I need a 14 inch rough in toilet that's no more than 25 inches in length from the back of the tank to the front of the bowl.

Can some suggest a brand and model?

Adam, don't use your full name on the internet. Bad practice!
Now Tell us more about your problem. Why a 14" bowl? Why no more then 26 inches front to back? Let's have some details. Tom

Hmmmm... I think they don't make such a small toilets. Answer Tom's question. Maybe we can come up with different solution...
