Elongated versis regular(round)?
In the 1-piece Ultramax/Ultimate series, I sell 80% elongated and 20% round.
In the 2-piece Drake series, I sell 78% elongated and 22% round.
Of the elongated Drakes, 21% are ADA height.
In the beginning I was rather sneaky. When a woman would call for a toilet, I would quote the same price for both the elongated bowl and the round bowl. I suggested that her husband would prefer it. (I knew he would!)
Days later the husband would call himself and order two more elongated toilets.
Even though I was making less money on the firstsale, I wound up selling many more toilets because of it.
The toilets were selling themselves after that.
The guys would call up saying things like,
"I didn't know I could get those for my home"
"I didn't know I wanted it until I tried it."
"Why don't they make all toilets like that?"
"I like not having to tuck it in."
How much more space does elongated take?
You sit in the same location, it's just that you have more room up front where it matters.
The reason your builder installs round front, is not to be nice, they're cheaper!
The reason they were round in the first place was:
Hey, at least it's not an outhouse anymore!
The idea of having plumbing inside the house was strange.
Heck! Now the house seemed smaller with all those fancy pots and tubs in there.
But consider, if you have a standard tub in a bathroom, you have plenty of space next to it for an elongated bowl. The new ones are pretty compact anyway with the smaller tanks.
An alcove give more than enough space except in the rare instance.
