfgrs could pull off fairly easily is to have a separately mounted base of composite plastic. Fit that to the drain, secure it to the floor, then drop the stool on top and bolt to the base. The connection to the floor drain could thus be made after the base was in place, using ones choice of gasket schemes. The base could even have adjustable shims built in to allow it to be leveled.
If your view never changes you're following the wrong leader
I agree. From what I've seen, the plumbing industry is very slow to change.
Dan,
That's pretty close to Toto's arrangement. Or at least the one I installed in my house.
What Panic said...Toto already does it that way.The Japanese have engineered better cars and toilets then we in the US have.
