Yes, the house was built in 1959. And the installer did say something
about the configuration of the trap or trap way having something to do
with it. However, he also said that a different type toilet would
probably fit. As an example, he said he was pretty sure a Kohler
Cimmaron would work. It's interesting that with scores of older
houses having bathroom redoes, that this never came up in this group,
especially with the wealth of knowledge and experience you guys
display daily.

If you're correct, then I'm going to have to replace the toilet with a
better fit and see if Lowe's will do anything about the install.


If Lowes won't do anything about this crappy install, your local
small-claims court will.

If all the suppositions are correct, that this house does not easily
accommodate your new toilet, the installer should have told you this within
five minutes. Had he done so, you could have exchanged the toilet or
negotiated with the plumber for a proper installation.

As things stand, you have a mess to sort out.
